Alumina decomposition tank is an important equipment for the oxidation processing of aluminum metal products. The thermal performance of aluminum production under the mutation of heat transmission in the alumina decomposition tank is analyzed to improve the processing status. Construction of alumina decomposition tank device structure model, mainly by the thermostatic cooling water system, valves, pipe pumps and rotors. The experimental data of the thermal state of the aluminum electrolysis were analyzed and fitted by the technical parameters. The thermal behavior of the outer wall of the aluminum heat transfer surface at 55, 60, 80 ℃ were analyzed experimentally. The experimental results show that, By this method, the aluminum electrolysis under the abrupt change of heat transfer in the alumina decomposition tank has better heat cycle utilization performance and higher processing efficiency.
