Non stick aluminum castable is a kind of high purity low cement castable specially developed for smelting aluminum industry. Several additives were added to the castable to resist non sticking aluminum liquid. The utility model has the advantages of high bulk density, high strength and no wetting property of aluminum liquid. Suitable for aluminium melting furnace hearth, a furnace wall, a furnace door frame, aluminum groove and other parts. It can significantly reduce the growth of corundum and the penetration of molten metal.
