Reduction of lead times by 25 to 50 percent<br />
Elval live with Quintiq Company Planner<br />
Elval S.A., the sole Greek<br />
producer of rolled aluminium<br />
products, has gone live<br />
with the Quintiq Company<br />
Planner since April. To optimise<br />
the supply chain, the<br />
company is implementing<br />
an ambitious programme<br />
using also Quintiq’s Hot<br />
Mill, Cold Mill, Foil, Melt-<br />
Cast Schedulers and Routing<br />
Generator. Elval’s aim:<br />
to maximise capacity utilisation,<br />
to reduce inventory<br />
and to improve delivery<br />
performance. Elval uses as<br />
a backbone SAP, entirely<br />
integrated with the Quintiq<br />
solution.<br />
Elval produces aluminium<br />
foil for flexible packaging, lacquered<br />
can-end stock, coated<br />
aluminium strip for building<br />
and construction applications,<br />
as well as special magnesium<br />
alloys for shipbuilding,<br />
automotive and printing.<br />
In such a diverse production<br />
environment, world class<br />
planning and scheduling is<br />
an important success factor to<br />
maximize the performance of<br />
the plant.<br />
The processing of rolled<br />
aluminium products requires<br />
planning of various production<br />
flows, such as casting,<br />
hot- and cold-rolling as well<br />
Siemens supplies<br />
reversing rolling mill<br />
to China<br />
Chalco North East Light<br />
Alloy Company Ltd, a subsidiary<br />
of Chinalco, has<br />
ordered a single-pass reversing<br />
finishing mill with twin<br />
coiler from Siemens VAI<br />
Metals Technologies. The<br />
project is part of a hot and<br />
cold mill expansion which<br />
will be erected in Harbin.<br />
The order is worth some 13<br />
million euros and includes<br />
key electrical and mechanical<br />
components together<br />
with the automation and<br />
process technology. The<br />
new rolling mill is scheduled<br />
to start production<br />
in August 2011.<br />
Chalco North East Light<br />
Alloy (Chalco Nela), based<br />
in Harbin in the northern<br />
Chinese province of Heilongjiang,<br />
produces plate and<br />
sheet, strip, foil, tube and pipe<br />
from aluminium, magnesium<br />
and Al-Mg alloys. The<br />
company’s products are used<br />
mainly in aviation, transport<br />
and communication as well<br />
as the electronics and lighting<br />
industry. The new reversing<br />
mill will increase Chalco<br />
Nela’s strip production capacity<br />
by 210,000 tonnes per year<br />
and allow production of end<br />
products of increased hardness<br />
and reduced thickness at<br />
enhanced quality levels. The<br />
plant has been designed for<br />
rolling strip with a width of<br />
up to 2,100 millimeters at a<br />
speed of up to 363 meters per<br />
minute.<br />
The finishing mill comprises<br />
a 4-high stand with<br />
automatic hydraulic gauge<br />
control as well as positive and<br />
negative work roll bending.<br />
Siroll ISV Sprays are used for<br />
spray cooling. In addition to<br />
the mechanical equipment,<br />
Siemens will be supplying the<br />
entire automation system and<br />
the drive technology for the<br />
rolling mill as well as thickness<br />
and profile measurement<br />
systems and the sensor<br />
technology. The automation<br />
system embraces the basic<br />
automation, including the<br />
technological controllers and<br />
the operating and monitoring<br />
equipment.<br />
The scope of supply also<br />
includes the process automation<br />
equipment for the entire<br />
hot strip mill, which also<br />
comprises a reversing roughing<br />
mill to be supplied by a<br />
local vendor. This degree of<br />
system compatibility ensures<br />
a consistently high product<br />
quality. All the systems and<br />
components belong to the<br />
‘Siroll Alu’ integrated solution<br />
platform from Siemens for<br />
aluminium rolling mills. Siemens<br />
will also be responsible<br />
for commissioning the plant<br />
and training the customer’s<br />
personnel.<br />
Siemens to supply<br />
Siroll oiler to Alcoa<br />
Samara<br />
Siemens VAI Metals Technologies<br />
has received an order<br />
to supply a Siroll electrostatic<br />
oiler for a slitting line at the<br />
Alcoa Samara plant in Russia.<br />
This is the first Siroll oiler sold<br />
into Russia by Siemens VAI.<br />
The Siroll electrostatic<br />
oiler is designed to provide<br />
automated, non-contact,<br />
non-pressurized, protective<br />
or lubricating coatings (oil,<br />
wax or chemicals) to moving<br />
metal substrates, in strip<br />
or sheet form, accurately<br />
and effectively. The result is<br />
improved end product quality<br />
with reduced wastage and<br />
increased yield. Alcoa’s plant<br />
in Samara is Russia’s largest<br />
producer of fabricated aluminium.<br />
The plant is one of<br />
the two producing facilities of<br />
Alcoa Russia that combined<br />
hold about 50% of the domestic<br />
mill products market.<br />
Alcoa acquired its facilities in<br />
Russia in 2005 and has since<br />
invested about USD750 million<br />
for their total upgrade.<br />
