The preparation method comprises: mixing, smelting, covering, deoxidizing, revolving furnace, covering, holding, detecting, casting, sawing, ingotting and heating, hot-rolling, milling surface, coarse rolling,end shearing, intermediate annealing, fine rolling, product annealing, surface passivating, and packaging. This product has high conductivity, strength, extensibility, and welding feature. The tensionprocessing ratio can come up to 99. 99%.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal processing, and in particular relates to a copper strip processing technology for copper-clad aluminum-clad cable wires. Background technique [0002] Cable TV signal transmission, large-capacity communication network signal transmission, control signal cables, light vehicle cables, welding cables, emergency mobile cables, TV excitation coils, ballast coils and deflection coils are all made of pure copper cores Cable. At present, the price of copper materials remains high and is still skyrocketing, resulting in unbearable high costs, causing many manufacturers to look for alternative products, so that low-cost copper-clad aluminum wires emerge as the times require. However, the outer layer of copper must ensure high conductivity, high strength, high elongation and good welding performance. At the same time, it is also required that when the subsequent wire drawing processing rate reaches...
