High-Temperature Ferro Silicon Nitride for Steelmaking

Improving the refractoriness and erosion resistance of ferrosilicon nitride can be achieved through the following methods:

Optimizing the synthesis process: The use of flash combustion synthesis technology can effectively improve the purity and performance of ferrosilicon nitride. This technology helps to form a more uniform and dense structure by quickly synthesizing ferrosilicon nitride in a high-temperature nitrogen flow, thereby improving the refractoriness and erosion resistance.

Adjusting the raw material ratio: By precisely controlling the ratio of ferrosilicon alloy and nitrogen, the nitriding reaction can be optimized to generate more silicon nitride phases, thereby improving the refractoriness and erosion resistance of the material. At the same time, the right amount of iron phase can enhance the sintering performance of the material and further improve its stability at high temperatures.

Introducing additives: During the preparation of ferrosilicon nitride, some additives such as oxides or carbides can be introduced to form a more stable solid solution or composite material. These additives can improve the material's oxidation resistance and slag resistance, thereby enhancing its performance in high temperature and corrosive environments.

Controlling firing conditions: Appropriate firing temperature and holding time are essential to improving the performance of ferrosilicon nitride. By controlling the firing conditions, the formation of β-Si3N4 phase in ferrosilicon nitride can be promoted, which has higher refractoriness and corrosion resistance.

Microstructure regulation: By adjusting the microstructure of ferrosilicon nitride, such as grain size, porosity and phase interface, its high temperature performance can be improved. For example, smaller grains and lower porosity can improve the density of the material, thereby enhancing its corrosion resistance.

Surface treatment: Surface treatment of ferrosilicon nitride, such as coating or impregnation, can form a protective film on its surface, effectively isolating high temperature and corrosive media and improving the service life of the material.

Through the comprehensive application of the above methods, the refractoriness and corrosion resistance of ferrosilicon nitride can be significantly improved, making it show more excellent performance in high temperature and harsh environment.
