2. STEEL
Steel is an iron based alloy containing Carbon, Silicon,
Manganese etc.
Terms related to Steel & Steel Products
Sponge Iron/DRI (Direct Reduced Iron)
• Produced by direct reduction of iron ore
Scrap
• Materials left over from product consumption such as
vehicles, building supplies etc.
• It is recyclable
Pig Iron
• Produced by melting iron ore under high pressure
with Charcoal and limestone
• High Carbon content makes it brittle & unstable
3. Commercial forms of IRON derived
from Pig iron by melting & blending
Cast iron
(2.5% carbon)
Pig Iron
Wrought
Steel Iron
(0.5%-1.5% (purest
Carbon) form,0.25%
carbon)
Grades Of Pig Iron:-a) Foundry Grade Pig Iron
b) Basic/Steel Making Grade Pig Iron

Ingot
• Metal that is cast into a shape suitable for further processing
• Manufactured by the freezing of molten liquid in a mold e.g.-
Gold ingot,Aluminium Ingot etc.
Billet
• Small semi-finished casting products that is
rectangular,square,circular in shape area< 36 sq. in
• Further processed via profile rolling & drawing
Re Bar
• Commonly known as Steel Bar
• Used as Tensioning device, anchoring purpose
5. Grades Of Iron Ore
High grade
Medium (+ 65% Fe)
Grade
(+62-65% Fe)
Low Grade
(-62% Fe)
6. Trade of Iron Ore
Lumpy/Fine Ore : Iron Ore is traded in
lumps (i.e. sized ore) or in fines.
Production/availability of lumps is limited
by virtue of the natural occurrence and
also because of generation of lot of fines
during crushing of large lumps present in
the run-of -mines.
7. COAL/COKE
Coal is a naturally occurring combustible rock
containing 70% (by Vol) carbonaceous material
including moisture.
• Coke: Coke is the residual solid product obtained upon
carbonisation of coking coal
8. Ferro Alloys
It refers to various alloys of iron with a high
production of one or more other element
e.g.managanese, silicon etc.
Used in production of steel s and alloys as a
raw material
Ferro Alloys are used to add characteristics
of anti-Corrosion & de-oxidation
Widely used to produce chemicals, Welding
Electrodes, Electrical equipments etc.
