Influence of Temperature Distribution on Products Quality in 3KA Rare Earth Electrolytic Cell

Abstract:

An investigation was carried out into temperature distribution in 3KA rare earth electrolytic cell and changes of products quality in neodymium electrolysis from a factory in China, The results show that the different temperature distributions have direct effects on the neodymium products quality. In same production cycle, the cell voltage of electrolytic cell is stable and curre rocessing before discharging bascially stays the same; In different cycles, temperature distribution not always alike, mainly reflected in lateral distribution of temperature in electrolytic cell, one form is temperature gradually increased from cathode to anode, and the anode temperature is highest; another is temperature declined then elevated again, anode temperature is slightly higher than the temperature of cathode. The second distribution is benefit for improve the quality of products.
