在采用盐浴炉进行工件的淬火时,盐浴炉中的氯化钡是有剧毒的盐。为保证工件淬火质量,在盐浴炉工作过程中要不断地从炉中清除炉渣。经化学分析,在炉渣中还含有50％左右的氯化钡。过去,对这种炉渣我们无法处理,经过无产阶级文化大革命,特别是在批林批孔运动中,在党委领导下,成立了三结合的“三废治理小组”,对氯化钡盐浴炉渣的处理进行了多次试验,终于找到了用水淬法来处理炉渣,并回收氯化钡。经过两年来的生产实践,证明用这种方法处理氯化钡盐浴炉渣是可行的,不仅解决了对环境污染问题,还能回收大量的氯化钡。现将水淬法处理氯化钡炉渣的情况介绍如下。
In the salt bath furnace for quenching the workpiece, the barium chloride salt bath furnace is a highly toxic salt. To ensure the quality of the workpiece quenching, salt bath furnace in the process of continuous removal of slag from the furnace. After chemical analysis, the slag also contains about 50% of barium chloride. In the past, we could not handle this type of slag. After the Great Proletarian Cultural Revolution, especially in the campaign of criticizing Lin and Biao, under the leadership of the Party Committee, we set up a triple combination of “three wastes governance group” to treat barium chloride salt bath slag Several tests were conducted on the treatment, and finally the water quenching method was finally used to treat the slag and the barium chloride was recovered. After two years of production practice, it is proved that it is feasible to treat barium chloride salt bath slag in this way, which not only solves the problem of environmental pollution but also recycles a large amount of barium chloride. Now water treatment of barium chloride slag situation is described below.
