How are the carbon impurities removed from cast iron/pig

Dec 23, 20080183;32;Answers. If you mean to make low carbon steel; it is removed from the molten pig iron by blowing pure oxygen onto the surface of a molten pool of the pig contained in an LD converter.The temperature rise from burning all that carbon(and phosphorus and silicon) is quite large, so the melt is cooled with tons of scrap iron before alloy additions are

Steelmaking

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained

Different Types of Iron Ore 911metallurgist

Impurities in Iron Ores. There are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable.
