Ferro silicon is used in the steelmaking industry as a precipitation deoxidizer and diffusion deoxidizer.

Reducing agent: high-silicon ferro silicon or siliceous alloys can be used as reducing agents for the production of low-carbon iron alloys in the ferroalloy industry.

Alloying agent: Ferro silicon can be used as alloying agent for low-alloy structural steel, composite steel, spring steel, bearing steel, heat-resistant steel and electric silicon steel smelting, to produce single crystal silicon or to prepare non-ferrous metal alloys.

Inoculant: adding ferro silicon to cast iron can be used as an inoculant for nodular cast iron to prevent the formation of

carbides, promote precipitation and spheroidization of graphite, thereby improving the properties of cast iron.

Coating: Ferro silicon powder can be used as a suspension phase in the beneficiation industry, and can be used as a coating for welding rods in the welding rod manufacturing industry.

can be used as alloy elements join agent, widely used in low alloy steel,
