根据一机部1976—1977年热处理行业活动计划,1976年11月29日至12月4日在杭州召开了淬火介质座谈会。会上交流了近几年来淬火介质的研制和生产应用情况。与会单位认为,合成淬火剂、聚醚水溶液、氯化钙水溶液等淬火介质的应用,以及光亮淬火油和真空淬火油的研究工作,对提高机械产品的热处理质量、改善劳动条件和发展我国淬火介质系列均具有重要作用。为了统一目前各单位所用的淬火介质冷却速度测试方法,推动我国淬火介质研究工作的进行,会议就此进行了专题讨论,拟订
According to a unit of 1976-1977 heat treatment industry activity plan, November 29, 1976 to December 4, held in Hangzhou quenching media forum. At the meeting exchanged in recent years the development of quenching medium and production applications. The participants believe that the application of quenching agent, polyether aqueous solution, calcium chloride solution and other quenching medium, as well as bright quenching oil and vacuum quenching oil research work to improve the quality of heat treatment of mechanical products, improve working conditions and the development of China’s quenching medium Series have an important role. In order to unify the current quenching medium used by various units cooling rate test methods to promote the research work of China’s quenching medium, the meeting conducted a thematic discussion on this
