Die Musik spielt in
Asien und am Golf
Asia and the Golf
region are where
it’s all happening
Die jüngsten Quartalszahlen von Alcoa, speziell
das operative Ergebnis, fielen besser aus
als von vielen Analysten erwartet – trotz des
anhaltenden Abwärtstrends bei den Aluminiumnotierungen.
Was auf der Hüttenseite
belastet, wird in der Verarbeitung offenbar
überkompensiert. Der Konzern berichtet von
einer starken Nachfrage aus der Luftfahrt-,
Automotive- und Verpackungsindustrie. Auf
der Hüttenseite reagiert das Unternehmen,
wie andere Flagschiffproduzenten à la Rusal
und Chalco, mit Produktionskürzungen und
der Schließung von Werken. Über die bereits
brach liegenden Kapazitäten von einer halben
Million Jahrestonnen hinaus prüft Alcoa
weitere Produktionsstilllegungen fast in gleicher
Höhe. In der Baie-Comeau-Hütte in
Kanada werden zwei Søderberg-Linien bis
September stillgelegt, in Italien wird die Fusina-Hütte
bei Venedig endgültig geschlossen.
Letzteres wirft erneut die Frage nach der
langfristigen Zukunft europäischer Hütten
auf, sollte aber nicht überbewertet werden,
diese Frage begleitet die europäische Aluminiumindustrie
seit mehr als zwei Jahrzehnten.
Ohnehin sind die Produktionskosten, insbesondere
die Stromkosten für Aluminiumhütten
in den EU-Ländern recht unterschiedlich,
sodass die Frage nach der Zukunft der europäischen
Hütten nicht pauschal beantwortet
werden kann. Immerhin handelt es sich allein
in Westeuropa um eine Jahresproduktion von
3,6 Mio. Tonnen Primäraluminium.
Die Erweiterung und der Neubau von
Hütten, das zeigt sich seit Jahren, findet vor
allem in China und den Golfstaaten statt.
China ist Selbstversorger, modernisiert seit
Jahren seine Hüttenstruktur, mustert kleine
und technologisch veraltete Betriebe aus
und ersetzt sie durch große, energieeffiziente
Produktionsanlagen, die internationalen
Standards entsprechen. Möglicherweise entscheidet
sich China dereinst, Hütten außerhalb
der Landesgrenzen zu bauen oder sich
an entsprechenden Projekten zu beteiligen,
zumal rohstoff- und energieseitig Engpässe
bestehen. Von den großen Hüttenbetreibern
im Land wird eine Rückwärtsintegration in der
Wertkette erwartet, um sich beim Bauxit und
Oxid abzusichern.
Am Golf schreitet der Kapazitätsausbau
weiter voran. Er zielt, vorerst noch, stark auf
den Export und die Versorgung Asiens, aber
auch Amerikas und Europas mit Primäraluminium.
Doch etabliert sich am Golf Schritt
für Schritt eine Downstream-Industrie. Die
Arabal-Konferenz im November in Abu Dhabi
wird ein Schlaglicht auf die Region und ihre
Entwicklungstendenzen werfen. Darauf darf
man gespannt sein.
Despite the continuing downward trend in
aluminium prices, the latest quarterly figures
from Alcoa were better than many analysts
had expected, especially operating income.
Difficulties on the smelter side (upstream) are
apparently being overcompensated for by the
processing side (downstream): the company
reported strong demand from the aerospace,
automotive and packaging industries. Upstream
the company reacted à la Rusal and
Chalco and made cuts in production and closed
plants. Despite having already mothballed capacity
totalling half a million tonnes a year,
Alcoa is now considering further production
closures of almost the same magnitude. Two
Søderberg lines at the Baie-Comeau smelter
in Canada will be shut down until September
and the smelter at Fusina near Venice in Italy
has been closed permanently.
The latter again raises the question of the
long-term future of European smelters but
too much should not be read into this: it is a
question that has been dogging the European
aluminium industry for more than two decades.
Production costs, and especially electricity
costs, differ quite markedly in the different
EU countries so that the question of the future
of European smelters cannot be answered in
a wholesale manner. After all, in Western Europe
alone we are talking about some 3.6m
tonnes of primary aluminium a year.
It has been apparent for some years that
the expansion of existing smelters and the
erection of new ones are mainly taking place
in China and the Gulf Arab states. China is
self-sufficient in aluminium: production and
consumption are balanced to a large extent. It
has been modernising its smelter capacity for
years and is taking small and technologically
obsolete smelters out of service and replacing
them with large, energy-efficient production
plants that are on a par with international
standards. Someday China will possibly decide
to build smelters beyond its borders or
participate in such projects, especially as there
are bottlenecks where raw materials and energy
are concerned. The country’s large smelter
operators are expected to undertake a backward
integration in the value chain in order
to safeguard supplies of bauxite and alumina.
The expansion of smelter capacity in the
Gulf Arab states is continuing apace and is
strongly oriented, at least at first, at exports
and supplying primary aluminium to Asia as
well as the USA and Europe. However, the
Gulf region is steadily establishing a downstream
industry. The Arabal conference in
Abu Dhabi in November will highlight the
region and developments there. We can look
forward to that with anticipation.

Produktion von Alufolie
legt auf breiter Front zu
Erstmals seit Mitte 2011 ist die Produktion
von Alufolie wieder in allen Dickenbereichen
gestiegen. Wie der europäische Alufolienverband
EAFA mitteilte, legte die Produktion im
ersten Quartal dieses Jahres insgesamt um 3,7
Prozent auf 209.400 Tonnen zu (2012: 201.900
t). Auch der Export der europäischen Hersteller
stieg um 10,3 Prozent an. Damit konnte
das Momentum von Ende 2012 in das erste
Quartal dieses Jahres mitgenommen werden.
Amag schließt Großvertrag
mit EADS
Die Amag Austria Metall AG mit Sitz im österreichischen
Ranshofen ist zum 1. Januar 2013
einen Großvertrag mit EADS eingegangen,
der die Lieferung von Aluminiumplatten und
-blechen für die Fertigung von Struktur- und
Außenhautteilen vorsieht. Das Auftragsvolumen
beträgt bis zu 100 Mio. Euro. Die mehrjährige
Vereinbarung umfasst die Lieferung
von Platten, Blechen und Bändern für alle
aktuellen Airbus-Flugzeugtypen.
Der Amag-Standort wird derzeit mit einem
Investitionsvolumen von 220 Mio. Euro ausgebaut,
um vor allem das Geschäft im Transportbereich
(Luftfahrt und Automobil) und
Leichtbau weiterzuentwickeln. Mit der Investition
erweitert das Unternehmen sein Portfolio
zu größeren Dicken und Breiten auch für
hochfeste Produkte in der Luftfahrtindustrie.
Für Amag-Chef Gerhard Falch ist der Auftrag
„ein weiterer Beweis für unsere hohe Kompetenz
in der Luftfahrt.“ Beide Unternehmen
arbeiten bereits seit 2005 zusammen.
Aluminium ist nach wie vor der bevorzugte
Basiswerkstoff in der Luftfahrt. Marktprognosen
von Airbus zufolge werden bis 2031
mehr als 28.000 neue Passagier- und Frachtflugzeuge
gebaut. Diese Zahl unterstreicht
die langfristigen Wachstumsaussichten für
die Luftfahrtindustrie und damit auch für den
Aluminiumbedarf. Das Marktforschungsinstitut
CRU erwartet ein beständiges Wachstum
des Verbrauchs von Aluminiumwalzprodukten
in der Luftfahrtindustrie von derzeit
390.000 Tonnen auf 536.000 Tonnen im Jahr
2017 allein für Nordamerika und Europa.
Durch die Investition in das neue Walzwerk
in Ranshofen schafft Amag die Voraussetzungen,
um am wachsenden Alubedarf in der
Luftfahrtindustrie zu partizipieren.
Oetinger insolvent
Das Aluminiumschmelzwerk Oetinger mit
Standorten in Weißenhorn, Neu-Ulm, Hannover
und Berlin hat Insolvenz angemeldet.
Zum vorläufigen Insolvenzverwalter wurde
der Düsseldorfer Rechtsanwalt Frank Kebekus
bestellt, der in der Sanierung von Aluminiumfirmen
erfahren ist. Seine Aufgabe ist nun, Investoren
zu finden um das Schmelzwerk mit
seinen 500 Arbeitsplätze zu retten.
Der Betrieb des Unternehmens wird derzeit
aufrechterhalten, Aufträge seien vorhanden,

NEW S IN BRIEF
Amag aerospace plates at the ultrasonic inspection
line where quality testing is completed several
times more quickly
Amag Austria Metall AG, based in Ranshofen,
Austria, concluded a multi-year contract with
EADS, effective 1 January 2013, for the supply
of aluminium plate and sheet to manufacture
structural and skin components. The order
Amag signs major
contract with EADS
volume is up to 100 million euros. The agreement
covers the supply of aluminium plate,
sheet and strip for all current Airbus aircraft
types.
The Austrian factory is being expanded,
with an investment of 220 million euros,
primarily to drive the commitment in transportation
(aircraft and automotive) and lightweight
construction. The investment is aimed
at extending Amag’s portfolio to include
larger thicknesses and widths also for highstrength
products for the aircraft industry.
Amag CEO Gerhard Falch commented: “This
order is further proof of our high level of expertise
in products for the aircraft industry.
Amag and EADS have been cooperating since
2005.
Aluminium continues to be the preferred
principal material for aircraft applications.
According to Airbus’ market forecasts, the
demand for aircraft will rise to more than
28,000 new passenger and cargo planes by
2031. This forecast underlines the long-term
growth prospects for the aircraft industry. The
market research institute CRU (Commodity
Research Unit) expects the consumption
of aluminium flat rolled products in the aircraft
industry to steadily grow from currently
390,000 to 536,000 tonnes in 2017 in North
America and Europe. Due to the investment
in the new rolling mill, Amag is ideally positioned
to participate in the growing consumption
of aluminium in the aircraft industry.
As the aircraft business is of growing importance
to Amag, the company presented its
product portfolio of high-strength sheet and
plate destined for the aircraft industry at the
50 th International Paris Air Show at Le Bourget
in June.
Georg Fischer receives major order from Audi
GF Automotive, a division of Georg Fischer,
has been awarded a major order from Audi,
worth more than CHF400 million. The light
structural parts for the German car manufacturer
will be produced by aluminium pressure
die casting in Europe and China starting in the
next few years.
The order comprises suspension strut
domes, which will be built into several new
Audi models and replace conventional welded
sheet metal assembling. The new design features
a better functionality and a much lower
number of components resulting in a weight
reduction of over 50 percent.
Ten production sites worldwide
GF Automotive, located in Switzerland, is
one of the leading automotive suppliers
worldwide and a development partner and
manufacturer for the automotive industry. It
manufactures some 600,000 tonnes of iron,
aluminium and magnesium at ten production
plants in Germany, Austria and China.
International Aluminium Pressure
Die Casting Competition
The German Aluminium Association GDA announces
the International Aluminium Pressure
Die Casting Competition 2014. Partners in
organising the competition are the Federation
of the German Foundry Industry (BDG) and
the European Aluminium Association (EAA).
Submissions to the competition can be made
until 31 October 2013.
For years the competition has been a
proven platform for showing off the high
standard of quality in aluminium pressure
die casting. The goal of the competition is to
strengthen interest in aluminium as versatile
working material and to demonstrate new
areas of application. Until now the aluminium
pressure die casting competition was held by
the German Association of the Aluminium
Recycling Industry (VAR), which disbanded in
March. As of 1 April the GDA puts its aluminium
recycling division into action. Initially, they
will continue the former programme of activities
of VAR, and expand it in the mid term.
This includes the die casting competition.
The evaluation criteria for cast pieces submitted
to the competition include a proper
die cast construction and the use of recycled
aluminium. Foundries can submit any number
of die cast pieces, which should be made of
an aluminium alloy commonly used in die
casting. Pieces which meet the requirements
on quality, topicality, innovative approaches to
solving problems and technical advancement
will receive awards.
The award ceremonies for the best submissions
will take place at Euroguss 2014 (14
to 16 January) in Nuremberg. The winning
pieces will be exhibited there and at other
trade fairs.
Competition forms can be downloaded in
German and English from the websites of the
associations: www.aluinfo.de, www.bdguss.de
Alufoil sees production
growth on all fronts
First quarter 2013 figures for aluminium foil
showed growth across all gauges for the
first time since mid-2011. Overall first quarter
production grew by 3.7% to 209,400 tonnes
(2012: 201,900 t). Meanwhile exports from
European manufacturers maintained the momentum
seen in the later part of 2012 with
a first quarter growth of 10.3%, according to
figures released by the European Aluminium
Foil Association (EAFA).

NEW S IN BRIEF
Mubadala and ICD establish Emirates Global Aluminium
In a move that will form a new industrial giant
in the United Arab Emirates, Mubadala
Development Company of Abu Dhabi and the
Investment Corporation of Dubai (ICD) have
announced the creation of Emirates Global
Aluminium – a jointly-held, equal-ownership
company that will integrate the businesses
of Dubai Aluminium (Dubal) and Emirates
Aluminium (Emal) – with plans for significant
local growth and international expansion.
Pending required approvals, the formal commencement
of joint operations is expected to
be completed within the first half of 2014.
Emirates Global Aluminium will be the
fifth largest aluminium company by production
when Phase II of Emal is completed mid-
2014, and will serve over 440 customers in 55
countries, with a joint production capacity of
2.4m tpy of aluminium on the completion of
Emal Phase II.
The accord builds on a successful partnership
that started with the formation of Emal in
2006, a joint venture of Mubadala and Dubal.
Emirates Global Aluminium will have an aggregate
enterprise value of more than USD15
billion and will be the fifth-largest global aluminium
company by production once Emal
Phase II is complete in the first half of 2014.
Building on the heritage of Emal and Dubal,
the new company will look to expand along
the value chain, from aluminium smelting to
alumina refining and bauxite mining overseas.
Given its scale, Emirates Global Aluminium
will also continue to attract downstream manufacturing
and ancillary businesses related to
aluminium smelting and alumina refining as it
grows, thereby indirectly creating additional
jobs.
Emirates Global Aluminium will be managed
by a board of directors that will be chaired
by H. E. Khaldoon Khalifa Al Mubarak, current
chairman of Emal, while H. E. Saeed Mohammed
Ahmed Al Tayer, vice-chairman of
Dubal, will become its vice-chair. The board
will also include H. E. Sultan Al Jaber, Abdulla
Kalban, Khaled Al Qubaisi, Ahmed Yahia Al
Idrissi, Abdul Wahed Mohammad Al Fahim;
and Khalid Al Bakhit.
The new company will be led by two wellestablished
leaders in the UAE, both veterans
in the aluminium industry. Abdulla Kalban,

Emal celebrates installation
of steel structure
for Phase II potline
Emirates Aluminium (Emal) has recently celebrated
the installation of the final steel structure
for the potline of its Phase II expansion.
With the last of 120 specially designed steel
All the major civil and mechanical work on the world’s longest single potline of 1.7 km is now complete
structures now in place, all the major civil
and mechanical work on the world’s longest
single potline of 1.7 km is now complete and
Emal remains on target to deliver its ambitious
expansion plans.
The first steel structure was raised in July
last year, which means that completion was
within the anticipated target of 12 months. The
project was also completed without a single
Lost Time Injury (LTI) – the industry standard
for measuring success in health and safety.
Emal’s Phase II expansion project will increase
primary aluminium production to 1.3
million tonnes a year by the end of 2014, from
today’s 800,000 tonnes a year. Early works
on the estimated USD4.5 billion Phase II expansion
began early in 2011, making Emal one
of the largest industrial projects in the United
Arab Emirates outside oil and gas and one of
the key projects leading to the diversification
of the UAE’s economy.
Emal has created 2,000 jobs with Emiratisation
at the core of its employment strategy,
which will rise to approximately 3,000 upon
completion of Phase II.

European Aluminium Congress 2013 – The programme is ready
The programme for the EAC – European
Aluminium Congress 2013 is ready. The
international congress with its theme
‘Aluminium Automotive
Applications –
Tomorrow’s Design and
Sustainable Performance’
will be held by the German
Aluminium Association
GDA in Düsseldorf
on 25 and 26 November
2013. The programme
of the EAC 2013 shows
presentations on possible
applications of aluminium
in motor vehicle manufacturing,
but also presentations
on further developments
with potential for
making vehicles of the
future even lighter and
more energy efficient.
Aluminium has become an
indispensable material in the motor car: castings
for engine housings, cylinder heads, and
gearbox housings or for structural parts in the
auto body. Today this is state-of-the-art. But
semi-finished products in the form of sheets,
extruded profiles and forgings
are also being used more and
more in vehicles. Some examples
of this are car body structural
parts, sheets for the outer
shell or crash-related parts,
such as bumper crossbeams or
longitudinal beam structures.
Even more examples can be
found in the form of extruded
profiles used as decorative
strips for visual enhancement,
or as safety related parts in the
area of the chassis.
The increasingly intensive
competition between the different
materials has prompted
car manufacturers and aluminium
suppliers to work
more closely together. With
its investments in application-oriented
research and development, the
aluminium industry has repeatedly improved
the characteristics of its material, developed
new products, and optimised production processes.
Innovations in processes and materials
are strong drivers behind the development of
efficient lightweight construction solutions
and their implementation in series production,
such as energy-saving components for chassis,
engine and gearbox.
The EAC congress ‘Aluminium Automotive
Applications’ is divided into a total of
five sessions, dealing with the subjects design,
body structure, subframes, process technologies,
joining technologies and surfaces as well
as markets, recycling and sustainability. Notable
speakers from international companies
will offer information and real-life examples
in all the sessions of the congress.
Conference language is English. All presentations
will be simultaneously translated into
German. More information on the congress

ICEB – Intl Conference on Extrusion and Benchmark, 8-9 October 2013
The International Conference on Extrusion
and Benchmark (ICEB) has become
the biggest event in Europe related to
the recent developments on extrusion
technologies and their analysis by FEM
simulation. The fourth edition is planned
for 8-9 October 2013 in Dortmund, Germany.
More than 150 delegates attended the
2011 edition, with participants from over
27 countries including America and the Far
East. With two-thirds of the participants
coming from the industry and with representatives
from all the multinationals of
aluminium, a strong interest was evidenced
in getting and sharing knowledge on these
topics of technological frontier. The aim of
the conference is to join together technical
and scientific experts, to widespread their
knowledge and to form an international
community for the discussion of state of
the art, as well as future developments, in
the field of extrusion and in its most powerful
tool, the numerical simulation.
ICEB is a two-in-one event, merging a conference
on the ‘Latest advances in the extrusion
of light alloys’ with an industrial worldwide
contest: ‘FEM codes Benchmark’.
• In the conference sessions invited papers
from academia as well as from industries will
describe the most recent developments in the
analysis, optimisation and research of the light
alloys extrusion processing.
• In the benchmark sessions, participants
will be asked to simulate the extrusion of an
industrial case (a specially designed die for
emphasising selected process-related issues),
on the base of die geometries, material properties,
ram speed and tools temperatures, as
they were monitored by the organisers. Only
during the conference the blind simulations
results will be discussed and compared to
the data recorded during experimental trials,
thus allowing a clear and equal comparison
of different FEM codes and simulating approaches.
This two-in-one event provides a unique
opportunity to:
• learn about innovation and simulation
capabilities in the extrusion of light alloys
• get guidelines for best process analysis
and product optimisation
• understand the potential of your current
simulation tool
• have the widest possible range of information
on extrusion simulation today.
The conference heads toward extruders
(technicians, R&D divisions, production
managers), extruded profile users, academic
and industrial researchers, die makers,
alloys specialists, software houses and software
distributors, press and equipment builders.

Metef 2014 aiming to add new
field of excellence to Italy’s three Fs
The Metef trade fair, one of the leading
international events for aluminium and
innovative metals, will be held for the
tenth time from 11 to 13 June 2014 at
the Verona Exhibition Centre in Italy.
It will have a new format: it will be accompanied
by Foundeq and Metalriciclo-
Recomat as in previous years but will
include the new Alumotive fair for the
first time.
Advertisement
The whole production chain for innovative materials
will be presented at Metef 2014: from
primary and secondary production through
to the processing, machining and finishing of
extrusions, castings and rolled products, including
surface treatment. The new addition
is expected to meet its ambitious target of covering
the whole production chain for aluminium
in the transport and transportation sector.
The organisers are hoping 2014 will be a
turning point for Metef. In 2012, Alfin-Edimet
signed a strategic agreement with Veronafiere
that saw Veronafiere acquire a 50% share in
a newly formed company that took over the
assets of Alfin-Edimet. This partnership gave
Metef Foundeq 2012 a global dimension
thanks to the presence of over 500 exhibitors
from 29 countries and of 15,000 visitors, nearly
a third from 69 foreign countries. “The 2014
edition will represent the whole Italian aluminium
and innovative material production chain
on the international arena, where competitiveness
is more and more challenging,” said Veronafiere’s
president Ettore Riello at a recent
press conference. “Veronafiere then becomes
a guide for the organisational management of
this exhibition in order to consolidate Metef as
b2b show and to represent the whole Italian
manufacturing sector,” he added.
Italy is world renowned for its three Fs:
fashion, food and furniture. Metef 2014 is
aiming to add a new field of excellence: a customised
facility for the aluminium and innovative
metals technologies that represent the
core of the country’s manufacturing industry.
This has enabled Italy to develop the design
and manufacturing skills needed to produce
high-value products and tailored solutions.
Mario Bertoli, president of Alfin-Edimet,
stressed that the market had changed; globalisation
has altered where many goods are now
being produced and consumed, including in
the metals sector, but he said that this had
not affected Italian excellence. Customised
plants, machinery and technologies are still
Italy’s key strengths; they are well known and
highly regarded all over the world. He added
that Metef has been a major source of sector
growth over the last decade and more than
ever now provides a great opportunity for the
whole production chain to present itself internationally.
Metalriciclo-Recomat focuses on
recycling of industrial materials
Metalriciclo-Recomat will again deal with the
recovery and recycling of industrial materials
and will be offering specialist information on
products, machinery and technologies in this
sector. The show will benefit from Metef’s internationality
and Veronafiere’s global organisation
and contacts.
Despite the overall decline in the consumption
and production of secondary materials in
Aluminium China 2013, Asia’s leading aluminium
exhibition, looks back on a record breaking
number of visitors from around the globe at the
Shanghai New International Expo Centre in July.
With 462 exhibitors (121 first-time participants)
from China, Asia and further abroad, the exhibition
attracted more than 15,200 visitors, an
increase of 28% over last year. This development
in number of visitors reflects the rich potential
of Asia’s aluminium markets today driven by a
large number of exhibiting industry giants at
the show such as Kobe Steel, Shanghai Jieru,
Novelis, Wagstaff, Qatalum and SMS Group, to
mention just a few.
Aluminium China 2013 also presented two
new feature areas: semi-finished products for
transportation and other key industries, and
packaging products supported by the EAFA’s
Alufoil Trophy Award. Alongside the new
Italy in recent years, the quantity of recovered
and recycled materials is still high. The growth
in metals and materials recycling in all sectors
has led to a significant development of
machinery, systems and technologies made
in Italy for the recovery and recycling of materials.
Metef offers the industry’s players an
opportunity to present themselves internationally
and open up new business opportunities.
The Metalriciclo-Recomat fair is aimed at
car breakers, metal collection and recovery
companies, scrap users for downstream hot
processing, waste disposers, recycled metal
traders as well as authorities, associations and
institutions involved in the recycling sector.
Alumotive at Metef for first time
The Alumotive exhibition will present innovative
solutions, components and technological
materials for original equipment in the transportation
sector and will be part of Metef for
the first time in 2014. The show will promote
a sector that in terms of products and number
of employees is one of the traditional strengths
of the manufacturing industry in Italy. It will
be a welcome and useful addition to Metef.
Companies engaged as second and third
tier suppliers will constitute the largest sector
at Alumotive; their fields of activity include
innovative materials, design and production
of components, processing systems, robots,
engineering, mould making, machining and
finishing.
■
Aluminium China 2013 celebrates record attendance
feature areas, the show also launched the Aluminium
Downstream Processing Forum, where
the audience gained insights into latest developments
across closely related application sectors.
The EAFA’s display zone was also combined with
a forum on future opportunities for aluminium
packaging applications in China.

WIRTSCHAFT
„Metalle pro Klima“-Veranstaltung bei Otto Fuchs
Klimaschutz durch energieeffiziente Produktion
Die zwölfte Regionalveranstaltung der
Unternehmensinitiative „Metalle pro Klima“
fand Anfang Juli bei der Otto Fuchs
KG in Meinerzhagen statt. Hinrich Mählmann,
persönlich haftender Gesellschafter
des Unternehmens, betonte den Beitrag
der Industrie für den Klimaschutz.
„Wir reduzieren unsere CO 2 -Emissionen
durch Energieeffizienz in der industriellen
Produktion in beträchtlichem Umfang
und kontinuierliche Innovationen und Investitionen“,
erklärte er. Welchen Beitrag
Otto Fuchs zu Klimaschutz, Energie- und
Ressourceneffizienz beiträgt, unterstrich
das Unternehmen mit mehreren Best-
Practice-Beispielen. Der Hersteller von
Produkten aus Aluminium, Titan, Magnesium,
Nickel und Kupfer für die Luft- und
Raumfahrt, Automobil- und Bauindustrie
ist Mitglied der Initiative der NE-Metallindustrie.
Draufsicht der beiden neu installierten Zweikammer-Schmelzöfen
Das traditionsreiche Familienunternehmen
aus dem Sauerland hat in den zurückliegenden
zehn Jahren an den deutschen Standorten
mehr als 300 Millionen Euro investiert. Allein
im laufenden Jahr werden 40 Millionen Euro
für den Standort in Meinerzhagen aufgebracht.
Investitionen in energieeffiziente Maßnahmen
haben daran einen erheblichen Anteil. Mählmann
sprach seine Erwartungen an die Politik
deutlich aus: „Wir setzen auf gute und verlässliche
Rahmenbedingungen für die Industrie in
der Energie- und Steuerpolitik. Dazu gehört
auch der Ausbau und der Erhalt einer modernen,
flächendeckenden Infrastruktur für das
Industrieland Deutschland.“
Martin Kneer, Hauptgeschäftsführer der
WirtschaftsVereinigung Metalle (WVM), unterstrich
auf der Veranstaltung: “Die Grundstoffindustrie
ist ein wesentlicher Faktor in
der Wertschöpfungskette und legt die Grundlagen
für ein stabiles Bruttosozialprodukt, das
wir mehr denn je benötigen. Unser Ziel ist es,
mittels Best-Practice-Beispielen aus der industriellen
Produktion einen offenen Dialog mit
Politik, Wirtschaft und Medien zu führen.“
Im direkten Gespräch mit Abgeordneten
aus Bundes- und Landtag, Kommunalpolitikern
sowie zahlreichen Personen aus dem
öffentlichen Leben der Region stellten die
Experten der Otto Fuchs KG ihre Beiträge
zu Klimaschutz, Energie- und Ressourceneffizienz
vor. Die Politiker, darunter der Wirtschaftsexperte
Matthias Heider sowie die Sozialpolitiker
Johannes Vogel und Petra Crone,
sprachen einmütig ihre Unterstützung für den
Metallverarbeiter am Standort Meinerzhagen
aus. Sie zeigten sich beeindruckt von den umgesetzten
Maßnahmen zur klimaschonenden
und energieeffizienten Verarbeitung von
Metallen. Die Botschaft, dass Energie sicher,
sauber und bezahlbar sein müsse, sei angekommen.
Kneer und Mählmann forderten mehr Akzeptanz
in Gesellschaft und Politik für die Belange
der Industrie ein. „Schließlich hat uns
die Realwirtschaft durch die Krise geführt. Das
sollte von einem Mentalitätswechsel begleitet
werden, der letztlich zu ausbalancierten politischen
Entscheidungen führt“, betonten sie.
Optimierte Schmelztechnik erhöht
Materialeffizienz bei Otto Fuchs
„Metall wird bei der Otto Fuchs KG direkt
zurück in den Produktionskreislauf geführt.
„Dies ist für uns sowohl
ökologisch als auch
ökonomisch sinnvoll“,
erklärte Gießereileiter
Frank Vieweg bei der
Vorstellung von Best-
Practice-Beispielen zur
Ressourceneffizienz
und zum Klimaschutz.
Die Stranggießerei des
Unternehmens verarbeitet
fast das gesamte
Kreislaufmaterial, das
in der Produktion im
Werk Meinerzhagen
anfällt. In insgesamt
acht Induktions- und
drei gasbeheizten
Schmelzöfen wird das Material getrennt nach
Legierungen erschmolzen und im Strangguss
zu Rundbarren vergossen.
Im Jahr 2010 wurden vier elektrisch beheizte
Induktionsschmelzöfen nach 40 Jahren
Betrieb durch zwei gasbeheizte Zweikammer-
Schmelzöfen neuester Bauart ersetzt. Dies
spare jährlich rund 6.000 Tonnen CO 2 direkt
auf der Energieseite von Otto Fuchs plus etwa
3.000 Tonnen CO 2 indirekt durch die Erhöhung
der Metallproduktion ein, hob Vieweg
hervor.
Die besonderen Merkmale des Zweikammer-Schmelzofens
liegen in der betont energiesparenden
Schmelztechnik, die auch die
am Einsatzmaterial anhaftenden organischen
Bestandteile als Energieträger nutzt. Gleichzeitig
werden hohe Schmelzleistungen bei
flexibler Schrottart und -qualität erreicht.
Die eingesetzten Öfen arbeiten nach folgendem
Prinzip: Zunächst wird das einzuschmelzende
Material in die Chargierkam-
Steuerzentrale (links) und Wärmerückgewinnungseinheit mit Rauchgaskamin (rechts)

mer des Ofens gefüllt, dort vorgewärmt und
getrocknet. Nachdem die Kammer mit dem
Rücklaufmaterial befüllt wurde, wird bereits
flüssiges Metall von der Hauptkammer
in die Chargierkammer gepumpt. Der Füllstand
steigt an und das Einsatzmaterial wird
geschmolzen. Gleichzeitig werden die beim
Vorwärmen entstehenden energiehaltigen
Schwelgase (am Rücklaufmaterial anhaftende
Schmierstoffe) in die Hauptkammer geführt
und dort als Energieträger genutzt. Anschließend
wird die Aluminiumschmelze in einem
optimierten Übergabeprozess in den Gießofen
überführt und vergossen.
Der Energiebedarf für das Recycling der
Aluminiumlegierungen liegt
mit rund 600 kWh/t bei nur
etwa fünf Prozent des Energiebedarfes,
der zur Herstellung
von Hüttenaluminium notwendig
ist. Außerdem ist der
Logistikaufwand durch Transporte
beim werksinternen Recycling
vergleichsweise gering.
„Beides wirkt positiv auf den
Klimaschutz, da große Mengen
an CO 2 eingespart werden“, so
Vieweg. Durchschnittlich fünf
Lkw-Fahrten je Woche zum
Transport des Rücklaufmaterials
werden so vermieden.
Recycling ist in Deutschland
mit etwa zwei Dritteln
des erzeugten Materials eine
der wesentlichen Rohstoffquellen für die heimische
Industrie. Die Gießerei von Otto Fuchs
bezieht vier Fünftel des eingesetzten Aluminiums
aus Rücklaufmaterialien des internen
Fertigungsprozesses. Das „Inhouse“-Recycling
von Überschüssen aus der Produktion –
Grate, Pressreste oder Späne – generiert neben
den positiven Auswirkungen auf den
Klimaschutz auch erhebliche wirtschaftliche
Vorteile wie Absicherung der Vormaterialversorgung,
Erhöhung der Flexibilität oder
Senkung der Logistikkosten.
Energieschonende Metallverarbeitung
durch Wärmerückgewinnung
Das Wärmerückgewinnungssystem im Stammwerk
ist ein weiteres Beispiel für die Steigerung
der Energie- und Ressourceneffizienz.
„Mit Hilfe der Wärmerückgewinnung aus
Rauchgas konnten wir seit September 2010
über vier Millionen Kilowattstunden Energie
einsparen und den Ausstoß um 985 Tonnen
Kohlendioxid verringern“, erläuterte Harald
Dewinklo, Prokurist und Leiter Einkauf bei
Otto Fuchs.
Schmiedeprozess von Alu-Rädern
Bei dem neuen, in Zusammenarbeit mit der
ONI Wärmetrafo GmbH aus Lindlar entwickelten
Verfahren wird das bis zu 900 °C
heiße Rauchgas über einen frequenzgeregelten
Heißluftventilator aus dem bestehenden
Kamin angesaugt und über einen Wärmetauscher
geleitet. Die zurückgewonnene Wärme
wird für die Warmwasserbereitung genutzt.
Dadurch wird das Kesselhaus entlastet und
Nutzenergie unabhängig von diesem bereitgestellt.
„Die Rückgewinnung thermischer Energie
minimiert den Primärenergieverbrauch,
reduziert überflüssige CO 2 -Emissionen und
erfüllt energiewirtschaftliche und ökologische
Ziele“, betonte Dewinklo.
Die als Baukastensystem entwickelte Lösung
kann als Grundkonzept für Betriebe mit vergleichbaren
Öfen und Warmwasserbetriebsnetzen
genutzt werden. Der flexible Aufbau
mit Regelkomponenten an den einzelnen Bausteinen
ist beliebig kombinierbar.
Schmiederäder aus Aluminium
für klimaschonende Mobilität
Die Begrenzung des CO 2 -Ausstoßes von Pkw
ist für eine klimaschonende Mobilität nicht
nur ein europäisches, sondern zunehmend
auch globales Thema. Der Kraftstoffverbrauch
von Pkw ist von zahlreichen Faktoren abhängig,
vor allem aber vom Gewicht: 36 Prozent
des Kraftstoffverbrauchs ist gewichtsbedingt.
Leichtbau trägt daher entscheidend dazu bei,
einen geringeren Verbrauch bzw. eine höhere
Nutzlast bei Fahrzeugen zu erreichen und damit
auch die Abgasbelastung zu reduzieren.
„Schmiederäder aus Aluminium sind ein
beliebtes Designelement an Fahrzeugen und
leisten besonders bei großen Radabmessungen
einen signifikanten Beitrag zur Gewichtseinsparung
und damit zur Minimierung der CO 2 -
Emissionen“, beschreibt Bernd Velten, Leiter
Technischer Vertrieb und Marketing bei Otto
Fuchs das verbindende Element von Mobilität,
Design und Klimaschutz.
Der Gewichtsvorteil eines Schmiederades
liegt bei etwa 15 Prozent gegenüber einem
Gussrad (durchschnittliches Gewicht ca. 11
kg), was zu einem Gewichtsunterschied von
netto 1,65 Kilogramm führt. Das bedeutet
eine Emissionsreduzierung von circa 0,165
Gramm CO 2 je Rad und Kilometer Fahrleistung.
Die Einsparung setzt sich aus zwei
Teilen zusammen, jeweils im Vergleich zu
gegossenen Alu-Rädern: zum einen aus der
direkten Verbrauchsminderung infolge der
Gewichtseinsparung, zum anderen
aus der Einsparung an
Primärenergie zur Erzeugung
von Hüttenaluminium. Für
das auf die Herstellung geschmiedeter
Alu-Räder spezialisierte
Unternehmen Otto
Fuchs – Fertigungsvolumen
jährlich 1,6 Mio. Räder – errechnet
sich bei einer durchschnittlichen
Fahrleistung von
15.000 Jahreskilometern eine
direkte Einsparung von jährlich
4.000 Tonnen CO 2 plus
weiteren 24.000 Tonnen CO 2
dadurch, dass 2.600 Tonnen
weniger Hüttenaluminium benötigt
werden.
In den 1960er Jahren erfand
Otto Fuchs die Kombination von sogenannten
Gesenkschmieden und Fließdrücken als
wesentliche Voraussetzung für die Fertigung
einteiliger Schmiederäder. Bis heute ist diese
Technologie das technische Alleinstellungsmerkmal
von Otto Fuchs im hart umkämpften
Markt der Pkw-Räder aus Aluminium.
Die Technologie der Schmiederadherstellung
baut auf jahrzehntelangen Erfahrungen
auf. Im Zuge der politisch und öffentlich gewollten
Gewichtsreduzierung bei der PKW-
Herstellung werden ihre Möglichkeiten deutlich
höher bewertet. Ganz besonders gilt dies
für innovative Fahrzeuge mit Elektroantrieb,
denn die Reichweitenproblematik erfordert
maximale Anstrengungen bei der Gewichtseinsparung.
Außerdem erlauben Schmiederäder
die Herstellung aerodynamisch günstiger
und trotzdem leichter Räder und senken somit
im doppelten Sinne den Fahrwiderstand.

Practice-Beispiele zu weiteren Anwendungen
von NE-Metallen wie Aluminium,
Kupfer, Zink finden sich auf dem Internetportal

The SMS group had to face a significant decline
in orders intake in 2012 of about 17
percent to 2.8 billion euros. However, sales
increased by five percent to 3.2 billion euros,
and the net group result of 258 million
euros was almost matching the previous
year’s level. At the company’s annual press
conference, Heinrich Weiss, chairman and
chief executive of the SMS group, stated
that both business areas, SMS Siemag and
SMS Meer, had clearly felt the impact of
customers’ restraint in placing orders.

Heinrich Weiss, seit 45 Jahren für den Aufbau
und die Führung der SMS group verantwortlich,
hat sein Mandat in der Geschäftsführung zum 1.
Juli 2013 niedergelegt und den Vorsitz im Aufsichtsrat
übernommen. Der bisherige Vorsitzende,
Manfred Bischoff, wird dem Unternehmen als
AR-Mitglied verbunden bleiben. Joachim Schönbeck,
bisher bereits Mitglied der Geschäftsführung,
wurde zum Sprecher des Unternehmens ernannt.
Gemeinsam mit seinen Kollegen Burkhard
Dahmen und Eckhard Schulte wird er weiterhin
die Geschäftsführung der SMS GmbH bilden.
Joachim Schönbeck wird wie bisher primär für
SMS Meer zuständig sein und Burkhard Dahmen
für SMS Siemag (inkl. der Mehrheitsbeteiligung
Paul Wurth). Eckhard Schulte ist Finanzchef der
Gruppe.

Heinrich Weiss, chairman of the supervisory board
of the SMS group since 1 July
With effect from 1 July, Heinrich Weiss, who has
been responsible for the development and leadership
of the group of companies for the last 45 years, has
resigned from his post on the managing board and
assumed the chairmanship of the supervisory board.
The present chairman, Manfred Bischoff, will retain
his commitment to the company as a member of
the supervisory board. Joachim Schönbeck, who is
already a member of the managing board, has been
appointed to represent the company externally with
effect from 1 July. Jointly with his colleagues, Burkhard
Dahmen and Eckhard Schulte, he will continue
to constitute the management of SMS GmbH. Mr
Schönbeck will be primarily responsible for SMS Meer
as before, Mr Dahmen will be responsible for SMS
Siemag (including the Paul Wurth majority holding)
and Mr Schulte will be the CFO of the group.

Looking ahead Mr Weiss, who resigned from
his post on the managing board on 1 July and
at the same time assumed the chairmanship of
the supervisory board, commented: “Despite
a persistent reluctance of our customers to invest,
we expect a slight recovery on the market
by the end of the year. Based on the continued
high level of orders in hand, and taking
into account the effects of the first full year
of consolidation of the Paul Wurth group this
year, we anticipate a modest increase in sales
compared to 2012, but a decline in profit.”
To ensure high quality, SMS remains committed
to producing the most complex components
of its machinery and plants in Germany.
That is why the company invested heavily over
recent years in expanding and upgrading its facilities
in Hilchenbach and Mönchengladbach.
Yet, parallel to these measures, it expanded its
production capacity in China. Here it is mainly
about better customer service on the ground
as well as special products designed for the
Chinese market and produced at a lower price
locally: in view of the aluminium extrusion
business this, for example, applies to mediumstandard
presses up to 35 MN.
Overall, the aim is to further cut manufacturing
costs by focusing on production­optimised
design, greater efficiency in logistics,
plus increased productivity in both engineering
and production. Using the same strategy as
that pursued in the years after the first financial
crisis, the company will make the most of
the weaker order intake to drive technological
development. Equally important to the management
is intensifying on­the­job training and
qualification of experienced core personnel as
well as training new staff.
SMS is also expanding its presence outside
Europe by hiring qualified personnel as well
as building production and service facilities in
the key markets China and India. “This is how
we will be able to meet demands in China for
a locally­produced share of supplies without
increasingly losing these types of orders to local
competitors,“ said Mr Weiss, adding that
there was still an increased demand for plants
for the aluminium industry in China.

infolge eines großen Nachholbedarfs die
Volksrepublik China nach wie vor der Wachstumstreiber.
Bei den hydraulischen Pressen

Moreover, SMS Siemag attracted two orders
for GATV strip flotation ovens for aluminium
strip processing plants – one order is, again,
from Henan Zhongfu while the other one is
from the Ma’aden Alcoa joint venture, where,
as from 2014, 50,000 tonnes of aluminium
strip a year will be annealed and chemically

impressive features of the GATV strip
flotation ovens in both lines are the compact
design, even strip heating and cooling over the

and eco­friendliness.
SMS Meer benefits from
backlog of demand
The exceptional boom in the aluminium industry
continued in 2012 and generated high demand,
particularly in China which remains the
engine of growth because of its huge backlog
of demand. For the hydraulic presses this led
to new dimensions in product sizes. Jilin Liyuan
Aluminium in Liaoyuan (Jilin Province)
ordered two new presses from SMS Meer: a
160­MN front­loading press and a 60­MN direct/indirect
tube press. The 160­MN machine
will be the world’s largest modern extrusion
press of its type in operation today. It will enable
Jilin Liyuan to manufacture profiles up
to one metre in width. The maximum profile
length is 28 metres – equivalent to the railcar
length of modern high­speed trains such as the
ICE or the TGV. With the new machine, Jilin
will be able to manufacture railcar components
in a single extrusion process. That saves
time, energy and money. Extra benefits are the
lightweight design and high recycling capability
that meet green requirements.
Ecomelt furnaces – high energy
efficiency and low metal loss
The melting of aluminium scrap has been gaining
in importance for years. Here Ecomelt
furnaces from Hertwich Engineering are in
demand as they consume much less gas than
conventional melting furnaces. The results are
lower energy costs, and the immersion melting
process reduces metal loss to below three
percent. Orders for the supply of Ecomelt
furnaces were placed by Novelis Italia, Impol
in Slovenia and Constellium in the Czech Republic.
Aluminij Mostar, Bosnia­Herzegovina, ordered
a belt­type billet casting line from Hertwich
to boost its productivity and flexibility.
The plant comprises a melting and casting furnace
as well as an air­cooled belt­type billet
casting line. Trimet Aluminium in Germany
commissioned a billet casting line in 2012; a
detailed description of the plant is given on
pages 44ff.
Hertwich received orders from the aluminium
producers Dubal and Emal for ultrasonic
testing facilities for the quality control of billets.
Furthermore, Emal awarded a contract
for the supply of two chamber homogenising
furnaces.

CRU’s World Aluminium Conference 2013 in London
Key turning points
Principal issues that have been affecting
the aluminium industry over the past
couple of years are reaching key turning
points. This sentiment was echoed by
a number of speakers at CRU’s World
Aluminium Conference in London this
year. Recurrent themes surrounding the
functionality of the LME and its warehouses,
legislative impacts on the industry
and understanding where the value is in
the supply chain were among the hotly
debated topics engaging the conference’s
250 delegates.
the LME – help or hindrance?
The primary aluminium market is currently in
a state of gross oversupply. It is estimated that
approximately five million tonnes of metal is
stored in LME warehouses, whilst consumers
are waiting for access to their metal due to excessively
long queuing times. The link between
LME warehouses, price premiums and the
continuous state of oversupply brought into
question the role of the LME in the industry.
The consensus was that the situation is now
critical and needs to be addressed by major
players in the market to restore balance.
One of the key­note speakers, Oleg Mukhamedshin,
deputy CEO at UC Rusal, called
for greater transparency in LME pricing
mechanisms and a push for these prices to
greater reflect actual market fundamentals. A
question repeatedly raised by delegates was
why aluminium smelters were still producing
at historically high rates despite depressed
prices and an already plentiful stockpile in
warehouses. In addition to this, estimates that
20 to 30% of all producers (excluding China)
were making a loss at today’s price levels
fuelled further questions surrounding producer
responsibility and controls on production.
Tim Reyes, president of Alcoa Minerals
Management, explained that the influence of
the financial community on the LME pricing
system was unlikely to change in the nearterm.
He believes that capital will continue
to flow through the industry, and that people
will be keen to hold onto their assets. Instead
of waiting for a turn in the financial markets,
the industry must look towards producers for
swift implementation of curtailments. Alcoa,
for example, are advancing their programme
to curtail capacity, with over 560,000 tonnes
of primary aluminium shutdown in 2012, and
plans to review additional curtailments over
the coming months. Other major producers including
Rusal are thought to be implementing
similar strategies to counter market surplus.
In this context, CRU believes that if prices
fall a further 5 to 10% below current levels,
it could have a significant impact on the volume
of curtailments. The mutual dependence
of the power as well as aluminium industry
as one of the drivers behind escalating warehouse
stocks is an alternative view on the situation.
With energy intensive industries such
as aluminium often providing an ideal outlet
for stranded power, an intimate relationship
has developed between the two. The result
has seen the power industry and governments
with surplus power dictating the construction
of aluminium smelters instead of the reverse.
In a market of significant surplus, consumers
should be the winners, benefitting from
the low prices associated with plentiful supply.
This, however, is not the case for most consumers
at present. The problem the consumer
faces in the current market is that LME warehouses
have made access to metal a difficult
and lengthy process. Not only are consumers
unable to hedge the premiums associated with
the metal, a large proportion of LME aluminium
is held at two main locations: Vlissingen
in The Netherlands and Detroit in the United
States. Despite new legislation designed to
make access to the metal easier, long queues
persist at these locations.
Will China deliver?
Another potential solution to the market surplus
seen today would be the realisation of
the long predicted ‘China effect’ taking hold of
the aluminium industry. For a number of
years, China has been singled out as a key contributor
to booming commodity markets, fuelling
unprecedented growth in industries such
as iron ore. The aluminium industry had, until
recently, been predicting similar increases in
demand and a drawdown of primary metal
to supplement domestic supply gaps. These
predictions have yet to materialise and it is
seemingly less likely that such significant supply
gaps with actually transpire.
CRU believes that while government policies
will favour the import of energy intensive
products such as aluminium, the current high
primary production levels and widespread
overcapacity leaves little scope for China to
increase imports. Despite this, there is some
hope that activity in China may provide some
support in restoring balance to the primary
aluminium market.
China’s recently elected government has
proposed four main options to deal with overcapacity:
increasing demand for primary aluminium,
moving capacity to other countries,
encouraging greater industry consolidation
and closure of old, outdated capacity. By far
the least explored option, moving capacity,
has seen an increase in recent activity with
Rusal and Chalco signing an MoU to build
a Siberian smelter, following in the footsteps
of Rusal, China Xinfa Group and China’s
Citic who have also made steps to establish
themselves abroad. Whilst there is indication
of development in all of the aforementioned
options, the collective impact may do little
to the overall balance if China pushes ahead
with new smelter capacity in Xinjiang.
the raw materials challenge
China will need to look for alternative supply
for their booming smelter and refinery industry,
especially with the Indonesian export ban
anticipated in 2014. With further evidence
of a push towards resource nationalism from
a number of countries, securing future feedstock
supply will be a key challenge not only
for China, but for primary producers across
the globe. Since the Indonesian government
made clear their intention to restrict raw
material exports back in 2009, resource nationalism
has become a central theme of the
upstream aluminium industry.
An Indonesian ban on bauxite exports is
anticipated to heavily impact China as Indonesia
is the country’s largest supplier of gibbsite
bauxite. It is likely that traditional Chinese
importers will look to secure resources
by investing in refining facilities in Indonesia.
In addition to the much­discussed Indonesian
bauxite ban, numerous other policies were
touched upon in key producing regions: MRRT
and carbon tax in Australia, bauxite export
bans in India, an export ban in Vietnam and
reviews for the royalty system in Brazil. The
push for these policies will greatly impact the
security of bauxite supply for producers and
led some to question if bauxite would become
the new iron ore.
The consensus amongst the panel for the
Raw Materials and Cost Trends Session was
that while there are some issues surrounding
access to bauxite and difficulty in bringing
projects on­line, the world’s bauxite resource
base is plentiful. Therefore, whilst prices are
expected to increase, the consensus is that it is
22 ALUMINIUM · 7-8/2013

unlikely to reach the levels that iron ore has.
Where is the value?
There was agreement that value is diverging,
with a movement upstream towards bauxite
and downstream towards rolled products.
The challenging environment developing
at the upper end of the value chain has contributed
to the shift in profitability. As supply
of feedstock tightens and sources become
less clear, prices are expected to rise and
lesser known bauxite producing countries
will emerge as front runners of supply. It is
thought that this uncertainty in the upstream
industry could potentially be the production
constraint that the industry needs to curtail
primary production.
At the other end of the spectrum, the rolled
products market is benefitting from a surge in
demand driven by the transport and construction
sectors. Investments into research and
development for aluminium uses have been
prolific in recent years, and with the automotive
and aerospace industries in particular
realising the benefits of aluminium, there is
scope for significant growth. Low primary
prices have benefitted the downstream industry
and increased the competitiveness of
aluminium as a substitute for other materials
in transport sector.
Aluminium is able to provide automotive
manufacturers with significant weight
reductions and therefore better fuel savings
and lower emissions. For every 10% saving
in weight, a 5 to 7% saving can be made on
fuel. This has a number of beneficial knock­on
effects for: (a) the consumer as cars require
less fuel, (b) the producer as weight saving improves
performance and (c) the environment
as automotive emissions are reduced.
the demand for sustainability
With respect to ‘recycling’, there was agreement
that legislation would, in time, need to
be revised to better represent the changes in
consumer usage today. Scrap was identified as
a major opportunity for Europe to retain aluminium
production while primary producers
suffer with tougher operating environments.
The demand for specialised alloys from secondary
material is also growing strongly, driven
primarily by the automotive sector.
Europe has the opportunity to capitalise on
this growth to ensure that it is not merely a
scrap exporter, but that it is following in the
footsteps of other regions and ensuring that
value is being added to resources before
export. In this case, Europe’s resource is its
significant scrap pool, which, under current
forecast consumption rates will continue to be
a major source of aluminium for many years
to come.
Growing importance of sustainability within
the industry is demonstrated by Novelis
Europe with an ambitious target for 80% of
their material to be from recycled products
by 2020.
What does the future hold
for the aluminium industry?
The outlook for aluminium, according to many
industry experts, remains dependent on the
actions of the LME. Tackling the issues surrounding
premiums and warehousing are integral
to improving the current imbalance in
the market. Others believe much of the
blame lies with producers who continue to
ignore ‘free market commercial signals’ that
call for greater control and curtailment in
production. In reality, it is perhaps the responsibility
of both the aluminium producers and
the LME to take active steps towards a resolution.
Producers must cut high cost capacity
and ensure that capacity is built in response
to demand instead of other industry factors.
Meanwhile the LME, facilitators of the current
surplus market, must look for a way to reduce
the influence of the financial community on
the LME price, and instead adopt a pricing
mechanism that better represents the fundamentals
of the market. The most recent commitments
by companies to curtail production
will steadily reduce surplus, and this, paired
with strengthening demand across the value
chain, provides potential respite for the situation.
Aluminium, unlike a number of other metal
markets, has never seen the commodities supercycle
reflected in its pricing. The boom in
commodities prices, partially fuelled by China,
had significant impacts on the iron ore and
copper markets but the fundamentals of the
aluminium market have worked against such
significant price escalation. With the easing of
Chinese growth, sentiment in such China­centric
markets has suffered, and now the lack of
a supercycle in the aluminium industry can be
viewed as a benefit.
Over the next few years, as other industries
struggle with changes in market factors that
are essentially out of their hands, aluminium
is in a stronger position to make the necessary
changes from within the industry itself.

New alumina project approach –
dedicated design, compact capacity
P.-h. ter Weer, tWS Services & Advice
1. Synopsis
As discussed elsewhere the design / initial refinery
production capacity of greenfield alumina
projects outside China has evolved from
about 0.5­1.0m tpy 25 to 30 years ago to about
1.5­3 + m tpy for more recently constructed and
future planned projects [1]. Despite this large
scale increase economics did not structurally
improve, mainly as a result of large capital cost
increases for alumina projects in this period.
The increase in project scale had major consequences:
• Significantly increased project complexity:
planning and management, extensive government
involvement, huge capital cost (multibillion
USD, project financing, multi­party joint
ventures).
• Worldwide only a limited number of large
companies are left with the resources to develop
greenfield projects, and only a few engineering
firms with the skills and experience
to implement these projects.
• Typically a project life of 30 + years applies
to the significant investment of a greenfield
bauxite and alumina project. For projects with
a captive refinery this means that the bauxite
deposit on which they are based should sustain
refining operations for such a period of time.
Therefore only (very) large bauxite deposits
are developed, indicatively 200­300 million
tonnes and more.
• Summarising: worldwide only a small num­
ber of companies develop mostly very large
greenfield bauxite and alumina projects which
often takes a decade or more.
This paper describes a new two­stage approach
to improve on the state of affairs
outlined above: first and foremost base any
greenfield project on a dedicated design and
layout for a specified production capacity, and
secondly apply this methodology to a compact
refinery capacity. Objectives are to improve
alumina project economics and to develop
an option of smaller greenfield bauxite and
alumina projects at acceptable economics.
The economic basis of the new approach is
discussed in section 3, technical aspects are
covered in section 4.
2. Commodities and
current refinery design
Commodities such as concrete, steel, mechanical
bulks (e.g. valves), piping, wire and cable,
etc. represent a significant element (typically
~30%) of a refinery’s capital cost as illustrated
in the left­hand column (Current design) of
Table 1 (see next page) for a typical currentdesign
1.5m tpy ‘low­temperature digestion’
alumina refinery.
Importantly commodity amounts and the
related capital costs reflect plant design and
layout. Current alumina refineries are designed
to accommodate additional future digestion
units (and all of the other required process
units – e.g. precipitation, evaporation), i.e.
plant design is not optimised for its initial production
capacity. Plant layout is characterised
by an ‘open architecture’ as illustrated in Fig.
1 by the main piperack layout of recently
designed 1.5m tpy alumina refineries, which
represents at best a compromise between the
limited layout requirements for the initial /
design capacity and the more extensive requirements
to accommodate future additional
process units. And at worst consists of a largecapacity
plant part of which is built, resulting
in an inefficient plant layout for the design /
initial capacity. In summary plant design is
not optimised for its design / initial production
capacity.
3. New project approach
3.1 Step 1 – Dedicated design & layout
The new approach is based on a dedicated
refinery design and layout for a specified production
capacity, i.e. tailoring the design to the
equipment and infrastructure requirements
(earth works, power, water supply, piperacks,
roads, cable trays) of the selected production
capacity. This approach enables optimising
plant layout for the targeted production capacity
e.g. with respect to positioning similar
equipment close to each other, and the use of
common spares; it impacts positively on commodity
volumes, and it focuses on a ‘lean’
design. Consequentially the design excludes
provisions for future expansions, which should
be justified on their own economic merits.
This more ‘closed’ layout architecture results
in a more efficient plant layout, reflected for
example in the design of the main plant piperacks
as illustrated in Fig. 2 for a 1.5m tpy
refinery (compare with the piperack layouts
of Fig. 1 which are on the same scale).
This new approach impacts positively on
commodity volumes (refer to [2] for details):
for the same production capacity commodity
volumes for steel, concrete, piping, etc. for a
greenfield plant designed along this approach
are similar to that of a brownfield expansion

of an existing refinery. In other words per
annual tA production capacity significantly
lower amounts of commodities are required
for greenfield projects based on this approach
compared with current, resulting in lower
costs. The effect on refinery capital cost is illustrated
in the right­hand column of Table
1 for a dedicated design 1.5m tpy ‘low­ temperature
digestion’ refinery: the capital cost
per annual tA capacity improves indicatively
by about 10%.
3.2 Step 2 – Compact production capacity
The second step of the new approach addresses
the issues of complexity and huge capital
cost of current alumina projects: by applying
the dedicated­capacity approach to a compact
refinery capacity of about 300,000 to 600,000
tpy the resulting project has a simple and limited
scope. The higher end of this range is limited
by the objective to end up with a total project
capital cost well below USD1bn (mega project
threshold); the lower end is determined
by logistical limitations (e.g. with respect to
raw materials shipping). As a result some indirect
capital cost items decrease more than
proportionately such as costs related to temporary
construction and start­up support, camp
and other construction related items, and

As illustration a production
capacity for a greenfield
400,000 tpy dedicated design
plant is used here, and its related
capital cost (indicative
numbers) is shown in Table 2.
Table 2 shows that the capital
cost per annual tA (1,347
USD/AnntA) is higher than that of the much
larger 1.5m tpy dedicated plant (1,014 USD/
AnntA – refer Table 1), however is at a level
which could result in a project with acceptable
economics provided infrastructure capital cost
is limited (refer [2] for further details). At the
same time a project based on a compact plant
capacity has very limited infrastructural requirements
and has several advantages over a
large plant, particularly if the project is located
close to an existing port, e.g. it may be allowed
closer to residential areas (i.e. is closer to existing
infrastructure); the existing infrastructure
may be sufficient for a small plant, but not
for a big plant; a suitable location for a small
residue disposal area is easier to find than for
a large one, etc. The table also shows that the
total capital cost is at a level which would enable
many more companies to develop such
a project without necessarily requiring the
formation of multi­party joint ventures, simplifying
overall project management and thus
enabling to decrease the capital cost further.
Note that the new approach is independent
of the selected refinery technologies.
4. 400,000 tpy capacity alumina refinery
The above outlined DCS approach (Dedicated
Compact Sustainable – this last aspect is not
discussed here) has been applied by modelling
a 400,000 tpy low­temperature digestion
refinery in a benchmark version of the Bayer
process (refer [3] for further details). The
steam temperature and pressure required for
low­temperature digestion enables first using
high pressure boiler steam for the co­generation
of power. This results in an energy and
capital efficient refining process.
4.1 Equipment sparing
• Key role for equipment cleaning / descaling.
• Substantial use of common spare equipment.
• If an outage would result in an immediate
alumina production loss, a spare or equipment
bypassing facilities are installed or extra capacity
in upstream / downstream equipment is
included. This also applies to frequently maintained
equipment.
• No sparing is included for the bauxite residue
washers and flash vessels which can be bypassed,
accepting transient process efficiency
reductions; a spare precipitator is installed and
the third precipitator in line can be used both
as agglomerating as well as growth precipitator.
• The refinery operates continuously, with
planned outages (accounted for in the overall
plant operating factor) being used to service
equipment. The sparing philosophy assumes
no scheduled extended total plant shutdowns.
• The sparing philosophy may require adjusting
to a specific plant location.
4.2 Plant design elements
• The digestion and liquor evaporation areas
positioned next to each other, enabling sharing
a common spare train of heat exchangers.
Advantages: equipment standardisation, simplified
operations and maintenance, less (types
of) spare parts.
• The bauxite residue discharging from the
CCD wash train contains less than ~8 g/l
caustic soda in the adhering liquor, enhancing
disposal options.
• The last two on­line precipitators operate
with agitators allowing varying slurry levels,
thus accommodating volume take­up when
descaling a tank.
• Precipitators are mechanically cleaned /
descaled. Main advantages: no major plant
volume / plant liquor caustic concentration
fluctuations, i.e. better control of both. Put
differently: tank cleaning and plant volume /
liquor concentration control have been separated.
Other advantages: no further spare precipitators
/ tanks of similar size are required
and steam savings (caustic cleaning).
• The filters for hydrate to calcination, for
fine seed to precipitation and for oxalate removal
are located in one building. Advantages:
equipment standardisation, operating procedures,
etc.
• A hydrate storage facility between precipitation
and calcination, enabling the Bayer
circuit to operate independently and as undisturbed
as possible from calcination. Two
calciners are installed, both normally in operation.
By uncoupling the Bayer circuit from
calcination, product quality control can be
optimised.
4.3 Layout considerations
The key advantage of the DCS design is that
the plant layout is optimised. This may be realised
in various ways, depending on bauxite
quality (boehmite, TOC, oxalate, etc.), select­

plant location specifics
(rainfall – water

philosophies.
The following layout
considerations are
based on the selected
refining process, design,
equipment sparing,
operating parameters
and equipment.
However most of these
would (fully or partly)
apply also if other choices are made.
• Position the digestion and liquor evaporation
areas next to each other (refer Fig. 3).
The causticiser feed heat exchanger is located
in the digestion / evaporation area because
evaporation export steam and digestion flash
condensate is used to heat the CCD­washer
overflow to causticisation. Attention should be
given to maintain the free caustic concentration
in the spent liquor through evaporation
at the hot end within acceptable levels.
• Place the bauxite residue settler and washers
in a horseshoe shape for easy access to
washer overflow standpipes and pumps, etc.
(refer Fig. 4). Lime related areas are positioned
next to each other (similar operating and
maintenance requirements) and close to the
washer train.
• Place the filters for hydrate to calcination,
fine seed for precipitation and oxalate removal,
as well as the cyclone classification areas
in one building (similar equipment, operating
and maintenance procedures, spare parts,
sharing of common spare tanks and pumps,
etc.) (refer Fig. 5).
• Position security filtration related equipment
close to each other for operating and
maintenance efficiency reasons; the heat interchange,
precipitation and interstage cooling
close to each other as these have many
interactions (minimising liquor / slurry pipeline
distances); and the main steam consumers
(digestion and evaporation) and the steam
and power plant close to each other to minimise
energy losses; and place if feasible the
bauxite crushing, grinding and pre­desilication
areas close to each other and to the digestion
area to minimise slurry pipeline distances.
• Construct in the centre of the plant a facility
accommodating the plant control room (including
control of the steam and power plant),
operations office and plant laboratory.
• Create good crane access to all major equipment
from 15 m wide plant roads, and if economically
justifiable consider pipe trenches
instead of piperacks for road crossings (ease
of access).
4.4 Overall plant layout
An overall process plant layout for a 400,000
tpy DCS plant is shown in Fig. 6, showing that
the new approach leads to a compact, simple
and efficient layout with a small Bayer loop,
illustrating that the goal to tailor the design
to the equipment and infrastructure requirements
of the specified production capacity is
achievable: most of the infrastructure is integrated
in the process areas and only limited
infrastructure is required outside those. ➝

5. Advantages of the new approach
The main advantages of the new approach
are:
• Reduced capital cost (lower risk) enabling
the development of bauxite and alumina
projects by smaller companies without a need
to form joint ventures, thus increasing the
number of companies potentially interested in
developing bauxite deposits. More competition,
more efficient use of (capital and bauxite)
resources.
• Small and simple projects carrying less risk
require less time to develop, construct and
start­up, positively impacting economics.
• Alumina refining projects based on this
approach require a small bauxite deposit (a
deposit of about 40m tonnes could support a
400,000 tpy project for 30 years), i.e. worldwide
the number of bauxite deposits lending
themselves to development increases, again
improving the use of resources.
• This new development model may also be
applied to the development of part(s) of a
large deposit.
• In some cases the new approach enables
value creation through alumina refining rather
than being limited to bauxite export (attrac­
tive to the host country and to companies developing
bauxite & alumina projects).
• An adapted version of the new development
model may in some cases enable bauxite
deposit development even in locations with
little existing infrastructure, albeit at a larger
than compact scale (see below).
6. Possible project locations
Examples of bauxite deposits that may lend
themselves to development via the proposed
approach are (between brackets the potential
alumina export port):
• Haden, Queensland, Australia (Brisbane)
• Bindoon, Western Australia (Fremantle)
• Central Northern Tasmania (Devon Port /
Bell Bay)
• El Palmar, Venezuela (Ciudad Guayana)
• Trelawny, Jamaica (Discovery Bay)
• Kibi, Ghana (Tema).
In addition some bauxite deposits which in
view of their large size could support the current
development approach with large­capacity
alumina refining projects, may also lend
themselves to stage­wise development applying
the new approach. In this case these deposits
could support several (smaller) greenfield
bauxite and alumina projects in an adapted
version of this new development model – e.g.
a dedicated 1.5m tpy capacity project. Example:
some of the Eastern Ghats deposits
in Orissa and Andhra Pradesh, India, e.g. the
Kutrumali deposit (with Visakhapatnam as potential
alumina export port).

Lage der Schweizer Aluminiumindustrie weiterhin angespannt
Die im Aluminium-Verband Schweiz zusammengeschlossenen
Unternehmen blicken überwiegend auf ein unbefriedigendes
Ergebnis 2012. Die Auswirkungen der Frankenstärke und der
Schuldenkrise in Europa belasteten den Geschäftsverlauf der
zu 80 Prozent exportorientierten Schweizer Aluminiumindustrie.
Dennoch konnten die Walz- und Presswerke ihre Gesamtproduktion
inklusive der Ausfuhren leicht um 0,4 Prozent auf
184.850 Tonnen gegenüber 2011 steigern. Im laufenden Jahr
zeigt sich die konjunkturelle Entwicklung weiter verhalten.
„Den moderaten Zuwachs von gesamthaft 0,4 Prozent inklusive der
Exporte 2012 gegenüber dem Vorjahr verdankt unsere Industrie vor
allem einer stark gesteigerten Produktion von Alu­Walzerzeugnissen
für den Transport­ und Automobilsektor. Dagegen mussten die
Presswerke Einbußen von bis zu 15 Prozent hinnehmen“, erklärte
Verbandsgeschäftsführer Marcel Menet.
Bei den Schweizer Leichtmetallgießern reduzierten sich die verarbeiteten
Mengen im vergangenenJahr auf 17.970 Tonnen (­14%).
Der Leichtmetall­Sandguss produzierte 2.740 Tonnen (­37%), der
Druckguss 12.770 Tonnen (­7%) und der Kokillenguss 2.460 Tonnen
(­10%). Der gesamte Aluminiumeinsatz im Inland ging um 0,6
Prozent auf 207.900 Tonnen zurück.
Auftragseingänge im ersten Quartal rückläufig
Die Krise hat sich nicht entschärft: „Auch bei den Auftragseingängen
im ersten Quartal 2013 verzeichnen die Pressprodukte ein Minus von
rund 13 Prozent“, gab Menet an. Verantwortlich dafür sind in erster
Linie der weiterhin starke Franken, der auch 2012 die Margen erodieren
ließ, sowie ausbleibende Bestelleingänge, verursacht durch
die schlechte Wirtschaftslage in den europäischen Ländern. „Aufgrund
des tiefen Euros drängten zudem verstärkt ausländische Anbieter
in den Binnenmarkt. Dies führte zu einem enormen Preisdruck
und zu zusätzlichen Auftragsverlusten für unsere heimische Industrie“,
erläuterte Verbandspräsident Markus Tavernier die Situation.
Einbußen erlitt die Schweizer Aluminiumbranche vor allem durch
geringere Bestelleingänge seitens der Maschinen­ und Elektrotechnik
sowie des Textilmarktes. Diese Industriezweige reagierten vor allem
mit der Beschaffung einfacher, in großer Serie hergestellter Aluminium­Basisteile
im günstigeren Euroraum.
Dagegen zählte für die Kunden im Verpackungsbereich, im Bauwesen
und Energiesektor sowie in der Medizinaltechnik auch 2012
die gewohnt hohe Schweizer Qualität, Flexibilität und Servicebereitschaft
mehr als der Preisdruck. Hier verhielten sich die Auftragseingänge
nahezu konstant und auch im laufenden Jahr wird mit keinen
größeren Einbrüchen gerechnet.
Den größten Zuwachs bescherte erneut das Transportwesen. Dank
dem großen Knowhow und der ungebrochenen Investitionsbereitschaft
in neue Entwicklungen und Fertigungsanlagen konnte die
Schweizer Aluminiumindustrie 2012 Neuaufträge und Produktionssteigerungen
für den Flugzeug­ und Schiffsbau sowie für Schienenfahrzeuge,
Nutzfahrzeuge und Automobile erzielen: mit komplexen
Konstruktionen im Ultraleichtbau­Strukturguss zur Reduzierung des
Gewichts und des CO 2 ­Ausstoßes genauso wie mit Walzprodukten
und hochwertig anodisierten Aluminiumteilen.
„Durch aufwändige Produktentwicklungen, Qualität und Lieferzuverlässigkeit
sowie erweiterte Dienstleistungsangebote wie die
Gesamtablieferungen von Walz- und Pressprodukten in der Schweiz, in Tonnen
verlängerte Werkbank für unsere Kunden haben sich unsere Mitgliedsfirmen
eine Alleinstellung erarbeitet“, so Tavernier. Auch für 2013
zeichnen sich hier bereits jetzt die größten Steigerungsraten ab.
Das Motto „Klasse statt Masse“ bringt die Überlebensstrategien der
Schweizer Branche auf den Punkt: Um die Wettbewerbsfähigkeit zu
erhöhen, wird zunehmend die Serienherstellung standardisierter Bauteile
in eigens dafür gegründete Fabriken im Ausland verlagert. Zahlreiche
Mitgliedsfirmen investieren aber auch zweistellige Millionenbeträge
in ihre F&E­Abteilungen und spezialisierten Fertigungsstätten
an den Schweizer Standorten, wie Tavernier weiter ausführte. ■

ALUMINIUM SMELTING INDUSTRY
Primary aluminium industry during the first half of 2013, Part I
Rudolf P. Pawlek, Sierre
© Alcoa
This overview covers the events of the
primary aluminium industry during the
first half of 2013. Part I focuses on the
regions Africa, America, Oceania and
Europe while Part II, which will be published
in our next issue, will look at the
Middle East and Asia.
In January Alcoa announced it expects aluminium
demand to increase by 7% to 49.4m
tonnes in 2013, up 1 percentage point from
the 6% growth seen in 2012. The bump in
global demand will be bolstered by an 11%
expansion in demand from China, as well as
strong growth from Brazil (3%), Russia (1%)
and India (3%). The change in demand from
North America and Europe should remain
relatively similar to 2012, with North America
seeing a 4% increase in demand (equal to the
2012 growth figure) and European demand,
which fell by 2% in 2012, declining by just
1% year-on-year in 2013. As a result of the
expected demand growth, Alcoa is projecting
a 200,000-tonne alumina deficit and a
535,000-tonne aluminium surplus in 2013.
Given the size of these markets, however, the
figures show that supply and demand are essentially
balanced. Alcoa also predicts a recovery
in LME prices, linked more to the global
economic situation than to market fundamentals.
Chinese output will reach 23.35m tonnes,
while its demand will be 23m tonnes, leaving
a small surplus which has grown from 100,000
tonnes in 2012. In the rest of the world, production
of primary aluminium output will be
26.61m, with demand forecast to be 26.42m
tonnes.
In May Alcoa announced that it will review
460,000 tpy of smelting capacity over
the next 15 months for possible curtailment
to secure the company’s competitiveness, as
aluminium prices have fallen more than a third
since their peak in 2011. Rusal and Chalco
have announced production cuts too. Rusal
will reduce primary aluminium production by
300,000 tonnes by year-end, and Chalco said
it would temporarily close 380.000 tpy of production
capacity.
AFRICA
Alcoa will close two Søderberg potlines at its Baie-Comeau smelter in Quebec
GUINEA: In March Russian aluminium giant
Rusal quietly abandoned plans for a multibillion-dollar
aluminium smelter in Guinea.
NIGERIA: In mid-March, the Alscon board
of directors decided to suspend aluminium
production at the plant. Previously, Rusal had
covered the plant’s losses, expecting to find
a sustainable gas supply which would enable
Alscon to operate at its full capacity. Despite
all measures undertaken by Rusal, Alscon does
not have a reliable and continuous gas supply.
Aluminium production at the plant is deeply
loss-making, which renders it impossible to
fully utilise the existing capacities. However,
Alscon will continue to generate electricity.
During the suspension period, the main ef-
forts of Rusal will be focused on securing continuous
gas delivery, obtaining judicial determination
that Rusal is the rightful owner of
Alscon, and preparing to restart operations.
Smelting will resume as soon as the legal uncertainty
has been resolved and the continuous
power supply has been secured.
In July Nigeria’s supreme court ruled that
former state-owned Alscon should have been
sold to a US-based firm, not to Rusal, but did
not question Rusal’s ownership. Rusal acquired
a 75% stake in Alscon in 2007 and now
owns 85% of its assets.
AMERICA
BRAZIL: In January Brazil announced it
would cut electricity costs by more than a
third across different sectors. Electricity tariffs
for industry, agriculture and retail would
be reduced by 32% while the reduction was
18% for residences. The cut is larger than the
16.2% for residences and 28% for industries
announced in September 2012. The impact of
the reductions will amount to an additional
expenditure of 8.46bn Reais (USD4.14bn).
The energy cost for Brazil’s aluminium industry
is 329 Reais per MWh (USD161/MWh)
on average, according to the industrial federation
of Rio de Janeiro. This is much higher
than China’s average electricity rate, equivalent
to 142 Reais per MWh (USD69/MWh).
Rates of 27 countries compared averages
about 215.5 Reais per MWh (USD105/MWh).
The country also plans to double its installed
capacity over the next 15 years from
the present 121,000 MW. Last year, about
4,000 MW and 2,700 kilometres of transmission
lines were installed. For 2013, the objective
is to install another 7,500 kilometres of
transmission lines and generate additional
8,500 MW of energy.
CANADA: In May Alcoa announced the
permanent closure of two older potlines at
its Baie-Comeau smelter in Quebec, and to
postpone the construction of a new potline by
three years as it looks to cut costs. The two
Søderberg potlines, which have a capacity of
105,000 tpy, are scheduled to be closed by
August. Restructuring charges related to the
closures are forecast to be USD135-155m
after tax in 2013. The potline closures come
after Alcoa announced to cut as much as
460,000 tpy of smelter capacity globally over
the next 15 months in the face of low alu-

because of current market conditions.
In addition, Alcoa would invest USD100m
in the Baie-Comeau smelter over the next
three years, with USD30m of that money earmarked
for upgrading the plant’s casthouse
operations as the company looks to support

That money comes in addition to USD75m
already scheduled to be spent to rebuild the
plant’s port facilities.
PARAGUAY: In May, it was reported
that Paraguay’s new elected president, Horacio
Cartes, is supportive of the USD4bn aluminium
smelter project planned by Rio Tinto,
which had been opposed by the previous
president Fernando Lugo.
The country is attractive for aluminium production,
due to its partnership with Brazil in
the Itaipu hydro-electric dam project – one of
the biggest in the world – and with Argentina
in the Yacyreta hydro-electric plant. Itaipu
alone provides 17.3% of all the energy consumed
in Brazil and 75.2% of that used by
Paraguay.

Certainly.
ABB’s history of powering primary aluminium plants started 45 years ago. Since
then, we have supplied complete electrification solutions and substations to more
than 60 aluminium smelters worldwide. The modernization of an existing plant to the
latest standards and production and efficiency levels – performed while it is still in
operation – requires a different set of skills and competencies than building a greenfield
plant. ABB has in-depth knowledge of the aluminium production process and

ergy it generates with its hydro-electric plants,
it sells the surplus to its Latin American partners.
USA: In April Century Aluminum announced
its Hawesville smelter in Kentucky
would close in mid-August if it cannot secure
competitively priced power. The 244,000 tpy
primary aluminium smelter has a power contract
with Big Rivers Electric Corp. The contract
expires on 20 August. Century remains
resolved to finding a solution that will support
the plant’s continuing operations, and is
in discussions with the power provider.
At the end of April, the company entered
into a definitive agreement to acquire substantially
all of the assets of the Sebree aluminium
smelter from Rio Tinto Alcan (RTA).
Sebree, located in Henderson County, Kentucky,
has production capacity of 205,000 tpy
of aluminium. Early in June Century completed
the transaction with RTA to acquire all
of the assets of the Sebree smelter. The transaction
is subject to certain closing conditions,
including the consent of Kenergy Corp. to the
assignment of the smelter’s existing power
contract, which will terminate on 31 January
2014.
In May Alcoa announced that it will review
460,000 tpy of smelting capacity over
the next 15 months for possible curtailment
to maintain the company’s competitiveness,
as aluminium prices have fallen more than
a third since their peak in 2011. The review
includes facilities across the Alcoa system,
and will focus on higher-cost plants and plants
that have long-term risk due to factors such
as energy costs or regulatory uncertainty. The
possible curtailments could affect 11% of Alcoa’s
global smelting capacity. Up to then, Alcoa
had 13%, or 568,000 tonnes of smelting
capacity idle.
When reviewing smelting capacity for possible
curtailment, Alcoa will consider a wide
variety of alternative actions, ranging from
discontinuing pot relining to full plant curtailments
and / or permanent shutdowns. Alcoa’s
alumina refining system will also be reviewed
to reflect any curtailments in smelting as well
as prevailing market conditions.
Alcoa’s review of its primary metals operations
is consistent with its 2015 goal of
lowering its position on the world aluminium
production cost curve by 10% points and the
alumina cost curve by 7% points.
Early in June Alcoa released it is piloting
a new emissions reduction technology at its
baked anode and calcined coke facility in
Lake Charles, Louisiana, that will reduce sulphur
dioxide, particulate matter and hydrogen
fluoride emissions at the plant by up to 90%.
The new technology also offers significantly
lower installation costs than more established
emission-cleansing technology, as well as lower
operating cost, using half as much water and
30% less energy.
Whereas conventional wet scrubbers pump
a limestone or sodium-based solution to the
top of a 100-foot (31 metre) tower and spray it
onto flue gas, Alcoa’s in-duct scrubber moves
flue gas from the smelter or boiler into a horizontal
chamber and sprays a sodium-based
solution in the same direction as the gas flow.
This high-velocity, horizontal scrubbing process
allows up to three times more gas to be
treated than in an equivalent conventional
scrubber space, and it requires 30% less energy
to operate. The technology treats upwards
of 90% of sulphur dioxide in less than onefifth
of a second, compared to traditional wet
scrubbers, which could take 10-15 seconds.
Commissioning and testing of the new technology
is expected to be complete by August
2014.
In May bankrupt aluminium company
Ormet was sold to an entity owned by private
equity firm Wayzata (Minn) Investment
Partners. The Ohio-based company had originally
been scheduled to go to auction, but the
auction was cancelled because no bids besides
that from stalking-horse bidder Smelter Acquisition,
a Wayzata entity, were received.
The exact purchase price for Ormet was
not disclosed. The company reported assets of
USD407m and total liabilities of USD416m
when it filed for Chapter 11 bankruptcy. High
legacy and power costs as well as low aluminium
prices pushed the company to seek
bankruptcy protection.
Ormet’s smelter in Hannibal can produce
up to 270,000 tpy of primary aluminium when
operating at full capacity, and its alumina refinery
in Burnside, Louisiana, can produce
540,000 tpy of smelter-grade alumina.
In June, the US Bankruptcy Court for the
District of Delaware approved the sale of
substantially all of the assets of Ormet Corp.,
to Smelter Acquisition, LLC, a portfolio company
owned by private investment funds managed
by Wayzata Investment Partners LLC.
For this restructuring, the company received
aggregate commitments of USD90m of DIP
Financing, consisting of USD30m in Term
DIP financing from Wayzata, as well as a US-
D60m DIP facility from Wells Fargo, which
replaced its USD60m pre-petition revolver
with Ormet. The DIP financings provided the
Company with sufficient liquidity to meet its
ongoing obligations and to ensure that its operations
continue without interruption during
the restructuring.
The purchase from bankruptcy by Smelter
Acquisition means that the business will shed
substantially all of its legacy liabilities and will
emerge with a much stronger balance sheet
and sole equity sponsor in Wayzata. The company
does not anticipate that the acquisition
will impact Ormet’s ordinary course of operations.
In June Ormet’s sale to Smelter Acquisition
was approved by the US Bankruptcy
Court in Delaware.
VENEZUELA: In February aluminium
producer CVG Alcasa said it will increase its
output to 170,000 tpy, using new machinery
obtained with a USD402m investment approved
by President Hugo Chávez back in
2012. The new equipment was supplied by
China Aluminium International Engineering
Corp. (Chalieco), and will be incorporated
progressively over the next two years. It
represents the first technological adequation
process made by Alcasa in 25 years.
OCEANIA
NEW ZEALAND: In April Rio Tinto’s Pacific
Aluminium unit was still in talks with energy
supplier Meridian to renegotiate terms for
New Zealand’s only aluminium smelter, after
it rejected a short-term subsidy by the government
to keep the plant running. Pacific Aluminium’s
view is that a commercial agreement
can be reached through a NZAS electricity
supply contract, that is in the best interests of
NZAS, Meridian, the New Zealand Government
and the people of Southland. Under the
existing contract, NZAS must operate until
2016, and can then be progressively closed,
and it would be expensive for Rio Tinto to
shut it down faster.
NZAS uses about 15% of the nation’s
electricity output. Closure of the plant would
mean a massive power surplus in the nation
that is looking to divest stakes in three stateowned
electricity firms. About 90% of output
by NZAS is exported, with Japan being its
biggest market. NZAS contributes USD525m
to the Southland economy annually – about
3% of New Zealand’s GDP – and supports
more than 3,200 direct and indirect jobs in
Southland.
EUROPE
BOSNIA: Early in June Bosnian aluminium
smelter Aluminij Mostar announced to shut
down all operations in mid-June due to losses
made on high power costs and low aluminium
prices. On 20 June the company said that it
had decided to delay the closure by 17 July

“due to positive developments that occurred
after we had informed the public on our decision.”
CEO Ivo Bradvica’s proposal to close operations
was unanimously approved by the
company’s supervisory board after reviewing
a business report for the first four months
of 2103. This revealed losses of 9.7m marks
(USD6.5m) per month since the start of the
year.
The decision had been taken during a supervisory
board session, which the leadership
of the independent trade union also attended.
These representatives of the plant’s employees
also realised that there is no alternative to
the closure. Aluminij produces about 130,000
tpy of aluminium through a tolling agreement
with Glencore Xstrata, and employs around
900 people.
FRANCE: At the end of 2012, Rio Tinto Alcan
was ordered to stop insisting that companies
licensing its Aluminium Pechiney smelting
technology must also buy pot-tending assembly
handling equipment from its subsidiary
Electrification Charpente Levage (ECL). The
European Commission made legally binding

practice as a condition of lifting a threat of
anti-trust fines in the European Union. Brussels
had feared that Rio Tinto was potentially
dominating the aluminium smelter equipment
market through its licensing system, damaging
competition within the EU.
Under the agreement, users of Rio Tinto
Alcan’s technology can not only choose from
recommended suppliers, but Rio Tinto must
also provide competing pot-tending assembly
suppliers with technical specifications, to ensure
their equipment can work in Aluminium
Pechiney smelters.
Brussels’ investigation began after Francebased
crane manufacturer Réel complained
about the practice, for which Rio Tinto offered
commitments in August 2012, which have now
been accepted by the Commission and made
legally binding. If the company breaches the
conditions, the Commission could impose a
fine of up to 10% of Rio Tinto’s total turnover.
GERMANY: Trimet Aluminium, Germany’s
largest producer of primary aluminium,
confirmed in March that the company was in
talks with Rio Tinto Alcan to acquire two aluminium
plants in France, namely the sites at
Castelsarrasin and Saint-Jean de Maurienne.
The Saint-Jean de Maurienne plant in eastern
France is an aluminium smelter of about
140,000 tpy. Talks are still underway.
ITALY: In June, Alcoa agreed to maintain
the shuttered Portovesme aluminium smelter
in Italy until the end of June 2014, rather than
just to the end of 2013, to allow more time
for a possible sale. However, the ministry does
not take for granted the failure of the deal
with Klesch, and reserves the right to contact
the group again to further investigate the
terms of negotiation. Simultaneously, it said
it would continue scouting for other potential
buyers at both the national and international
level. The Portovesme smelter had fully
ceased production in November 2012, after a
possible sale to Glencore fell through.
After more than three years of reduced
production, Alcoa finally decided to permanently
close its Fusina smelter in Venice. The
closure will reduce Alcoa’s global production
capacity of 4.2m tpy by 44,000 tonnes. This
tonnage is in addition to the 460,000 tonnes
of operating smelting capacity that Alcoa previously
announced was under review. The
Alcoa Fusina rolling mill operates separately
from the smelter and is not affected by this
decision.
NORWAY: In March Hydro said it was developing
new and energy-efficient aluminium
production technology as the foundation for
its long-term efforts. Hydro is therefore studying
the potential for testing next-generation
electrolysis technology at a pilot plant with
a capacity of about 70,000 tpy at Karmøy in
Norway. If the pilot project is realised, Karmøy
will host the most energy-efficient aluminium
production in the world, according to Hydro.
There are a number of elements that must
fall into place before Hydro can break ground.
The power grid in the region must be dimensioned
to meet the demands of the offshore
power industry and industrial development.
The company must also secure enough power
under competitive conditions and establish an
agreement with Enova on financing, in which
Enova can contribute considerable – and crucial
– support. Enova is owned by the Norwegian
Ministry of Petroleum and Energy and
has as its goal to promote environmentally
friendly alternatives in energy consumption
and energy production in Norway.
In June Hydro signed an agreement with
Rio Tinto Alcan to acquire its 50% ownership
share in the Vigeland Metal Refinery AS and
100% ownership share in the AS Vigelands
Brug hydropower station, located in southern
Norway. Hydro held a 50 % ownership
share in Vigeland Metal Refinery AS prior to
the transaction, and was the sole off-taker of
its production of high-purity aluminium. High
purity aluminium plays a vital part in semiconductors
and in several electronic applications
such as LCD screens for TVs, computers, cell
phones and tablets.
Located in Vennesla at the lower part of
the Otra River, the Vigeland Metal Refinery,
has a capacity of 8,500 tpy of high-purity aluminium.
The transaction will be notified to the Norwegian
Competition Authority, and Hydro
will also apply to Norwegian authorities for
an approval to acquire the hydropower assets
in AS Vigelands Brug.
RUSSIA: In February Rusal announced
that it started pilot testing of inert anode technology
in a 3 kA amperage cell at the Krasnoyarsk
aluminium smelter (KrAZ). For inert
anode technology Rusal has developed a completely
new pot design. Following successful
pilot tests, Rusal will start industrial tests in
inert anode pots in 2015 at KrAZ. From 2017
Rusal may start shifting smelting capacities
to inert anode technology, starting at KrAZ.
The burning speed of an inert anode is 300
to 400 times slower than that of a traditional
carbon anode, and wears away only 1-2 cm
per year, compared to 1-2 cm per day with
the carbon anode. The project joined the
Skolkovo foundation in June 2011. Planned
co-financing of the inert anode aluminium
production research from the foundation
amounts to RUR750m (USD25m) until 2015.
To date, RUR130m (USD4.3m) has already
been spent by Skolkovo.
In June the first phase of the Boguchansky
aluminium plant (BoAZ) was 75% complete.
As of 1 May the partners had already invested
about USD862m in the construction, which
needs another USD749m to complete the
first phase of BoAZ’s production capacity of
298,000 tpy. The first metal is expected in Q4
2013. Full capacity of the first phase will be
reached by the end of this year.
Also in June Rusal and IES Holding announced
an agreement on the sale of Rusal’s
Bogoslovsk aluminium smelter, which will enable
Rusal to form a single production facility
in Krasnoturinsk. The deal will be closed in
August 2013. Creation of a single industrial
complex will enable Rusal to reduce the cost
of production of alumina in the Bogoslovsk
aluminium plant. Rusal will keep the alumina
refinery which will be part of the Alumina
division.
In June Rusal signed an agreement with
the Leningrad region and the trade union
committee Volkhov Aluminium Plant (VAZ)
concerning plans to reorganise production in
the industrial area VAZ. The reorganisation
involves changing from producing primary
aluminium to producing high value added
products such as aluminium automotive components.
The parties signed an agreement in
order to save jobs, to create joint ventures with
potential investors producing end products
for mechanical engineering, and to establish
conditions for the long-term development of
industry in the region.

Keops Technologies deploys a new
standard aluminium smelter MES solution
Keops Technologies, Inc. is currently deploying
a new standard aluminium MES
(Manufacturing Execution System) solution
for the Ma’aden/Alcoa joint venture.
Encompassing the electrode, general
plant, and casthouse areas, the deployed
functionalities will enhance the ability of
the site to manage its production.
After months developing a standard MES application
based on Alcoa smelter and casthouse
functionalities, Keops Technologies – a leading
provider of MES systems serving the aluminium
industry – is presently on site, deploying
process and production control applications
with planning and scheduling functionalities
for managing daily operations.
The Ma’aden project represents specific
challenges given the integration with the rolling
mill and high quantity of daily metal production.
This increases the complexity of the
casthouse scheduling system that Keops has
designed, having to respond to a very shortterm
demand. The coordination between upstream
molten metal flows from the potline
and downstream remelt and cold scrap management
from the rolling mill has been modelled
to sequence all operations: pot tapping,
trip scheduling of crucibles to the casthouse
and shipments of casthouse products to the
rolling mill, while respecting quality, equipment
and process constraints.
In addition, the MES tool supports managers,
supervisors and engineers to optimise
their business processes by providing timely
information directly collected from the many
equipment and systems from the port to the
casthouse, through the carbon and reduction
areas. Connecting to PLC and external systems
– for example the LIMS – through proprietary
interfaces, the Keops MES solution provides
an integrated view of production information
to support critical decision-making processes.
The detailed execution plan or process data is
then interfaced in two directions: either downward
to the production systems with production
and process parameters, or upward towards
the ERP or rolling mill MES. Production
information is also fed to the manufacturing
infrastructure, which plant personnel can use
as needed to monitor production performance
and to drill down into detailed data.
The deployment is concentrated over a
short period of time by taking advantage of
Keops’ experience in greenfield and brownfield
projects, and its agility in quickly providing
a wide range of subject matter experts
for each of the sectors and subsystems. Keops
also benefits from its large library of interfaces
with third-party applications, accumulated
with various industry vendors during its
over-30 years of experience in the aluminium
industry.

Durch das schlanke Design ist die Streckenführung
des Systems sehr flexibel.
Dadurch wird auch die Montage an der

increasing its disposability for other operations,
saving labour and avoiding dust emissions
to the environment.

Exterior view of the plant with 64 electrolysis cells, upgraded with the
fully automatic pot feeding system Durodense for alumina
With this Coperion complements Dubal’s
undertaking to retrofit their older potlines
to optimise energy consumption with higher
efficiency and reduced perfluorcarbone emissions
being environmentally par with other advanced
technologies. With this project, Coperion
has proven once again to be the competent
partner for a technologically driven modernisation
project in the aluminium industry.
With Durodense, Coperion offers a sustainable
solution to supply alumina to the reduction
process in aluminium smelters. It meets
the requirements of new greenfield smelter
projects as well as of brownfield modernisation
projects.
High operating reliability
Durodense is built of a modular system body
consequently using round shaped standard
piping with internal product fluidisation for
the most gentle product transport. Due to
such slim design the routing
of the system is very flexible
and as a consequence the installation
at and the penetration
through an existing pot
room wall structure is eased.
This is also advantageous especially
at the pot superstructure
compared to other, more
space requiring systems, says
Coperion. With the utilisation
of standard couplings the use
of standard piping minimises
problems with sealing and
thermal expansion.
The Durodense system has
its very high operating reliability
due to the following facts:
• The main distribution pipe
along the potroom is constantly
filled to almost 100 percent
with alumina. The whole
© Coperion
system serves as an alumina
buffer located close to the
cells. Through this fact very
high instantaneous filling rates
into a cell hopper are possible.
Even cell technologies with a
strong fluctuating filling level
in the cell hopper can be filled immediately.
• The system is equipped with a special air
distribution system inside its fluidisation elements.
These devices assure that in case of
plug formation the air cannot bypass the plug
but is forced into the alumina plug and dissolves
it.
• The air consumption for the total system
from silo to pot during normal operation is
less than 0.6 to 0.7 m 3 /min per pot and very
38 ALUMINIUM · 7-8/2013

SPECIAL
ALUMINIUM SMELTING INDUSTRY
constant. This leads to a very low material
velocity in the piping and avoids the risk of
scaling. The low and constant air consumption
causes a low impact on the gas balance of the
potroom, a low impact on the gas treatment
centre (GTC) and a low impact on the roof
emissions as well. This is a very important
benefit especially for revamping projects with
existing GTCs and related gas balances.
• The system does not need any sensor or actor
(gates, valves) at the pots; it is completely
self-regulating. This eliminates the investment
cost for sensors, actors and related cabling
and control boxes compared to other existing
automatic systems.
These features of the Durodense pot feeding
system provide clear benefits for new
smelter projects as well as for modernisation
projects.
After the successful realisation of the alumina
and petcoke handling and storage facilities
in the port of Qatalum and the bulk handling
facilities in the courtyard areas of the
Ma’aden smelter, Coperion now completes
the material handling chain with the successful
operation of the Durodense pot feeding system
in the Dubal smelter.

The Opticast system is proving to be an invaluable
tool in carrying out assessment and control
of grain refinement practice in industrial
Fig. 2: Grain refiner curves for two master alloys with different efficiency
casthouses by using data generated from sampling
the melt in real time. Originally conceived
by Lennart Backerud [2] and co-workers at
Stockholm University, and since that time extensively
developed, tested and refined, the
Opticast technology is today being used for
optimisation and control of grain refinement
practice in casthouses worldwide.
It produces rapid and reliable results so
that accurate conclusions can be quickly made
regarding implementation of optimised grain
refining practice.
Implementation of the Opticast system in
the casthouse entails the following steps: calibration
and sampling in casting furnace.
Calibration involves establishing how a
specific alloy responds to addition of fresh
nuclei via the grain refining rod, in other
words establishing the equations for the grain
refinement curves as shown in Fig. 2. It shows
a test carried out with
two different batches of
the same grain refiner
in the same alloy melt.
Obviously one batch
is more efficient than
the other and it follows
that if both grain refiners
are being used in a
casthouse, the calibration
must be done to handle
any variations in the grain
refiner efficiencies, that is

a best and worst case scenario. This means that
the calibration equation must be set up for the
upper of the two curves and is for the lower
one as well. The practical implication of this is
that there is much to gain if the grain refiners
used have a consistently high efficiency from
batch to batch.
Optifine
Establishing that grain refiner variability is an
important consideration factor in achieving a
fully optimised practice has led to the development
of a consistently powerful titanium boron
master alloy grain refiner, Optifine.
Optifine is produced via a special production
route, which substantially optimises its
nucleation potential. In standard TiBAl grain
refiners only 1% of particles are active, and
large boride particles and agglomerates lead
to preferential formation of large grains
whereas studies have shown that particles in
the size range 1-3µ are optimum for nucleation.
Optifine has been found to have over six
times more active nuclei per ppm of boron

than standard grain refiners and promotes
fine equiaxed structures. Its efficiency as a
grain refiner is at least twice, sometimes up to
thirty times higher than standard Ti Bal refiners
normally used.
An independent metallographic study also
shows that Optifine grain refiner has a very

uniform microstructure (Fig. 4) without denuded
zones or TiB2 clusters that can be seen
in the typical standard Ti Bal grain refiner
(Fig. 3).
Casthouse trials at a
remelt casthouse – Hulamin
A trial programme carried out using the Opticast
system in conjunction
with Optifine grain refiner
showed that adequate
grain refinement could be
achieved in all of the AA alloy
groups that Hulamin produces
with additions in the
range 0.1 kg/t up to 0.24 kg/
t compared to the 0.34 kg/t
up to 0.78 kg/t previously
used with a standard TiBAl
(Fig. 5). Expressed in percentages
this means reductions
of 56-81% in addition
rates.
Following these trials
Optifine usage has been implemented
in full production
resulting in overall grain refiner usage
being reduced to 45 tpy.
Conclusion
Optifine is a very potent grain refiner which
allows reduction of addition rates to extremely
low levels over a range of AA alloys. Since
Optifine has a consistent high potency, and the
grain refinement process can be closely monitored
with the Opticast method, there is no
risk for cracking of ingots and billets.
Improvements in cast ingot quality can be
expected due to consistent grain size, lower
levels of borides, boride agglomerates and oxides
introduced as a result of the substantial
reduction in grain refiner addition as well as
the uniform nature of the Optifine grain refiner
microstructure.

Achieving maximum output when insulating electrolysis cells
S. N. Bertel and H. R. Østergaard, Skamol A/S
A wide variety of insulating materials are
available on the market and it can be difficult
to understand the benefits of one
material compared to another. However,
key factors to consider, when insulating
electrolysis cells in the aluminium industry,
are the products’ impact on heat loss,
cell efficiency and installation process.
These factors can among other things improve
performance efficiencies, prolong
the lifetime of the cells and increase time
between relining.
Insulation – a key to
an efficient production
One of the challenges often faced in the aluminium
industry is achieving a cost-efficient
electrolysis cell. This involves being able to
keep a stable heat balance in order to reduce
energy costs and to minimise the risks and the
effects of penetrating gasses, bath and molten
aluminium. It also involves a more efficient
relining process, where time is the key factor,
but also a process that embraces the fact that
the physical environment in many work places
is becoming increasingly important. Insulating
the electrolysis cells with highly efficient insulation
materials can contribute to a solution
to these challenges by bringing benefits like
an energy-efficient production with focus on
reducing heat loss, improving cell efficiency
and also contributing to an efficient relining
process.
Testing insulating materials
There is a wide range of materials available
on the market and among these
are calcium silicate insulating boards
and fibre-based boards. These products
are among some of the world’s most
efficient materials when insulating electrolysis
cells – their low thermal conductivity
combined with their specific
product characteristics provides highly
insulating solutions that are easily installed
thus ensuring an efficient production
with a minimum of heat loss.
Low thermal conductivity contributing
to a stable heat balance
Calcium silicate and fibre-based boards
are both highly insulating products and
the use of either product can contribute
It is the needle-like micro-structure of the calcium
silicate that provides significant strength to the
boards and maintains it at high temperatures
to reduced heat loss, energy savings and to an
improved control of the production process
by contributing to maintaining a stable heat
balance inside the cells. The calcium silicate
insulating boards, Super-Isol and Super 1100
E from Skamol A/S, both have a thermal conductivity
of 0.14 W/(m*K) at 800 °C, which is
among the lowest in the industry. Recent independent
tests conducted to ASTM C-201/182
in 2013 conclude that the thermal conductivity
of these two calcium silicate insulating
boards is 27% lower than a leading bio-soluble
fibre-based board between the operating
temperatures of 600 to 800 °C. The test was
conducted at several temperatures from 250
to 800 °C and the results vary from a difference
of 18% at 600 °C to 27% at 800 °C – all
in favour of calcium silicate. The reason for
the low thermal conductivity of calcium silicate
can be found in the structure of the product.
To obtain a good insulation value at high
temperatures, the insulating product has to

set was delivered according to the specific measurements of this cell, which
reduced installation time significantly.

have a well-defined pore size – the smaller the
pores, the higher insulation value is obtained
when exposed to high temperatures. The structure
of small pores with relatively short distances
from fix point to fix point makes the
calcium silicate highly insulating compared to
fibre-based boards that are structured by large
pores and, as a result, have a lower insulation
value.
A prolonged lifetime of the cell
Besides finding a highly insulating solution,
another aspect to consider is the strength
and compressibility of the product in order
to avoid damages to the insulation material
from heaving cathode blocks. When infiltrating
the cathode blocks, gas, bath and molten
aluminium can cause the blocks to heave and
the insulation material becomes in danger of
compressing due to the increased pressure.
When the insulation material is compressed,
the insulation value of the product will be decreased
and the direct result is a significant
increase in heat loss (cell voltage drop) and
the electrolysis cell will be taken out of operation.
The Super-Isol and Super 1100 E calcium
silicate boards both have a compressive
strength of 2.6 MPa at room temperature making
them 700-800% stronger than comparable
bio-soluble fibre-based boards that have
a compressive strength of approx. 0.30 MPa.
The reason for this difference is evident when
looking at the structure of the products. To obtain
strength to the fibre-based
boards, an organic binder is
added in the manufacturing
process and the compressive
strength reaches approx. 0.30
MPa. However, this binder
burns off at approx. 400 °C
and so the strength disappears
with the consequence of the
fibre-based boards compressing
and the insulating lining
becoming unstable. This is not
the case with calcium silicate
due to its microstructure and
the fact that the pores inside
this product are intertwined,
which makes the use of binder
unnecessary. Calcium silicate,
therefore, is able to maintain
strength better than fibrebased
boards.

Increasing space and
enhancing protection
Efficient insulation not only means a highly
insulating and strong product, it also refers to
a product that is, to a certain extent, able to
resist the influences from destructive gasses,
etc. In the aluminium industry and especially
in electrolysis cells, the risk of fluoride and
sodium gasses, bath and molten aluminium
penetrating the cathodes, graphite blocks,
ramming paste and lining material is always
present. These facts make it important to have
a solid layer of barrier bricks that is able to
withstand this kind of aggressive environment
and underneath it, a strong insulation material
that is able to withstand these substances
if these destructive forces should reach them,
thus avoiding damage to the entire cell.
The calcium silicate boards from Skamol
contain a lot of small pores, which provide
them with low gas permeability. These small
pores make it hard for the gasses to penetrate
the product and hence, the insulation value
remains intact. Combined with the low degree
of compressibility and the fact that they retain
significant strength up to approx. 900 °C with
only a 5% creep in compression, the calcium
silicate insulating boards will provide a stable
lining that is protected from gas attacks. The
fibre-based boards, however, consist of large
pores, making them vulnerable to e.g. gas attacks,
because of the fact that the gasses condense
and freeze inside the boards at 700 to
720 °C thus diminishing the thermal conductivity.
Combined with the risk of creating gaps
inside the cell, due to the risk of the material
compressing, gas etc. can penetrate the lining
and a risk of damage to the lining and increasing
heat loss is created.
Although carefully lined with a strong insulating
product and highly resistant barrier
bricks, gas, bath or molten aluminium will
always, to some extent, be able to penetrate
the carbon / graphite. Therefore, many smelters
are trying to figure out ways of increasing
the protective layer of barrier bricks while
maintaining a highly efficient insulation of
their electrolysis cells in order to protect the
lining material. Even at small thicknesses,
the low thermal conductivity of the calcium
silicate insulation board opens up for the
possibility of decreasing the thickness of the
insulating lining – making more room for an
increased layer of barrier bricks. The calcium
silicate insulating board, Super-Isol and Super
1100 E from Skamol, can be delivered with
a single layer up to 100 mm thickness while
maintaining a low thermal conductivity of
0.14 W/(m*K). Besides being able to increase
the layer of barrier bricks, reducing the thickness
of the insulating material also makes it
possible to install bigger cathodes. This can,
other things being equal, prolong the lifetime
of the cell due to the fact that most cells are
taken out of operation, when the cathode
block is worn down. A combination of a reduced
refractory layer and bigger cathodes
is also possible – making the cell even more
efficient.
Using calcium silicate can not only provide
more space and protection of the electrolysis
cells, it can also be installed in combination
Calcium silicate boards are easily installed and dismantled
without health risks
with castable material. In cases where castable
material is applied directly onto the back-up
lining material in order to e.g. even out gaps
between the materials, calcium silicate boards,
like the Super-Isol and Super 1100 E, can be
surface-treated to be water-repellent. The water
repellent surface makes them unable to
absorb water from the castable material and
the risk of using this product, whether installing
barrier bricks or applying castable material
directly onto the boards, is non-existent.
Shortening the installation process while
improving the physical environment
Relining electrolysis cells lasts approx. 5 to 7
days from when the cell is turned off to restarting
it again including the cooling and relining
time, depending on the size of the cell and
the complexity of the process at the specific
aluminium smelter. This is done manually and
a contractor is often hired to do the work and
it is a process that is connected with many
costs. Combined with the pursuit of minimising
cost due to the decrease in aluminium prices,
these costs are often sought reduced.
Insulation materials like the calcium silicate
insulating boards and fibre-based boards are
mostly delivered as whole boards in standard
sizes making it necessary to cut the products
before installation as the electrolysis cells are
often shaped with round corners and conical
walls. Although both products are easily
handled and cut, more and more smelters in
the aluminium industry see the advantages of
installing pre-cut boards ready for installation
without further adjustments. This opens
up for the possibility of reducing installation
time significantly as no further measurements
and machining of the product is necessary and
the product can easily and quickly be installed.
The calcium silicate pot sets from Skamol can
be placed on the pallets according to the sequence
that they will be used on site, reducing
the inventory and shortening the installation
process significantly.
Although relining can be done more efficiently
and a long lifetime of the cell can
be achieved using the right combination of
production process and insulating material,
relining will continue to be a recurrent event
for aluminium smelters and so, protecting the
health of the people working with and around
the cells during relining is still an important
factor. The calcium silicate board, Super-Isol
and Super 1100 E, has been classified as nonhazardous
by government bodies worldwide,
so there is no risk of handling the product.
This is due to the fact that the product is manufactured
as 100% fibre- and shot-free and
therefore does not emit hazardous dust. This
is also the case during dismantling of the product
opposed to fibre-based boards – though
easily managed and cut – the silica inside the
fibre boards crystallises over time and they
thereby pose a health risk especially during
dismantling which makes it important to wear
a lot of personal protective equipment. Calcium
silicate is therefore a healthier solution.
Calcium silicate insulating
boards from Skamol
Calcium silicate insulating boards from Skamol
were developed and introduced to the market
in the 1980s. Since then, the material has been
used extensively throughout many industries,
including the aluminium industry, where it is
primarily used as sub-cathodic and sidewall
insulation to improve the thermal efficiency
of energy-intensive processes. Skamol is one
of the leading suppliers of insulation solutions
to the aluminium industry, and the Skamol
calcium silicate board is used by aluminium
smelters all over the world from Norway to
New Zealand, Canada and Abu Dhabi etc.

F. Niedermair, Hertwich Engineering
At its plant in Essen Trimet Aluminium
SE has set up an air-cooled ingot casting
unit. The installation, supplied by Hertwich
Engineering, supplements the range
of equipment at the casthouse in Essen
and extends the company’s delivery options.
The business model of Trimet Aluminium has
made it possible for the company to produce
aluminium successfully even under the by no
means favourable local conditions that prevail
in Germany. Trimet regards itself as a materials
partner for aluminium processors, offering
its customers tailor-made products. In support
of that claim the company has continually extended
its product range.
Currently Trimet produces some 150 different
formats in 450 alloys (including bright
materials) as well as special grades in accordance
with customer specifications. In this, an
important role is played by products for the
manufacture of safety-relevant components
for the automotive industry, which can be supplied
with a zero-defect guarantee after being
tested on Europe’s most modern ultrasonic
(US) testing unit.
Casthouse extension for new products
For its extensive product range the casthouse
in Essen has the following equipment in total:
• 14 furnace units and another furnace for
melting down swarf and chips
• nine vertical continuous-casting units for
semis in various formats
• one continuous-throughput and eight
batch homogenising furnaces
• a fully automatic US-testing unit for
round bars
• a horizontal continuous-casting unit for
ingot production, and
• an R & D continuous-casting plant,
including its own homogenising furnace.
The plant produces around 250,000 tonnes
a year, of which 160,000 tonnes come from
the company’s own primary production and
90,000 tonnes from recycled material.

or by casting into moulds. In Essen, until now
only one automatic, 24-strand horizontal casting
machine was available for producing such
material for delivery. By supplying mould-cast
ingots Trimet can now satisfy the expectations
of many of its customers.
Another aspect of this is that Trimet anticipates
increasing demand for casting alloys,
some of which, such as hypereutectic AlSi and
AlCu alloys, cannot be cast using a horizontal
continuous-casting unit.
New ingot casting plant with air cooling
For that reason too, among others, in 2011
Trimet decided to invest in a modern ingot
casting plant. As its equipment partner for the
project Trimet opted for Hertwich Engineering,
a subsidiary of the SMS group and market
leader in the field of casthouse equipment for
the aluminium industry.
Hertwich produces
both horizontal continuous-casting
machines
and batch-type
ingot casting units
(with metallic moulds).
The present-day mould
casting concept goes
back to the year 2000:
at that time Austria
Secondary Aluminium
(ASA) set Hertwich
the task of providing a
new type of ingot casting
unit whose concept Cooling zone
differed from the versions
then available on the market in a number
of particular respects. The criteria, among others,
were:
• a plant fully automated from the pouring
of the metal to the bundle of ingots ready
for dispatch, having high performance and
being designed in a space-saving manner
• Primary cooling as far as complete solidification
in the mould should be done with
air; until then water cooling was standard.
The result was the concept of an air-cooled and
water-cooled casting belt, with which the solidification
can be controlled very precisely. This
design, which combines high product quality
with economical and environmentally acceptable
operation, proved persuasive to Trimet in
its investment decision.
Plant and working method
The plant installed at Trimet for ingots weighing
between six and ten kilograms achieves a
maximum casting rate of ten tonnes an hour.
Kühlstrecke
fügt die Essener Gießerei über insgesamt
• 14 Ofenanlagen sowie einen Späneofen
• neun vertikale Stranggießanlagen für
Halbzeugformate
• eine Durchlauf- und acht Kammerhomogenisieranlagen
• eine vollautomatische Ultraschallprüfanlage
für Rundbarren
• eine Horizontal-Stranggießanlage für die
Masselproduktion sowie
• eine F&E-Stranggießanlage einschließlich
Homogenisieranlage.
Die Jahresproduktion des Werkes beträgt derzeit
etwa 250.000 Tonnen, die sich aus 160.000
Tonnen eigener Primärerzeugung und 90.000
Tonnen Recyclingmaterial zusammensetzt.
Gusslegierungsmasseln können wahlweise
im Horizontal-Strangguss oder im Formguss
erzeugt werden. In Essen stand für diese
Lieferform bisher ausschließlich eine automatische
24-strängige Horizontal-Stranggießanlage
zur Verfügung. Mit der Lieferung von
Formgussmasseln entspricht Trimet nun den
Erwartungen vieler Gießereikunden.
Hinzu kommt ein weiterer Aspekt: Zukünftig
werden nach Einschätzung der Trimet
verstärkt Gusslegierungen nachgefragt, die
nicht auf einer horizontalen Stranggießanlage
gegossen werden können, wie beispielsweise
übereutektische AlSi- und AlCu-Legierungen.
Neue Masselgießanlage mit Luftkühlung
Auch aus diesem Grunde hat sich Trimet 2011
zur Investition einer modernen Masselgießanlage
entschlossen. Als Ausrüstungspartner
entschied sich das Unternehmen für die österreichische
Hertwich Engineering, ein Tochterunternehmen
der SMS group und Marktführer
bei Gießereiausrüstungen für die Aluminiumindustrie.
Hertwich baut sowohl horizontale Stranggießanlagen
als auch Masselgießanlagen (Kokille).
Das moderne Kokillen-Gießkonzept
geht auf das Jahr 2000 zurück: Damals hatte
die Austria Sekundär Aluminium (ASA) Hertwich
aufgefordert, eine neuartige Masselgießanlage
anzubieten, deren Konzept sich von den
seinerzeit am Markt erhältlichen Bauformen
durch eine Reihe besonderer Merkmale unterschied.
Kriterien waren unter anderem:
• eine vom Metalleinguss bis zum versandfertigen
Masselbund voll automatisierte
Anlage mit hoher Leistungsfähigkeit und
in platzsparender Ausführung
• die Primärkühlung bis zur vollständigen
Erstarrung in der Form sollte mit Luft
erfolgen; bis dahin war die Wasserkühlung
Standard.
Im Ergebnis entstand das Konzept des luftund
wassergekühlten Gießbandes, bei dem
sich die Erstarrung sehr präzise steuern lässt.
Diese Bauform, die eine hohe Produktqualität
mit wirtschaftlicher und umweltgerechter Betriebsweise
verbindet, hatte auch Trimet bei
deren Investitionsentscheidung überzeugt.
Anlage und Arbeitsweise
An der bei Trimet installierten Anlage für
Masseln zwischen sechs und zehn Kilogramm
erreicht die Gießrate maximal zehn Tonnen
je Stunde.
Gießstation: Die abgebildete Gesamtanlage
zeigt links zwei Gießöfen mit Durchflussregelung.
Zwei unabhängige Ofenanlagen sind
zweckmäßig, um beim Legierungswechsel den
kontinuierlichen Betrieb aufrechtzuerhalten.
Über eine feuerfeste Gießrinne gelangt das
etwa 700 °C heiße Metall über einen Keramikfilter
zum Gießtrog, der während des Gießprozesses
synchron mit dem Gießband verfährt.
Die höhenverstellbaren Gießöffnungen
gewährleisten dabei eine präzise Dosierung
und einen weitgehend turbulenzfreien
Schmelzefluss. Die abgebildete Einrichtung
füllt jeweils fünf (vorgewärmte) Kokillen
gleichzeitig.
Die Kokillen durchlaufen, auf einem umlaufenden
Gießband montiert, die Kühlzone.
Der entscheidende Vorteil der neuen Masselgießeinrichtung
ist die deutlich geringere
Oxidbildung. Dieser Aspekt gehört zu den
qualitätsbestimmenden Kriterien, da Oxideinschlüsse
das Schmelzbad beim Wiedereinschmelzen
verunreinigen. Als ein weiterer
Vorteil kommt die präzise Gießsteuerung
hinzu, die unterschiedliche Masselgewichte
ausschließt.
Primärkühlung mit Luft: Um Erstarrungsrisse
zu vermeiden, kommt es zu Beginn der
Erstarrung darauf an, den Temperaturgradienten
zwischen Kern und Randbereich gering
ALUMINIUM · 7-8/2013 45

ALUMINIUMHÜTTENINDUSTRIE
zu halten. Die erste Zone der Kühlstrecke ist
deshalb so ausgelegt, dass Temperaturschocks
oder Wellenbewegungen der Schmelzeoberfläche
vermieden werden.
Die Primärkühlung erfolgt deshalb mittels
Luft. Die Kühlluftkanäle sind zwischen
dem Ober- und Untergurt des Gießbandes
angeordnet, sodass die Kühlluft nicht direkt
auf die flüssige Metalloberfläche auftrifft.
Die erwärmte Luft wird mittels zusätzlicher
Ventilatoren über dem Gießband abgeführt.
Wenn die Oberfläche komplett erstarrt ist,
gelangen die Kokillen in einen Bereich intensiverer
Luftkühlung. In diesem Bereich des
Gießbandes wird die Erstarrung vollendet.
Die Kühlintensität ist über die Ventilatorsteuerung
regulierbar.
Diese Art der Kühlung besitzt gegenüber
der Wasserkühlung metallurgische und wirtschaftliche
Vorteile. Im Hinblick auf die Produktqualität
sind dies unter anderem:
• dichtes Masselgefüge durch gezielt
gesteuerte Kühlwirkung
• optimale Einstellung der Kokillentemperatur
• Kokillen kommen nicht mit Wasser in
Kontakt.
Hinzu kommen bedeutende wirtschaftliche
Vorzüge der Luftkühlung:
• Nahezu unbegrenzte Kokillenlebensdauer
(keine Temperaturschocks)
• kein zusätzlicher Kühlwasserverbrauch,
keine Nebenanlagen oder Maßnahmen
zur Aufbereitung
• geringer Wartungsaufwand an Kokillen
und Gießband.
Sekundärkühlung mit Wasser: Die
Masseltemperatur nach dem Gießband
beträgt noch etwa 350 °C. Für
das weitere Handling – besonders für
das Farbmarkieren, für das Abbinden
mit Metall- oder Kunststoffband sowie
für das Etikettieren – muss die Temperatur
unter circa 50 °C abgesenkt werden.
Für diesen Kühlabschnitt setzt Trimet
Wasser als Kühlmedium ein.
Dazu durchlaufen die zuvor ausgeformten
Masseln einen Kühltunnel, in
dem Sprühdüsen installiert sind. Die
einstellbaren Sprühköpfe erlauben es,
die Kühlung für die jeweilige Aufgabe
zu optimieren. Am Ende des Kühltunnels
werden die herunter gekühlten
Masseln mittels Druckluft getrocknet.
Die Kühlwasserversorgung ist Teil
des zentralen Wasserkreislaufes des
Werkes. Hinter dem Kühltunnel wird
das Wasser wieder in diesen Kreislauf
zurückgeführt. Besondere Einrichtungen
sind für die Wasserversorgung
der Masselgießanlage nicht erforderlich.
Stapeln, Verpacken, Umreifen: Am Ende des
Kühlprozesses schließlich stehen voll automatisierte
Anlagen zum Stapeln, Markieren, Umreifen
sowie zum Wiegen zur Verfügung.
Im ersten Arbeitsschritt werden die gekühlten
Masseln stirnseitig signiert, paarweise (bei
Fußmasseln) bzw. lagenweise zum Stapeln
vorbereitet und schließlich von einem Industrieroboter
im anschließenden Verpackungssystem
abgelegt. Beim Stapeln werden die Lagen
über Kreuz auf den zuvor positionierten
Fußmasseln abgelegt. Mit einem Tintenstrahldrucker
wird jede Massel markiert.
In der Umreifungsmaschine wird der Masselstapel
schließlich mit Umreifungsbändern
versehen. Dabei verfügt Trimet über mehrere
optionale Möglichkeiten: So ist eine Auswahl
zwischen verschiedenen Bandmaterialien, der
Anbringung einer Querumreifung für gesteigerte
Stabilität oder die Bildung von Doppelstapeln
möglich.
Im Rahmen der Versandvorbereitung wird
der Stapel verwogen und etikettiert. Die Daten
werden vom Rechner an die Produktionssteuerung
und den Versand übermittelt.
Automatisierung: Der gesamte Ablauf vom
Eingießen in die Kokillen bis zur Entnahme
fertiger Stapel ist voll automatisiert. Jeder
einzelne Arbeitsschritt wird von speziellen
Überwachungs- und Diagnoseprogrammen
kontrolliert. Bei Abweichungen reagiert die
Steuerung unverzüglich. Es wird eine Fehlermeldung
generiert, die Aufschluss über die
Ursache der Störung sowie Vorschläge zur
Problemlösung enthält.

Stack of ingots before strapping
Casting station: The overall view of the plant
pictured shows on the left two casting furnaces,
each with throughput regulation. It is best
to have two independent furnace units in order
to maintain continuous operation even when
changing alloys.
By way of a refractory launder the metal, at
around 700 °C, flows via a ceramic filter into
the pouring trough. During the pouring process
the pouring trough moves synchronously
with the casting belt. During this the pouring
openings, whose height is adjustable, ensure
precise metering and largely turbulence-free
flow of the melt. The equipment illustrated
fills five (preheated) moulds simultaneously.
Positioned on a circulating casting belt,
the moulds pass through a cooling zone. The
decisive advantage of the new ingot casting
equipment is that much less oxide is formed.
This is one of the quality-determining criteria,
since oxide inclusions contaminate the melt
bath when remelting. Another advantage is
the precise control of the casting process,
which prevents variation of the ingot weight.
Primary cooling with air: To avoid solidification
cracks, at the beginning of solidification
the temperature gradient between the core
and edge areas must be kept small. The first
part of the cooling zone is therefore designed
to prevent thermal shock or wave movements
of the melt’s surface.
Accordingly, primary cooling is done with
air. The cooling air ducts are arranged between
the upper and lower strands of the casting belt
so that the air does not impinge directly on
the surface of the molten metal. The heated
air is drawn off by additional fans above the
casting belt. When the surface has solidified
completely, the moulds pass into a zone of
more intense air cooling. In this section of the
casting belt solidification is brought to completion.
The cooling intensity can be regulated by
the fan control system.
Compared with water cooling, this cooling
method has both metallurgical and economic
advantages. As regards product quality these
are, among others:
• a compact ingot such that due to
selectively controlled cooling action
• optimum mould temperature adjustment
• no contact between the moulds and water.
To the above can be added some important
economic advantages of air cooling:
• virtually unlimited mould life
(no temperature shocks)
• no additional cooling water consumption
and no auxiliary plant or preparation
measures
• less maintenance effort and expense for
the moulds and the casting belt.

SPECIAL
ALUMINIUM SMELTING INDUSTRY
Secondary cooling with water: After the casting
belt, the ingot temperature is still around
350 °C. For the subsequent handling procedures
– particularly colour marking, binding
with metallic or plastic strips and labelling –
the temperature has to be lowered to less than
around 50 °C. For the section in which this
takes place Trimet uses water as the cooling
medium.
For this the ingots, previously removed
from their moulds, pass through a cooling
tunnel in which spray nozzles are fitted. The
adjustable spray heads enable the
cooling to be optimised for the
job concerned. At the end of the
cooling tunnel the ingots, now sufficiently
cooled down, are dried by
compressed air.
The cooling water supply is taken
from the plant’s central water
circuit. After the cooling tunnel the
water is returned to that circuit. No
special equipment is needed for the
supply of water to the ingot casting
plant.
Stacking, packing and strapping:
Finally, at the end of the cooling
process fully automatic machines
are available for stacking, marking,
strapping and weighing the ingots.
In the first work step the cooled
ingots are marked on their end
faces in pairs (in the case of baselayer
ingots), prepared in layers for
stacking, and finally transferred by
an industrial robot to the nearby
packing station. During stacking the layers are
laid cross-wise onto the previously positioned
base-layer ingots. Each ingot is marked by an
inkjet printer.
In the strapping machine the stack of ingots
is then bound with strapping strips. For this
Trimet has a number of options: a choice between
various strip materials, the application
of cross-strapping for greater stability or the
formation of double stacks are all possible.
As part of the preparation for dispatch the
stack is then weighed and labelled. The data
are relayed by computer to the production
control and dispatch systems.
Automation: The entire sequence from
pouring into the moulds up to the dispatch of
finished stacks is fully automated. Each individual
work step is controlled by special monitoring
and diagnosis programs. In the event
of any departure from the norm the control
system reacts immediately. An error message
is generated, which contains conclusions about
the cause of the disturbance and proposals for
solving the problem.
In accordance with the stored order data, up
to three different orders can be processed in
a single batch. For each order the following
parameters can be programmed individually:
• ingot marking
• stack type
• stack weight
• base-layer ingots
• printing and design of the weighing label
• strapping pattern (number of strips) and
• nature of strapping strip.

Future prospects
The plant installed in Essen began operating
with no problems and is working to the customer’s
satisfaction. With a yearly production
volume of 35,000 tonnes, it is now already
fully occupied.
Clearly, the customers too appreciate this
new, additional supply form. Trimet answers
questions about the plant’s workload ambiguous:
“200 percent!” Accordingly, it may well
prove necessary to increase the casting capacity
even more in the foreseeable future.

The complete melting and casting furnace complex in the area of the new furnace
Neuer Schmelz- und Gießofen der Amag erhöht Gießereikapazität
Die Amag casting GmbH hat durch die
Investition in einen weiteren Schmelzofen
mit integrierter Gießfunktion an der
Produktionslinie EMC II eine deutliche
Kapazitätserweiterung bei Walzbarren in
EMC-Technologie geschaffen. Mit der an
dieser Anlage erzeugten Produktqualität
und der Erweiterung des Produktspektrums
wird die Position der Amag als
Premiumhersteller von Walzprodukten
weiter gefestigt.
Erstklassige Walzbarren sind die Grundvoraussetzung
für hochwertige Walzprodukte.
Die Walzbarrengießerei der Austria Metall
AG (Amag) aus Ranshofen, Österreich, gießt
ausschließlich für den Bedarf des eigenen
Walzwerks. Die Vielfalt an Walzprodukten
stellt besondere Anforderungen an die Kompetenz
und Flexibilität der Gießerei. Unter
einem Dach werden alle Al-Legierungsfamilien
von 1xxx- bis 8xxx-Werkstoffen vergossen,
wobei ein besonderes Knowhow in der
Verarbeitung von hoch- und höchstfesten
Legierungen der 2xxx- und 7xxx-Familien
aufgebaut wurde.
New melting and casting furnace
increases Amag’s casthouse capacity
By investing in an additional melting furnace
with integrated casting function at
the EMC II production line, Amag casting
GmbH has significantly increased the
capacity for rolling slabs using EMC technology.
The product quality achieved at
this line and the extension of the product
range contribute to further strengthening
Amag’s position as a premium manufacturer
of rolled products.
First-class rolling slabs are a basic requirement
for premium rolled products. The products
of Austria Metall AG’s rolling-slab casthouse
are solely intended for Amag’s own rolling
mill in Ranshofen. The wide range of rolled
products places special demands on the expertise
and flexibility of the casthouse. All
families of aluminium alloys, from 1xxx- to
8xxx-materials, are cast at one location; specific
know-how has been developed in the
processing of high-strength and super-highstrength
alloys of the 2xxx- and 7xxx-families.
Various continuous casting processes from
conventional vertical continuous casting and
LHC (Low Head Composite Casting) to EMC
(Electromagnetic Casting) are available to
meet the individual product requirements. As
Amag is continuously increasing the output
of rolled products, the company has to adapt
the casthouse capacity for rolling slabs. When
designing new facilities, the focus is always
on meeting quality requirements and increasing
flexibility to satisfy customer needs.
The appropriate furnace technology
for different type of scrap
When scrap metal is melted that contains aluminium,
it is essential to select the appropriate
furnace technology for the different raw
materials. Therefore, the scraps must be exactly
sampled and classified as soon as they
48 ALUMINIUM · 7-8/2013

TECHNOLOGY
are delivered. Covered storage of the scraps,
sorted by type, and batch planning based on
guidelines enable high-grade alloys and sizes
to be produced using raw materials in a costefficient
manner. Standardised guidelines also
ensure that, out of the large number of different
furnaces, the optimum melting technology
is selected for the individual scrap type.
The multi-chamber shaft melting furnace
technology is best suited for small-sized, thinwalled
and highly contaminated scraps. The
single-chamber melting furnace has proven
successful for largesized, slightly contaminated
scraps at Amag.
Capacity increase of the EMC machine
When a second electromagnetic casting machine
(EMC II) and a multi-chamber shaft melting
furnace were installed in 2009, the rolling
slab production capacity was significantly
increased in the wrought-alloy casthouse. In
late 2012, a new single-chamber melting furnace
with combined casting function, with a
bath capacity of up to 70 tonnes, was additionally
put into operation and integrated into
the existing site in a particularly space-saving
manner. This additional capacity increase at
the same time provides more flexibility for
the alloy mix. The new casting unit also al-

Entsprechend den Produktanforderungen
stehen unterschiedliche Stranggießverfahren
vom konventionellen Vertikalstrangguss über
LHC-Guss (Low Head Casting) bis hin zum
EMC-Guss (Elektro-Magnetic Casting) zur
Verfügung. Die kontinuierliche Steigerung der
Produktionsmenge bei Walzprodukten zieht
folglich auch eine Anpassung der Gießereikapazität
für Walzbarren nach sich. Bei der
Planung der Neuanlagen stehen dabei immer
Qualitätsanforderungen und die Erhöhung der
Flexibilität zur Erfüllung von Kundenwünschen
im Vordergrund.
Die richtige Ofentechnologie
je nach Einsatzmaterial
Ein wesentlicher Punkt beim Schmelzen von
aluminiumhaltigen Metallabfällen ist die Wahl
der richtigen Ofentechnologie für die verschiedenen
Einsatzmaterialien. Daher müssen die
Schrotte bereits bei Anlieferung genau bemustert
und klassifiziert werden. Die sortenreine
Lagerung der Schrotte unter Dach und eine
auf Richtlinien basierte Chargenplanung ermöglichen
die Produktion hochwertiger Legierungen
und Formate mit wirtschaftlichem
Einsatzmaterial. Standardisierte Richtlinien
gewährleisten, dass aus der Vielzahl an unterschiedlichen
Öfen die Wahl auf die optimale
Technologie zum Schmelzen der jeweiligen
Schrotte fällt.
Für kleinstückige, dünnwandige und stärker
verunreinigte Schrotte wird der Mehrkammer-Schachtschmelzofen
als die am besten
geeignete Technologie betrieben. Bei Einsatz
von grobstückigen, nur leicht verunreinigten
Schrotten hat sich der Einkammer-
Schmelzofen bei der Amag bewährt.
Kapazitätserhöhung der EMC-Gießanlage
Mit der Installation einer zweiten elektromagnetischen
Gießanlage (EMC II) und eines
Mehrkammer-Schachtschmelzofens im Jahr
2009 wurde in der Knetlegierungsgießerei
die Produktionskapazität für Walzbarren signifikant
erhöht. Gegen Ende 2012 wurde nun
ein neuer Einkammerschmelzofen mit kombinierter
Gießfunktion mit einem Badinhalt
von bis zu 70 Tonnen ergänzend in Betrieb
genommen und besonders platzsparend am
bestehenden Standort integriert. Mit dieser
neuerlichen Kapazitätserhöhung wurde
gleichzeitig auch die Flexibilität in Hinblick
auf den Legierungsmix gesteigert. Die neue
Gießgruppe erlaubt es auch, die neuen größeren
Barrenformate für das in Bau befindliche
Warmwalzwerk zu fertigen und ein breites
Legierungsspektrum mit einem hohen Anteil
an wiederverwerteten Schrotten abzudecken.
Der neue Ofen ist kippbar und mit Regenerativbrennern
sowie einer elektromagnetischen
Pumpe ausgestattet. Dadurch kann das
Erschmelzen und Reinigen des Schrotts sowie
das anschließende Gießen des flüssigen Metalls
in einem Aggregat erfolgen. Die Regenerativbrenner
gewährleisten eine optimale
Schmelzleistung bei geringem Energieverbrauch
und stark reduzierten CO 2 -Emissionen.
Die patentierte Brennertechnologie und
die dem Ofen angepasste Anordnung der
Brennerlanzen verhindert zudem die Bildung
von Stickoxiden. Die deutliche Senkung des
Energieverbrauchs gegenüber herkömmlichen
Brennern reduziert Kosten und CO 2 -Emissionen.
Eine zusätzliche Regelung des Gas-Luft-
Verhältnisses in Abhängigkeit vom Restsauerstoffgehalt
im Abgas macht den Energieinhalt
von geringfügigen organischen Schrottverunreinigungen
für den Prozess nutzbar. Dadurch
werden Abgase auf ein Minimum reduziert.
Selbstverständlich wurde mit dem Ofen auch
eine hoch moderne Filteranlage errichtet. Damit
liegen die Emissionswerte des Ofens bezüglich
aller relevanten Schadstoffe weit unter
den gesetzlichen Vorschriften.
Die Ofenanlage besitzt zusätzlich eine elektromagnetische
Rohrpumpe mit Zwischenbehälter,
der seitlich angebracht ist. Dies ermöglicht
neben dem Rühren auch ein effizientes
Auflegieren von Legierungsmetallen bei geringer
Oxidbildung. Ein weiterer Vorteil der
Schmelzehomogenisierung ist die Vermeidung
von Überhitzungen an der Oberfläche (Hot-
Spots) und der verbesserte Wärmeaustausch
innerhalb der Schmelze.
Amag erhält Energiemanagement-
Zertifikat ISO 50001
Seit Mai darf Amag ein besonderes Zertifikat
ausweisen: Als Vorreiter unter den metallerzeugenden
Unternehmen Österreichs erfüllt
Amag die weltweit gültige Norm ISO 50001
für den Bereich Energiemanagement. Die
Zertifizierung erfolgte durch die renommierte

andere Umweltbelastungen reduzieren. Maßgeblich
für die erfolgreiche Zertifizierung der
Amag war die Optimierung der Energiebilanz
in allen Unternehmensteilen. Dabei wurden
neben Energieaspekten auch Umweltfaktoren
wie Wasser, Abfall, Chemikalien und Gebäude-Energiemanagement
berücksichtigt. Ý

lows producing new, larger slab sizes for the
rolling mill under construction and covering a
broad range of alloys with a large proportion
of recycled scrap.
The new furnace can be tilted and is
equipped with regenerative burners and an
electromagnetic pump, so scrap can be melted
and cleaned and the liquid metal be cast in
one unit. The regenerative burners provide
for an optimum melting capacity, while at the
same time minimising power consumption
and CO 2 emissions. Moreover, the patented
burner technology and burner lance arrangement
adjusted to the furnace prevent formation
of nitrogen oxides. The significant reduction
of power consumption compared to
conventional burners results in a reduction of
costs and CO 2 emissions.
The gas-to-air ratio is additionally controlled
as a function of the residual oxygen content
in the waste gas, so the energy content
of minor organic scrap contaminants can be
utilised for the process. Accordingly, waste
gases are minimised. It goes without saying
that a state-of-the-art filter system was installed
together with the furnace. As a result,
the emission values of the furnace with respect
to all of the relevant pollutants are well
below the legal limit values.
The furnace is additionally equipped with
an electromagnetic pump, which is provided
with an intermediate tank mounted at the
side, to enable stirring and efficient alloying
of alloying materials to be performed at a
low oxide formation rate. Another advantage
of melt homogenisation is that hot spots are
avoided and heat exchange in the melt is improved.

Alcoa further extends sheet capacity
Investment addresses North American auto demand
Alcoa has announced its plans for a second
major expansion in North America
to meet what it sees as a growing demand
for light, durable and recyclable aluminium
sheet used in automotive production.
The company is to invest USD275 million over
the next three years to expand and convert
capacity at its rolling mill in Tennessee to
support automotive manufacturers’ plans for
using more aluminium sheet to increase fuel
efficiency, safety, durability and performance
of cars and light trucks. This latest development
follows Alcoa’s previously announced
USD300 million expansion of its Davenport,
Iowa plant due for completion by year-end.
Alcoa claims that the expansion in Tennessee
is a great example of how its edge in technology
and innovation is securing growth opportunities
in its value-added mid- and downstream
businesses. Klaus Kleinfeld, chairman
and chief executive of Alcoa, emphasises:
“More and more auto producers are turning
to aluminium to increase the fuel efficiency
and quality of their vehicles – we anticipate a
quadrupling of auto sheet volume by 2015 and
a tenfold increase by 2025.”
Alcoa’s Tennessee expansion will add 200
full-time, high-value jobs upon completion. In
addition, more than 400 jobs will be created
during the construction phase of the expansion,
welcomed by the state in its continued
growth in the automotive sector. The project
will convert some of the plant’s can sheet
capacity to high-strength automotive production,
as well as installing incremental automotive
capacity. The expansion project is
scheduled to begin shortly and be completed

markets. Alcoa says that a high proportion of
the output planned from the automotive expansion
is already earmarked with long-term
supply agreements.
Mr Kleinfeld points out that this year marks
both the 100 th anniversary of Alcoa’s Tennessee
operations and the company’s 125 th anniversary.
He stresses that there was a very
dedicated and highly engaged workforce in
Tennessee and a very supportive community.
Bonding innovation
The project will incorporate, through Alcoa’s
supply chain, the proprietary ‘Alcoa 951’ pretreatment
bonding technology which enables
adhesive bonding of automotive structures
and is facilitating more cost-effective, mass
production of aluminium-intensive vehicles.
This technology, the company maintains, has
become the new pretreatment bonding standard
for aluminium sheet, extrusion and casting
suppliers across the automotive industry,
and the technology solutions are helping to
drive the continued penetration of aluminium
into the automotive market. Ray Kilmer, executive
vice-president and chief technology
officer of Alcoa, says: “We are enabling not
just increased penetration, but we are working
with OEMs to do it cost effectively in high-volume
automotive applications which, in turn,
necessitates our automotive expansions.”
The use of aluminium in cars is expected
to nearly double by 2025 according to automotive
original equipment manufacturers
(OEMs), and today is already the secondmost-used
material to produce cars. As OEMs
work to continue to make vehicles more
fuel-efficient, many are extending the use of
aluminium from the present array of parts,
such as heat exchangers, wheels, drive shafts,
engine blocks, bonnets
and deck lids, to developing
aluminium-intensive
vehicles (AIVs)
through the conversion
of the body in white, or
body structure, to allaluminium.
However,
the use of aluminium
body structures to improve
fuel efficiency
requires new joining
and assembly methods
and Alcoa 951 offers a
non-chrome solution
for enhancing bond
durability and enables
more cost-effective, mass production of
AIVs.
In customer trials, Alcoa 951 has been
proven to be up to nine times more durable
than titanium-zirconium based applications
formerly used in the automotive industry and
these results encouraged OEMs to specify
Alcoa 951 and request Alcoa to license it to
other suppliers in the industry. The technology,
through an exclusive global distribution
deal, has now been licensed to Chemetall, a
leading global supplier of surface treatments
for automotive components.
Furthermore, Alcoa 951 technology is being
incorporated into the company’s current
automotive expansion projects underway at
Tennessee and Davenport, Iowa Works.
“We look forward to partnering with Chemetall
to provide Alcoa 951 to help enable
commercialisation of adhesive bonding of aluminium
structures in high-volume automotive

aluminium extrusions and die castings

applications. This, in turn, will drive lighter
vehicle weights and enable the integration of
sheet, extrusions and castings to ultimately improve
fuel efficiency,” Mr Kilmer adds.
The process was developed as a result of
collaboration between Alcoa’s automotive
business and the company’s Technical Centre,
the world’s largest light metals research facility,
located near Pittsburgh, PA.
About Alcoa 951 adhesive bonding
Alcoa 951 employs an organic, environmentally-friendly
system tailored for both the aluminium
substrate and the structural adhesives
used for joining. The pre-treatment delivers
far superior bond durability compared to
conversion coating systems such as the titanium-zirconium
widely used in the past. Alcoa
claims that customer trials show 951 bonding
is up to nine times stronger than Ti-Zr surface
treatments.
The surface treatment is applied through an
immersion or spray application in which the
organic components bond with oxides present
on the metal surface. The molecular structure
chemically binds aluminium oxide with one
end, and adhesive with the other. This creates
a strong link at the molecular level resulting
in long-life, durable joints for automotive
structures.
The minimal level of treatment on the surface
makes it essentially ‘transparent’ in downstream
operations in the automotive manufacturing
process, such as forming, resistance spot
welding and painting.
Other commercially available conversion
coatings, which generally contain heavy metals
and are measurably thicker, lead to potential
environmental concerns and diminished
performance in further stages in the manufacturing
process. The attractiveness of Alcoa
951 is essentially centres on its repeatability
and simplicity. It does not incorporate exotic
components that threaten the ability to
implement the product on a large scale, and
it delivers a minimal environmental impact
demanded by the ‘cradle-to-cradle’ life cycle
required for aluminium.
About Chemetall
Chemetall, headquartered in Frankfurt, Germany,
and a division of Rockwood Holdings,
is a leading global supplier of special chemicals,
with some 40 operations worldwide and

Durchschnittlich 60 bis 80 Personen täglich
wurden in der Zeit vom 10. bis 14. Juni in
Kleingruppen durch die Produktionshallen geführt,
wo ein breites Spektrum an Maschinen
und Anlagen vormontiert oder in der Vorinbetriebnahme
mit Material präsentiert und
von Spezialisten an den einzelnen Stationen
vertieft erläutert wurden. Aus dem Bereich
Walzwerkanlagen waren dies zunächst ein
Aluminium-Bandwalzwerk für Bandbreiten
bis 2.150 mm, Eingangsdicken bis 6,5 mm, die
demnächst mit großer Geschwindigkeit bis an
eine Enddicke von 0,15 mm verwalzt werden.
Zusammen mit dem dazugehörigen Feinbandwalzwerk
werden diese Walzwerke künftig
Lithographiebleche höchster Oberflächengüte
produzieren. Neben dieser anspruchsvollen
Walzaufgabe sind die hohen
Coilgewichte von 32 Tonnen,
die das Bandwalzwerk bewältigt,

According to the motto ‘Get in Touch
with Achenbach Technology’, the visitors’
week 2013 took place at Achenbach
in Buschhütten. Guided tours through the
production halls, a wide variety of specialist
presentations and individual customer
support did not only express the
ability to perform, but also the willingness
to perform and the accommodating
service philosophy of the traditional supplier
for first-class rolling mill machinery
and foil slitting machines. The feedback
by the customers was unrestrictedly positive,
which was evident by the quantity of
visitors on the one hand and by their reception
towards the visitors’ programme
on the other hand. Long-term customers
felt vindicated by their supplier selection,
new business relations could be
established and trendsetting investment
projects could be developed.
In the time between 10 th and 14 th June, an
average number of 60 to 80 people per day
was guided through the production halls in
small groups. There, a wide variety of machinery
and systems was presented in
pre-assembled condition or even in precommissioning
stage with material. Specialists
held detailed presentations on the
single stations. The following machinery
was presented: for the rolling mill field,
an aluminium strip rolling mill for strip
widths of up to 2,150 mm, an entry thickness
of up to 6.5 mm, which is to be rolled
to a final thickness of 0.15 mm with high
speed, was presented. Together with the
respective thin-strip rolling mill, these
rolling mills will produce litho sheets of
highest quality in the future. Apart from
this challenging rolling task, the high coil

grated process data recording system must be
emphasised, which is planned to optimise the
OEE (Overall Equipment Efficiency) in the
customers’ production process.
Moreover, two nearly pre-assembled foil
rolling mills for strip widths of 1,700 mm
and 1,850 mm could be inspected by the visitors.
The installation of highly-modern nozzle
valve technology for the coolant distribution
and the use of most modern drive technology
in these rolling mills were special highlights
of this week. Trendsetting media systems,
which are part of the scope of supply such as
Superstack II rolling oil micro-filtration system,
WOR rectification system or – in case of
the foil rolling mill 1,700 mm – an Airpure
exhaust air purification system. These systems
are to purify the rolling mill exhaust air of
this and two other Achenbach rolling mills on
the customer’s premises. The recovered rolling
oil can be redirected to the rolling process in
as-good-as-new quality. The guided tour also
stopped in the Optiroll workshop, where key
components such as the various types of flatness
measuring rolls were presented.
The foil slitting machines also attracted
great attention. Several foil slitting machines
could be presented in pre-commissioning stage
with material. The huge Optifoil Heavyslit,
which is the presently biggest Achenbach-built
roll slitting machine for the aluminium foil industry
having a finish roll weight of 18 tonnes
and a rewinding diameter of 1,800 mm, was
very impressive to the visitors.
Other highly interesting stations on this
guided tour were the Optifoil Varioslit – especially
developed for the processing industry
– for smaller finish roll diameters of up to 800
mm and the Optifoil Jumboslit roll slitting machine
for higher finish roll diameters of up to
1,200 mm. These very universally usable machines
for paper, aluminium, laminates, plastic
and compound foils can be extended by smart
detail solutions, if required.
Another attraction on the guided tour was
the Optifoil Separator in test operation with
material. The separator is part of the Alf Miniplant,
which was developed as compact, experience-based
complete plant for aluminium
foil production and which is highly demanded
especially on the Indian market. In principal,
the Miniplant comprises an aluminium foil
rolling mill, an Optifoil Separator / Slitter, a
roll grinding machine and three annealing
furnaces.
The guided tour through the production
halls was rounded off by a view into the new
production hall, where from now on those
components will be manufactured, which are

neuwertig wieder in Walzprozess einführen
wird. Die Führung machte auch in der Optiroll-Werkstatt
halt, wo Schlüsselkomponenten
wie die unterschiedlichen Typen an Messrollen
gezeigt und erläutert wurden.
Große Aufmerksamkeit zog auch der Bereich
der Folienschneidmaschinen auf sich,
von denen gleich mehrere in der Vorinbetriebnahme
mit Material gezeigt werden konnten.
Besonders eindrucksvoll war allem voran die
riesige Optifoil
Heavyslit,
die mit einem
Fertigrollengewicht
von 18
Tonnen und
einem Wickeldurchmesser
von 1.800 mm
in der Aufwicklung
die
bislang größte
von Achenbach
gebaute
Rollenschneidmaschine
für
die Aluminiumfolienindustrie
darstellt.
Weitere interessante Stationen auf dem
Rundgang zum Thema Schneiden und Wickeln
waren die speziell für den Verarbeitermarkt
entwickelte Optifoil Varioslit für kleinere
Fertigrollendurchmesser bis 800 mm und die
Rollenschneider Optifoil Jumboslit für größere
Fertigrollendurchmesser bis 1.200 mm.
Diese sehr universell einsetzbaren Maschinen
für Papier, Aluminium, Laminate, Kunststoffund
Verbundfolien können zudem bei Bedarf
durch pfiffige Detaillösungen in ihrem Anwendungsbereich
noch erweitert werden.
Anziehungspunkt während der Führung
war nicht zuletzt der Optifoil Separator im
Testlauf mit Material. Er ist Teil einer Achenbach
Alf Miniplant, die als kompakte erfahrungsbasierte
Gesamtanlage zur Aluminiumfolienproduktion
entwickelt wurde und speziell
im indischen Markt auf rege Nachfrage
Optifoil Separator als Teil einer Achenbach Miniplant
Optifoil Separator as part of the Achenbach Miniplant
stößt. Die Miniplant umfasst im Wesentlichen
ein Aluminium-Folienwalzwerk, einen Optifoil
Separator / Slitter, eine Walzenschleifmaschine
und drei Glühöfen.
Abgerundet wurde die Führung durch die
Montagehallen durch einen Blick in die neue
Fertigungshalle, in der von nun an die Fertigung
aller Komponenten, die wesentlich für
die Qualität und Geschwindigkeit der Achenbach-Produktionsanlagen
sind, hergestellt
werden. Die Fertigung wurde dabei nach
einem modernen Materialflusskonzept organisiert
und weiter ausgebaut.
Auf großes Interesse stießen auch die zwölf
technischen Impulsvorträge zu bedeutenden
Weiterentwicklungen, die Achenbach in der
letzten Zeit mit Fokus auf einen möglichst
großen Kundennutzen vorangetrieben hat. Zu
den Themen zählten beispielsweise Ausführungen
zur „Einzelkontaktwalzentechnologie“
oder zu „Model Predictive Control“. Die
je nach Interessenlage individuell zugewiesenen
Vorträge brachten den Fachbesuchern
neue Erkenntnisse und führten zu intensiven
Gesprächen, die beim allabendlichen Get together
im Achenbach-Gästehaus häufig weiter
fortgesetzt wurden.
Zusammenfassend kann man sagen, dass
der integrative Ansatz von Achenbach, Walzwerkanlagen
und Folienschneidmaschinen
zum Aluminiumfolienwalzen, -doppeln, -separieren
und -schneiden gemeinsam zu vertreiben,
mittlerweile weltweit im Markt angekommen
ist: „Alles aus einer Hand“ vor dem
Hintergrund eines Made in Germany, das
nach wie vor weltweit große Strahlkraft besitzt,
zählt zu den Alleinstellungsmerkmalen,
die Achenbach für sich beanspruchen kann.
Immer größer wird zum anderen aber auch

Twelve technical keynote

were of great interest. Two of
the topics presented were Single

foil slitting machines
for doubling, separating

foils has now
arrived on the world
market: ‘Everything
from a single source’
and the well-known
Made in Germany,
still having worldwide
charisma, are
the unique characteristics of Achenbach
Buschhütten. Above that, the demand for
Optifoil slitting machines in the converting
industry is steadily growing, especially, when
slitting of highly sensitive materials such as
very small or big coils to high-class quality
with high productivity is concerned.
In all projects, Achenbach is traditionally
working closely with its customers. Neither in
building rolling mill machinery nor in building
foil slitting machines standard solutions are offered,
but the know-how to turn future concepts
of the customers into tailored machinery
and plant technology. 125 years of experience
in building highly complex plants and machinery
have shown that trendsetting and competitive
projects always need the balance between
both, the solidity of experienced engineering
and the courage to continuously develop ever
more refined solutions.

Kampf Schneid- und Wickeltechnik officially
opened new assembly halls at its
headquarters in Mühlen, Germany, in
mid-July. The executive board of Jagenberg
AG, representatives from politics
and the media as well as suppliers and
employees entrusted with the planning
and implementation of the construction
project accepted the invitation from managing

The expansion of the production area began
in July 2012. In addition to the modernisation
and restoration of the existing buildings, four
new halls with a total usable area of 4,400 m 2 ,
plus 450 m 2 for staff facilities, were constructed.
The crane system has a load capacity of up
to 60 tonnes.
The persistently high number of orders
received by Kampf necessitated the urgent
expansion of capacity. The company had temporarily
hired external assembly space. This
situation led to logistics problems and did not
represent a permanent solution. In his opening

emphasised that
Kampf was oriented
to the future. The
high-tech machines
delivered from the
Mühlen site were
characterised by
highest quality in
terms of performance,
precision,
reliability and longevity
and enjoyed
an excellent reputation
worldwide, he
said. The completed
new production areas
would increase
efficiency.
Further construction
projects
will start this summer.
A new office
building and an additional
hall for customer service will be built
by mid-2014. Furthermore, Kampf intends to
create a new training workshop by the end of
2013. The capital expenditure for the entire
construction project amounts to around 11
million euros in total.
Kampf has been a technology leader in slitting
and winding of various materials for over
90 years. The company employs around 600
people. It has subsidiaries in the US, China
and India as well as international service and

Alumec setzt auf umweltschonenden Korrosionsschutz
Aluminiumvorbehandler macht gute Erfahrungen mit Alodine 5992 von Henkel
Wer morgens gerne eine Dusche nimmt,
hat gute Chancen, dabei in einer Kabine
aus Aluprofilen zu stehen, die von der
italienischen Alumec Srl hergestellt wurden.
Metallvorbehandlungsprodukte von
Henkel helfen dem Unternehmen dabei,
auf umweltschonende Weise perfekten
Korrosionsschutz und zugleich eine exzellente
Optik zu erreichen.
„Die richtige Leichtmetallvorbehandlung ist
zentral für die Qualität eines fertigen Aluminiumprofils“,
sagt Giuolio Marianelli,
verantwortlicher Ingenieur
bei Alumec. Darauf legt man bei
dem im norditalienischen Rudiano
ansässigen Unternehmen großen
Wert. So hat sich Alumec in den
vergangenen 35 Jahren weit über
Italiens Grenzen hinaus hohes
Ansehen als Qualitätsanbieter erworben.
Zu den Kunden gehören bekannte
Hersteller von Duschkabinen,
Fenster und Türen, Produzenten
von Markisen und Jalousetten
aus Alulamellen sowie Architekten,
die mit Alu-Elementen
Fassaden gestalten. Der Großteil
der Produktion geht ins Ausland.
Alumec verfügt über einen eigenen Strangpressbereich,
in dem aus den Aluminium-
Rundbarren die unterschiedlichsten Profile
hergestellt werden. Diese gehen anschließend
gemeinsam mit von Auftragskunden angelieferten
Profilen in die Lackierung, dem zweiten
Produktionstrakt bei Alumec. Rund 20 Tonnen
an Profilen kann das Unternehmen dort
täglich verarbeiten. Mehrere Produkte von
Henkel kommen dabei zum Einsatz, darunter
auch Alodine 5992, das den Konversionsprozess
umweltschonender macht.
Die Vorbehandlung erfolgt in einem speziell
konstruierten schmalen Tunnel, durch
den die hängenden Werkstücke mit einer Geschwindigkeit
von ein bis zwei Metern pro Minute
langsam hindurchgezogen werden. Dabei
fließt kaskadenhaft Flüssigkeit von oben über
die Profile oder sie werden von allen Seiten
mit der jeweiligen Lösung besprüht.
Der Prozess beginnt mit der alkalischen
Entfettung der Profile. Hier kommt Ridoline
2105 von Henkel zum Einsatz. Nach zwei Spülungen
mit Wasser folgt die Behandlung mit
dem ungiftigen Henkel Deoxidizer 1095. Es
folgen zwei weitere Wasserspülungen, bevor

pretreatment products from Henkel help
Die extrudierten Aluminiumprofile werden für die Vorbehandlung vorbereitet
The extruded aluminium profiles are prepared for treatment
Alumec achieve exceptional corrosion
protection results combined with an outstanding
surface finish using environmentally
compatible methods.
“Choosing the right pretreatment is central to
the quality of a finished aluminium profile,”
says Giuolio Marianelli, chief engineer at
Alumec. Quality is something that the company,
located in Rudiano in the north of Italy,
takes particularly seriously. In the last 35
years, Alumec has acquired a notable reputation
well beyond Italy’s borders as a quality
supplier. Its customers include well-known
shower cubicle manufacturers, renowned window
and door producers, makers of marquees,
fly screens and venetian blinds with aluminium
slats, and even architects keen on designing
their facades with aluminium elements.
The majority of the company’s production
goes abroad.
Alumec has its own extrusion facility in
which billets of aluminium alloy are drawn
into a range of profiles. These are then taken
together with extrusions supplied by contract
customers to the conversion and coating department,
the second major production facility
that Alumec operates. The company can finish
around 20 tonnes of profiles there each day,
using a range of Henkel products in the process.
These include Alodine 5992, a conversion
coating product with particularly sound
environmental credentials.
The pretreatment process takes
place in a specially designed, narrow
tunnel through which the
suspended workpieces are slowly
drawn at a speed of between
one and two metres per minute.
The profiles are drenched in the
relevant treatment liquid either
from above in a cascade system or
sprayed from all sides.
The process begins with the
alkaline degreasing of the extrusions,
for which the Henkel product
Ridoline 2105 is used. After
two water rinsing cycles, the treatment
continues with non-toxic
Henkel Deoxidizer 1095. There
then follow two further water rinses before
the workpieces pass through the conversion
section where they are treated with Alodine
5992.

Corrosion protection for powdercoated
and non-coated aluminium
Alodine 5992 is a recent innovation from the
house of Henkel, technology leader in the
field of surface treatment and a company with
a reputation for setting industry-wide standards
with its extensive product portfolio. In
contrast to toxic chromium(VI)-containing
passivation media, the conversion coating
created with this process consists of non-toxic
chromium(III) compounds. In view of the
many statutory regulations governing environmental
protection and occupational health
and safety, Alodine 5992 constitutes a viable
alternative to traditional chromium(VI) conversion
treatments. The trivalent layer offers
bare metal corrosion resistance for uncoated
aluminium surfaces as well as an optimum
keyed surface for any subsequent coating operation.

TECHNOLOGY
“We have been particularly impressed with
the product in terms of its health and safety
benefits, as it means we no longer have to deal
with toxic chromium compounds in our facility,”
affirms Mr Marianelli. The performance
of Alodine 5992 also impresses the Alumec
expert. “We are very happy with the conversion
process, as are our customers,” he says.
Lineguard 2001 as the
pretreatment process controller
At Alumec, the complete aluminium pretreatment
process is monitored and regulated by
the Lineguard 2001 system provided by Henkel.
This fully automatic supervisor ensures
that the product concentration in the tanks is
constantly kept at the right level, saving labour
time and ensuring more precision and reliability
throughout the process. Employees can
take thus care of other tasks, while the problem
of human measurement or replenishment
error is also avoided. And with the Lineguard
2001, operatives are also spared over-frequent
contact with the chemicals.
The last process stage at Alumec – following
yet another rinse operation with demineralised
water and drying of the workpieces – is
that of powder-coating the profiles. Alodine
5992 is Qualicoat-certified and also meets
the MIL Spec requirements for use on the
products in the aircraft industry. As a Qualicoat-certified
company, Alumec is regularly
audited, as required by the associated directive,
to ensure that it continues to satisfy the
specified standards.
The use of Alodine 5992 in the conversion
process prior to the powder-coating operation
also greatly facilitates wastewater treatment
and disposal at Alumec because the
previously required reduction of hexavalent
chromium into the trivalent form is no longer
needed. This is an important aspect for the
company because, in Italy as in many other
countries in the European Union, effluent is
subjected to a strict monitoring regime with
heavy penalties being imposed in the event
of stipulated limit values being exceeded.
Alumec is appreciative not only of Henkel’s
products but also of the service that the
company provides. Customer service managers
travel from Henkel to the plant once a
month on average, with extra visits assured
if problems should arise. However, the Latin
proverb ‘previdet ac providet’ (prevention is
better than cure), which hangs in Marianelli’s
office, is also something to which Alumec’s
technology partners from Henkel are fully
committed.

der Profile. Alodine 5992 ist Qualicoat-zertifiziert
und erfüllt zudem die MIL-
Spec-Anforderungen für den Einsatz in der
Luftfahrtindustrie. Alumec ist ein Qualicoatzertifiziertes
Unternehmen und wird richtlinienkonform
auf die Einhaltung der geforderten
Standards überprüft.
Der Einsatz von Alodine 5992 im Konversionsverfahren
vor der Lackierung erleichtert
auch die Abwasserbehandlung und Entsorgung
bei Alumec, da die Reduktion des sechswertigen
Chroms in die dreiwertige Form entfällt.

TECHNOLOGY
Recycling of wrought aluminium alloys from post-consumed scrap
Part one: Modelling of alternative wrought aluminium alloy compositions for required properties
V. Kevorkijan, Maribor
1. Introduction
The sustainability of wrought aluminium alloys
for demanding structural applications
(e. g. in transportation) is still relatively low.
The prevailing raw materials for their production
are primary aluminium and pure alloying
elements, in combination with internal and
new scrap. For this reason, a significant part
of world production of primary aluminium
is actually consumed for the production of
wrought aluminium alloys. The main technological
reason for that is in the fact that
wrought aluminium alloys are still very difficult
to formulate by recycling post-consumed
aluminium scrap, while the economic reason
lies in the generally higher average cost of
wrought in comparison with cast aluminium
end-products.
The share of wrought aluminium alloys in
world production of aluminium alloys varies
in different parts of world, depending on the
stage of development and the structure of regional
industry. The percentage is higher in
the more developed regions of the world, with
the dominant share from the transport industry.
Similar ratios between wrought and cast
alloys also exist in post-consumed aluminium
scrap collected in different parts of world.
Generally, due to the higher cost of wrought
alloys, aluminium recyclers are always interested
in transforming wrought post-consumed
scrap into new wrought instead of cast alloys.
In the case of internal and also new wrought
aluminium scrap, this is already well practised,
due to the well defined composition of the incoming
materials, which are suitable only for
direct remelting (but not recycled in such a
way so as to be transformed at the end into a
new wrought alloy). However, the precondition
for recycling – the process by which the
virgin metal from post-consumed wrought
aluminium scrap is cycled back into wrought
alloys – is an appropriate level of sorting into
individual compositional streams suitable for
further blending. Here, the existing technical
difficulties in achieving sufficient productivity
and precision in automatic sorting, together
with the high cost of this operation continue
to reduce the amount of wrought post-consumed
scrap recycled back into wrought alloys.
Nowadays, a significant part of post-consumed
wrought aluminium scrap is still consumed for
the production of comparatively cheaper cast
alloys, in that way losing
an important part
of the potentially available
added value.
These trends will
also continue in the
future and, most probably,
even be intensified.
It is reasonable
to expect that with further
reduction in the production of primary
aluminium, its share used for the production
of cast alloys will also be reduced. On the
other hand, due to the long-term projected
higher cost of primary aluminium caused by
the higher cost of energy, the producers of
wrought aluminium alloys will try to replace,
beside existing substitution with internal and
new industrial scrap, the maximum amount
of primary aluminium with post-consumed
wrought aluminium scrap.
Without technological developments toward
increasing the share of post-consumed
scrap in wrought aluminium alloys, one can
expect that in the future most of the technologically
demanding wrought aluminium alloys
would be produced from primary aluminium
in combination with remelting of internal as
well as new industrial scrap. In contrast to this,
most cast alloys will be produced from costbeneficial
post-consumed scrap. This trend,
which is already practised in the aluminium
industry to some extent, could significantly reduce
the sustainability of wrought aluminium
alloys. It restricts the recycling of aluminium
in the true sense of that process (‘re-usage of
post-consumed aluminium in an end product
for the same purpose’), mostly to cast alloys,
while in wrought alloys mostly to remelting of
internal and new industrial scrap.
The main difficulty in recycling wrought
aluminium alloys from post-consumed scrap
is caused by the existing composition of those
alloys, prescribed by international standards
[1]. Currently, on the market there are more
than 200 different compositions of wrought
aluminium alloys divided into eight classes
based on the applied alloying elements. From
the narrow compositional tolerance limits of
alloying elements in practically all wrought
aluminium alloys [1], it is evident that such
chemical compositions could be producible
only by using raw materials of well defined
chemical composition (i. e. alloying elements
Fig. 1: Examples of standard and non-standard tolerance limits with the
relevant denotations used in the model
and primary aluminium of the appropriate
chemical purity, as well as aluminium scrap
streams with carefully prescribed chemical
composition). On the other hand, the presence
of sufficiently narrow compositional tolerance
limits in wrought aluminium alloys is necessary
to provide the proper (standard) combination
of various alloy properties (mechanical,
electrical, chemical, etc.), exactly prescribed
by end users.
Post-consumed aluminium scrap exists in
waste with changeable, non-exact chemical
composition and definitely not as a raw material
fabricated with respect with customer’s
demands. Hence, it is clear that the share of
post-consumed scrap in wrought aluminium
alloys could be increased either by sorting
to fractions with the required chemical composition
and/or by broadening the standard
compositional tolerance limits of alloying
elements. The first solution requires hand
or automatic sorting of post-consumed scrap
as alloys or groups of alloys to the degree of
separation sufficient to enable the blending of
standard compositions of wrought alloys [2,
3]; the second solution is much more radical,
predicting changes in the existing standards
for wrought aluminium alloys toward nonstandard
alloys but yet having properties acceptable
for customers [4]. In this case, the degree
of separation of incoming post-consumed
scrap required is much less demanding.
Nevertheless, to be of interest for customers,
broadening the compositional tolerance
limits of wrought aluminium alloys should
result in alloy properties which are still of
value for end users. In order to tailor the required
(combination and individual values of)
properties in wrought aluminium alloys with
alternative composition, it is necessary to develop
the ability to predict the properties from
a given chemical composition and vice versa –
starting from alloy properties, to predict the
necessary chemical composition of post-con-

sumed scrap streams or, in other words, the
necessary level of scrap sorting. Such prediction
algorithms for wrought aluminium alloys
have been reported by several authors-for a
review see Ref. [5], but are not focused on the
recycling of wrought aluminium alloys from
post-consumed scrap.
Thus, the purpose of this paper is to present
possibilities for numerical modelling 1 of both
technological options for increasing the amount
of post-consumed aluminium scrap in wrought
aluminium alloys. Based on the model developed,
the optimal solution was suggested as
the starting point for further development and
implementation of the appropriate technology
of wrought aluminium alloy recycling.
2. Modelling of wrought aluminium

Table 1: Wrought aluminium alloy compositions considered in the model
Generally, the selected properties of a wrought
aluminium alloy (e. g. yield strength – YS, ultimate
strength – US, elongation – L and hardness
– H) can be all expressed as different
functions of the alloy composition:
YS = F (X 1 , X 2 , X 3 , … , X n ) (1)
US = G(X 1 , X 2 , X 3 , … , X n ) (2)
L = L(X 1 , X 2 , X 3 , … , X n ) (3)
H = H(X 1 , X 2 , X 3 , … , X n ) (4)
Here, X 1 , X 2 , X 3 , … , X n represent the concentrations
of particular alloying elements.
On the other hand, the concentrations of
alloying elements in wrought aluminium alloys,
especially in recycled ones, are most often
designed for achieving maximal strength.
To achieve the proper combination of properties
(not only mechanical but also electrical,
thermal, corrosion resistant, etc.), the concentrations
of alloying elements should be inside
the standard tolerance limits.
However, in wrought compositions containing
an increased amount of scrap, usually
it is not easy and certainly not cost-effective
to assure such narrow compositions. Therefore,
producers of recycled wrought alloys
try to develop so-called ‘recycling friendly’
compositions with broader tolerance limits,
which at the same time do
not significantly influence
the selected (usually some
of the mechanical) properties
of the alloys.
The achievement of
standard wrought alloy
composition by mixing various fractions of
scrap with different chemical composition is
practically impossible. Statistically, in the real
mixture obtained by combining such different
fractions of scrap from the scrap yard, the
concentration of some of the alloying elements
will be higher than those prescribed by
the standard, the concentration of others will
be lower and there will also be some alloying
elements whose concentrations will fit the
standard requirements.
The situation is illustrated in Fig. 1 where
the concentration X 1 of the alloying element
1 in the scrap mixture prepared for melting is
inside the standard interval of concentrations,
the concentration X 2 of the alloying element
2 is higher and the concentration X 3 of the alloying
element 3 is lower. However, all three
concentrations are inside the alternative interval
of concentrations formulated for a ‘recycling
friendly’ composition.
The mathematical condition for ‘recycling
friendly’ alloy compositions under which the
selected alloy properties will all remain the
same is expressed by Eqs.(5) - (8):
dYS = 0 (5)
dUS = 0 (6)
dL = 0 (7)
dH = 0 (8)
In this way, the model developed gives the
combination of non-standard and standard
tolerance limits (∆X i ) under which the selected
alloy’s properties YS, US, A and H remain the
same. The determination of such a combination
of non-standard and standard tolerance
limits (i.e. intervals of concentrations for each
of alloying elements appearing in the alloy)
proceeds in two steps. In the first step, the
intervals ∆X i for alloying elements are determined
by considering each of the properties
individually. After that, in the second step,
the limits obtained for alloying element were
reduced to the intersection of particular intervals,
under which all the selected properties
(YS, US, A and H) are to remain constant simultaneously.
Mathematically speaking, in the first step
we solve the individual equations (5)-(8). Note
that the solution of each of these equations is
the enlistment of the intervals of concentration
(∆X i ). In the second step, the solution of the
system of Eqs. (5)-(8) under which the selected
properties remain constant is obtained as
the intersection of these various intervals obtained
for each particular alloying element.
3. Practical application of the model
Let us consider a wrought alloy with standard
composition and concentrations of alloying
elements inside the tolerance limits, and the
alternative (‘recycling friendly’) alloy with
concentrations of alloying elements slightly
outside the standard tolerance limits (Table 1).
Experimentally available data are collected
in Table 2 where the yield strength (YS) was
measured and correlated with the actual alloy
composition determined by emission spectroscopy.
Let us further assume that the selected alloy
properties (e. g. yield strength – YS, ultimate
strength – US, elongation – L and hardness
– H) are polynomial functions of the alloy
composition.
Note that in each of the equations in the
system of Eqs. (5) - (8), the tolerance limits, ∆X i
(i = 1, 2, 3, … , n) of the individual alloying
elements appear as n independent variables.
Hence, the exact solution of these equations is
not possible. The particular solution of whichever
equations of the system of Eqs. (5) - (8) is,
theoretically speaking, the randomly selected
combination of tolerance limits ∆X i (i = 1, 2,
3, … , n) for which the right hand side of the
equation is equal to zero. However, in the
practical case the values of the tolerance limits
of recycling-friendly wrought aluminium alloy
cannot be selected randomly but should be as
close as possible to the standard ones. Note
that these minimal deviations of each alloying
element from the standard concentrations

composition of

different scrap streams of postconsumed

of the individual scrap streams available in
the scrap yard and involved in creating the incoming
scrap mixture pre-melt composition.
In practice, the system of equations (24) is
applied to numerical modelling of the recycling-friendly
composition, or, in other words,
for selecting the (proper combination of) tolerance
limits, ∆X i (i = 1, 2, 3, … , n), of alloying
elements under which: (i) the selected
mechanical properties of the alloy remain the
same as in the standard one,
and (ii) the chemical composition
of the recycling-friendly
alloy is the same as the premelt
chemical composition of
the incoming scrap mixture
(formulated with the minimal
addition of primary aluminium
and alloying elements).
The main priorities in formulation
of the recyclingfriendly
compositions are:
1. The minimal addition of
primary aluminium and alloying
elements
2. The maximal consumption
of regular scrap streams,
daily available in the scrap yard
3. The non-standard alloy composition for
which the selected mechanical properties remain
the same as in the standard one.
The practical way to do this is by modelling,
starting from the chemical composition of
the scrap streams. The precondition is that the
chemical composition of the recycling-friendly
Fig. 4: Processing steps in modelling the ‘recycling-friendly’ composition for the desired alloy properties
alloy should be the same as the pre-melt composition
of the incoming mixture consisting
of the combination of various scrap streams
with no or minimal addition of primary aluminium
and alloying elements. In addition, the
deviations of the recycling-friendly from the
standard concentrations of alloying elements
should be as small as possible.
In the first step it is necessary to consider
the impact of alloying elements with maximal
deviation of their concentrations from the
standard prescribed. The negative impact of
these elements on alloy properties should be
reduced by minimising the concentration of
others which finally results in the same alloy
properties.
The recycling-friendly compositions of
wrought aluminium alloys should be modelled
in accordance with the following two
criteria: (i) the selected chemical composition
and compositional tolerance limits of a recycling-friendly
wrought aluminium alloy should
fulfil market expectations regarding the alloy
properties; and (ii) the prescribed recyclingfriendly
alloy composition should be routinely
achievable by mixing scrap streams fabricated
in the scrap yard by scrap separation (with or
without minimal addition of primary aluminium
and alloying elements).
In order to achieve these two goals, it is
necessary to define the industrial levels of
wrought aluminium scrap sorting. An example
of the practical levels of sorting of post-consumed
wrought aluminium scrap is presented
in Table 3. Planning the optimal number of
scrap streams, as illustrated in Fig. 2, their
chemical composition and the compositional
tolerance limits of alloying elements for effective
blending of the pre-melting mixture, Fig.
3, with minimal (or even without) addition of
pure alloying elements and primary aluminium
is essential for successful running of the
recycling plant and the final business result.
Therefore, adequate organisation of the
scrap separation streams should provide answers
to the following key questions of scrap
processing:
• How many scrap streams should be
produced by sorting wrought aluminium
wastes in the scrap yard
• How many alloys (just a single one,
a mixture of two or more) should be
involved in these streams
• What should the chemical compositions
be (qualitatively, regarding alloying
elements and also quantitatively,
considering their concentrations as
well as the compositional tolerance
limits) of those streams, and finally
• For which wrought aluminium alloys

A possible way of providing the answers
to the above questions is by calculating the
appropriate composition of the pre-melt mixture
blended from various scrap streams of
different chemical composition, as presented
in Fig. 4.
The model enables: (i) computation of the
recycling-friendly compositions of (wrought)
aluminium alloys based on the known chemical
compositions and compositional tolerance
limits of scrap streams formulated by scrap
sorting in the scrap yard, or (ii) vice versa,
computation of the chemical composition and
compositional tolerance limits of scrap streams
starting from the known composition and tolerance
limits for alloying elements in the selected
aluminium alloy.
The same sorting levels should be applied
to clean and aluminium scrap contaminated
with organics or
other impurities.
Conclusions
The model presented
in this
work enables the
design of optimal
(standard
and non-standard
‘recyclingfriendly’)
compositions and properties of
wrought aluminium alloys with significantly
increased amounts of post-consumed scrap.
The following two routes were modelled in
detail: (i) the blending of standard and nonstandard
compositions of wrought aluminium
alloys starting from post-consumed aluminium
scrap sorted to various degrees simulated
by the model; and (ii) changing the initial
standard composition of wrought aluminium
alloys to non-standard ‘recycling friendly’
ones – with broader concentration tolerance
limits of alloying elements, without influencing
the selected alloy properties, specified in
advance.
The applied algorithms were found to be
very useful in the industrial design of both
procedures: (i) computation of the required
chemical composition of the scrap streams
obtained by sorting (or, in other words, the
post-consumed scrap sorting level), necessary
for achieving the standard wrought alloy composition;
and (ii) transformation of standard
to non-standard (recycling-friendly) compositions
with the key alloy properties (e. g. tensile
strength, elongation) remaining the same.
The most beneficial and particularly promising
approach might be the integral (or combined)
approach, assuring both possibilities:
(i) the standard chemical composition of the
alloy achieved by a sufficient level of post-consumed
scrap sorting predicted by the model,
and (ii) modelling the non-standard alloy
composition by less demanding (and more
cost-effective) sorting, but yet providing end
users with the desired alloy properties.

Quick payback – ecological benefits – small investment
Dryplus process drastically reduces sludge volumes from anodising lines
The patented Dryplus process developed by
Modena-based Italtecno aims to significantly
increase the dry matter in the sludge from aluminium
anodising treatment lines. It enables
dry fractions to be obtained that are equivalent
to 40-50% of the total aluminium hydroxide
sludge instead of the usual 20-25% achieved
in traditional processes.
The environmental benefit of using Dryplus
technology is clearly evident: the sludge
volume is halved and considerably less truck
journeys are needed to transport the sludge.
This results in significant cost advantages
compared with traditional methods (see table).
The Dryplus process consists of a polypropylene
reactor with a volume of 10-15 m 3
that is suitable for use with alkaline solutions,
such as those from the concentrated rinse tank.
The alkalinity is neutralised in the reactor using
concentrates from the Freeal unit as well
as water from the acid rinse.
Aluminium hydroxide is precipitated out
with the help of a special flocculant from Italtecno,
leading to neutralisation of the concentrated
solutions under wellcontrolled
dynamic physical
conditions.
As a result of this treatment,
the aluminium hydroxide
precipitate has a higher sludge disposal

Annual cost of
process: the dry fraction (40- sludge disposal

Dryplus has been successfully

Dryplus can be connected to any existing
waste water treatment plant, which will not
be adversely affected; instead it will be subjected
to less demanding conditions on a dayto-day
basis because the Dryplus technology
will handle the water with the highest impurity

Schwingungen in Walzwerken können sich
negativ auf die Produktivität, die Produktqualität
und die Lebensdauer einzelner Anlagenkomponenten
auswirken. Die Anlage kann
so beeinträchtigt werden, dass Schädigungen
wie Getriebedefekte oder Spindelbruch auftreten.
Insbesondere beim Kaltwalzen nehmen
Schwingungen einen entscheidenden
Einfluss auf die Produktqualität in Form von
Chatter-Marks (Rattermarken) – das sind
quer zur Walzrichtung meist periodisch verlaufende
Wellen auf der Bandoberfläche im
µm-Bereich. Die Folgen sind eindeutig: Das
Endprodukt ist von minderer Qualität oder
Ausschuss, die Walzgeschwindigkeiten müssen
in einen schwingungsfreien Bereich reduziert
werden und Stillstandszeiten nehmen
zu. Problematisch sind diese Effekte vor dem
Hintergrund steigender Qualitätsansprüche
und der Tendenz zu immer höherer Produktivität
in Walzwerken.
Die Anforderungen an die Anlagen bezüglich
Zuverlässigkeit, Lebensdauer und
Prozessstabilität sind enorm gestiegen. Die
Betriebssicherheit der Anlagen lässt sich am

herstellen. Der international tätige
Konzern Novelis mit Hauptsitz in Atlanta,

In rolling mills, numerous vibrations with
diverse results can appear. These might
have negative effects on the life cycle and
the condition of the plant as well as on
product quality. Anyway, it is necessary
to know exactly the vibration behaviour
of the own plant for being able to monitor
appropriately wear and tear as well as
defects. The aluminium producer Novelis,
knows about the negative effects of vibrations
and uses the new Condition Monitoring
system by iba AG for evaluation
and invention.
Vibrations in rolling mills can have a negative
effect on productivity, product quality and
service life of single machine components.
The plant can be adversely affected in a way
that damages like gearbox defects or breakings
of the spindle might occur. Especially during
cold rolling, the vibrations exert a decisive
influence on product quality in the form of
the so-called chatter marks. Chatter marks are
waves on the strip surface in the µm range
that run horizontally to the rolling direction,
mostly periodically. The consequences are
clear: The end product is of inferior quality
or even waste, the rolling speeds have to be
reduced to a vibration-free range and plant
downtimes are increasing. These effects are especially
problematic considering the growing
quality standards and the trends towards an
ever higher productivity in rolling mills.
The demands on the machines regarding
reliability, service life and process stability
have been growing enormously. The operational
safety of the plants can be established
best using process- and condition monitoring.
The globally operating group Novelis, with its
headquarters in Atlanta, produces at 31 locations
on four continents almost 20 percent of
the rolled aluminium products world-wide.
For consolidating this position, the company
continuously optimises its production processes,
the capacity utilisation and the productivity.
Monitoring the machine vibrations in coldrolling
mills in a data-based and conditionrelated
manner, deriving diagnoses from
these data and intervening with appropriate
measures are one element of this objective.
Novelis wants to reach that goal with the

TECHNOLOGIE
Ein Element dieser Zielsetzung ist, die Maschinenschwingungen
an den Kaltwalzanlagen
datenbasiert und zustandsbezogen zu
überwachen, daraus Diagnosen abzuleiten
und mit entsprechenden Maßnahmen zu intervenieren.
Dies will Novelis mit dem Condition-Monitoring-System
„ibalnSpectra factory“
erreichen, das als Pilotprojekt in den
Anlagen im Werk Nachterstedt für online basiertes
Chatter-Monitoring installiert ist.
Zwei Features in einem System vereint
Am Standort Nachterstedt in Sachsen-Anhalt
hatte Novelis schon länger ein Schwingungsmesssystem
in Betrieb. Da dieses über eine
separate Auswertung lief, konnten die Prozessdaten
aus der Anlage nicht zusammen
mit den Schwingungsdaten ausgewertet werden.
Um die Schwingungen beim Walzen nicht
nur zu erkennen, sondern gleichzeitig aus den
erfassten Daten Defekte zu diagnostizieren,
Kennwerttrends zu analysieren und daraus
Maßnahmen für die Instandhaltung und Prozessoptimierung
zu generieren, tauschte Novelis
das bisherige Schwingungsmesssystem
gegen ein System der iba AG aus. „In den Gerüsten
hatten wir zur Prozessanalyse sowieso
das Prozess-Daten-Aufzeichnungssystem
ibaPDA eingesetzt. Deshalb war es sinnvoll,
das ibalnSpectra als zusätzliches Add-On
dieses Systems für das Chatter-Monitoring zu
nutzen“, erklärt Robert Krumbach, Leiter des
Kaltwalzwerks in Nachterstedt bei der Novelis
Deutschland GmbH.
Das ibalnSpectra ist ein neuartiges Condition-Monitoring-System,
das die erfassten
Signale nicht nur unter Maßgabe von Condition-Monitoring-Vorgaben
auswertet, sondern
auch alle anderen relevanten Betriebsparameter
nutzt. Nur mit dem iba-System kann die
Überwachung von Condition Monitoring relevanten
Daten bei gleichzeitiger Prozessüberwachung
mit allen Maschinen-, Prozess-, Material-
und Qualitätsdaten realisiert werden.
Die iba AG bietet das lnSpectra in variabler
Skalierung für verschiedene Anwendungsszenarien
an. Für die Überwachung im Kontext
einer komplexen Anlage wie bei Novelis ist
„ibalnSpectra factory“ die geeignete Lösung.
Mit ihr lassen sich die relevanten Rohdaten für
das Condition Monitoring und die Prozessüberwachung
fertigungsweit und produktionsübergreifend
erfassen.
Zudem lässt sich ibalnSpectra herstellerneutral
in jedes gängige Automatisierungssystem
integrieren. In dieser Konnektivität der
Condition-Monitoring-Module sieht das Kaltwalzwerk
von Novelis einen weiteren wichtigen
Vorteil des CM-Systems. Das Projekt in
Nachterstedt startete im Februar 2012, seit
Anfang dieses Jahres ist das Chatter-Monitoring
nun in Betrieb. Wenn sich das Pilotprojekt
in Nachterstedt als praktikabel erweist, plant
Novelis ibalnSpectra konzernweit zur Anwendung
zu bringen. Die Konnektivität der
iba-Module ist Voraussetzung, um in einem
Konzern wie Novelis mit rund 30 Produktionsstandorten
weltweit eine Gesamtoptimierung
vorzunehmen.
Schwingungen mit Abtastrate
bis zu 100 kHz erkennen
Kaltwalzanlagen verfügen über ein komplexes
Schwingungsverhalten ausgehend von Eigenschwingungen
der Anlagenmechanik über
Anregungen aus den Getrieben oder Lagern
bis hin zu Anregungen durch Defekte oder
Drehzahlveränderungen. Während des Walzens
können sich Schwingungsanregungen
unterschiedlicher Entstehungsmechanismen
und Frequenzen überlagern und sich gegenseitig
verstärken. Prozessbedingt sind Schwingungen
bei neuen wie auch alten Anlagen
nicht zu verhindern. Vielmehr geht es darum,
sie mithilfe geeigneter Methoden so zu überwachen,
dass Schäden jeglicher Art vermieden
werden.
Bei Novelis in Nachterstedt hat man die
Erfahrung gemacht, dass Gerüstschwingungen
in Abhängigkeit vom Belastungszustand unterschiedlich
zu beurteilen sind: „Beim Kaltwalzen
wird das Coil an unseren Gerüsten
bis auf eine Geschwindigkeit von bis zu 1.250
Meter pro Minute beschleunigt. Während
der Beschleunigungsphase registrieren wir
verschiedene Schwingungszustände mit unterschiedlichen
Auswirkungen auf die Anlage
und das Produkt“, erklärt Krumbach. Die
Walzen werden in sogenannten Einbaustücken
gelagert. Die Schwingungen, die unter
anderem über die Einbaustücke initiiert werden,
übertragen sich sofort auf das Gerüst.
Deshalb hat Novelis an den Einbaustücken
der beiden Walzgerüste Beschleunigungssensoren
angebracht, die das Schwingungsverhalten
überwachen und damit Aufschluss über
das Schwingungsverhalten des kompletten
Gerüsts geben. Der Walzwerksleiter erläutert:
„Die Einbaustücke verfügen über eine
Eigenfrequenz im Niederfrequenzbereich.
Sie schwingen bei Anregung also sehr langsam.
Wenn aus den niederfrequenten Schwingungen
hochfrequente werden, können wir
zum Beispiel auf Fremderregung schließen.“
Um die Ursache für die Fremdschwingungen
ermitteln zu können, bedarf es einer genauen
Kenntnis der Schwingungsfrequenzen
aller Elemente im Gerüst. Die AuswerteeinibalnSpectra

system, which has been installed in the machines
as pilot project in the Nachterstedt plant
in Saxony-Anhalt, Germany, for online based

Two features united in one system
At the Novelis Nachterstedt plant, a vibration
measurement system has been in operation
for a longer time. As this measurement system
ran over a separate analysis, the process
data from the plant could not be analysed together
with the vibration data. For not only
detecting the vibrations in the rolling process
but also diagnosing defects from the acquired
data, analysing trends of characteristic values
and generating from these values measures for
maintenance and process optimisation, Novelis
replaced the existing vibration measurement
system by a system from iba AG. „In the rolling
stands, we used the ibaPDA process data
recording system, anyway. For this reason, it
made sense to use ibalnSpectra as add-on for
this system for chatter monitoring“, explains
Robert Krumbach, manager of the Nachterstedt
cold-rolling mill at Novelis Germany.
ibalnSpectra is an innovative Condition
Monitoring system which does not only evaluate
the acquired signals regarding the Condition
Monitoring guidelines but also uses all
the other relevant operating parameters. Only
the iba system allows monitoring the data
relevant for Condition Monitoring and simultaneously
monitoring the processes with all
machine, process, material and quality data.
iba AG offers lnSpectra in variable scaling
for diverse application scenarios. For monitoring
in the context of a complex plant, like
the Novelis plant, ibalnSpectra Factory is the
appropriate solution. With this solution, the
relevant raw data for Condition Monitoring
and process monitoring can be acquired in a
production-wide manner.
Moreover, ibalnspectra can co-operate with
every common automation system, independent
of the manufacturer. The staff of the Novelis
cold-rolling mill considers this connectivity
of the Condition Monitoring modules to
be another important advantage of the CM
system. The Nachterstedt project started in
February 2012 and since the beginning of
this year, the chatter monitoring has been in
operation. In case the Nachterstedt project
proves to be successful, Novelis will introduce
ibalnSpectra across the whole company. The
connectivity of the iba modules is the prerequisite
for making an overall optimisation in a
company like Novelis with about 30 production
sites world-wide.

Detecting vibrations with a
sampling rate of up to 100 kHz
Cold rolling mills show a complex vibration
behaviour, beginning with natural vibrations
of the system mechanics, over excitations
coming from the gearboxes or bearings up to
the excitations originating from defects or
varying speeds. In course of the rolling process,
the vibration excitations originating from
diverse mechanisms and frequencies can superimpose
and mutually reinforce. Due to the
process, the vibrations cannot be prevented
neither in new nor in old systems. It is rather
a question of monitoring the vibrations using
Aluminium coils at Novelis
appropriate methods and hence preventing
any damages.
At the Novelis Nachterstedt plant, experience
has shown that the vibrations of the
roll stands need to be evaluated differently
depending on the load: “In the cold rolling
process the coil on our roll stand is accelerated
up to a speed of 1,250 m/min. During the
acceleration phase, we are noticing different
vibration states which exert different effects
on the machines and the product,“ explains
Mr Krumbach. The rolls are stored in the
so-called chocks. The vibrations that are initiated
among other things by the chocks, are
immediately transferred to the roll stands.
This is why Novelis has mounted acceleration
sensors on the chocks of the two roll stands,
which are monitoring the vibration behaviour

bezüglich der Signalanzahl angeboten.
Zur Verfügung stehen Lizenzen für 64 bis
2.048 Signale sowie für eine unbegrenzte
Anzahl Signale. Für die normale Messdatenerfassung
stehen Zeitbasen von 1 bis 1.000
ms zur Auswahl. Für höhere Signaländerungsgeschwindigkeiten
können auch kürzere Erfassungsraten
bis zu 10 μs realisiert werden.
Ist ein Bauteil beschädigt, verursacht dieses
Schwingungen in einem bestimmten Frequenzband.
Die von der Auswerteeinheit erfassten
Zusatzschwingungen können auf Basis
dieser Werte konkreten Bauteilen zugeordnet
werden. Ist beispielsweise ein Kugellager mechanisch
defekt, verursacht es hochfrequente
Zusatzschwingungen von 1.200 Hz. Ab diesem
Frequenzband deuten die Schwingungen
zum Beispiel auf Lagerschäden hin.
Komplexes Schwingungsverhalten
online überwachen
Eine erfolgreiche Zuordnung der Maschinenschwingungen
ist möglich, wenn die Condition-Monitoring-Daten
und Prozessdaten miteinander
in Echtzeit in Verbindung gebracht
werden können. Dank des ibalnSpectra ist
es bei Novelis Nachterstedt erstmals möglich,
Daten wie Geschwindigkeit, Walzkraft,
Drehmomente, Temperatur und Walzöldruck
online mit den Schwingungsdaten zu korrelieren.
Um die Schwingungen positiv beeinflussen
und sie minimieren zu können, kann
Novelis die Einflussgrößen auf das Schwingungsverhalten
mit dem ibaInSpectra auch
online variieren. Dazu werden die Messdaten
mit dem ibaQPanel auf dem Steuerstand der
Leittechnik in Echtzeit visualisiert. Zusätzlich
können Alarmmeldungen generiert werden,
die entweder eine automatische Anpassung
der Walzengeschwindigkeit auslösen oder
eine manuelle Einstellung anstoßen. Bevor das
Chatter-Monitoring-System von iba eingesetzt
wurde, gab es keinen exakten Rückschluss auf
Ursachen für die entstehenden Schwingungszustände
des Kaltwalzgerüstes.
Die Analysemöglichkeiten des ibalnSpectra
reichen von einfachen Kennwertbildungen
aus den Zeitsignalen wie Minimum, Maximum
oder RMS-Wert bis zu komplexen
Auswertungen im Frequenzbereich wie Amplitudenspektren,

and hence provide information on the vibration
behaviour of the whole roll stand. The
manager of the rolling mill explains: „The
chocks have a natural frequency in the low
frequency range. Hence, when being excited,
they show a very slow vibration. When low
frequency vibrations become high frequency
vibrations, we can conclude that we are dealing
with external excitation.”
For being able to determine the external
vibrations, the staff needs to know exactly
the vibration frequencies of all elements in
the roll stand. The evaluation unit of the CM
system – the ibaPDA-V6 measurement value
acquisition system – acquires all sensors with a
sampling rate of up to 100 kHz time synchronously,
continuously and scaled to physical
units. ibaPDA-V6 is offered in several variants
regarding the number of signals. Licenses for
64 to 2,048 signals as well as for an unlimited
number of signals are available. For the
normal measurement data acquisition, there
are time bases of 1 to 1,000 ms available. For
higher speeds of signal changes, also shorter
acquisition rates of up to 10 μs can be realised.
In case a machine component is damaged, it
causes vibrations of a certain frequency band.
The additional vibrations that are acquired
by the evaluation unit, can be clearly assigned
– on the basis of these values – to certain
components. If e.g. a ball bearing is mechanically
defective, it causes additional high frequency
vibrations of 1,200 Hz. Within this
frequency band, the vibrations imply defective
bearings.
Online monitoring of
complex vibration behaviours
The machine vibrations can be assigned successfully,
if the Condition Monitoring data
and the process data can be related to each
other in real time. Due to ibalnSpectra it is
possible at the Novelis Nachterstedt plant to
establish online correlations between data
like speed, rolling force, torque, temperature,
rolling oil pressure on the one hand and vibration
data on the other. For being able to
exert a positive influence on the vibrations
and thus minimising them, Novelis can – using
ibalnSpectra – also adjust the influencing
variables on the vibration behaviour online
during the process. For that purpose, the
measurement data are visualised by means of
ibaQPanel in the control pulpit in real time.
Moreover, alarm messages can be generated
which either trigger an automatic adaptation
of the rolling speed or initiate a manual adjustment.
Before the implementation of the
chatter monitoring system, no exact conclusions
could be drawn concerning the causes
for the vibration conditions of the cold rolling
mill.
The analysis options of ibalnSpectra range
from simple parameter calculations from time
signals like minimum, maximum or RMS values
to complex evaluations in the frequency
range like amplitude spectra, envelope curve
spectra or Cepstrum analysis. Frequency spectra
can be calculated using the Fast Fourier
Transformation (FFT). Also statistical parameters
can be calculated. Using drag & drop,
the parameterised analysis object can be used
in the visualisation. Significant values of all
machine-, process-, material- and quality data
can be extracted to a database. Flexible and
efficient analysis tools allow for the early
detection of significant correlations between
these data. For the cross-plant analysis of the
measurement data it is an advantage that the
devices of the lnSpectra product lines can be
operated autonomously, but also that the data
can be transferred to a central evaluation unit
via diverse network interfaces.
Only by combining different measures in
an online based chatter monitoring system
that includes the process optimisation and
plant monitoring, the operators of a rolling
mill come as close as possible to their ideal
of reliable and fault-free products. Together,
iba AG and Novelis Nachterstedt have taken
a significant step forward in this matter.

Alufer’s Bel Air project in
Guinea hit by licensing delays
Junior bauxite producer Alufer Mining has
delayed construction of its Bel Air bauxite
project in Guinea by a year, due to licensing
delays. Construction is now predicted to start
in 2014, with product shipment expected in
2016. The delay at Bel Air stems from the
Guinea government’s steps to tie mining licenses
to their revised mining code. Alufer
submitted its licence application in October
2012, but Guinean authorities could not issue
the licence before concluding amendments to
the September 2011 mining code.
The junior miner has lined up financiers
and suppliers for Bel Air, and one of the deals
involves China’s Hongfan Industries, which
has agreed to a 5m tpy bauxite offtake arrangement
and to a prepayment arrangement
to help Bel Air into commercial production
within 24 months. Hongfan will buy half of
the planned production from Bel Air and will
pre-finance mine development.
Bel Air requires a USD310m capital outlay,
the bulk of which is targeted for supporting
infrastructure.
Hydro issues force majeure notice
due to power outages at Alunorte
Hydro issued a notice of force majeure to its
alumina customers as power outages and lowered
production at Alunorte alumina refinery
may affect alumina deliveries to customers.
On 18 May the refinery experienced a blackout
in its electrical power supply system due
to unexpected external events. As a consequence,
Alunorte suffered a partial electrical
power outage. On 2 June, while in the process
of stabilising and resuming production, Alunorte
experienced another, shorter black-out
caused by an unrelated external event. These
events caused serious disruption so that the
refinery has not been able to resume full production
of alumina.
Alunorte production levels will be lower
in the second quarter than in the first, and are
expected to remain unsatisfactory also for the
rest of the year. As a measure, Hydro has established
a team of experts aiming to stabilise
and increase production at the refinery.
Alunorte is the world’s largest alumina
refinery, with a nameplate capacity of 6.3m

Logan Aluminum rewarded
for energy efficiency efforts
Logan Aluminum in Russellville, Kentucky,
is saving electricity and money on its power
bills at its production facility through energy
efficiency efforts in partnership with the Tennessee
Valley Authority. The manufacturer
of flat rolled aluminium sheet, primarily for
beverage cans, refitted its lighting systems
and upgraded equipment including pumps and
air dryers through the EnergyRight Solutions
for Industry Programme offered by TVA and
Russellville Electric Plant Board. The projects
reduced the mill’s annual power consumption
by more than 2m kWh, which is enough energy
to supply about 150 homes in the Russellville
district for a year. The energy savings
also earned the company a cash incentive of
USD182,400 from TVA.
TVA’s EnergyRight Solutions for Industry
offers 10 cents per kWh on first-year savings
or 70% of project cost, whichever is less, to
programme participants for approved energy
efficiency projects. “Energy efficiency helps
keep rates low, reduces costs associated with
meeting consumer demand, conserves natural
resources and produces zero emissions,” said
Brent Powell, one of the managers of the TVA
energy savings programme in Kentucky.

LOI wins order for coil annealing
line by Ma’aden-Alcoa
Tenova LOI Thermprocess has been awarded
a contract for the installation of a heat treat-
70 ALUMINIUM · 7-8/2013

COMPANY NEWS WORLDWIDE
© Tenova LOI Thermprocess
ment line for aluminium strip coils for the
Ma’aden-Alcoa facility in Saudi-Arabia. The
line consists of single-coil lifting hearth furnaces
which allow the individual heat treatment
of coils. The installation is scheduled for
2013.
This heat treatment line allows adapted
heat treatment according to the specific needs
of the individual strip within short time, instead
of heat treatment in a batch of several
coils, which would require an average heat
treatment or the combination of a batch of
identical strip coils. The heat treatment and
cooling can be processed in protective atmosphere.
The system works fully automatically
from taking the coil out of the storage area
until the heat treated coil is placed into the
storage area again.
The special plant and furnace design has
been invented in 1998 by LOI Thermprocess
and has been installed first at Alcan Singen,
Germany. To date LOI has installed more than
fifty units.
Seco/Warwick Allied supplies
soaking pit furnaces to Hindalco
Seco/Warwick Allied has recently installed
seven soaking pit furnaces at Hindalco Industries
in Hirakud in eastern India. The furnaces
feature side-mounted fans, which improve
maintenance access, and a combination of fan
and heater arrangements to produce separate
control zones along the vertical length of the
slabs as well as a patented adjustable baffle
design. The furnaces are designed for vertical
loaded slabs to process can body stock.
Each furnace is designed for a maximum load
of 128 tonnes. The overall charge height is
five metres maximum and 3.5 metres minimum
from eight to 16 slabs per batch. An
adjustable baffle has been provided for
proper air circulation in the event shorter slab
heights are loaded. The furnace is designed
for electrical heating with individual self-propelled
lid (cover) trolley mechanism, and is
equipped with PLC-based control and monitoring
system.
New Otto Junker induction heater
for Hydro Aluminium Nenzing
Otto Junker has received an order from Hydro
Aluminium Nenzing for another induction-type
heater including log storage and log
handling equipment. More than 30 years ago,
Otto Junker supplied one of the world’s first
induction-type aluminium log heaters with a
downstream hot shear to Hydro’s Nenzing
works. In 2007, this system was upgraded to
3,600 kW by adding an Otto Junker-supplied
IGBT converter system; as a result, it now attains
a throughput of nearly 80 billets per hour.
The consistently positive experience gathered
with this plant prompted Hydro Aluminium
Nenzing to opt for an Otto Junker furnace
system of nearly identical design when a new
investment decision came up.
The system comprises a feed table with
chain conveyor, a vertical log magazine for
up to 60 logs, a feed conveyor, and an induction
furnace measuring around five metres
in length in which the logs are heated to a desired
temperature profile before being cut to
length in the existing hot shear prior to entering
the press.
Logs are delivered to the chain-type log
magazine by forklift truck and are stored and
managed according to alloy type. On the feed
conveyor, the length of each log is accurately
measured for the required ‘odd end’ optimisation
process. Heating is carried out in a multilayer
low-loss induction coil which, like in
the existing heater, consists of six individually
controlled coil sections.
The billet heating operation relies on an
IGBT converter system developed by Otto
Junker. This converter system is based on
transistor technology and offers the advantage
of steplessly adjustable power control in addition
to high efficiency and low maintenance
needs. Designed by Otto Junker around ten
years ago, the technology has since proven its
merits in over 170 billet heating and induction
melting furnace applications.
Mechatherm modernises
Dubal’s casting pit DC1
Mechatherm had been awarded an order to
completely rebuild Dubal’s casting pit DC1.
The contract involved significant mechanical,
hydraulic, electrical and combustion work to
three furnaces and to a vertical aluminium billet
casting machine. It required considerable
demolition followed by civil work organised
by Dubal. Only then could the new equipment
be installed and commissioned with a complete
new Mechatherm software automation
system. Work was projected to take twelve
weeks, during which the casting pit would be
shut down completely, with no production.
Due to the excellent collaboration with Dubal
engineers, Mechatherm and its sub-contractors
managed to complete the work and get
the pit into production in less than eight weeks.
Thus Dubal could cast over 5,000 tonnes of
extrusion billet above their predicted output.
