摘要

通过对引进上引法无氧铜杆生产线的技术改造

试制了无氧铜接触线

并研究了无氧铜接触线加工工艺及产品性能。结果表明:Fe含量对无氧铜接触线电阻率影响较大

对于85mm2 无氧铜接触线

在w（Fe）超过2 0×1 0 -6时

电阻率超标;S、O、H含量对其强度及电阻率影响不大

但对其塑性影响较大

当w（S）超过3 8×1 0 -6、w（O）超过8×1 0 -6、w（H ）超过0 .6×1 0 -6时

无氧铜接触线塑性显著下降。S含量取决于电解铜原料

Fe、O、H含量取决于上引法连铸的生产工艺过程。

Abstract

The process on characteristics of oxygen-free copper contact wire were studied. The results show that the resistivity of contact wire is effected by Fe evidently and will become unqualified when w（Fe） arrives at 20～30×10 -6 . S、H、O effect the strength and resistivity rarely

nevertheless

effect the Elongation evidently. The situation can be worse when w（S） is up to 38×10 -6

w（O） is up to 8×10 -6 or w（H） is up to 0.6×10 -6 . S content is dependent on the raw material-copper cathode. Fe

H content is dependent on the process.
