机车车辆用的各种螺旋压缩弹簧的淬火,几十年来都是采用油作冷却剂。虽然苏联有些工厂已经采用水作弹簧淬火的冷却剂,可是我们一直不敢采用。经过伟大的整风运动,工人们干劲冲天,敢想敢干,技术人员和哈工大的同学密切地同工人配合,在领导的大力支持下,对弹簧的水淬做了一系列的试验,并在今年五月份正式大批投入生产。四个月来的生产实践证明:大量生产簧条直径较大(φ25公厘以上)的螺旋弹簧,采用“卷制、调整、淬火”的一次加热和水淬的新工艺,给生产带来了很大的好 Quenching of various helical compression springs used in rolling stock has been using oil as a coolant for decades. Although some factories in the Soviet Union have used water as spring-hardened coolant, we have not dared to adopt it. After great rectification movement, the workers are energetic and daring to dare to do it. Technicians and students from Harbin Institute of Technology closely cooperate with the workers. With the strong support from the leaders, a series of tests have been conducted on the water quenching of springs. In May a large number of officially put into production. Four months of production practice has proved that mass production of coil spring with larger diameter (φ25 mm above), the use of “rolling, adjusting, quenching” a heating and water quenching new technology, brought to the production Very good
