山西柴油机厂蒋学富高级工程师在由机械电子部兵器科学研究院及中国兵工学会金属材料学会联合举办的1988年(在无锡召开)的学术年会上介绍了他对用65Mn钢油淬钢丝制造气门弹簧的制造工艺、钢丝质量及性能的分析情况的试验结果。 65Mn冷拔钢丝除制造各类汽油发动机和柴油发动机的气门弹簧外,还广泛地运用于各类机电产品中。此类钢丝在钢厂生产中有两种热处理制度:一种是油中淬火,即钢
Shanxi Diesel Engine Factory Jiangxue Fu Senior Engineer in the Department of Mechanical and Electronic Weaponry Academy of Sciences and the Chinese Academy of Ordnance Metals and Materials Society jointly held in 1988 (held in Wuxi) annual meeting of his academic year with 65Mn steel quenched steel wire manufacturing valve Spring manufacturing process, wire quality and performance analysis of the test results. In addition to the manufacture of various types of gasoline engine and diesel engine valve spring, 65Mn cold-drawn steel wire is widely used in various types of mechanical and electrical products. There are two types of wire in the production of steel heat treatment system: one is oil quenching, that steel
