武钢利用大冶铁矿含铜的自然资源,在1958～1964年先后试制了八批含铜钢轨,并于1966车下半年起正式试生产。普通碳素含铜钢轨(WP1)的各项性能均满足了技术条件的要求,与不含铜的普通碳素钢轨比较,它具有较好的强度、硬度、韧塑性、低倍组织、落锤挠度、耐磨性和耐疲劳性,同时钢轨含铜还能提高抗缺口敏感性能,在设计成份范围内,铜对钢轨无明显的时效作用。 WP1钢轨钢轧成43公斤/米钢轨,经三年九个月的铺设使用后,与同期铺设的普碳轨比较,耐磨性能提高10.3～25.1％,耐大气腐蚀性能提高21～76％。从1966～1974年,已生产47万吨,用于社会主义建设。
Taking advantage of the copper-bearing natural resources of Daye Iron Mine, WISCO piloted eight batches of copper-containing steel rails from 1958 to 1964 and formally started trial production in the second half of 1966. The performance of common carbon copper-containing rail (WP1) meets the technical requirements. Compared with ordinary carbon rail without copper, it has good strength, hardness, toughness and ductility, low magnification, Deflection, wear resistance and fatigue resistance, while rail copper can also improve anti-notch sensitivity, within the scope of the design components, copper on the rail no significant aging effect. After being laid for three months and nine months, the wear resistance of WP1 rail steel increased from 10.3% to 25.1% and its atmospheric corrosion resistance increased by 21% to 76% compared with the conventional carbon rail laid over the same period. From 1966 to 1974, 470,000 tons have been produced for socialist construction.
