Industry Pain Points: The Struggle in High - Temperature Environments

In the high - temperature environments of non - ferrous mines, metallurgical blast furnaces, and the ceramic industry, finding the right refractory material has always been a challenge. Traditional refractory materials often fail to meet the high - intensity, high - temperature, and harsh chemical corrosion requirements. For example, in non - ferrous mines, high - temperature smelting processes can cause rapid wear and tear of ordinary refractory bricks, leading to frequent equipment maintenance and replacement, which not only increases costs but also reduces production efficiency. According to industry statistics, nearly 30% of production interruptions in high - temperature industries are due to the failure of refractory materials.

Core Features of Silicon Nitride Bonded Silicon Carbide Bricks

Silicon nitride bonded silicon carbide bricks stand out with their core features. Firstly, they have high strength. Compared with traditional refractory bricks, their compressive strength can be up to 50% higher, which means they can withstand greater pressure in high - temperature environments without deformation or cracking. Secondly, their excellent thermal conductivity is a significant advantage. With a thermal conductivity of about 20 - 30 W/(m·K), it can quickly transfer heat, ensuring uniform temperature distribution in the furnace and improving energy efficiency. In addition, their outstanding thermal shock resistance allows them to withstand rapid temperature changes without damage. For example, they can maintain their integrity after experiencing temperature differences of up to 800°C in a short time, while traditional refractory bricks may crack or even break under the same conditions.

Specific Application Scenarios and Values

Non - Ferrous Mines

In non - ferrous mines, silicon nitride bonded silicon carbide bricks are used in high - temperature smelting furnaces. Their high strength and corrosion resistance can effectively resist the erosion of molten metal and slag, extending the service life of the furnace. For example, in a copper mine in South America, after using silicon nitride bonded silicon carbide bricks, the furnace maintenance cycle was extended from 3 months to 6 months, significantly reducing maintenance costs and increasing production efficiency.

Metallurgical Blast Furnaces

In metallurgical blast furnaces, these bricks can improve the thermal efficiency of the furnace. Their good thermal conductivity helps to transfer heat evenly, reducing energy consumption. According to a steel plant in Europe, after replacing traditional refractory bricks with silicon nitride bonded silicon carbide bricks, the energy consumption per ton of steel decreased by about 15%, achieving significant cost savings.

Ceramic Industry

In the ceramic industry, the high - temperature firing process requires refractory materials with excellent thermal shock resistance. Silicon nitride bonded silicon carbide bricks can ensure the stability of the firing process, reduce product defects, and improve the quality of ceramic products. A well - known ceramic factory in Asia reported that after using these bricks, the defective rate of ceramic products decreased from 10% to 3%.

Laboratory Test Results

"Our laboratory tests have shown that silicon nitride bonded silicon carbide bricks have excellent performance in high - temperature resistance, corrosion resistance, and thermal shock resistance," said a senior researcher from an international refractory materials laboratory. The test results showed that after 1000 hours of continuous high - temperature testing at 1500°C, the weight loss of silicon nitride bonded silicon carbide bricks was less than 5%, while that of traditional refractory bricks was as high as 20%.

International Market Recognition and Domestic Customer Cases

Silicon nitride bonded silicon carbide bricks have gained wide recognition in the international market. In Europe and the United States, they are widely used in high - end metallurgical and ceramic industries. In Asia, countries such as Japan and South Korea also import a large amount of this product. In the domestic market, more than 10 domestic leading enterprises in the non - ferrous metallurgy and ceramic industries have used our products, achieving significant cost - reduction and efficiency - improvement results. For example, a leading non - ferrous metallurgy enterprise has increased its production efficiency by 20% after using our products.
