“化学世界”1962年第10期董子成同志所写“氰化热处理盐浴的分析方法”一文,通过我们的实际工作,发现该文存在一些问题,特提出来讨论。根据资料介绍及结合我厂热处理车间生产情况,高温氰化盐浴(液体渗碳)的原始组成为:氰化钠6～13%,氯化钡70～80%,氯化钠8～10%,其中氰化钠是盐浴的主要成分(氰化剂),氯化钡、氯化钠(碱金属及碱土金属的氯化物)是盐浴的中性成分,至于碳酸钠、碳酸钡(碱金属及碱土金属的碳酸盐)是盐浴中的 “Chemical World” in 1962 No. 10 written by Comrade Dong Zicheng “Cyanide heat treatment salt bath analysis,” a text, through our practical work, found that the article there are some problems, especially put forward to discuss. According to the information and the combination of our plant heat treatment plant production, the high temperature cyanide salt bath (liquid carburizing) of the original composition: 6 ~ 13% of sodium cyanide, barium chloride 70 ~ 80%, sodium chloride 8 ~ 10% , Of which sodium cyanide is the main component of the salt bath (cyanating agent), barium chloride, sodium chloride (alkali metal and alkaline earth metal chloride) is a neutral salt bath, as sodium carbonate, barium carbonate Metal and alkaline earth metal carbonates) are in salt baths
