Product Description

Sidewall Block For Alumina Cell, Alumina Industry Kiln Refractory Materials

Quick Detail:

1, Low permanent linear change on reheating
2, Good Thermal Shock Stability
3, High dense structure

Description:

Wear-Resistance bricks are made of raw materials such as high-grade bauxite and Australia imported zircon sand, which are melted and founded in high temperature electric furnace. It is mainly used in areas that require high abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical furnaces, the tapping platform (tapping spout) for tapping platform (tapping spout) style walking beam furnaces, and also as the interior for destructors.

Applications:

1, Sulfuric cracking furnace
2, Fibrous glass furnance
