Alumina silicon carbide brick is a kind of refractory brick made of high-aluminum vanadium material and silicon carbide as the main raw materials. This refractory brick has high refractoriness and good thermal conductivity. It also has good high temperature strength and thermal shock resistance. Moreover, Kerui’s aluminum silicon carbide bricks have been exported to more than 50 countries around the world. Contact us to buy aluminum silicon carbide bricks at a low price!
Parameter of Alumina Silicon Carbide Brick
The alumina silicon carbide bricks sold by Kerui are wear-resistant and erosion-resistant. Its sintering process is more complicated than that of high alumina bricks. Therefore, its performance is better. The following is a reference to the technical parameters of aluminum silicon carbide bricks that meet the standards of the Chinese refractory industry. Kerui also supports customers in sending kiln drawings or technical indicators of refractory bricks for customization.

Alumina Silicon Carbide Brick Protects Kilns
High alumina silicon carbide brick has better performance indicators such as load softening temperature, thermal shock resistance, wear resistance and erosion resistance than alumina refractory bricks. They are used in metallurgy, ceramics, glass, electricity, the chemical industry and other industries. Moreover, whether it is the lining of the incinerator or the furnace wall of the high-temperature melting equipment, it has good adaptability.
- Reduce the temperature of the furnace body by more than 50℃. The silica mullite brick ensures the safe operation of thermal equipment and reduces the phenomenon of the kiln body being burned red.
- Reduce energy consumption by more than 5%. The use of aluminum silicon carbide bricks can improve the thermal efficiency of the kiln, which greatly improves the benefits of the enterprise.
- Good overall performance. Its effective use volume is larger than that of composite products and has a longer wear resistance period.
Manufacturing Technology of Alumina Silicon Carbide Brick
Batching Process
The ingredients of aluminum silicon carbide bricks are high-quality high-alumina bauxite clinker particles and fine powder, silicon carbide fine powder. Then we use aluminum phosphate as a binder to fully mix them.
Molding Process
Kerui has 20 400-1000T CNC presses to press the brick body into shape. This effectively improves the quality and dimensional accuracy of the finished aluminum silicon carbide bricks.
Firing Process
It is dried and sintered in Kerui’s 168-meter high temperature tunnel kiln. The fully automatic microcomputer temperature control makes the product fired evenly and has a high yield rate. Follow our YouTube to see the overall production process.
A Cost-Effective Market Choice – Kerui Refractory
On the basis of ensuring product quality, Kerui’s alumina silicon carbide bricks are usually more affordable than similar international products. Especially for companies that purchase in bulk, Kerui can provide more attractive wholesale prices.
In addition, Kerui also flexibly adjusts its pricing strategy according to customer needs to adapt to customers of different sizes and different needs. This price advantage makes Kerui’s alumina silicon carbide composite brick a very cost-effective choice in the foreign market.
