中文摘要: 运用数值模拟软件COMSOL研究了不同电极插入深度下3 kA钕电解槽的电热场。结果表明,电解槽槽电压随着阴阳极插入深度的递增而降低,槽体的整体温度随着阴阳极插入深度的增加而下降。结合实际生产经验与本研究结果,认为电极插入深度220 mm比较适宜,且整个电解过程相对稳定,能够达到槽体电压、温度分布等方面的要求。
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.
