Silica-corundum compound brick
Description:
Low thermal conductivity silica-corundum compound bricks rely on the advantages of novel multilayer composite structures and are widely used in large and medium-sized rotary kiln transition zones, decomposition zones and other parts. Its excellent abrasion resistance, anti-stripping performance and thermal shock resistance effectively improve the operation cycle of the kiln. The multi-layer composite structure of the product can effectively reduce the temperature of rotary kiln body, and alleviate the problems of high temperature, large temperature difference, and no kiln skin protection in the transition zone of the rotary kiln. It is the first choice for large and medium-sized rotary kiln linings.
Advantage:
Excellent abrasion resistance, anti-stripping performance, thermal shock resistance, low thermal conductivity
Application:
Transition zone, decomposition zone of large and medium-sized rotary kiln
