Silicon manganese for high qulity steel
Silicon manganese 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 Silicon-manganese has strong affinity with manganese and oxygen. Deoxidation products MnSiO3 & 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 silicon-manganese alloy, the burning loss rate is 29%. Therefore, it is widely used in steelmaking industry and has become the essential deoxidizing agent and additive in steelmaking industry. Silicon manganese which content has a low carbon content by 1.9% is the semi-finished product used in low carbon ferromanganese and electro silicothermic metal.
