The flow diagram of Manufacturing Process is shown in Figure. 4 below & Block diagram in
figure 5.
Receipt, Storage & Handling of Raw Materials (Sinter Plant & BF Area)
Page 11
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
11
The raw materials comprising iron ore fines, iron ore lumps, limestone & dolomite, quartz,
manganese ore, coke, coke fines required in Sinter Plant & Blast Furnace for iron making; are
received by road and stored in the respective stockpile area earmarked in the yard in open
manner. However, coal and lime is stored in a covered shed. Storage of about 7 days is
maintained.
Reclaiming and Transport of Raw Materials to consuming areas in Sinter Plants & Blast
Furnace
SINTER PLANT
Iron ore fines, mill scale, quartz reclaimed by a payloader from stockyard is fed to a hopper
located over the yard conveyor and transported to the proportioning bins at sinter plant through a
series of conveyors. Flux materials viz. limestone and dolomite will be fed to another hopper one
at a time by a payloader. The flux materials will be crushed and screened to -3mm size and
stored in the respective proportioning bins in the sinter plant building. Coke breeze after crushing
to -3mm size will be stored in the proportioning bins earmarked for the purpose. Electromagnetic
tramp iron separators, dust extraction system and belt scales are provided in the system as per
requirement. Schematic flow diagram for Raw Material is shown in Figure below
Sintering Process
In the sinter plant, the various raw materials are discharged in the desired proportion from the
proportioning bins and mixed with right quantity of water in a primary mixer followed by further
mixing in a secondary mixer. The green mix is then fed to the circular sinter machine over a
hearth layer of return sinter. The material then passes through an ignition furnace fired by BF gas
to ignite the coke in the mix. The material gets sintered by sucking of air from top through the
material layer to burn the coke and raise the temperature for agglomeration of the material.
The hot sintered material is broken to small pieces by a single roll crusher & screened in a
vibrating hot screen which discharges into an annular cooler for cooling to <100°C by blowing
air through the material. 0-5mm fraction from hot screen will be re-circulated to the sinter plant
through proportioning bins.
Page 12
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
12
The cooled material is then conveyed to the BF section. Return fines 0-5mm from BF will also
be reversed to proportioning bins. ESPs are installed both at head & tail ends to clean the air
before discharging to atmosphere.
BLAST FURNACE
The sinter from the sinter plant shall be conveyed to the sinter bins in BF stock house by a belt
conveyor. Sinter shall form 80-85% of the metallic charge.
Sized iron ore/Pellets, coke and fluxes will be delivered to the BF stock house by a conveyor
from storage yard.
Coke, sinter and ore will be screened to remove fines before charging to the blast furnace. These
fines are re-used in the process.
Smelting Process in BF
The sinter & iron ore lumps/Pellets are smelted in BF using coke and injection coal as reductant
and source of supply of heat. Hot air at 1100-1150°C enriched by 2-3%. Oxygen is supplied to
provide oxygen for combustion of coke. The air is heated in stoves working on regenerative
principle using a part of BF gas as a fuel. The hot metal and slag is tapped periodically at about 2
hours intervals. Slag is granulated by high pressure water jet and collected in a pond. The hot
metal is collected in refractory lined ladles for use in steel melt shop/ pig casting in the pig
casting shop.
BF gas is used as a fuel in preheating of blast air in stoves, ladle heating and ignition furnace of
sinter plant. The balance BF gas is used in captive power plant, reheating furnaces of rolling mill
etc.
STEEL MELTING SHOP
a) Raw Material Handling
The metallic charge in the steel melting shop shall be;
Hot Metal : ~65%
DRI : ~31%
Revert Scrap : ~4%
It will be processed in the shop through Electric Arc Furnace (EAF), Ladle
Page 13
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
13
Refining Furnace, Vacuum Degassing (only for alloy steels) and continuous
casting route to produce billets.
Hot metal shall be transported to the SMS in refractory lined ladles by special
trucks. The metal shall be charged into the EAF by EOT crane through a launder.
The DRI will be purchased and received in trucks which will discharge in ground
hopper and conveyed to day bins by a high rise conveyor. Burnt lime & dolomite
shall be received in waterproof bags and stored indoor. The bags shall be opened
& material supplied to EAF day bins by a payloader discharging to the ground
hopper feeding the high rise conveyor feeding the day bins.
b) Melting & Refining Process in EAF
After charging of scrap and hot metal, melting process starts by blowing oxygen
and supplying electrical energy by direct arcing. The continuous DRI feeding is
started after 4-5 minutes along with lime & dolomite. The melting and refining
for de-phosphorization & partial desulphurizing take place simultaneously. The
slag formed is removed continuously. On complete meltdown sampling is done.
Further oxygen blowing & power input are carried out as per sample result. The
temperature is raised to about 1620°C. The arcing & oxygen blowing is stopped
and the steel tapped in a heated refractory lined ladle. About 15-20% metal is kept
in the furnace as hot heel by quick tilt back to ensure slag free tapping through
eccentric bottom tap hole. During tapping fluxes and ferro alloys are added to suit
further treatment.
The furnace slag line refractory is inspected and repaired by gunning, if required.
The furnace is then ready for next heat.
c) Secondary Refining in Ladle Furnace
The secondary refining of steel is carried out in the ladle furnace under a reducing
basic slag for de-sulphurization. The steel is continuously kept in homogenized
conditions by stirring achieved through purging of argon gas through a porous
plug installed in ladle bottom. Heat is supplied by direct arcing under the slag
Page 14
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
14
layer. Fluxes and ferro-alloys are added as required to achieve the desired
composition. Sampling & temperature measurement is done 2-3 times to control
the process and achieve right composition and temperature for continuous casting.
Feeding of aluminium and calcium silicide is carried out by wire feed machine for
some of the grades for de-oxidation, desulphurization and inclusion control.
The Ladle Furnace also serves an important function of acting as a buffer between
EAF and Continuous Casting Machine to achieve sequence casting of several
heats together and thus helps in achieving higher yield of billets.
d) Vacuum Degassing
Most of the alloy steel grades for critical application like automobile, railways
and general engineering application require the liquid steel to be degassed under
vacuum to lower the content of harmful gases viz. hydrogen, nitrogen and
oxygen. The ladle after the ladle refining furnace processing is placed in a tank
and sealed by a cover. Argon is purged through the porous plug to stir the liquid
steel and vacuum upto 0.5 Torr applied for 15 to 20 minutes to lower the
hydrogen content to a level of less than 2 ppm and that of nitrogen to about 25-30
ppm. The alloying and addition of deoxidizers is carried out under vacuum.
After the completion of treatment, vacuum is broken and wire feeding of calcium
silicide wire is carried out for achieving further de-oxidation, reduction in
inclusion level and achieve modification in their morphology. The steel is now
ready for casting in continuous casting machine.
e) Continuous Casting of Steel
The Ladle after LF treatment or LF-VD treatment is carried by EOT Crane to the
Turret of Continuous Casting Machine. The turret is then rotated through 1800 to
bring the new ladle to casting position and take the previous empty ladle to
removing position. Molten steel is fed from the ladle into a tundish with stopper
controlled nozzles / metering nozzles to permit accurate apportioning of the steel
into the mould.
Page 15
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
15
When commencing the casting operation, the head of the Starter Bar is tightly
sealed in the mould and retained by the driven rollers of the withdrawal and
straightening machine.
From the tundish, the steel is fed into the water cooled mould. A lubricant
(casting powder) is fed to the mould during casting to obviate wetting of the
mould wall by liquid steel and reduce friction between strand & mould. A mould
oscillator imparts an oscillating motion to the mould @ 120-200 c/s.
The strand leaving the mould with only a thin shell is guided by guide rollers
installed below the mould, is further solidified by direct spraying with water.
The casting speed is such as to ensure complete solidification of strand before it
enters the withdrawal-cum-straightening rolls.
The strand i.e. billet now approach the Torch Cutting Machine, the strand is sub-
divided to desired billet length of 6-12 m.
After the starter bar has left the withdrawal machine, it is disconnected from the
billet and moved to its storage station.
The billets then run forward on a roller table to the billet handling bay and are
transferred to the Cooling Bed. These are either cooled to 4000C and lifted by
magnet cranes to storage area. There is provision for hot charging of billets
directly to Billet Reheating Furnace of the Rolling Mill.
ROLLING OF BILLETS INTO ROLLED PRODUCTS
The billets are heated to rolling temperature of 1150 to 12000C in the Walking Beam Type Billet
Reheating Furnace. The billets shall then undergo high pressure water descaling before being
rolled for five (5) passes in a mechanized 3-High Single Stand Roughing Mill.
Further rolling shall take place in a 14-Stand Continuous Mill. Defective ends of the bar shall be
cropped after 7th
and 13th
pass by Crop-Cum-Cobble Shear.
Page 16
PFR of Expansion of Integrated Steel Plant from 0.3 MTPA To 0.5 MTPA, 4.7 To 30 MW Waste Heat Recovery Power Plant & Proposed 0.3 MTPA Coke Oven Plant
16
The rolled bars 8 to 40 mm size for reinforcement application shall be quenched by high pressure
water online after final rolling to produce high strength TMT Bars. The carbon and alloy steel
bars are not subjected to this treatment.
The bars are then divided to cooling bed length, cooled onto an automatic rake type cooling bed.
The cooled bars are delivered onto the cooling bed run-out table for sub-dividing to customer
required length in cold shear provided with Measuring Gauge.
The bars are then bundled, tied, weighed and deposited on to the Bundle Bed of Bar Handling
System. These are lifted by EOT Magnet Crane for storage and despatch.
Alloy Steel bars undergo inspection by reopening the bundle for surface and internal defects,
conditioned and re-bundled for despatch.

3.0 Environmental Pollution Mitigation & Control Measures
Right from the extraction of ores to steel making through various processes involving ore
preparation, smelting, refining, casting and rolling to finished products, there is generation of
large but manageable quantities of waste products and pollutants at every stage. However, with
focused approach, the technologies, processes and equipments have been devised to profitably
utilize the waste products and bring down the pollutants to levels that are safe enough for the
personnel working in the steel plant as well as the general public and society at large.
Thus, modern steel plants are designed to provide safe and healthy environment to both the
operating personnel and the populace in the vicinity. The types of possible pollutants which need
to be tackled are
Air Pollution through discharge of waste gases containing Carbon Mono-oxide, Sulphur
Dioxide, Nitrogen oxides and Particulate Matter of flue dust, ash, iron oxide etc N
Water Pollution through discharge of water containing various chemicals, oils, grease etc.
Thermal Pollution through discharge of hot gases, steam and radiated heat to the
atmosphere.
Noise Pollution.
Land Pollution through discharge of solid wastes.
The pollution mitigation measures which would be considered as an integral part of the design of
the proposed plant facilities are outlined in the following sub-sections
3.1 Air Pollution Mitigation Measures
3.1.1 Raw Material Handling Area
Fugitive dust emissions generated from handling and transfer of the material would be

treated water would be utilized in dust suppression.
The plant sanitary waste water including canteen effluent would be treated in a modular
type sewage treatment plant for separation of floating oil and reduction of BOD and the
treated effluent would be used for dust suppression and maintenance of plant green belt.
3.3 Work Zone Pollution Mitigation Measures
o The work zone pollution would be mostly fugitive dust, heat and noise. The fugitive dust
emission in open area would be controlled by Dust Supression and Dust Extraction
Systems described earlier.

o Work zone thermal pollution would be abated by providing adequate thick refractory
lining in all process vessels generating heat. In addition to this, there would be provision
for forced draft cooling and ventilation of closed environment in the work zone.
o Noise arising from the machineries like crushers, vibrating screens, compressors,
blowers, fans, pumps etc. cannot be eliminated. The mitigation measures adopted for
such noise prone equipments would be done by installing these noisy equipment in a
separate building / housing so as to enhance the noise attenuation.
