Fire Resistant Brick for Steel Reheating Furnace
Specifications
Fused Cast Skid Rall Block
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, 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
