Related introduction
Ferrosilicon is widely used in the steel industry, foundry industry, and other industrial production.
Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In Torch Steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to the steel can significantly increase the strength, hardness, and elasticity of the steel, increase the magnetic permeability of the steel and reduce the hysteresis loss of the transformer steel. Normal steel contains 0.15%-0.35% silicon, structural steel contains 0.40%~1.75% silicon, tool steel contains 0.30%~1.80% silicon, spring steel contains 0.40%~2.80% silicon, and stainless acid-resistant steel contains Silicon is 3.40% to 4.00%, heat-resistant steel contains silicon from 1.00% to 3.00%, and silicon steel contains silicon from 2% to 3% or higher.
High-silicon ferrosilicon or siliceous alloys are used as reducing agents in the production of low-carbon ferroalloys in the ferroalloy industry. Ferrosilicon added to cast iron can be used as an inoculant for nodular cast iron and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.
In addition, ferrosilicon powder can be used as a suspension phase in the beneficiation industry, and as a coating for welding rods in the welding rod manufacturing industry; high-silicon ferrosilicon can be used to prepare pure semiconductor silicon in the electrical industry and can be used to make the silicone in the chemical industry.
