1. Ferrosilicon is an indispensable deoxidizer in steel-making industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.
2. High silicon ferrosilicon or siliceous alloy is used as reducing agent in ferroalloy industry to produce low carbon ferroalloy. When ferrosilicon is added into cast iron, it can be used as inoculant for ductile iron, prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.
3. Ferrosilicon powder can be used as suspended phase in mineral processing industry and as coating for welding rod in welding rod manufacturing industry.
4. Ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pijiang process. It replaces magnesium in Cao. MgO. For each ton of magnesium metal produced, about 1.2 tons of ferrosilicon will be consumed, which plays a great role in the production of magnesium metal.
5. Other uses. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as the coating of welding rod in the welding rod manufacturing industry. High silicon ferrosilicon can be used to manufacture silicone and other products in the chemical industry.
