Ferrosilicon 75 Metal Description
Ferrosilicon 75 is a ferroalloy composed of iron and silicon. Ferrosilicon is an alloy of iron and silicon made by melting coke, steel filings, and quartz (or silica) in an electric furnace. Because silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking.
At the same time, because SiO2 generates a lot of heat, its use is beneficial in raising the temperature of molten steel during deoxidation. At the same time, ferrosilicon can be used as an additive of alloying elements, and is widely applied 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 the production of ferroalloys and the chemical industry.
