Ferro silicon alloy is mainly used as charging materials in smelting industries such as ferrous and non-ferrous metals. As a deoxidizer in crude steel smelting in the iron and steel industry, ferro silicon is an essential metallurgical raw material. Item its a lot of heat when SiO2 isgenerated, it is beneficial to increase the temperature of molten steel while deoxidizing. As an alloying element additive, ferro silicon is widely used in low-alloy structural steel, alloy steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.
