我厂电解铜的供应曾一度中断,由本省拨给一批杂铜,其戌分极为复杂(表1),而厂内又没有反射炉、电解槽等设备。但我们在党委、厂部的支持下,进行了设备极为简陋的吹氧精炼,前后共进行了六次试验,获得了成功。这样有力的打破了没有设备不能精炼的迷信,同时也提供了人民公社、小型企业办铜精炼厂的条件。根据分析结果,纯度已达99．20%,用来配制合金制造机械工业上的铜铸件,质量是有保证的,同时也可以使珍贵的电解铜应用到更需要的电力工业上去。
The supply of electrolytic copper in our factory was once interrupted by a batch of miscellaneous bronze allocated by our province. The extremely fragile nature of the copper in our factory (Table 1), but there is no equipment such as the reflecting furnace and electrolyzer in the factory. However, with the support of the party committee and the factory department, we conducted a very simple process of oxygen blowing and refining, and we succeeded in carrying out six tests before and after. This has effectively broken the superstition can not be refined equipment, but also provides people’s communes, small businesses do copper refinery conditions. According to the analysis results, the purity has reached 99.20%, which is used to formulate alloy manufacturing copper castings in machinery industry, the quality is guaranteed, and the precious electrolytic copper can also be applied to the more needed power industry.
