Description:

1. AN OVERVIEW OF BOKARO STEEL PLANT

2. Introduction
BOKARO SAIL is the fourth largest integrated Steel plant (PUBLIC SECTOR) in India.
At present it houses five blast furnaces with total capacity to produce 4.5 MT of liquid steel.
It manufactures Steel which is an alloy of iron and carbon where the carbon content is 0.2 to 2.5% which depends upon the grade of steel.
Melting temperature of iron = 1536 degrees Celsius.

3. OBJECTIVE
To interact and learn from the experience of trained engineers,supervisors and other organization employees.
To differentiate between real working scenario and uncertainties and the text book knowledge and to analyses the gap between the two.
To get an insight into the various processes and the sequence of steps in the manufacture of steel and other products.
To understand and appreciate the extent of coordination required between various departments for the success of the organization.

4. Raw Materials & Material Handling Plant (RMHP)
Functions
4 Raw Materials
Suppliers
Process
18 Beds
Wagon Tiplers
Stackers
Reclaimers

5. Coke Oven & BPP
Battery of ovens.
Coal is converted into coke in anaerobic conditions at temperature-1250 degrees Celsius.
Cars involved for production :-
Pusher car.
Guiding car.
Quenching car.
Charging car.

6. Sinter Plant
Agglomerated mass of iron ore, flux
Increases efficiency, reducibility,
reduces coke rate
Fed into sinter furnace on moving pallets
Crushed cooled
+5mm crushed sinter sent to BF & rest reused

7. Steel melting shops-sms1 & sms2
Steel melting- process of removal of impurities like carbon and silicon.
Oxygen blowing process.
It receives hot metals from blast furnace.
Output of sms1 is in ingot form.
Output of sms2 is in slab form.
From sms2 it goes to continuous casting shop.
Molten metal to CCS

8. Continuous Casting Shop
SRU : refining, composition, temperature
Argon purging
The main function of Continuous Casting Shop is to produce steel slabs directly from the molten steel coming from SMS-II and sending them to Hot Strip Mill (HSM) for hot rolling.

9. Slabbing Mill
SMS 1 – Ingot route
Ingot rolling
Same function as CCS
Rolling
Shearing
Piling

10. HOT STRIP MILL
Hot rolling- plastic deformation of metal above crystallization temperature by squeezing it between pair of roller.
The capacity of HSM=4 MT.
HSM has 2000 mm wide strip
Mill.

11. Electrical repair shop 1 & 2
Ac Arc Welding : Only used in the transformers.
Carbon Brushes : Repaired in the
broker arm.

Autotransformers: Used as
the current regulators.
Motors:
Squirrel cage motors.
Synchronous motors.
Slip ring motors.
