Recrystallized Silicon Carbide Ceramic Roller For Kiln

Recrystallized silicon carbide ceramic roller for kiln is a high temperature ceramic roller used in high temperature industrial equipment such as sintering and drying furnaces. Recrystallized silicon carbide ceramic roller for kiln is made of high purity silicon carbide powder and is treated with high temperature sintering and recrystallization, giving it extremely high temperature resistance, corrosion resistance and wear resistance. Compared with the traditional roller material, Recrystallized silicon carbide ceramic roller for kiln has longer service life and higher production efficiency, and can greatly reduce the production cost and maintenance cost.
