近年来,我国陆续建立了不少可控气氛热处理炉,可控气氛淬火、渗碳自动线,由于这些设备连续作业,处理量大,特别是一次淬入量增加,普通光亮粹火油无论是淬硬性或淬透性都难以满足工艺要求。为此,大连石油七厂研究所与天津热处理工艺研究所协作,进行了快速光亮淬火油的研制。根据热处理生产的需要,所研制的快速光亮淬火油,其冷却特性、光亮度和热氧化 In recent years, many controllable atmosphere heat treatment furnaces have been established in our country. The controllable atmosphere quenching and carburizing automatic lines have been widely used in these industries because of their continuous operation and large capacity. In particular, Hard or hardenability are difficult to meet the process requirements. To this end, the Dalian Institute of Petroleum seven plants and Tianjin Institute of heat treatment technology collaboration, conducted a rapid bright quenching oil research. According to the needs of heat treatment production, the rapid development of bright quenching oil, its cooling characteristics, brightness and thermal oxidation
