高速钢车刀经氯化盐分级淬火后.为便于观测变形,必须清除表面盐渍.我厂原采用刮盐方法.盐渍不易除净;工件热.工人劳动条件差;生产效率低.从1966年在上海工具厂开始试验采用了水爆清盐法,使用效果较好。 High-speed steel turning knife after chloride salt quenching. In order to facilitate the observation of deformation, the surface must be cleaned of salt. I plant the original use of salt scraping method. Salt is not easy to remove the net; the workpiece is hot. Poor working conditions of workers; In 1966, the Shanghai Tool Factory started the experiment using water-clearing and salt-clearing method, and the effect was better.
