Ferrosilicon nitride wide range of fields
Powdered ferrosilicon nitride is mainly used in the plugging mud of large blast furnaces, and a small amount is used in trench materials or other amorphous refractory materials. With the continuous improvement of refractory quality requirements, more and more refractory materials The product uses ferrosilicon carbide or silicon nitride.
Granular ferrosilicon nitride is mainly used in grain-oriented silicon steel or other steel types that use nitrides to improve strength.
The main functions of nitrogen in steel are solid solution strengthening and age precipitation strengthening, improving the macrostructure of steel, making it dense and solid, improving strength, hardness, creep, wear resistance, corrosion resistance, impact resistance, and improving its bonding properties. .
Silicon nitride is also a desalination ceramic with the characteristics of small thermal expansion coefficient, high hardness, high elastic modulus and good thermal stability. Adding silicon nitride to magnesia castables can significantly improve the resistance to slag penetration during casting.
Silicon nitride is used in the production range of high-nitrogen steel, high-nitrogen alloy steel, high-strength steel, stainless steel, and tool steel, as well as in the national defense industry, aerospace industry, and thermal insulation materials industry.
Ferrosilicon nitride is also suitable for the smelting of special steel and stainless steel. Because of the large expansion coefficient and hardness of nitride, its stability is very good. Ferrosilicon nitride products are also widely used in ceramic processes, glass production processes and high-temperature material processes.
