Problems solved by technology

Although this production process can produce rolled copper alloy plates, it still has the following defects: 1. In the smelting process, the smelting furnace continuously stirs the copper alloy metal liquid with the stirring blades in the process of melting raw materials, and the copper alloy metal A large number of air bubbles are generated in the liquid, and the existence of air bubbles causes a large number of air bubbles in the material, which in turn affects the quality of the copper alloy plate processed subsequently, and has the defect of low production accuracy

2. A large amount of oxides are formed on the surface of the semi-finished copper alloy plate produced by the continuous casting process. oxides, thereby reducing the purity of the product and further reducing the quality of the product

3. It is impossible to hot-roll thick semi-finished copper alloy sheets into thin finished copper alloy sheets at one time only through rough rolling and fine rolling processes. Therefore, it is necessary to repeatedly send semi-finished copper alloy sheets to the fine rolling process, which further increases production. process, reducing the production efficiency of the product

4. Each process requires separate equipment, which increases the amount of equipment input, thereby increasing energy consumption. At the same time, the equipment cost is high, and the production cost is increased. In addition, the production process is increased, thereby reducing the cost of the thin copper alloy plate. production efficiency
