| 摘 要： | 研究了采用6000A电解槽生产镨钕合金过程中，电解温度、氧化物的利用率、电解质组成、阳极更换方式等因素对合金中碳含量的影响。结果表明，将电解温度控制在1000～1020℃之间，氧化物利用率控制在100％～104％，电解质组成（质量比）控制在NdF3：LiF=7．5：1，采用逆时针顺序更换阳极，阳极更换周期为48h，相邻两块阳极的更换时间间隔为12h，就可以将镨钕合金产品中的碳含量控制在0．03％（质量分数）以下。

| Abstract: | Abstract： Tthe effects of temperature of electrolysis, utilization ratio of oxides, electrolyte composition, anode replacement on the carbon content of Pr-Nd alloy during production process by 6000A electrolysis cell were discussed in this paper. The results show that when the electrolytic temperature is controled in rang of 1 000-1 020℃, the utilization ratio of oxides is 100%-104%, mass ratio of as the adjacent anodes every other 12 hours, the carbon content of Pr-Nd alloy can be controlled less than 0.03%. |
