高速列车用铜合金接触线用材料及其加工工艺

在研究和分析国内外高速列车用铜合金接触线的基础上，结合目前铜合金接触线的生产现状，对我国铜合金接触线材料和加工工艺进行了分析。随着电气化铁路运行向高速化发展，开发新型的Cu—Cr-Zr系、Cu—Mg系铜合金接触线是必要且可行的。目前我国铜合金接触导线制造技术比较落后，在铜熔体洁净化处理和连铸成形两个关键工序上，缺乏有效手段，大大影响了产品的最终性能。综合考虑产品的最终性能和大规模连续化生产的要求，在加工工艺方面，连铸连轧法和连续挤压法是未来开发的重点。

Materials and Process Technics of Copper Contact Wires for High-Speed Train

Based on systematical research and analysis on domestic and foreign high speed train contact wire, and combining current production status of the copper alloy contact wire, the contact wire materials and processing technics were analyzed. Along with high-speed developing of the electric train, the development of Cu-Cr-Zr and Cu-Mg copper alloys is necessary and feasible. At present, the manufacture technology of copper alloy contact wires is backward. It is short of effective means in purifying copper melt and continuous casting forming. This affects the final properties of product seriously. In order to meet the final properties of product and massive continuous production, continuous casting and rolling forming are of important in and continuous extrusion the sight of technics.
