Silicon iron is in the steel industry essential deoxidizer. Steelmaking, ferro silicon is used to precipitate deoxidization and diffusion deoxidation. Ferro silicon alloy for steelmaking . Adding a certain amount of silicon, can significantly increase the strength of steel, hardness and elasticity, improve steel permeability, reduce transformer steel hysteresis loss of apparent effect.

Ferro silicon industry used in the production of low carbon ferroalloy reducing agent, ferro silicon joined the cast iron can be used for ductile cast iron inoculant; and can prevent the formation of carbides precipitated and promoting graphite spheroidization; improve the properties of cast iron.

key words:silicon iron, fesi, ferro silicon, ferrosilicon, silicon alloy, ferroalloy
