Ferrosilicon is coke, steel scurf, quartz (or silica) as raw material and using made of electric smelting practice. Silicon and oxygen easily dissatisfied silica. So ferrosilicon used to practice as deoxidizer, at the same time as the steel created SiO2 give off a lot of heat, while, can improve the deoxidization of molten steel temperature drop to the original consumption practice steel. Ferrosilicon as gold elements join agent, widely used in low alloy steels, close "steel, spring steel, bearing steel, heat-resistant steels and electrician silicon-steel commonly used to manufacture of monocrystalline or configuration non-ferrous metal alloys.
