去年八月份我省召开了轴承工作会议,推广稀土球铁滚珠轴承,并要求试制粉末冶金滚珠轴承。我厂接受这个任务后,成立了“三结合”试制小组,前后搞了三个多月,试验了十多种配方,都没有达到要求。今年初,地区科办、工业研究所同志向我们介绍了“优选法”,一月二十九日《南方日报》发表了《大家都来推广、应用优选法》的短评,报导了广州、江门、佛山等市推广、应用“优选法”的成果。因此,我们开始应用“优选法”进行试验,仅试验了五次,就找到较好的配比、配方,并试制出一小批206~#滚珠轴承。
In August last year, the province held a meeting on bearing work to promote rare-earth ball-iron ball bearings and requested trial production of powder metallurgy ball bearings. After accepting this task, our factory set up a “three-in-one” trial team. After more than three months, we tested more than a dozen formulas and failed to meet the requirements. Earlier this year, the comrades of the Regional Branch and the Institute of Industry introduced the “Optimization Law” to us. On January 29, the “Nanfang Daily” published a short commentary on “Everybody has come to promote and apply the optimization method”, reporting on Guangzhou, Jiangmen and Foshan. Cities to promote and apply the results of the “Optimization Law.” Therefore, we began to use the “optimization method” for testing, only to test five times, to find a good ratio, formula, and trial production of a small batch of 206 ~ # ball bearings.
