摘　　要：介绍并分析比较电镀法、浸涂上引法以及连续挤压包覆法等几种铜包钢线生产方法。电镀法设备体积小 ,投资少 ,但只能生产薄镀层细线 ,并存在环境污染 ;浸涂上引法的产品界面结合强度高 ,长度不限 ,但工艺复杂 ,设备庞大 ,技术难度较大 ,生产效率较低 ;连续挤压包覆技术设备投资少 ,生产率高 ,铜包覆层厚度均匀、无露点、无焊缝 ,内在质量好 ,导电率高 ,成本低 。The methods of copper clad steel contact wire production are compared Less investment and small equipment scale are the advantages of electroplating process, but only thin coating layer filament can be produced, and there is the environment pollution problem The interfacial combination strength of hot copper plating product is high and there is no limitation to the wire length, but the big equipment scale, technical difficulties, and low productivity are the disadvantages of the hot copper plating technology. The continuously extruding and cladding is a ideal technology, it has the advantages of the low investment and cost, high production efficiency and product quality
