Effect of Cell Structure on Thermoelectric Field in 5 kA Scale Inert-anode Aluminum Reduction Cell
Two cell structures of 5kA scale inert-anode aluminum reduction cell were put forward and the thermoelectric field was calculated using finite element method with common cathodes and graphitized cathodes,respectively.The results indicate that the heat is not balanced for both cell structures under initial conditions but it can be balanced by intensifying current,the anode-cathode distance and heat preservation.The cell with graphitized cathodes needs more energy to achieve heat balance but it can assure more reasonable temperature distribution in the cathodes.The cell structure 2 is a little better than the cell structure 1 considering the thermoelectric field distribution only.
