Embodiment 1

[0022] A method for improving the surface quality of 8mm-diameter low-oxygen bright copper rods is improved on the basis of the traditional 8mm-diameter low-oxygen bright copper rod production process, which mainly includes batching, smelting, casting, rolling, cleaning, drying, coating Wax and packaging processes, wherein the following processes are improved:

[0023] a. Rolling: The electrolytic copper raw material is smelted into molten copper and then cast. After casting, a slab is obtained. Before the edge milling machine, a scoring machine with four corners of the slab is installed, and the slab passes through the four corners of the slab. After the initial edge milling of the scoring machine, the edge milling machine is officially milled, and then the rough rolling and the finishing rolling are respectively carried out on the rough rolling mill and the finishing mill. During the rolling process, a high-pressure dephosphorization pump is set to pump out the emulsion and ...

Embodiment 2

[0028] The difference between embodiment 2 and embodiment 1 is:

[0029] In the sedimentation system, there are three sedimentation tanks, and each sedimentation tank is provided with three sedimentation chambers.

[0030] In the rough rolling process, the mass fraction of alcohol in the rough rolling emulsion is 0.5%, the oil mass fraction is 1.0%, and the pH value of the rough rolling emulsion is 8.0-9.0; The alcohol mass fraction in the rolling emulsion is 1.5%, the oil mass fraction is 2.0%, the pH value of the finishing rolling emulsion is 8.9-9.0, and the temperature of the rough rolling emulsion and the finishing rolling emulsion are both controlled at 45-47°C. The mass fraction of alcohol in the cleaning solution in the cleaning process is 2.5%, the pH value of the cleaning solution is between 8.5-9.0, and the temperature of the cleaning solution is controlled at 32-34°C; in the drying process, the compressed The pressure of the air is 0.6MPa; the concentration of the...

Abstract

The invention discloses a method for improving the surface quality of a low-oxygen light copper rod with the diameter of 8mm. The method is improved on the basis of a traditional production process of the low-oxygen light copper rod with the diameter of 8mm. The method comprises the following procedures of preparing materials, smelting, casting, rolling, washing, drying by blowing, coating wax and packaging, and is characterized in that the procedures of rolling, washing, drying by blowing, coating the wax are improved; a primary edge milling and emulsion circulating system is additionally arranged in the rolling procedure, and formulas of emulsion, washing liquid and wax liquid are optimized. The surface quality of finished products is improved, the effect is remarkable, energy and consumption are saved and the production cost is reduced. The method relates to the field of machining of metal copper.

Description

technical field [0001] The invention relates to the field of metal copper processing, in particular to a method for improving the surface quality of an 8mm-diameter low-oxygen bright copper rod. Background technique [0002] The surface quality of the 8mm diameter hypoxic bright copper rod directly affects the market sales. At present, the surface quality of the copper rods produced by many manufacturers on the same production line is uneven and very unstable. The copper powder content of many copper rods is basically 7-18mg / 300mm after 10 rotations of forward rotation and 10 rotations of reverse rotation. The thickness of the oxide layer of the copper rod is basically kept between 300?-1000?. In summer, the finished product will be oxidized and blackened after being placed in the warehouse for about 25 days. In severe cases, multiple black spots will appear and the color will change severely. After 10 revolutions, the copper rod will have obvious peeling phenomenon, the nu...
