Nitrogen-bearing Ferrosilicon FeSiN Nitrided Ferro Silicon Lumps Used In Refractory And Steel Industry


Ferrosilicon nitride description:


Ferro silicon 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 off-white granular.


Differences between ferro silicon nitride and silicon nitride

The uses of ferrosilicon nitride and silicon nitride are very similar, but their main components are different. Ferro silicon nitride is accompanied by free iron, but silicon nitride contains very little iron.

The price of ferrosilicon nitride is about half of that of silicon nitride, and the performance of the two is nearly the same.

Properties Of Ferrosilicon Nitride

Ferrosilicon nitride is an emerging high-quality refractory raw material, which can replace the higher price of silicon nitride and is used in the tap hole mud of large blast furnaces. It has good opening properties, sintering aid, corrosion resistance, and low-cost characteristics.

In all cases, the introduction of ferrosilicon nitride improves the high-temperature strength and wear resistance of refractory materials, improves their thermal stability and oxidation resistance, and reduces the thermal expansion coefficient while increasing the thermal conductivity. It is also important that refractories are more resistant to wear from hot metals and slag. In addition, the refractory material does not shrink when heated repeatedly. The tap hole mud containing ferrosilicon nitride is most effective for the tap hole of the closed furnace with a large working space.


Advantages Of Ferrosilicon Nitride


Improve the high-temperature strength and wear resistance of refractory materials, improve the thermal stability and oxidation resistance, and reduce the thermal expansion coefficient, while increasing the thermal conductivity.
Compared with the traditional manganese and chromium alloys used for alloying, the consumption of ferrosilicon nitride is much less.


The Preparation Of Ferrosilicon Nitride


Ferrosilicon nitride is usually synthesized with ferrosilicon alloy or monatomic silicon at high temperatures using nitriding technology. In the synthesis process, the following two factors greatly affect the synthesis effect.

Ferrosilicon granularity: the relationship between the nitrogen content of products with different particle sizes and the reaction temperature.
The finer the ferrosilicon, the smaller the porosity of the sample, the larger the specific surface area, and the faster and more intense the reaction. However, the more severe the sintering between ferrosilicon particles, the worse the nitrogen diffusion and the worse the nitriding effect. The specific surface area of the coarse-grained sample is small, the nitriding reaction is more stable, and the nitriding becomes more sufficient as the temperature rises.

Nitriding temperature: High-temperature nitriding is more complete than low-temperature nitriding


OTHER NITRIDES ALLOYS:

Usually applied as an additive in the production of stainless steel, Special steels, Technical ceramics, Refractories and Tap Hole, Refractory paints, Industrial paints, Provide thermal and corrosion resistance. Other nitrided alloys available at Zhenxin are: Nitrided Ferro Chromium, Nitrided Silicon Manganese, Nitrided Silicon, Nitrided Ferro Manganese.
