DESCRIPTION
Ferrosilicon is widely used in steel industry, foundry industry and other industrial production. Ferrosilicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used in steelmaking as an alloying agent. High-silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon can be used as an inoculant for ductile iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.
