The invention discloses a copper rod processing technology, comprising the following steps: A. pre-processing waste copper; B. putting the pre-treated waste copper in a melting furnace for pre-melting, and then slag sloughing; C. Continue to heat up the melting furnace after adding purification flux to the molten liquid after the slag; D. pour the purified molten liquid into the pre-made copper rod mold; E. rapidly cool the copper rod mold to normal temperature and then open it. F. Finally, spray a protective coating on the surface of the copper rod, the copper rod processing technology adopted in the present invention is simple to operate, and the obtained copper rod has high purity, good hardness, is not easy to be oxidized and deformed, and has a long service life. |
