Bessemer converter is used for
Atomic nos, `Mn = 25, Fe = 26, Co = 27, Ni = 28`

Options

A. steel
B. wrought iron
C. pig iron
D. cast iron

Answer

1

Explanation

Bessemer converter is used for preparation of steel. The iron obtained from blast furnace is impure or pig iron it is then undergo bessemerisation. This process is based on the fact the impurities present in the pig iron are completely oxidised to from almost pure wrought iron. It is then mixed with known amount of spiegeleisen ( an alloy of `Fe, Mn` and `C )` to obtain steel.
