我厂自1986年7月从日本引进网带式炉热处理生产线。正式投产以来,我们经过反复对比应用试验,一直采用国产的1号分级淬火油来代替日本的303淬火油作为淬火介质,取得了显著的社会经济效益。 1.1号分级淬火油简介 1号分级淬火油是由北京机电研究所和上海润滑油厂共同研制的。研制单位在油品配方、性能测试、工艺试验及应用试验等方面取得了满意的结果。从1985年开始在轴承、齿轮等热处理厂点进行推广应用。分级淬火又称为热油淬火,一般要求淬
I plant since July 1986 from Japan to introduce net belt furnace heat treatment production lines. After formally put into operation, we have repeatedly compared the application of tests, has been using domestic grade 1 quenching oil instead of Japan’s 303 quenching oil as a quenching medium, and achieved significant social and economic benefits. Grade 1.1 quenching oil Introduction Grade 1 quenching oil by the Beijing Institute of Electrical and Shanghai Lubricants jointly developed. The research institutes have achieved satisfactory results in oil formulation, performance test, process test and application test. From 1985 onwards, bearings, gears and other heat treatment plant sites for promotion and application. Grade quenching, also known as hot oil quenching, generally require quenching
