大连理工大学完成的“高性能铜合金连铸凝固过程电磁调控技术及应用”项目获得国家技术发明二等奖。高铁系统对接触网导线性能具有极高的要求,既要具有高强度,高导电性,还要能够承载大电流、耐高温、抗氧化和耐腐蚀。研究人员研发的铬锆铜合金接触线的性能优于日本PHC接触导线,不但解决了铬锆铜合金在非真空下连铸的世界难题,建成了世界首条铬锆铜合
Dalian University of Technology completed the “high-performance copper alloy casting solidification process electromagnetic control technology and application of” project won the second prize of national technology invention. The high-speed rail system has extremely high requirements on the performance of the catenary wire, which not only has high strength and high conductivity, but also can carry large current, high temperature, oxidation resistance and corrosion resistance. Researchers developed chromium zirconium-copper alloy contact wire performance better than Japan PHC contact wire, not only solved the chromium-zirconium-copper alloy casting under non-vacuum world problems, built the world’s first chromium zirconium copper-copper alloy
