[0002] Scrap copper is a general term for waste products and scrap materials, which mainly come from three aspects: waste products and scrap materials generated during copper smelting; copper in waste products and scrap materials generated during various mechanical processing processes; copper in old and scrapped instruments, meters, tools and machinery and equipment during use, etc.

[0003] In the authorized patent document with the announcement number CN217251560U, a waste copper continuous casting and rolling low-oxygen bright copper rod production device is disclosed, and its technical solution is: it includes a bottom plate, the top of the bottom plate is fixedly connected to a shell and a continuous rolling mill, one side of the continuous rolling mill is fixedly connected to a channel, one end of the channel extends to the inside of the shell, a through groove is opened on one side of the shell, a copper rod body is arranged inside the continuous rolling mill, one end of the copper rod body passes through the through groove and extends to the outside of one side of the shell, an auxiliary mechanism is arranged inside the shell to control the operation of the drive assembly, so that the cylinder can be rotated, so that the nozzle can spray water around the copper rod body, so that there will be no cooling dead corner when cooling the copper rod body, so that the copper rod body can be cooled more evenly, and the cooling efficiency can be increased at the same time, thereby solving the problem that the existing production device has poor cooling effect and uneven cooling when cooling the copper rod body, which leads to low cooling efficiency.

[0004] When the above device is implemented, cracks may appear on the surface of the low-oxygen copper rod after continuous casting and rolling, which is mainly affected by the oxygen content of the copper rod. When the oxygen content of the copper rod is too high, for example, when it is greater than 600ppm, a certain amount of Cu2O will be produced in the copper rod structure, resulting in an increase in the hardness of the copper rod. During torsion or cold working, uneven deformation may occur around these oxides, causing cracks in the copper rod, so that when the copper rod body moves in the connecting plate and water is sprayed inside the cylinder, water will seep out from the cracks between the connecting plate and the copper rod, which will cause water to appear inside the shell, the channel and the rolling machine, causing mechanical damage.
