Introduction:
Silicon manganese is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is a kind of ferroalloy with a wide range of uses and large output, and it ranks second in the amount of ferroalloy products for electric furnace.
Both manganese and silicon in the Mn-Si alloy have a strong affinity with oxygen. When manganese-silicon alloy is used in steelmaking, the melting points of the deoxidized products MnSiO3 and Mn2SiO4 are 1270℃ and 1327℃, respectively, which have low melting point, large particles, and easy to float , good deoxidation effect and other advantages.
Under the same conditions, when manganese or silicon is used alone for deoxidation, the burning loss rates are 46% and 37%, respectively, while for manganese-silicon alloy deoxidation, the burning loss rates of both are 29%.

Application:
Silicon manganese alloy is mainly used as an intermediate material for deoxidizer and alloying agent in iron and steel production, and is also the main raw material for the production of medium and low carbon ferromanganese.
Silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is an iron alloy with a wide range of uses and a large output.
The deoxidation products produced by the silicon manganese alloy have the advantages of low melting point, large particles, easy floating, and good deoxidation effect.
Silicon manganese alloys with a carbon content of less than 1.9% are also semi-finished products for the production of low carbon ferro manganese and electrolytic Manganese metal.
