| Abstract: |
| Electric-thermal field of 3 kA neodymium electrolytic cell was numerical simulated with software COMSOL under different insertion depth of electrode. The results show that both cell voltage and overall temperature of cell drop with increase of electrode insertion depth. With actual production experience and results of this research into consideration, the suitable electrode insertion depth is 220 mm. The condition of whole electrolysis process is relatively stable, and meets requirements of voltage and temperature distribution. |
