An iron alloy composed of iron, iron, and silicon (using silica, steel, and coke as raw materials, and silicon reduced at a high temperature of 1500 to 1800 degrees Celsius is melted into molten iron to form a ferrosilicon alloy). It is an important alloy variety in the smelting industry.

 

 

 

Ferrosilicon is widely used in the steel industry, casting industry, and other industrial production.

 

Ferrosilicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxygenation and diffusion deoxygenation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve its strength, hardness, and elasticity, increase its magnetic permeability, and reduce the hysteresis loss of transformer steel. Generally, 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, stainless acid resistant steel contains 3.40% -4.00% silicon, heat-resistant steel contains 1.00% -3.00% silicon, and silicon steel contains 2% -3% silicon or more.

 

 

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

In addition, 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; High silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon, and in the chemical industry to manufacture silicone and other materials.

In the steelmaking industry, approximately 3-5 kg of 75% ferrosilicon is consumed for each ton of steel produced.

Melting point: 1300 ℃ for 75FeSi
