The document is a presentation about a steel melting shop located in Bokaro Steel City, India. It provides background on the shop, including that it was established in 1964 and has an annual production capacity of 645,000 tons. It then gives an overview of the global steel industry rankings, with China as the top producer. The presentation goes on to describe the basic steelmaking process, from blast furnaces to convertors to continuous casting, and discusses the role of the steel melting shop within the overall steel production process.

5. STEEL MANUFACTURING

6. WHAT IS STEEL ?
In the beginning, there was iron...
Then came cast iron...
...and finally steel

7. WHAT IS STEEL USED FOR
The structures such as oil
platforms, catalytic converters,
paper clips, mounts for electronic
chips...are all made of steel.
1. In the construction of
bridges or buildings...
2. In the automobile sector for
the manufacture of
automobile parts

8. WHAT IS STEEL USED FOR
3. For everyday uses:
cans,pots,containers,etc...
4. At the heart of food
preservation...
5. In communications... 6. In energy... 7. In health...

9. STEEL PRODUCTS
Semi-finished products(continuous cast steel)
Finished products (rolled steel)

11. HOW IS STEEL MADE-I

12. STEEL MAKING PLANT
Electric Arc Furnace Ladle Furnace Continuous Casting Machine

14. What is a Blast Furnace?
•Blast furnace is used to
reduce and convert iron
oxides(ore) into liquid iron
called "hot metal".
•The blast furnace is a
huge, steel stack lined
with refractory brick.
•Iron ore, coke and
limestone are put into the
top, and preheated air is
blown into the bottom.

16. •Steel is made in steel melting shop in the
refractory lined vessels called LD
Converters by blowing oxygen through the
hot metal bath.
•Steel making is an oxidation process in
which oxygen reacts with the carbon in the
hot metal and releases large quantities of
gas rich in carbon monoxide along with
huge amount of dust.

17. •Hot Metal, Steel Scrap and Fluxes such as calcined lime or Dolomite
are added as charge to the Convertors.
•The gases released from the converter are collected, cooled, cleaned
and recovered for use as fuel in the steel plant.
•The entire molten steel is continuously cast at the radial type
continuous casting machines resulting in significant energy
conservation and better quality steel.
