Specifications

Used in skid rail furnace,hearth furnece,gliding rail bricks,stell pusher furnace

Wear-Resistance bricks are made of raw materials such as high-grade bauxite and Australia imported zircon sand.

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 style walking beam furnaces, and also as the interior for destructors
