Comparison of Electric Heating Field Simulation for Aluminum Electrolysis Cells at Different Aluminum Horizontal Heights
The aluminum horizontal height is an important indicator in the aluminum electrolysis process,and an appropriate aluminum level can maintain a good physical field inside the cell to ensure stable production.Therefore,finding the appropriate aluminum horizontal height is crucial for the optimal operation of the cell.SOLIDWORKS modeling software was used to draw four sets of 350 kA aluminum electrolysis cells with different aluminum levels in this paper.Through COMSOL simulation software,the electric and thermal fields of the four sets of different aluminum electrolysis cells were simulated and compared with the on-site test data of a certain factory s 350 kA electrolysis cell,verifying the accuracy of the simulation.It was found that with the continuous increase of aluminum level,the potential,current density,and overall temperature inside the electrolytic cell all showed a downward trend.By comparing the electric and thermal fields,it is believed that the optimal aluminum level for a 350 kA electrolytic cell is in the range of 20-22 cm,with a pressure drop of 3 630-3 810 mV and a high temperature inside the cell of about 950 ℃.
