Ferrosilicon is often used as deoxidizer in steel making, and it is also beneficial to improve the temperature of molten steel when it is produced with a large amount of heat during the generation of SiO2. Silicon also can be used as an alloy element joining agent, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, silicon in the ferroalloy production and chemical industry, commonly used as a reducing agent.
