Ferrosilicon

 Detail:

Ferrosilicon is composed of iron and silicon ferroalloy. Ferrosilicon is coke, steel scurf, quartz (or silica) as raw material and using the iron smelting furnace made from silicon alloy. Because of silicon and oxygen easily dissatisfied silica, so when fesi often used in steelmaking, because SiO2 generating oxygen absorber when give off a lot of heat, in the same time, to improve the deoxidization steel temperature is also beneficial. Meanwhile, ferrosilicon can also be used as a alloy elements join agent, widely used in low alloy steels, spring steel, bearing steel, heat-resistant steels and electrician silicon-steel fesi in ferroalloy production of chemical industry, and used as a reductant.
