本文就稀土对盐浴防氧化脱碳的作用进行了研究。结果表明，稀土对盐浴的校正作用具有良好的速效性和持效性，沉淀造渣能力强，可以防止酸性氧化物对工件和电极的浸蚀，是一种综合性能较好的盐浴校正剂。
In this paper, the role of rare earth salt bath anti-oxidation decarburization were studied. The results show that the correction effect of rare earth on the salt bath has a good effect and persistence, precipitation sedimentation ability, can prevent acid oxides on the workpiece and the electrode erosion, is a good overall performance of salt bath correction Agent.
