The high-temperature kilns used in the production process of metal aluminum include (rotary kiln), (fluidized flash roasting furnace), (circulating fluidized bed roasting furnace), (suspended roasting furnace), (tank calcining furnace), ( Carbon roasting furnace), (molten salt electrolytic cell, (aluminum melting furnace), etc.
The alumina roasting process is completed under high temperature and high speed conditions. At the same time, due to the high hardness and good fluidity of the alumina materials processed, there are very strict requirements for the quality of alumina products. Any impurities in the lining materials will not be mixed. Directly affects the performance of the product, so refractory materials are required to meet the following conditions (high temperature resistance), (wear resistance), (high strength), (good thermal stability), (good integrity), (strong sealing).
