EDITORIAL
In the past year the Indian as well as global
economy has witnessed a very high degree of
uncertainty and volatility. The Indian Sponge Iron
Industry also felt the cascading effects of
economic slowdown, however the industry feels
squeezed, but with its fundamentals still intact it
has the strength to utilize its full potential and
grow at double-digit rates when backed by the
Government in terms of raw material inputs. The
key growth drivers being infrastructure
development and high level urbanization,
escalating demand from housing, automobile, white goods and rural/
agricultural development sectors.
There has been tremendous amount of Government response and
support to the Industry, which is helping to bring out possible easing of
the situation and also showing clear signs of recovery. But obviously
this road is long and improvement is going to be gradual.
To achieve the production target of 124 Million Tons, for growth the
steel Industry has to heavily depend on the secondary route, using
Sponge Iron as a major source of quality metallics. However the DRI
Industry is facing serious problems, which need special considerations
from the Government to ensure short term and long-term supply of
vital raw materials namely Coal, Iron Ore and Natural Gas at affordable
prices. The economic crisis has led to the review or cancellation of
many planned investments in capacity expansion. This may result in
imbalance between capacity and demand levels unless corrective
measures are taken now. The Sponge Iron Industry is fully geared up
for the future but policy initiatives from the Government on availability
and prices of raw materials have become a pressing need of the
manufacturers’. We are confident about help for our sunrise Industry
and await all steps with optimism.
The robust growth of SIMA from 10 members in 1999 to 102 members
in 2009 can be attributed to its commitment and sincere efforts to serve
its members. The driving force behind SIMA has been encouragement
& co-operation of the members, which has made SIMA a very successful
result oriented Association at both National and International levels.
Your participation in Industry activities is our strength.

CHAIRMAN’S MESSAGE
As India takes stride towards industrialization, it
encounters many problems at the foundation level.
Conflict between the industries and local agro
based population over land acquisition and water
allocation which sometimes precipitates explosive
situation reveals incoherence between the vision
of the policy makers and perception of the people
at the grass root level.
Issue of water allocation stems from plummeting
level of ground water which sometimes becomes
alarming due to weak or delayed monsoon and
poses a threat to survival both for agriculture and
industries of the region. Proposal to connect the
rivers is a pragmatic solution and should be
supplemented by clearing the silt deposit and
deepening of the river bed with spillways and dams.
This can also be utilized as waterways to ameliorate
the logistic problem that is coming to surface as
we start our journey.
Human resource requirement for tomorrow needs
serious concern today. The process of Human
resource development is slow but more important
than capital formation or infrastructure. It requires
joint effort of industries and government to plan out
future requirement in order to prevent starvation of
competent personnel in future. Industries should
also have constant interaction with educational
institutions.
Government must encourage
and support green field
ventures in the field of power,
steel and allied industries which
would provide foundation for the
superstructure
of
industrialization. Allocation of
mineral blocks for the captive
use of the industries deserves more attention than
what it receives today.
Industries on their part have a sacred duty to
conserve raw material and learn to live in an
environment of scarcity. It has taken million of years
for nature to create the minerals and these are
meant for many generations. Abundance of raw
material does not give us a liberty to take the cream
and leave the waste for our successors. We must
utilize the waste in effective manner. The countries
which have achieved industrialization under raw
material scarcity have developed innovative
technology for utilization of waste and we must
learn and adopt the same into our process.
India had for long accepted agriculture as the main
fabric of economy. Now large scale industrialization
would create a happy and balanced economy for
the country and it is just a bend ahead.

PRODUCTION OF SPONGE IRON THROUGH TUNNEL KILN PROCESS
S.S. Bedarkar
Electrotherm (India) Limited
Direct reduction includes the processes in which iron
ore (lumps/ pellets) is reduced in the solid state and
oxygen is removed by either solid or gaseous
reducing agents. The reductants used are noncoking
coal or natural gas. The product is used in
steel making and melted in a manner similar to the
scrap. For gas based processes shaft furnaces,
fluidized bed retorts, etc. are used while for coal
based processes rotary kiln based plants are very
popular.
Tunnel kiln process:
Hoganas has developed a retort based process in
1908, which uses coal as a reductant. The
carbothermic reduction of iron ore takes place in
horizontal tunnel kiln.
Reduction mix, consisting of coal or coke fines of
the size 3 mm or below, anthracite, and limestone, is
charged with iron ore in ceramic muffles/saggers.
Ceramic saggers give life of about 8-10 heats. For
better life (about 100-120 heats) and improved heat
transfer, many plants use silicon carbide (SiC)
saggers. The materials are arranged in alternate
layers in the form of concentric rings within a sagger.
Figure 1 depicts the sagger with iron ore and coal in
a concentric manner. Also, in some processes
alternate layers of coal-ore-coal are placed.
Coal
Iron ore fines
Figure 2 shows unfilled SiC saggers. Individual
saggers are then stacked on one above the other.
Arrays of such units are formed above the kiln car.
Schematic of the arrangement of the saggers above
the car is shown in Figure 3 (a). Figure 3(b) depicts
the actual photograph of car trolley along with array
of saggers. The plant in which silicon carbide
saggers are used, the empty saggers are first
placed one above the other, and then the concentric
feeding of coal and iron ore fines is carried out.

mounted on trolley, entering into tunnel kiln
The cars are then pushed through the tunnel kilns.
Figure 4 shows the photograph of car pushing
system. The time between two cars entering the kiln
is called the “pushing time”. The tunnel kiln consists
of three zones; the preheating zone, the reduction
zone, and the cooling zone. Schematic of the tunnel
kiln used by Hoganas is depicted in Figure 5 . The
kiln cars first travel through the preheating zone,
then through the reduction zone, where the ore is
reduced into iron at a constant high temperature of
1100-1200 °C. The kiln cars are then cooled in the
cooling zone of the kiln. It takes approximately 28-
36 hours for a kiln car to travel through a kiln. The
time of travel may vary from plant to plant. The
combustion air flows in the opposite direction of the
kiln cars. Cold fresh air first cools the hot cars and
after passing through the reduction zone, hot exhaust
gases preheat the incoming cars before the gases
exit the kilns. Because of concentric feeling of raw
material inside the sagger, the coal ash and sponge
iron, a product, remain separate inside the sagger.
The product, thus formed, can be separated easily.
Figure 6 shows the sponge iron in the form of a
cylinder.
Figure 5 Schematic of the tunnel kiln
The efficiency of the Hoganas sponge iron process
is defined as the energy needed for the reduction
reactions compared to the energy added to the
system. Eriksson and Larsson [1] presented the
Sankey diagram for heat balance for the process is
shown in Figure 7. From the diagram it could be
observed that large amount of heat demand for the
process is fulfilled by coke mix and natural gas, while
the maximum heat is consumed by the reduction
reactions. The process efficiency of Hoganas
process is about 40 %, which decreases slightly with
decreased pushing time.
Figure 6 The product of tunnel kiln
SEPTEMBER-2009/3
Consumption of raw materials and energy per tonne
of sponge iron for Hoganas process is as follows
[2]:
Iron ore concentrates : 1350 kg
Coke : 500 kg
Lime : 125-130 kg
Energy consumption : 14.5 GJ
Typical analysis (%) of Hoganas sponge iron is,
Fe (metallic) : 93.0
Fe (total) : 97.0
Metallization : 95.9
C : 0.2
S : 0.008
P : 0.012
Gangue : 1.6
The consumption norms will vary as per the quality
of input raw materials. Instead of coke if coal is used
then the quantity will further increase. With Chinese/
anthracite coal the consumption is about 0.9 to 1.1
tonnes per tonne of sponge iron. With Indian coal,
the consumption is expected to be more. Out of the
total coal, 60 % will be utilized for iron ore reduction
and the remaining 40% will be used to produce coal
gas.
In China, Tangshan Outstanding Kiln Co., Ltd. has
installed a tunnel kiln for sponge iron production.
The factory has tunnel kiln of 260 m in length and
2.78 m in width with a single annual production
capacity of 50,000 – 70,000 T of direct reduced iron.
The capacity of the current factory is 100,000 T per
year. The kiln car has size of 3.4m x 2.6m. Above
the car, an array of 6x8 saggers has been formed.
Each column contains about 5 saggers. As a product
each cylinder of sponge iron weighs about 90 kg.
As per design, maximum operating temperature is
1220 °C.
Looking at the overall scenario of tunnel kiln process
it can be said that tunnel kiln process is capable of
reducing iron ore fines using coal / coke fines.
Consumption of the coal per tonne of production of
sponge iron is considered as coal required for
reduction and coal required to generate coal gas.
With thorough study of fluid dynamics and proper
circulation of the coal gas and hot air within the kiln
helps in improving the thermal efficiency of the kiln.

COAL-BASED DRI SOLUTION FOR INDIAN IRONMAKING
Rob Cheeley, Sales Manager, Midrex Technologies, Inc., USA
Introduction
As one of the world’s most vibrant and growing
economies, India has a strong steel demand for
infrastructure, construction, and consumer goods.
From 1998-2008, its steel demand grew at nine
percent per year. To feed this demand, steel
production has grown from less than 10 million tons
(Mt) in 1980 to over 55 Mt in 2008, as shown in
Figure 1.
Figure 1
India Steel and DRI Production
Sources: WorldSteel and Midrex Technologies
There are ambitious plans to increase the country’s
steel production, with the Indian government having
set a goal of 110 Mt by 2020(?).
Approximately 58 percent of India’s steel is currently
produced in electric furnaces. Given the lack of
domestic scrap and the good availability of natural
resources like iron ore, coal and natural gas, direct
reduction has provided much of the iron units
required for Electric Arc Furnace (EAF) steel
production growth. Direct Reduced Iron (DRI)
production has increased tremendously since 1980,
from essentially zero to over 21 Mt in 2008, as shown
in Figure 1. Of the total DRI production in 2008, 74
percent was produced from coal and 26 percent from
natural gas. India is now the world’s largest producer
of DRI.
Currently, there are two primary means of DRI
production in India: small-scale rotary kilns using
local coal and iron ore lump, and large-scale shaft
furnace plants using natural gas and iron oxide
pellets and lump. In recent years, almost all the
growth in DRI production has been due to the
installation of rotary kiln facilities and there are now
over 350 of these plants. Many are small-scale and
it is believed that over 100 have capacities from
10,000-20,000 tpy. There are only seven natural
gas-fired shaft furnace plants (including six MIDREX®
Direct Reduction Modules), but they produce 1/4 of
the total DRI in India.
Future Steelmaking Growth
For India to grow its steel production significantly,
what are the options? Direct reduction using coalfired
rotary kilns or natural gas-fired shaft furnaces
are logical choices. Rotary kiln DRI capacity has
been installed because it makes use of domestic
iron ore and coal, but there is a limit to the growth of
this technology because rotary kilns cannot be built
larger than about 200,000 tpy. Thus, it is probably
not feasible to build a steel mill to produce one million
tons per year or more via this route. Also, there are
product quality issues because of the use of lump
ore and coal with high levels of ash and sulfur. Direct
reduction plants using natural gas would be an ideal
choice, but there is little additional natural gas
available for further expansion.
Another possibility is the installation of conventional
blast furnace/basic oxygen furnace technology, but
this requires the importation of coking coal or coke,
since only about five percent of India’s coal reserves
are coking quality. Also, there may be environmental
issues and the capital cost can be high.
The Gasification/MIDREX® Option
An alternative option generating significant interest
in India is the use of a coal gasification plant in
combination with a MIDREX® Direct Reduction Plant.
SEPTEMBER-2009/5
The coal gasification plant would use local Indian
coals to generate a synthesis gas (or syngas) that
can be an acceptable reducing gas source for
producing DRI in the MIDREX Plant.
Coal Gasification
There are three general types of coal gasifiers: fixed
bed, entrained flow, and fluidized bed. All three
technologies are based on partial oxidation
(gasification) of a carbonaceous (carbon containing)
feed material.
The general partial oxidation reaction is:
2 CHn + O
2
———> 2 CO + n H
2
In addition to the desired CO and H 2 , the syngas
exiting a gasifier also contains CO 2 , H 2 O, CH 4 , H 2 S,
and particulates. If a fixed bed gasification
technology is utilized, the syngas will also contain
ammonia and aromatic organic compounds.
While each of the gasifier types can make an
acceptable reducing gas for a MIDREX DR Plant,
the fixed bed technology is the preferred choice for
India because it can accommodate the high ash
domestic coals. The leading fixed bed process is
the Lurgi Gasification process, licensed by Lurgi
Clean Coal Technology Company. The Lurgi
Gasification technology is well-proven, with over 102
gasifiers in commercial operation worldwide, the
earliest of these built in 1955. Eighty of these units
are deployed in South Africa, using high ash coals
very similar to Indian coals.
Lurgi Coal Gasification Process
In the Lurgi Gasification process, coal is gasified at
elevated pressures by reacting with high pressure
steam and high purity oxygen to produce a syngas
suitable for the production of fuels and chemicals.
The gasifier operates at a temperature below the
ash melting point so the coal ash is discharged from
the gasifier as a solid. Because of this low operating
temperature, the Lurgi Gasification process requires
significantly lower quantities of oxygen than the
entrained flow gasification processes which melt the
ash.
The syngas exiting the gasifier is hot, dirty, and
contains a significant amount of non reducing gas
components. Downstream of the gasifier, the syngas
is cleaned and conditioned to remove most of the
undesired components, many of which are saleable
byproducts that can be used as petrochemical plant
feedstocks.
Figure 2 contains a simplified process flowsheet for
combining the Lurgi Coal Gasification technology
with a MIDREX Plant and Figure 3 shows Lurgi
gasifiers at the Sasol Plant in Secunda, South Africa.

The following table summarizes the major
characteristics of the Lurgi Gasification Plant.

Produces valuable and l Phenols
saleable co-products
l Ammonia
l Coal oil
l Elemental sulfur
l Low pressure (L.P.) steam
MIDREX® Direct Reduction Plant
The high pressure syngas exiting the Lurgi
gasification plant contains approximately 85 percent
H 2
+CO, 2.5 percent CO 2
, and 12.5 percent CH 4
. The
H 2
/CO ratio is about 1.6, which is the same as used
in a natural gas-based MIDREX Plant.
In the MIDREX Plant, the cold syngas is first
depressurized to about 3 barg. If the syngas flowrate
is high enough, it may be economical to use a turbine
generator to depressurize the syngas.
The low pressure syngas is then mixed with recycled
gas to produce the required reducing gas. The mixed
syngas is then heated to over 900º C. The hot
reducing gas enters the MIDREX® Shaft Furnace
where it reacts with the iron oxide to produce DRI.
The reduction reactions are shown below:
Fe 2
O 3
+ 3H 2
—> 2Fe + 3H 2
O
Fe 2
O 3
+ 3CO —> 2Fe + 3CO 2
The spent reducing gas (top gas) exiting the shaft
furnace is scrubbed and cooled, then passed
through a CO 2
removal system. This reduces the
CO 2
content to five percent or less, which ensures
that the mixed reducing gas (syngas from the
gasification plant and recycled top gas from the
MIDREX Plant) has an acceptably high reductants
(H 2
+CO) to oxidants (H 2
O+CO 2
) ratio for efficient iron
oxide reduction. The CO 2
removal system will also
remove the sulfur gases contained in the recycled
top gas.
DRI Hot Transport Options
The DRI can be discharged from the MIDREX Shaft
Furnace at temperatures up to 700º C. Many of the
newer MIDREX Plants are designed to transport the
hot DRI to a nearby electric arc furnace to take
advantage of the available sensible heat.
Depending on the distance from the MIDREX Plant
to the steel mill, there are different options for hot
DRI transport. The following identifies which hot
transport option is recommended:
SEPTEMBER-2009/7
Distance between
Shaft Furnace and EAF
Hot Transport Mode
0 – 40 meters HOTLINK®
40 – 200 meters Hot Transport Conveyor
or Hot Transport Vessels
> 200 meters Hot Transport Vessels
HOTLINK:
The HOTLINK Process primarily uses
gravity to feed DRI from the MIDREX
Shaft Furnace into storage bins
located directly above the EAF. This
hot transport mode requires the
bottom of the MIDREX Shaft Furnace
to be at a higher elevation than the
EAF. The HOTLINK Process is under
construction at ESISCO in Egypt and
at Shadeed in Oman.
Hot Transport The hot transport conveyor option
Conveyor: continuously transports HDRI from
the discharge of the MIDREX Shaft
Furnace via an inclined bucket
conveyor into storage bins located
directly above the EAF. For this hot
transport mode, the MIDREX Shaft
Furnace discharge can be at a
significantly lower elevation than the
EAF. This hot transport mode is
operating at Hadeed Module E in
Saudi Arabia.
Hot Transport In the hot transport vessel option,
Vessel: the HDRI exiting the MIDREX Shaft
Furnace is discharged into
refractory-lined containers. These
containers are then transported by
truck or rail to the steel mill. At the
steel mill, a crane is used to lift the
containers above the EAF so that
the HDRI can be discharged directly
into the EAF. The hot transport
vessel approach has been used by
Essar Steel since 1998 and is
operating at the Lion Group plant in
Malaysia.
Figure 4 below shows the Hot Transport Conveyor
option that is utilized at HADEED Module E. On the
left side of this picture is the melt shop, on the right
side of this picture is the MIDREX® Shaft Furnace,
and between them is the inclined Hot Transport
Conveyor.
Figure 4
Hot Transport Conveyor at HADEED Module E
MIDREX® Plant Capacities
MIDREX Plants can be designed and built for a wide
range of DRI capacities. Midrex is currently
designing modules with capacities ranging from
400,000 t/y up to 2,200,000 t/y.
Forty-five operating MIDREX® Direct Reduction
Modules have rated capacities between 400,000 t/y
and 800,000 t/y (six more are under construction),
seven operating MIDREX Modules have rated
capacities between 1,000,000 t/y and 1,400,000 t/y
(one more is under construction), and five operating
MIDREX Modules have rated capacities of 1,500,000
t/y or higher (three more are under construction).
Hadeed Module E is the largest MIDREX Plant, with
a rated capacity of 1,760,000 t/y and has been
operating since 2007. This Module uses the Hot
Transport Conveyor concept to deliver hot DRI at >
600º C into the EAF.

DEVELOPING AND IMPLEMENTATION OF SAFETY CULTURE
R Somnath & Suresh Thawani
Tata Sponge Iron Limited, Joda
Abstract
Safety is becoming an increasingly important subject
for the management of all industrial organizations.
The concern, depending upon the value system of
the organization, spans from valuing human life at
one end to just compliance to regulations at the
other end. In all the cases, however the organizations
get benefit of higher productivity depending upon
their belief in safety value system.
This paper endeavors to create an approach to
develop and implement a general safety culture in
organisations, to the benefit of its employees & the
management.
Even though special emphasis has given to the
unorganised sectors at large, this paper also throws
light on safety needs and processes in large
organisations. Objective of this paper is to highlight
two general components of safety culture: a
framework in the organisations to be co-created by
management & workmen and a constructive attitude
of the workforce at all levels for positive acceptance
of all safety norms.
Introduction
The April 1986 disaster at the Chernobyl nuclear
power plant[1] in Ukraine was the product of grave
lapses committed by the plant operators in the
context of a system where training was abysmally
low. Investigations attributed the human negligence
to the absence of a safety culture resulting out of a
direct consequence of Cold War isolation.
The immediate cause/s of accidents are often
associated with human error or technical snag.
However the investigation & analysis of the
circumstances surrounding major accidents such as
the one above, or Three Mile Island, Kings Cross,
Clapham, etc. have revealed issues beyond such
immediate causes. A quotation from an enquiry
reports illustrate the point : “their belief in safety was
a mirage, their systems inadequate, and operator
errors commonplace
…. from the top to
bottom, the body
corporate was
infected with the
disease of
sloppiness.”
It is now a known
fact that the basic
faults
in
organisational
systems, climate and
procedures may Chernobyl reactor #4 after the
disaster, showing the extensive
predispose an
damage to the main reactor hall
organisation to an (image center) and turbine building
accident. This
(lower left)
backdrop scenario is
being increasingly described from the context of
safety culture, where culture comprises the attitudes,
beliefs and behaviours that are generally shared
within the organisation. The International Nuclear
Safety Advisory Group (INSAG) termed ‘safety
culture’ for the first time in 1988 in its summary report
on the Post-Accident Review Meeting on Chernobyl
Accident.
Since then, a number of definitions of safety culture
have been introduced. The U.K. Health and Safety
Commission developed one of the most commonly
used definitions of safety culture, which describes
safety culture as: “The product of individual and
group values, attitudes, perceptions, competencies,
and patterns of behaviour that determine the
commitment to, and the style and proficiency of, an
organization’s health and safety management”.
“Organizations with a positive safety culture are
characterized by communications founded on mutual
trust, by shared perceptions of the importance of
safety and by confidence in the efficacy of preventive
measures.”
Thus, safety culture can be described as an
SEPTEMBER-2009/12
environmental setting where everyone feels
responsible for safety and pursues it on a daily basis,
going beyond ‘the call of duty’ to identify unsafe
conditions and behaviors, and intervene to correct
them. In a safety culture, safety is not a priority that
can be shifted depending on situational demands,
rather it is a value linked with all other situational
priorities.
Implementing a safety culture
Over the past 50 years, organisations have primarily
focused on successfully improving the technical
aspects in their plant & machinery to improve safety,
as is evident from lower accident rates caused due
to machine failures. However, with the frequency of
technical failures diminishing in industry, the role of
human behaviour has become more perceptible.
Safety experts estimate that 80–90% of all industrial
accidents are attributable to human factors and
organisational priorities [2] over safety. It is now
widely accepted that the general likelihood of an
accident occurring depends not just on the actions
of individual employees but on the safety culture of
the organisation[3].
A positive safety culture entails that the whole is
always more than the sum of the parts. From various
studies, it is clear that certain factors appear to
characterize organisations with a positive safety
culture, which are typically as follows :
v
v
v
v
commitment by Senior Leadership
Clarity of expectations from the line managers
Involvement of all employees
Commonly understood & agreed goals through
effective communications
v
v
v
Good organisational learning & agility to change
practices/behaviour
Focused alertness on workplace safety
Encouraging good safety practices through
rewards & recognitions
Improving safety culture must be regarded as a
systematic & continuous process. This ideally
undergoes the PDCA cycle through initial
assessment of the existing safety culture,
determining priorities for change, develop action
plans to effect the desired changes and then
regularly reviewing progress before repeating its
cyclicity.
Broadly, there are four components to implementing
an effective safety culture :
1. Establish safety as a core value : The
importance of safety to the individual, the
organization and the community should be
understood by everyone directly or indirectly
involved with the organization. Each individual
should have an awareness of his/her
responsibilities with respect to their safety
performance. The culture should reflect a strong
individual and group intolerance for violations
of safety norms. There should be a balanced
perspective on the importance of both traditional
worker safety and process safety performance
as unique but parallel goals of the organization.
2. Commitment from the top : In order for the
workforce to become safety conscious,
commitment from the senior leadership is
indispensable. Ability & motivation of the line
managers with day to day responsibility for safety
is proportional to the commitment from top
management, which lays the foundation for the
sustenance of safety culture. It is necessary for
senior management to realize the true costs of
accidents which go far beyond injuries to persons
or loss of productivity. To the outside world, it
also implies a lack of reliability & lackluster
attitude of the company as a unit. Sensitiveness
to safety often graduates in fostering the culture
through rewards & recognition and other means.
SEPTEMBER-2009/13
3. Measuring the scale of the problems :
Crucial to achieving a genuine safety culture is
having the means to monitor the company’s
current performance in order to identify ways in
which safety can be continuously improved.
Across all industries, the most widely used form
of monitoring the effectiveness of current
policies is the near miss accidents (Fuguais)
which, if not attended, escalates to lost time
accidents. This is more appropriately depicted
through the Heinrich safety triangle below which
emphasises to concentrate on the fundamentals
that eliminate the behaviours that cause the near
misses.
Researchers have concluded that reduction in
the number of personal accidents is directly
proportional to the number of other accidents,
involving damage to properties. The goal of a
true safety culture therefore is to reduce the near
miss rates to zero. There are other means of
monitoring safety performance which may
include categorization of injury types, or following
typical formats arising out of statutory reporting
requirements contained in industrial safety
norms. The key point, however, is that companies
must employ some regular means of monitoring
their safety performances.
4. Changing Bahaviour : It is often quoted that,
“safety culture is how we behave when no one
is watching.” The key aspect of a safety culture
is changing the behavior of its workforce so they
believe in safety, think safety and consistently
look for further improvements.
Introduction of a genuine safety culture based
on the concept of continual improvement,
personal commitment and responsibility on the
part of everyone in the company, is a long term
process and involves dedication & hard work.
To a certain extent, practicing the laid down
safety regulations through Safety Management
Systems result in certain change in behavior.
However, companies can take additional steps
to encourage the change from a culture of
compliance with regulations to that of a culture
based on individual commitment to safety.
At one extreme, companies may wish to conduct
detailed behavioural assessment programme,
hiring expert services, in order to work out the
best way to move forward. The assistance of
outside consultants may then be used to oversee
the change in the company’s safety culture.
However, this would largely depending on the
size of workforce and for many companies, a
less ambitious approach may be more
appropriate.
A three-stage model[2] developed by an offshore
operating company explains different stages of
employee attitudes & behavioural pattern (see
diagram). This model is useful as organisations
can identify their current stage and identify
actions to move them to the next stage. The
three stages in this model are, (a) dependent,
(b) Independent; & (c) Interdependent.
SEPTEMBER-2009/14
While this model describes the safety culture
improvement process in three separate stages, it is
likely that different parts of an organisation are at
different levels at any one time. It will therefore be
important for organisations to diagnose the stage
that different parts of the organisation are at, before
attempting to improve the safety culture.
Stages of development of safety culture
National policies are a necessity to boost the
development and implementation of safety and
security in the organisations, particularly in small &
unorganised sectors. Management and technical
staff responsibilities in these organisations usually
are not clearly defined. Highly skilled professionals
or technicians are the exception, and in general the
technical staff would only have the necessary
knowledge to deal with their work. These
organisations do not facilitate training & periodical
retraining of their staff, and a policy to disseminate
information on safety issues is either non-existent
or does not feature in the list of priorities.
Understanding of safety culture and self diagnosis
of its stage of development may be difficult in their
environment of economical urgencies, small number
of employees and other adverse constraints.
Professional associations should help such
organisations in their understanding of safety issues,
and should provide an appropriate environment for
“horizontal” communications between them.
The following classification of stages of development
of safety culture in unorganised sectors is
descriptive and not rigid. At any time, organisations
they may exhibit a combination of the following main
characteristics of the stages.
Stage I -
Stage II -
Stage III -
Safety issues are not fully addressed by
the organisation.
Safety issues are addressed mainly to
comply with regulations or as a formality.
Good safety performance becomes an
organisational & individual goal.
The suggestions in Table-I[4] are examples of some
actions aimed at assisting small & unorganised
organisations in their progress toward higher stages
of development of safety culture.
I to II
II to III
Require support from other organisations (professional associations, regulators) to review
or formulate safety policy, and communicate that action to the staff
establish safety training of the managerial level and the staff.
facilitate employees participation in the activities of professional associations
introduce regular review of safety and seek for employee’s suggestions in order to identify
areas of improvement, with emphasis on safety and security of spent sources
make employees aware of safety issues as part of quality performance.
make employees aware of strategic goals that relate quality and safety to long-term profits
make employees aware of other organisations who have successfully improved their safety
performance, to demonstrate that achievement is possible
Review safety performance and make employees aware that safety is not only a technical
issue. Promote a questioning attitude to prevent the problem of orphan sources
Facilitate cross communications with similar organisations and start collaborative work with
regulators
Table I - Suggestions to assist progress toward safety culture
SEPTEMBER-2009/15
Errors as a learning opportunity
Employees at small & unorganised sectors should
be encouraged to report human errors during
operations. Senior management should promote
employee participation in professional boards and
interactions with ‘safety cultured’ organisations to
confer and experience their unique practices.
Special emphasis should be given on cognitive
mechanisms as they determine the extent to which
questioning attitude is retained during operations.
Self learning & experience promote the automotive
controls to such an extent that they no longer require
conscious control.
Role of the regulatory body
The Regulatory Body should conduct a review of
the factors in the overall corporate culture that may
have significant influence in the development and
implementation of safety culture, and should
promote programs aimed at assisting unorganised
organisations in the cultural transformation of their
management. Their roles can be better described
as below[5] :
v
v
v
Provide a model of how an organisation should
approach the development of an effective safety
culture
Provide a means by which an organisation’s
current approach to developing its safety culture
can be assessed
Provide a means by which improvements in an
organisation’s approach to developing its safety
culture can be identified.
v Encourage industries to conduct safety climate
surveys and application of behavioural safety
standards.
Conclusion
Achievement of an effective safety culture is a
prerequisite to implementing and maintaining
satisfactory standards of safety performances. The
indirect costs of industrial accidents are estimated
to be around 3 times the direct costs associated
with injuries & loss of lives and damage to properties.
As such, depending upon the level of its existence,
safety culture can prove to be a threat or competitive
advantage for organisational sustenance.
Safety culture is commonly described as the values
& practices that management and workforce share
to ensure that safety is always the first priority, thus
moving beyond statutory compliance to a culture of
self regulation.
Implementing an effective safety culture has four
broad components which primarily address the
softer aspects of safety management than
ordinance. Therefore, improvement in safety culture
is a continuous process, involving everyone in the
industry.
The Regulatory Bodies should play a pivotal role
promoting safety culture through customized
programmes & review mechanisms at unorganised
sectors in particular, and should go beyond
restricting itself to merely ensuring conformance to
regulatory norms.

MAGNETITE THE FUTURE GLOBAL IRON ORE IN STEEL INDUSTRY
The global iron ore industry is on the verge a major
transformation, driven by a combination of booming
global demand and diminishing stocks of high-grade
ore.
World consumption of iron ore is driven by the global
steel industry and grows on average by 10% per
annum, with the main consumers being China, Japan,
Korea, the United States and the European Union.
The major producers of iron ore include China,
Brazil, Australia, India, and Russia.
The major growth constraints for the global iron ore
industry are:
• the position of the iron ore relative to market;
• the cost of rail infrastructure to get it to market
• the energy cost required.
The growth in demand for iron ore over the past
decade has principally been driven by the Chinese
economy. During the first half of this decade, China’s
steel consumption grew at a rate of 1.5-2.5 times
GDP driven by rapid industrialization and
urbanization.
The principal ore minerals of Iron are Heamatite &
Magnetite.
Hematite (Fe O )
2 3
Traditionally, the Global Iron ore industry has been
based on the mining, production and export of highgrade
hematite ores which currently account for
approximately 70% of global iron ore production.
High-grade hematite is often referred to as “Direct
Shipping Ore” or “DSO” because it is mined and
beneficiated using a relatively simple crushing and
screening process before being exported for use in
steel mills.
Magnetite (Fe O )
3 4
Magnetite ore has lower iron content and must be
upgraded to make it suitable for steelmaking.
Magnetite ore is suitable for processing into iron ore
pellets for use in modern steel production and
currently accounts for approximately 30% of global

iron ore production. The magnetic properties of
magnetite enable it to be readily refined into an iron
ore concentrate.
While magnetite is generally a lower-grade
deposit, it is globally accepted as a viable and
high-quality feedstock for the production of
premium quality, low impurity steel.
Magnetite – the Future of Global Iron Ore…
Traditionally, Haematitic “iron ore” with DSO quality,
is considered as emergence of the world’s great iron
deposits. As a result, magnetite has been greatly
misunderstood and undervalued by the market.
Because it has lower iron content than hematite, has
been regarded as a less attractive proposition.
However, the availability of cheaper energy combined
with unprecedented global iron ore and steel demand
is changing this perspective.
Magnetite projects today are capable of
producing high-quality concentrate grading up
to 68-69% Fe, which is higher grade than many
of the hematite lump and fines ores currently
being produced.
The processing route for magnetite requires primary
crushing, secondary crushing, screening, primary
grinding, fine grinding, magnetic separation, flotation,
thickening, filtering and drying. The final product is
a high iron grade magnetite concentrate (+65% Fe),
with typically very low impurities. Further processing
involves the agglomeration and thermal treatment
of the concentrate to produce pellets, which can be
used directly in a blast furnace or direct reduction
steel-making plant. The attached flow diagram (Fig
-1) is an overview of magnetite process from the
physical mining activity to the end user.
The additional processing cost for the
production of magnetite concentrate can be
offset by the premium price which it attracts
from steel mills because of the high iron
content compared to benchmark DSO hematite
products.
SEPTEMBER-2009/17
Magnetite projects today are capable of producing
high-quality concentrate grading up to 68-69% Fe,
which is higher grade than many of the hematite
lump and fines ores currently being produced. Also,
it is well established that hematite grades are
declining globally and impurity levels are rising while
the demand or quality, premium steel from China
and India is continuing to increase.
With hematite grades declining, high-grade
magnetite concentrate is becoming an increasingly
sought-after product. Steel mills are now buying
increasing volumes of high-grade, low impurity
magnetite concentrate to supplement declining
supplies of high-grade lump ore, in order to maintain
the quality of their final product.

Exploration and Quality of Magnetite Deposits:
Today’s in the modern world the New Magnetometer
locator of higher sensitivity & sharp measurement is
used for prospecting of Magnetite Ore deposits. The
speciality of this instrument is that it directs towards
the centre of even small commercially processable
ore bodies through concentrating & amplifying the
signal from the ore body both at the INPUT and
OUTPUT of the Sensor. Simultaneously the methods
of quantitative geochemical prospecting is being
carried out which allow to cut the costs (as much as
50 %) of locating iron ores in conventional drilling
method. The main advantages of the new
magnetometer and the geochemical method are as
follows.
1. The possibility, before expensive drilling, of
determining the coordinates of principal ore
bodies both in the horizontal plane & in depth
by the new patented magnetometers with
elevated sensitivity & sharp measurement
directivity as well as of yielding an estimated
forecast of the ore reserves.
2. As a result by putting a single borehole in the
centre of the location, the quantative estimation
of the ore deposit would be evaluated in stead
of putting dozens of boreholes.
Quality :
For Magnetite Deposits, to be viable, the ideal quality
parameters should be as follows.
SEPTEMBER-2009/18
Fe % - > 41 %
SiO2 % - 30 to 36 %
Al2O3 - up to 1.0
P % - 0.09 to 0.10
S % - 0.03 to 0.07
Major Constraints in Magnetite Mining & Processing:
1. The mining & processing of magnetite involves
the consumption of a significantly higher amount
of electricity.
2. The emission intensity of CO2 will be more (i.e.
800 to 1000 parts per million) which is the
greatest environmental pollution. So a proper
design of the Carbon Pollution Reduction
scheme is required and to be approved by the
government of the respective country.
Conclusion :
Hence it can be concluded that, the magnetite ore
is definitely going to be major raw material in the
future global steel industry.

TENOVA – OFFERING A BROAD RANGE OF TECHNOLOGIES FOR
THE INDIAN MARKET
Thomas M. Scarnati
Manager Marketing & Sales, Tenova HYL, Mexico
Perhaps some readers are not yet familiar with the
relatively new name of Tenova, but they are steadily
making their presence known both in India and
worldwide.
Tenova, formerly known as Techint Technologies, is
a world-wide supplier of advanced technologies,
products and services for the metal and mining
industries providing innovative integrated solutions.
Combined process automation and metallurgical
know-how enhance the value delivered to the
customers. Tenova is committed further to develop
its technology in the areas that mostly impact the
future of the industries it serves: quality of the
products delivered by the customers, energy saving
and environmental safeguard.
Tenova has operating companies in 5 continents and
the Indian Sub-continent, a perfect mix of a global
company with local roots. The network of companies
allows Tenova to be always close to the customers
providing them with technological support, rapid
customer service and short time delivery. The
Tenova Group is part of the Techint Organization,
which also includes Tenaris (worldwide producers
and suppliers of steel pipe), and Ternium (flat and
long steel products producers). The following
companies form part of the Tenova Group:
Tenova HYL
With a heritage of over 40 direct reduction modules
supplied all over the world, including the world’s first
commercial plant built in 1957, Tenova HYL is the
pioneer and technology leader in the field of the
gas based direct reduction of iron ores: one quarter
of the total world production of gas based DRI and
HBI is currently carried out in HYL process plants
throughout the world.
Tenova HYL offers its technology under the
Energiron trademark, in cooperation with Danieli &
C. Direct reduction plants based on the Energiron
process are compact, efficient, reliable and fully
flexible for using not only natural gas but any
alternative reducing gas source such as coke oven
gas, syngas or other gasifier gases depending on
availability.
Tenova HYL provides process technology and
equipment for both hot and cold discharge direct
reduction plants, as well as the HYTEMP® system
for the direct transport and hot charging of high
carbon DRI to Electric Furnace melt shops. Its
support runs from the turn-key construction of direct
reduction plants, to the supply of the core process
design and equipment, up to the delivery of training,
technical assistance and plant operation services
for the direct reduction plant as well as for the
meltshop and mill areas.
The support of the entire Techint organization is
manifest in HYL, with a history of over 50 years of
technology development and implementation in
Techint’s own plants as well as those commercialized
worldwide. This long lasting relationship and
experience has contributed to making Tenova HYL
the unmatched leader for DR technology.
No other direct reduction technology supplier is able
to offer the flexibility and quality that is inherent in
the Energiron ZR technology. The unique ability to
produce high carbon DRI (over 4% carbon) for
quality steelmaking, the more efficient size and
operation of its plants, and the environmental
friendliness of its process technology have become
the benchmark in the industry.
In India, Tenova HYL and the Energiron technology
is extending its roots and fast becoming a major
player in the local direct reduction field. The first
plant using this technology was started up in 1993,
an HBI facility at Vikram Ispat (now part of Wellspun).
SEPTEMBER-2009/24
A second plant at the same site but using the
reformerless or ZR Energiron process configuration
was added in 2007. Additionally, Energiron plants
have been ordered by JSPL using the syngas
process option from coal gasification, and the HYL
HYTEMP System is currently being installed at the
Essar Steel facility in Hazira for transporting hot DRI
to their EAF melt shop.
Additionally, the
HYL Micro-
Module was
developed for
specific markets
such as India,
where small
steelmaking
operations are
numerous. The
Micro-Module is a
scaled-down
plant designed to
produce smaller
quantities
(200,000 tpy) of
DRI while
maintaining an investment cost similar to that of much
larger units (1.0 million tpy or more). The first such
unit will be starting up soon in Abu Dhabi, UAE and it
is expected that this will be the model for many future
installations in India to provide a higher quality DRI
with cleaner environmental aspects over the
traditional coal-based processes. The Micro-Module
is a natural gas-based process and like the larger
plants, can also use syngas from coal gasification.
This is currently not an economically viable option
for small plants, due to the significant investment
cost for the coal gasifier plant. However, where
gasification already exists or is planned for power
generation, the supply of a quantity of that syngas
directed to a Micro-Module DRI plant would provide
substantial profitability.
As natural gas becomes more available and as the
Indian steel industry continues to develop, Tenova
will continue to be a presence here, not only with
direct reduction technology but in other aspects of
steel making as well.
Tenova Melt Shops
Tenova Melt Shops is leader in the design and
supply of Electric Arc Furnaces, Ladle Furnaces,
Vacuum Degassing units, and relevant auxiliary
equipment like the high efficiency chemical package
KT Injection System and the TDR-H Digital
Regulation with Harmonics Control for electrode
movement optimization.
Tenova Melt Shops is the owner of the Consteel®
technology: the continuous feeding and pre-heating
of scrap to the electrical furnace. All over the world
more than 30 Consteel® systems have been
supplied allowing clients to achieve the highest
production efficiencies. It also designs and supplies
dedusting plants, ferro-alloys storage and feeding
systems to the furnace, water treatment plants and
other auxiliary equipment for steelmaking.
Tenova Goodfellow with its EFSOP system, the
unique dynamic EAF process control, completes the
electric arc furnace offering of Tenova Melt Shops.
The EFSOP system is a real time off-gas system
which is continuously measuring and analyzing the
off-gas chemistry to be integrated into the iEAF®
for the dynamic optimization of the efficiency of the
