A Review of Steelmaking Technologies

Steelmaking is the method of developing steel from iron ore (usually haematite) and scrap. The impurities such as nitrogen, sulphur, silicon, phosphorus and excess carbon are separated out from the raw iron and alloying elements such as nickel, manganese, vanadium, molybdenum and chromium are added to impart different properties to steel. The technology of steelmaking has made great advancements with time. This paper describes the modern technologies used in a steel plant while reviewing the conventional processes as well.
