Sponge Iron Plant
The production process of sponge iron involves four steps
namely:
i. Raw material preparation plant: The raw material preparation
plant consists of
crushers and screens through which the seized material required
for process is
prepared. Normally, jaw crushers are used for iron ore crushing
and roll or impact
-
PREFEASIBILITY REPORT ASR STEELS & POWER PRIVATE LIMITED
DETOX CORPORATION PRIVATE LIMITED 16 2015
crushers for coal. The feeding for the crushers are done through
the conveyors and
vibrating feeders.
ii. Stock house: The stock house consists of the raw material
storage bins; which store
material up to 24 hours plant requirement. There are four bins
one each for iron ore,
feed coal, dolomite and injection coal. The raw materials are
fed into a rotary kiln
through the volumetric/weigh feeders at a predetermined
rate.
iii. Reduction kiln: The processing of the materials consists
mainly of kiln and cooler
system. The iron ore is pre-heated and reduced in a rotary kiln
and passes to the
rotary cooler; where it gets cooled. The cooled material is then
passes to the belt
conveyor; where the cooler discharge is fed to the product house
conveyor. The
material is then led to the product separation circuit. An
intermediate bin is provided
to take care of any eventualities occurring due to breakdown of
the product
separation circuit.
iv. Product separation plant: In the product separation section,
the sponge iron and the
coal-char (un-burnt coal) are separated. The cooler discharge
material is screened to
different sizes, and fed into magnetic separator. The sponge
iron is magnetic and
hence, it gets attracted to the magnet present in the magnetic
separator and is
discharged to separate bins the dust in the hot gases settles
and gets cleaned.
Operation of Rotary Kiln and Cooler:
Rotary Kiln: Rotary kiln is 3.0 m in diameter and 42 m long; and
it is positioned inclined at
an angle of 1.432o approximately. It is rotated by AC variable
speed motor at a stem less
variable speed ranging from 0.2 to 1.0 RPM. Due to the
inclination and the rotary motion in
kiln; the material moves from the feed end of the kiln to the
discharge end in approximately
4.5 hours. The fine coal is blown from the discharge end to
maintain the required
temperature profile. The material and the hot gases move in the
counter current direction.
As a result, the iron ore gets preheated and gradually reduces
by the time it reaches
discharge end. The reduced material is then transferred to the
rotary cooler via transfer
chute.
Rotary Cooler: The rotary cooler is 2.3 in diameter and 22 m in
length. It is also inclined at
1.432o approximately. It rotates at 1.2 RPM. It is driven by AC
motor. The water is sprayed
on top of shell; which cools the material inside the cooler
indirectly. The material reaches 80 oC temperatures approximately;
and discharged by the double pendulum valve to the
conveyor. The double pendulum valve actually acts as a seal for
prevention of atmospheric
-
PREFEASIBILITY REPORT ASR STEELS & POWER PRIVATE LIMITED
DETOX CORPORATION PRIVATE LIMITED 17 2015
air entering the rotary cooler. The material discharged on
conveyor is then sent for product
separation system. Here, the material is segregated in different
sizes and also magnetic
sponge iron is separated from non-magnetic char.
The gases flowing into counter current direction gets to the
dust-settling chamber and
heavier particles settles down. These particles are continuously
removed by the wet
scrubbing system. The gases then pass to the Forced Draft (FD)
Cooler; where the gases
are cooled. The gases leaving the kiln are very hot and have a
lot of heat energy. The gases
are then passed through Electrostatic Precipitator (ESP) for
dust concentration to reduce
below the acceptable norms and discharged to the atmosphere
through stack of adequate
height.
Figure 4: Sponge Iron Manufacturing Flow Diagram
Waste Heat Recovery Boiler System
The waste heat recovery boilers are designed to operate only
with the thermal energy in the
waste gases from the rotary kilns and these boilers do not need
any supplementary or
auxiliary firing. There is no fuel usage in the waste heat
recovery boilers. The waste gases
from After Burning Chamber (ABC) of Sponge Iron Kilns will be
conveyed to the waste heat

boilers through gas ducts. Proper refractory lining shall be
given for the ducting as the
gases will be coming at high temperature in the range of
950–975oC
Alloy Steel Product
Induction arc Furnace
The induction arc furnace is the principle furnace type for the
production of the Alloy Steels.
The primary application of the furnace is for the re-melting of
the steel scrap or sponge iron.
Furnace Operations:
The induction arc furnace operates as a batch melting process
producing batches of molten
steel known “heats”. The furnace operating cycle is called the
tap-to-tap cycle and is made
up of the following operations:
• Furnace charging
• Melting
• Refining
• De-slagging
• Tapping
• Furnace turn-around
Charging:
The charging material consisting of steel scrap & additives
is loaded into the furnace in such
a way that large and high melting pieces stand parallel close to
crucible while low melting
Components in the middle of the crucible.
Melting:
At the beginning of melting the furnace works for 5 to 10
minutes on low power until the
surge of current fed from the generator disappear. The furnace
power is then brought up to
a maximum. The charge melts with the crucible held closed. When
the charge approaches
the fluid stages than the solid pieces are pressed back with a
crow bar. The furnace is then
loaded to its capacity by adding small size of scrap as soon as
the charge melted. The slag
is formed to protect the metal from oxidation and to avoid
reduce the melting loss. Excess
slag is skimmed off periodically. At the last, Ferro Manganese,
Silicon Manganese & Ferro
Silicon is added to deoxidize the metal.
Ladle Refining Furnace:
Ladle refining furnace (LRFs) are used to desulfurize steels,
remove other impurities and
hold the molten steel for casting operations. Without LRFs,
higher tap temperatures are
normally required from steel making furnaces due to heat losses
during refining during
-
PREFEASIBILITY REPORT ASR STEELS & POWER PRIVATE LIMITED
DETOX CORPORATION PRIVATE LIMITED 19 2015
conventional ladles. Costs of extended furnace time, refractory
wear and power or fuel
consumption can all be reduced using LRFs to perform holding and
refining. The ladle
refining furnace also acts as a buffer between the steel making
furnace and continuous
caster, reducing casting costs and allowing greater flexibility
in steel making operations.
Ladle Refining Process:
Large ladles are used in most metal melting operations to
transfer molten metal from
melting furnaces to refining or pouring stations. Ladle refining
furnaces are basically ladles
with a heating source and lid. LRFs are used to reheat or
maintain steel tapped from a steel
making furnace to a precise temperature and or refine it to
exact chemical specifications.
Refining is performed by adding chemicals to remove impurities,
adding ingredients which
enhance strength, and homogenizing the molten steel to achieve
uniform characteristics.
LRFs provide an ideal reining station with precise temperature
control, stirring action for
homogeneity, and ports for alloy addition and slag removal.
Reheating steel in a ladle
refining furnace is typically accomplished by electric arc
heating.
AFBC Power Plant
The design, manufacture, inspection, testing and installation of
all equipment and system of
the proposed captive power plant shall confirm to the latest
editions of Indian and
International codes and standards. Best Engineering Practices
shall be followed wherever
the relevant standards are not available.

Environmental Impact Assessment (EIA) is a formal process used
to predict how industrial
development or construction project will affect natural
resources such as water, air, land,
socioeconomic and bio ecological environment.
An EIA usually involves a sequence of steps:
(1) Screening to decide if a project requires assessment and to
what level of detail.
(2) Preliminary assessment to identify key impacts, their
magnitude, significance, and
importance.
(3) Scoping to ensure the EIA focuses on key issues and to
determine, where more detailed
information is needed.
(4) Implementing the main EIA study, which involves detailed
investigations to predict
impacts, assess their consequences, or both.
Methodology
Environmental Impact Assessment (EIA) studies include
identification, assessment,
quantitative evaluation and prediction of possible impacts. To
minimize the impact of the
project on various environmental attributes, mitigation measures
are suggested for
implementation along with the project.
The methodology of this study can be schematized as detailed
below:
To gather information on present environmental conditions and
relevant national
environmental guidelines and EIA procedures.
Scoping of impacts.
Assessment of significant impacts.
Description of residual impacts.
