Abstract：According to the current situation of rare earth electrolytic cell production in China， taking the 8 kA rare earth electrolytic cell as the research object， the important factors which influence the result of electrolysis production was tried to find out through the actual production data and production situation in a factory practice. According to the existing equipments and conditions in the factory， five factors affecting the experimental results were determined， including： electrolytic voltage， electrolytic temperature， reaction time， polar distance and feeding frequency. Based on the orthogonal analysis of these factors， the primary and secondary relation of the influence on the production results were given out， and the optimum combination of factors was determined. It is found that the temperature plays a key role in the process of electrolysis. Bad temperature control leads to fluctuating production efficiency， low current efficiency and serious energy consumption. According to the best process parameters， all the indexes of the electrolytic cell are improved obviously.
