Gạch cách điện corundum crom cao cấp

Corundum Brick

We can customize your products according to your drawings or requirements. Welcome to consult us.

Characteristics:
Corundum products and corundum synthetic products are characterized with excellent thermal shock resistance, corrosion resistance and have super properties in erosion and spalling. They are the first selected super materials for glass furnaces, heating furnaces chemical kilns and metallurgic furnaces.



Application:
The bubble zircon brick are mainly used for lining of high temperature furnace and industry ceramic, electrical ceramic, petrochemical and metallurgical industries, as well as the insulation material for super high temperature furnace.
