Aluminum smelting equipment Reflector, contact with aluminum liquid lining, generally use Al203 content of 80 ~ 85% of the high alumina refractory masonry, melting high purity metal aluminum, the use of mullite refractory bricks or corundum bricks. In the hearth slopes and places such as waste aluminum and other easy to erosion and wear parts, silicon nitride can be combined with silicon carbide refractory bricks. Flow aluminum and aluminum mouth and other parts of the aluminum solution is serious, generally used since the combination or silicon nitride combined with silicon carbide refractory bricks. Also useful zircon tungsten refractory tiles ashamed lining. Out of the aluminum mouth blockage, the use of vacuum cast refractory fiber cone effect is better. Do not touch the aluminum solution of the lining, the general use of high alumina refractory bricks, high alumina refractory castable or refractory plastic. The insulation layer uses light brick, light refractory castable and refractory fiber products. Flow aluminum trough of the lining, the general use of silicon carbide refractory bricks, can also be used fritured silicone brick prefabricated block.
