What is the meaning of ferrosilicon nitride?
Ferrosilicon nitride is a common steelmaking additive. In the steel smelting process, ferrosilicon nitride can not only provide a nitrogen source for the molten steel, but also effectively remove excess oxygen in the molten steel, and has a good deoxidation effect. In addition to being used as a deoxidizer in steel smelting, ferrosilicon nitride is also a raw material for silicon nitride ceramics. It has good high-temperature resistance and hardness. To deepen everyone's understanding, let's analyze the emergence of ferrosilicon nitride. What meanings does it bring?
| Product | N | Si | Fe | O | Water | granularity |
| FeSi3N4 | 28-32% | 48-52% | 12-17% | 2.5% max | 0.3% max | 0-50mm Special granularity can be customized |
Ferrosilicon nitride is widely used in many developed countries. It can effectively improve the opening and blocking performance of blast furnace mud and meet the needs of blast furnace tapping. It is an indispensable component of modern large blast furnace gun mud and is added to the iron trench material. A small amount of ferrosilicon nitride can greatly increase the iron flow rate of high-speed iron trenches.
In steelmaking, granular ferrosilicon nitride is used in the production of oriented silicon steel. It can replenish a certain amount of nitrogen to molten steel in a relatively stable manner. The amount of ferrosilicon nitride used in China reaches hundreds of tons a year. The advancement of smelting technology has enabled the rapid development of high-strength micro-alloyed steel production in my country.
The main strengthening microalloying elements of steel are vanadium, niobium,m, and titanium. After calculation, comparison,n, and actual production application, FeV50+FeSi3N4 micro-alloying solution is used to produce HRB400 steel bars. The alloying cost is 127.61 yuan lower than the cost of FeV50-ton steel alone, and 44.21 yuan lower than the cost of VN12 micro-alloyed steel. If this technology is popularized, it will be of great significance to manufacturers that produce construction steel to reduce costs and increase efficiency. Ferrosilicon nitride, as a cheap alloy that provides a nitrogen source, has good application prospects in other steel types in the future.
In summary, the significance of ferrosilicon nitride is summarized for everyone. It is used in many developed countries and is a good additive product. However, the smelting of ferrosilicon nitride is not that simple, and poor-quality ferrosilicon nitride also has a great impact on smelting.

Ferrosilicon nitride is a ferroalloy material mainly composed of Si3N4, accompanied by free iron, non-silicon nitride, and a small number of other components.
Commercial ferrosilicon nitride for refractory is an off-white or brown powder, while steel-making ferrosilicon nitride is an off-white granular.
Granular ferrosilicon nitride is mainly used in silicon-oriented steel or other steels (Such as HRB400 rebar) that use nitrides to improve strength.
