Silicon nitride bonded silicon carbide bricks, an advanced product in the refractory materials field, have been widely used in non - ferrous mines, metallurgical blast furnaces, and the ceramic industry. Their unique properties make them stand out in the market.
These bricks are known for their high strength, excellent thermal conductivity, remarkable thermal shock resistance, and outstanding corrosion resistance. Independent laboratories have conducted strict tests on their performance. For example, in terms of strength, the compressive strength of silicon nitride bonded silicon carbide bricks can reach up to 300 MPa, which is much higher than that of ordinary refractory bricks. In terms of thermal conductivity, it can reach about 20 W/(m·K), ensuring efficient heat transfer in high - temperature environments.
In non - ferrous mines, the harsh environment requires refractory materials with high resistance to wear and corrosion. Silicon nitride bonded silicon carbide bricks have proven to be a perfect fit. A well - known non - ferrous mining company in South America used these bricks in their smelting furnaces. Before using these bricks, they had to replace the refractory lining every 6 months due to severe wear and corrosion, with an annual maintenance cost of about $500,000. After switching to silicon nitride bonded silicon carbide bricks, the replacement cycle has been extended to 2 years, and the annual maintenance cost has been reduced to $150,000, a significant cost - saving of 70%.
Metallurgical blast furnaces operate under extremely high temperatures and complex chemical environments. The high thermal shock resistance and corrosion resistance of silicon nitride bonded silicon carbide bricks are crucial for their long - term stable operation. A large - scale steel mill in Europe adopted these bricks in its blast furnace. The data shows that the thermal shock resistance of these bricks allows the blast furnace to withstand rapid temperature changes without cracking. This has increased the overall production stability of the blast furnace by 30%, reducing the number of unplanned shutdowns from 10 times a year to 3 times a year.
More than 80% of the production of silicon nitride bonded silicon carbide bricks is exported to more than a dozen countries and regions in Europe and America. Large - scale mining and metallurgical enterprises at home and abroad have highly recognized their performance. This wide - spread recognition is not only due to their excellent performance but also because of the strict quality control and continuous R & D efforts of the manufacturers.
Silicon nitride bonded silicon carbide bricks offer a reliable solution for non - ferrous mines and metallurgical blast furnaces. Their excellent performance can help enterprises achieve safe and stable equipment operation and maximize cost - effectiveness.
