Anti-seepage high alumina bricks for aluminum melting furnace


Anti-seepage high-alumina bricks are made of high-quality high-alumina chamotte as the main raw material, formed by high pressure and fired at high temperature. This product can effectively prevent the penetration of molten aluminum, and has good wear resistance and thermal shock resistance. It is the preferred lining material for aluminum melting furnaces.
