    Steel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric high frequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an egg shaped vessel, known as a converter, of 15 25 tonnes capacity.
