3.2.1 DRI Kiln:
The production program of the direct reduction plant, as envisaged, is given
below:
Annual Capacity, Tons Description
Existing Expansion
Sponge iron (DRI) lump 193500 TPA 90000 TPA
A refractory lined rotary kiln will be used for reduction of Iron ore in solid state. A
central Burner located at the discharge end will be used for initial heating of the
kiln. Sized Iron ore will be continuously fed into the kiln along with coal, which has
dual role of fuel as well as reductant. Dolomite will be added to scavenge the
sulphur from the coal. A number of air tubes will be provided along the length of
the kiln. The desired temperature profile will be maintained by controlling the
volume of the combustion air through these tubes. The Carbon Monoxide
generated due to the combustion of coal, reduces the iron ore and convert it into
sponge iron. The rotary kiln is primarily divided into two zones viz. the pre
heating zone and the reduction zone. The preheating zone extends over 30 to 50
% of the length of the kiln and in this the moisture in the charge will be driven off
and the volatile matter in the coal will be burnt with the combustion air supplied
through the air tubes. Heat from the combustion rises the temperature of the
lining and the bed surface. As the kiln rotates, the lining transfers the heat to the
charge. Charge material, pre-heated to about 1000oC enters the reduction zone.
Temperature of the order of 1050oC will be maintained in the reduction zone,
which is the appropriate temperature for solid-state reduction of iron oxide to
metallic iron. This hot material will be transferred to rotary cooler. In rotary
cooler the material will cool from 1000oC to 170oC in cooler by spraying water. The

cooler discharge material consists of sponge iron lumps, sponge iron fines and
char. Magnetic and non-magnetic material will be separated through magnetic
separators and stored in separate bins.
3.2.2 INDUCTION FURNACE:
Initially scrap & other metallics such as pig Iron will be charged into the induction
furnace. After scrap & other metallics are fully melted, the temperature of the
melt reaches above 1600oC, and then DRI will be continuously charged into the
furnace. As soon as the charge is melted, bath samples will be taken and
temperature will be measured. There will be 6 nos. (2x12 T & 4x8 T capacity) of
induction furnaces in the SMS plant.
3.2.3 LADLE REFINING FURNACE
Lime, ferro-alloys, aluminium and fluorspar will be added as per the requirement
and the final temperature and analysis will be adjusted.
3.2.4 BILLET CASTER

3.2.6 Sinter Plant
The proposed and sinter plant complex will consist of one sinter Machine of 50 m2
grate area along with associated services facilities. The sinter plant is rated for a
total production of 432000 Tonnes of BF Sinter at a rated productivity of 1.2
t/m2/hr.
3.2.7 Blast Furnace Plant
The blast furnace shop will comprise of one furnace of 125 m3 working volume.
The blast furnace is envisaged to operate with sized lump iron ore, coke, fluxes
and additives. The hot metal produced will be cast at pig casting machines to
produce cold pigs. The liquid slag will be granulated at cast house granulation unit.
The BF top gas will be cleaned in dust catcher and gas cleaning system and
distributed to the stoves, burners for runner drying, boilers for process and
process steam supply. The excess gas will be supplied to power plant.
3.2.8 POWER GENERATION:
The exhaust waste flue gases from the rotary kiln will pass through a waste heat
recovery boiler (WHRB) of 10.5 TPH capacity. The rotary kiln gases will have a
temperature of 1000ºC at the exhaust of WHRB the temperature will be 1700C.
Three nos. of FBC boilers of 1x45 TPH, 2 x 120 TPH capacity will also be provided
to generate steam by using coal, Dolochar, coal Washery rejects as fuel. The
steam generated will pass through respective steam turbines and will be coupled
to respective generators to generate electricity aggregating to 66 MW. This power
generated will be utilized to meet the internal power requirements of the Mini
integrated steel plant. The flue gases will pass over various heat transfer surfaces

3.2.9 PROCESS DESCRIPTION OF COAL WASHERY
The coal washery will be installed inside premise near raw material yard. This
section comprises of coal crushing and screening station and coal washery to
produce clean coal with 25 % ash, appropriately sized and a middling fraction by
treating the raised coals from the mine.
The coal washery has been designed to wash the coal in heavy media circuit to
reduce clean coal with 25% ash and middling. The process consists of crushing of
the ROM coal in a single toothed roll crusher. The crushed coal is then washed in
Zig to produce clean coal and middling with the help of water stream and air
pressure.
3.2.10 MANUFACTURING PROCESS FOR FERRO ALLOYS:
Standard Silico Manganese is smelted at about 1700 – 1800 ºC. This is achieved
by a conventional Submerged Arc Electric Furnace. The three carbon electrodes,
partially submerged in the charge, are supported on hydraulic cylinders for
upward and downward movements to maintain the desired electrical conditions in
the furnace.
The raw materials are thoroughly mixed in the proper proportion before being
charged into the furnace. Manual poking rods or stoker car are used for stoking
the charge on the furnace top. As the charge enters the smelting zone, the alloy
formed by chemical reactions of the oxides and the reductant, being heavy
gradually settles at the bottom. The slag produced by the unreduced metal oxides
and the flux, being relatively lighter, floats on the alloys surface. At regular
intervals the furnace is tapped.

Executive Summary
Mini Integrated Steel Plant
13
Initially the acidic and alkaline effluent streams coming from cation and anion
units of DM plant will be neutralised in a neutralisation tank of size 5m x 3m x
2.5m. Service water will then pass through an Oil Separator to remove the oil
content in the effluent. The pH of Boiler blowdown will be between 9.5 and 10.5.
Hence this effluent stream shall be neutralized in a neutralization tank of size
3m x 4.5m x 1.7m before mixing with other effluent streams. All these effluent
streams will be mixed in a Holding tank along with cooling tower blowdown. Part
of the treated effluent will be recycled into the DRI plant & Rolling mill make-up
water for cooling and the remaining treated effluent will be used for ash
conditioning, dust suppression and for greenbelt development. The sanitary
wastewater will be treated in septic tank followed by soak pit.
Total effluent generation : 1764 m3/day
(Excluding sanitary waste)
Effluent qty. to be used for ash conditioning : 96 m3/day
Effluent to be used for dust suppression : 90 m3/day
Effluent to be recycled in DRI & cont. casting : 275 m3/day
Total effluent qty. to be used for on land for irrigation : 1303 m3/day
Hence a greenbelt of 50 hectares will be developed within the plant premises by
using the treated effluent. A dedicated pipe distribution network will be provided
for using the treated effluent for on land for irrigation.
The characteristics of the treated effluent are well with in the CECB Standards for
on land irrigation. Hence there will not be any impact on ground water / surface
water due to the proposed expansion project.
