Ferrosilicon is composed of iron and silicon alloys. Ferrosilicon is coke, steel scurf, quartz (or silica) as raw material and using the ***elting furnace made of silicon alloy iron. Because of silicon and oxygen is easy to f new silicon dioxide, so ferrosilicon is often used in steel*** when make deoxidizer, at the same time as SiO2 is created give off a lot of heat, doxycycline in at the same time, to improve the molten steel temperature is also beneficial. At the same time, ferrosilicon can also be used as alloy elements to agent, widely used in low alloy steels, spring steel, bearing steel, heat-resistant steels and electrician silicon-steel in, ferrosilicon in ferroalloy production and chemical industry, are often used as reducing agent.
