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.

OBJECTIVE

• To interact and learn from the experience of
  trained engineers,supervisors and other
  organization employees.
• To differentiate between real working scenario
  and uncertainities and the text book knowledge
  and to analyse 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 organisation.

Raw Materials Material Handling Plant (RMHP)

• Functions
• 4 Raw Materials
• Suppliers
• Process

• 18 Beds
• Wagon Tiplers
• Stackers
• Reclaimers

7
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.

8
Sinter Plant

• Fed into sinter furnace on moving pallets
• Crushed cooled
• 5mm crushed sinter sent to BF rest reused

• Agglomerated mass of iron ore, flux
• Increases efficiency, reducibility,
• reduces coke rate

BLAST FURNACE
10
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

SMS II
12
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.
13
Slabbing Mill

• Rolling
• Shearing
• Piling

• SMS 1 Ingot route
• Ingot rolling
• Same function as CCS

14
HOT STRIP MILL

• Hot rolling- plastic deformation of metal above
  crystallization temperature by squeezing it
  between pair of roller.
• The capacity of HSM4 MT.
• HSM has 2000 mm wide strip
• Mill.
