Fused refractory brick is a high-quality refractory material, mainly made of alumina, silicon carbide and other materials through electric melting. Fused refractory bricks have high corrosion resistance, wear resistance and high temperature resistance, and are widely used in steel, building materials and other industries. The following is a detailed introduction to the role of fused refractory bricks:

1. High temperature resistance: The main components of fused refractory bricks are alumina and silicon carbide, which have high refractoriness and can maintain stable performance at high temperatures. Fused refractory bricks can withstand high temperature environments up to 2000 °C.

2. Corrosion resistance: The corrosion resistance of fused refractory bricks is also excellent, and can withstand the erosion of corrosive substances such as strong acid and strong alkali. Therefore, it is often used in the lining of acid-resistant corrosion-resistant equipment such as leaching furnaces and distillation towers in chemical and metallurgical industries.

3. Anti-wear: Fused refractory bricks have a smooth surface, high hardness, and good anti-wear performance. They can be used for a long time in strong abrasive environments such as high-speed fluids and granular materials.

4. Wide range of applications: Fused refractory bricks are widely used in high-temperature equipment linings and thermal components in steel, building materials, and chemical industries, such as electric furnaces, converters, kilns, crucibles, and sintering machines.


In short, fused refractory brick is an excellent high-temperature refractory material, which has the characteristics of high temperature resistance, corrosion resistance and wear resistance. It is widely used in many industries such as iron and steel, building materials, and chemical industry. It is mainly used for high-temperature equipment lining and thermal components to ensure the normal operation of the equipment and prolong the service life.
