Grinding heavy medium ferrosilicon nitride

Excellent oxidation resistance and corrosion resistance: Silicon nitride iron has high thermal stability and chemical stability, and can resist the erosion of various high-temperature slag, acid and alkali solutions and other corrosive substances, ensuring the service life of the material.

Excellent high-temperature strength and wear resistance: Silicon nitride iron can maintain high strength and wear resistance even at high temperatures. It can resist the friction and impact from slag and materials, ensuring that the furnace lining remains intact.

Low thermal expansion coefficient: The thermal expansion coefficient of silicon nitride iron is relatively low, which enables it to adapt to the thermal expansion and contraction caused by temperature changes, thereby reducing the cracking and peeling of the furnace lining materials.

Excellent thermal conductivity and insulation performance: The thermal conductivity of silicon nitride iron is high, enabling it to transfer heat, lower the furnace temperature, and reduce energy waste. At the same time, it also has excellent insulation properties, which can reduce heat loss and the heat loss of the furnace lining materials.

In conclusion, silicon nitride iron, as a refractory material, possesses outstanding advantages such as excellent oxidation resistance and erosion resistance, good high-temperature strength and wear resistance, low thermal expansion coefficient, good thermal conductivity and insulation properties. These advantages have enabled silicon nitride iron to be widely used in high-temperature industrial fields, such as in the furnace linings, nozzles, and hearths of industries like steel, glass, ceramics, and non-ferrous metals, for the protection and support of key parts. Additionally, silicon nitride iron can also be used for the maintenance and repair of high-temperature kilns, extending their service life and improving energy utilization efficiency.
