Application
Ferrosilicon is made from coke, steel chips, quartz (or silica) by electric furnace smelting. Silicon and oxygen can be easily converted into silicon dioxide. Therefore, ferrosilicon is often used as deoxidizer in steelmaking. At the same time, due to the large amount of heat released during the formation of SiO2, it is also beneficial to improve the temperature of molten steel while deoxidizing. Ferrosilicon is used as alloying element additive. It is widely used in low alloy structural steel, bonded steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is commonly used as reductant in ferroalloy production and chemical industry. The silicon content is 95% - 99%. Pure silicon is often used to manufacture monocrystalline silicon or prepare nonferrous metal alloys.In the steel-making industry, about 3 ~ 5kg 75% ferrosilicon is consumed for each ton of steel produced.
