Fused Cast Skid Rail Block are made of high-grade bauxite and Australia imported zircon sand，which are through special casting process by melting the raw material in the mold with high temperature, then cooling and solidification. It has dense structure，high abrasion resistance, strong crushing strength, high temperature resistance, good thermal shock resistance, etc.

Application: It is mainly used in areas that require high abrasion and high temperature,such as gliding rail bricks in steel pusher metallurgical furnace，the tapping platform(tapping spout) for tapping platform(tapping spout) style walking beam furnace, and also as the interior for destructors.

Its chemical and physical index is as below:
