Ferrosilicon for steelmaking

1. Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.

2. High silicon ferrosilicon or siliceous alloys are used as reducing agents for the production of low-carbon ferroalloys in the ferroalloy industry. Ferrosilicon can be used as an inoculant for ductile iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.

3. Ferrosilicon powder can be used as a suspended phase in the mineral processing industry, and as a coating for welding rods in the welding rod manufacturing industry.

4. Ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. The magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon are consumed for each ton of metal magnesium produced. Production plays a big role.

5. Use in other aspects. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding rods in the welding rod manufacturing industry. High silicon ferrosilicon is used in the chemical industry to manufacture products such as silicone.
