Production

Siliconmanganese Powder

Silicon in Silicon-manganese has strong affinity with manganese and oxygen. Deoxidation products MnSiO3 & MnSiO4 produced in the steel making procedure has a temperature of 1270°C and 1327°C respectively. 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%.
