Simulation Analysis on the Effect of Cathode and Anode Center Distance on Electrothermal Field of 15 kA Rare Earth Electrolytic Cell AITranslate
Abstract AITranslate
In order to solve the problem of ununiform thermal field distribution in rare earth electrolytic cell,a three-dimensional model of 15 kA rare earth electrolytic cell was established and the distance between anode and cathode of the model was adjusted. COMSOL software was used to simulate and analyze the electrothermal fibld in the electrolytic cell with different center distance between anode and cathode,to obtain the distribution of the three-dimensional electrothermal field in the electrolytic cell. The results show that with the increase of cathode and anode center distance, the high temperature isothermal surface in the electrolytic cell constantly shift towards the center of the cell, the highest isothermal surface of the right cathode gradually narrows to fall off the anode, and the highest isothermal surface near the left cathode constantly extends and shifts towards to the cell center. The maximum current density in the electrolytic cell has no obvious change regularity with the increase of cathode and anode center distance, reaching the maximum value at the center distance of d=33 mm and meanwhile obtaining the most uniform distribution of high temperature isothermal surface. The optimal distance between anode and cathode in the electrolytic cell is 33 mm.
