DESCRIPTION
Silicomanganese is composed of manganese, silicon, iron and other elements with a small amount of carbon and other kinds of alloy. It is widely used with a large production.
Silicon in Silicomanganese has strong affinity with manganese and oxygen. Deoxidation products MnSiO 3 & MnSiO4 produced in the steelmaking procedure has a temperature of 1270°C and 1327°Crespectively. They both have the advantages such as a low melting point, large particles, easy floating, and good deoxidization effect etc. Under the same conditions, the burning loss rates of silicon and manganese were 46% and 37% respectively. But with the Silicomanganese alloy, the burning loss rate is 29%. Therefore, Silicomanganese is widely used in steelmaking industry and has become the essential deoxidizing agent and additive in steelmaking industry.
