Ferrosilicon for steelmaking and casting
First: used as deoxidizer and alloying agent in the 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 steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer used in steelmaking. Precipitation and diffusion deoxidation.
Second: used as inoculant and spheroidizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, has excellent casting properties and is much better than steel in earthquake resistance. Adding a certain amount of ferrosilicon to cast iron can prevent the iron from It forms carbides and promotes the precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant and spheroidizing agent in the production of ductile iron.
