Introduction
Ferrosilicon is made from coke, steel scraps and quartz (or silica) and is smelted in an electric arc furnace. Ferrosilicon is widely used as a deoxidizer in the steelmaking process. At the same time, because the heat released when SiO2 is formed is relatively large, it is also beneficial to increase the temperature of the molten steel during deoxidation. Ferrosilicon is widely used in low-alloy structural steel, bond steel, spring steel, bearing steel, heat-resistant steel, electrical silicon steel, etc. It is often used as a reducing agent in ferroalloy production and chemical industry.

Application
(1.) Used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steel making. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer used in steel making for precipitation and diffusion deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel.
(2.) In the cast iron industry used as inoculant and spheroidizing agent, adding a certain amount of ferrosilicon in cast iron can prevent the formation of carbide in iron, promote the precipitation and spheroidization of graphite, so in the production of nodular cast iron, ferrosilicon is an important inoculant (help precipitate graphite) and spheroidizing agent.
(3.)Used as reducing agent in ferroalloy production. Not only the chemical affinity between silicon and oxygen is great, but also the high silicon iron silicon has a very low carbon content. Therefore, high silicon ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the production of low carbon ferroalloys in the ferroalloy industry.
