Ferro silicon is often used as a deoxidizer in steelmaking, and because SiO2 is generated by releasing a lot of heat, it is also beneficial for increasing the temperature of molten steel during deoxidation. At the same time, ferrosilicon can also be used as an alloying element additives and is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry.
