What is the specific role of ferrosilicon nitride in the steelmaking process?

Ferrosilicon nitride has multiple roles in the steelmaking process, which can be summarized as follows:

Deoxidizer: Ferrosilicon nitride can react with oxygen in molten steel to generate nitrogen, effectively removing oxygen from molten steel, thereby improving the quality of steel. Compared with traditional deoxidizers, ferrosilicon nitride has better deoxidation effect and faster degassing speed, which helps to save production time and cost.

Impurity absorbent: During the steelmaking process, ferrosilicon nitride can absorb and bind impurities in molten steel, such as sulfur, oxygen, carbon, etc., which will reduce the purity and strength of steel. Using ferrosilicon nitride as an impurity absorber can effectively improve the quality and purity of steel.

Alloy strengthener: When ferrosilicon nitride is used in steelmaking, the iron atoms in the steel will combine with the nitrogen atoms in ferrosilicon nitride to form a new alloy. This alloy has excellent mechanical properties and can effectively improve the strength, hardness and wear resistance of steel.

Heat resistance: Ferrosilicon nitride has stable chemical properties at high temperatures and will not deteriorate or melt in the high temperature environment of steelmaking, which helps to stabilize chemical reactions and further improve the quality and performance of steel.

In summary, ferrosilicon nitride plays an important role in steelmaking, not only improving the quality of steel, but also helping to improve production efficiency and reduce costs. With the development of technology, the application prospects of ferrosilicon nitride are expected to be more extensive.
