Ferroalloy composed of iron and silicon (silicon, steel, coke as raw materials, after 1500-1800 degrees of high temperature reduction of silicon molten in iron liquid, forming ferrosilicon alloy).It is an important alloy variety in smelting industry.

Used as deoxidizer and alloy agent in steelmaking industry.In order to obtain the steel with qualified chemical composition and ensure the quality of steel, deoxidization must be carried out in the last stage of steelmaking. Silicon and oxygen have a great chemical affinity, so ferrosilicon is a strong deoxidizer used for precipitation and diffusion deoxidization in steelmaking.Adding a certain amount of silicon to steel can significantly increase the strength, hardness and elasticity of the steel.
