Numerical simulation and optimization of thermal field of aluminum reduction pot after graphitization of cathode carbon block
The graphitization of cathode carbon block is an important tool of aluminum smelters for upgrading currently.Firstly,the thermal field of the graphitized cathode carbon block aluminum reduction pot slice model was simulated numerically by COMSOL simulation software,and it was found that the temperature distribution of the graphitized cathode carbon block was uniform,with a maximum temperature of 933.05℃.Secondly,the energy balance test was carried out after the application of graphitized cathode carbon blocks to an aluminum smelter,and the total energy output accounted for 97.22％of the total input,the input and output were relatively balanced.Finally,the thermal field was optimized by increasing the thickness of the anode covering material and adding nano insulation materials at the bottom and sides,the insulation layer thickness was 96 mm,with an increase of 1.43℃ per millime-ter,and the thermal insulation effect was the best.
