Magmalox wear-resistant Skid rail block also called magmalox block 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.
Magmalox wear-resistant Skid rail block
are made of raw materials such as high-grade corundum, mullite Fused zirconium and so on. 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.

Applications
Electrocast wear resistant block is also called skid rail block. 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) style walking beam furnaces, and also as the interior for destructors.
