Question & Answer

User Guide

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.
In the ferroalloy industry, we usually call silicomaganese the silicomaganese article which is used in steelmaking, and as self-employed silicomaganese in low-carbon iron making, and as high-silicon silicomaganese in metal melting. Manganese which can be mixed with silicon, can made in three silicides: MnSiO3, MnSiO and MnSiO3. MnSi is the most stable one of silicide which can be seen from the silicomaganese condition diagram.
Because the free energy negative value formed manganese silicide, it is far greater than the negative value produced from manganese carbide. Higher the silicon is content in the silicon-manganese alloy, lower the carbon will be.
