我厂原青铜砂轮基体,采用45号钢切削加工制造成功,生产率低,原材料浪费大。为了适应生产发展的需要,我们自制了一台工频电炉,用废基体,料头等经过精密铸造加工成基体满足了生产的需要,这样不仅做到了废料回收,而且解决了原材料不足的矛盾。每年可为国家节约工时1000小时。 I plant the original bronze wheel base, using 45 steel cutting successful manufacturing, low productivity, waste of raw materials. In order to meet the needs of the development of production, we made a power frequency electric furnace, using waste matrix, the first such as precision casting into the substrate to meet the production needs, so that not only did the waste recovery, but also solve the contradiction between lack of raw materials. Every year for the country to save 1000 hours working hours.
