武钢于1969年结合我国富有资源,试制成功并生产了高硅含铜低合金钢轨钢。轨型采用我国自己设计的每米重为45公斤的新型断面。这种钢轨不仅强度大(б_b≥92公斤/毫米~2),硬度高(轨头踏面基体硬度≥280HB),可不淬火使用,而且冲击韧性和塑性良好。同时,还具有一定的耐大气腐蚀性能。铺设使用表明:钢轨耐磨耐压耐冲击,接头良好,震动小,线路稳定,列车通过平稳,轨腰轨底腐蚀较轻,是一个优良的钢轨钢品种。自1969年以来已生产44.6万吨。
WISCO in 1969 combined with our rich resources, trial success and the production of high-silicon copper-bearing low-alloy steel rail. The railroad track adopts the new section of 45 kilograms per meter designed by our country. This rail is not only strong (б_b ≥ 92 kg / mm ~ 2), high hardness (rail head tread surface hardness ≥ 280HB), can not quench the use, and good impact toughness and plasticity. At the same time, it also has some resistance to atmospheric corrosion. Laying the use of that: rail wear resistance pressure impact resistance, good joints, vibration, line stability, the train through the smooth, rail waist rail corrosion is light, is an excellent rail varieties. 446,000 tons have been produced since 1969.
