195S柴油机是我厂今年刚投入生产的产品。在任务重,时间紧,设备少的情况下,为了坚决完成国家计划,响应厂党委提出的“坚持以批林整风为纲,抓大事,促大干,鼓干劲,挖潜力,努力实现改型不减产”的号召,热处理车间革命职工大胆地提出了球墨铸铁曲轴高频淬火的新课题。于五月底着手进行球墨铸铁曲轴高频淬火试验性生产。由于过去从未实践过, 经验不足,产品质量不稳定,有时有淬火裂纹或另件变形问题发生。不久华罗庚同志带领的推广优 195S diesel engine is our factory just put into production this year. In order to resolutely complete the state plan, in the light of the heavy tasks, the tight schedule and the small equipment, we should respond to the principle of “adhering to the policy of” Not cut production "call, heat treatment workshop workers boldly raised the ductile iron crankshaft induction hardening of new topics. At the end of May proceed with the pilot production of ductile iron crankshaft high-frequency quenching. Since the past has never been practiced, lack of experience, product quality is not stable, and sometimes there are quenching cracks or other parts of the deformation problems occur. Comrade Hua Loeng soon led the promotion of excellence
