公司各轧钢厂的轧钢铁鳞(即氧化铁皮),原来是一种工业废料,每年有数万吨。我们为了大搞综合利用,贯彻伟大领袖毛主席的光辉的“九·一三”指示,把铁鳞作为生产轴承的原料,这样不但处理了工业废物,而且制成了7315滚动轴承,使它直接为钢铁生产服务。这种轴承已安装在烧结台车上试用了几个月,运转情况良好,目前正在成批生产。实物照片如图1所示。现将生产工艺叙述如下: Rolling steel scales (ie, iron oxide scale) at various rolling mills in the Company turned out to be an industrial waste with tens of thousands of tons per year. In order to promote comprehensive utilization and carry out the brilliant “September 13” instruction of the great leader Chairman Mao, we used the iron scale as the raw material for bearing production. This not only handled the industrial waste, but also made the 7315 rolling bearing directly Steel production services. This bearing has been installed in the sintering trolley trial of a few months, running in good condition, is currently in mass production. Real photo shown in Figure 1. Now the production process described as follows:
