Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.
Ferrosilicon is Fe2Si, Fe5Si3, FeSi, FeSi2 and other silicides formed by silicon and iron. They are the main components of ferrosilicon. Silicon in ferrosilicon mainly exists in the form of FeSi and FeSi2, especially FeSi is relatively stable. Ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and chemical industry.
