In the heart of industrial production, LSFerroalloy stands out as a leading manufacturer specializing in nitride products that are revolutionizing the steel and refractory materials sectors. The company is dedicated to producing a wide range of high-quality nitride products, including ferrosilicon nitride (Fe-Si3N4), silicon manganese nitride, nitrided ferro manganese, and pure silicon nitride.

Applications and Characteristics of Silicon Nitride

Silicon nitride, a light grayish-white inorganic non-metallic material composed of nitrogen and silicon elements, exhibits excellent high-temperature stability and wear resistance. It finds extensive applications in steel smelting and refractory materials manufacturing. Additionally, it shows remarkable potential in wear-resistant rubber, plastics, ceramics, and both room-temperature and high-temperature sealing abrasives.

Preparation and Applications of Ferrosilicon Nitride

Ferrosilicon nitride (Fe-Si3N4) is prepared using FeSi75 iron alloy as raw material through nitridation technology and high-temperature synthesis. Compared to pure silicon nitride, ferrosilicon nitride not only demonstrates similar performance but also offers a more cost-effective solution, making it highly competitive in the market. Ferrosilicon nitride can be primarily divided into two categories: refractory ferrosilicon nitride and steelmaking ferrosilicon nitride.

- Refractory Ferrosilicon Nitride: This is a powdery substance of gray-white or tan-brown color, mainly used in large blast furnace taphole muds, with small amounts used in iron ditch materials or other amorphous refractory materials.
- Steelmaking Ferrosilicon Nitride: In granular form and also gray-white, this type is primarily used in the production of oriented silicon steel or other steels like HRB400 reinforced steel, utilizing nitrides to enhance strength.

Classification and Market Segmentation

Based on different characteristics and applications, ferrosilicon nitride can be further classified into ordinary refractory ferrosilicon nitride, high-purity refractory ferrosilicon nitride, ordinary steelmaking ferrosilicon nitride, and high-purity steelmaking ferrosilicon nitride. These classifications better meet the needs of various application scenarios, ensuring optimal performance and cost efficiency.

Applications of Silicon Manganese Nitride

Silicon manganese nitride, primarily composed of SiN and Mn, also contains mixtures of non-nitrided silicon iron, non-nitrided silicon manganese, and small amounts of other components. This gray-white granular product is mainly used as a nitrogen additive for oriented silicon steel, as well as for high-strength steel (such as HRB400) and as a nitrogen additive for casting.

Importance of Nitrided Ferro Manganese

Nitrided ferro manganese is an indispensable alloying agent for the production of special alloy steel, stainless steel, and heat-resistant steel. Typically obtained by nitriding medium to low-carbon ferromanganese, it serves as a nitrogen additive in steel refining, enhancing the steel’s strength and other mechanical properties, refining grain size, and stabilizing austenite structures.
