# Bessemer converter is used for the preparation of :(A) Steel(B) Wrought iron(C) Pig iron(D) Cast iron

- Bessemer converter has inner lining of silica and dolomite ($MgC{{O}_{3}}.CaC{{O}_{3}}$). Bessemer converter is based on the principle of removal of impurities of pig iron by oxidation. Hot air is blown through the molten iron to remove impurities present in the pig iron. The form of iron obtained after oxidation is pure wrought iron. It is then mixed with an alloy of iron, manganese and carbon which is called spiegeleisen to obtain steel.
