1. in the steel industry used as deoxidizer and alloying agent: in order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the later stage of steel must be deoxidized, the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for precipitation and diffusion of steel deoxidizer.
2. in the cast iron industry used as inoculant and spheroidizing agent: cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt smelting, has good casting performance and much better than steel earthquake resistance. In particular, the mechanical properties of nodular cast iron reach or approach that of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbide in iron and promote the precipitation and spheroidization of graphite, so in the production of nodular cast iron, ferrosilicon is an important inoculant (help precipitate graphite) and spheroidization agent.
