The main components of silicon manganese nitride are ferrosilicon nitride, ferromanganese nitride, and other small amounts of mixed elements. The reason why many steel plants purchase silicon manganese nitride in large quantities and add silicon manganese nitride during steelmaking is mainly because silicon manganese nitride can improve the overall performance of steel.
Silicon manganese nitride can react with oxygen in steel to generate nitrogen and manganese silicate, thereby deoxidizing. The function of the deoxidizer is to remove oxygen from the steel, prevent pores and inclusions in the steel, and improve the quality and performance of the steel.
Manganese in silicon manganese nitride is an important alloying element that can improve the hardness, strength and wear resistance of steel. Manganese can also improve the weldability and cold working properties of steel, and improve the plasticity and toughness of steel.
The nitrogen in silicon manganese nitride can react with the carbon in the steel during the steelmaking process to form nitrides, such as iron nitride, vanadium nitride, etc. These nitrides can increase the hardness and wear resistance of steel, and improve the cutting performance and wear resistance of steel.
Silicon manganese nitride plays the role of deoxidation, alloying and nitriding in steelmaking, which can improve the quality and performance of steel, making the steel have better hardness, strength, wear resistance and processing performance. In addition, silicon manganese nitride is mainly used as a nitrogen increasing agent for oriented silicon steel, a nitrogen increasing agent for high strength steel, and can also be used as a nitrogen increasing agent for casting.
