【摘要】 根据目前中国稀土电解槽生产的实际状况,以8 k A稀土电解槽为研究对象,通过在某工厂实习期间实际测量的电解生产数据和实际生产情况,试图找出对电解生产结果产生重要影响的工艺因素。根据工厂现有设备和条件,确定了对试验结果影响较大的5个因素:电解电压、电解温度、反应时间、阴阳极距、加料频率。围绕这些因素进行正交分析,找出其对生产结果影响重要性的主次关系并确定电解生产的最佳因素组合。结果表明,电解温度在电解过程中起着关键作用,温度把控不好导致电流效率不高且耗能严重,生产效率波动,按最佳工艺参数标准生产的电解槽各方面指标均有了明显提高。更多还原

【Abstract】 According to the current situation of rare earth electrolytic cell production in China,taking the 8 k A 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.更多还原
