钢轨制造的传统方法正经历着一场重大的变化。一旦当微裂缝、氢气或由于大的硅铝酸盐夹杂物造成钢的污染(特别对氧气吹炼法制造的钢)等一些主要问题被解决,钢轨的性能就会得到不断的改善,从而大大减少因制造原因造成疲劳、断裂、缺陷而引起的钢轨抽换。无论是欧洲传统型的铁路还是城市运输型的,都要要求钢轨具有更高的硬度,以便能更长久地承受磨耗。人们正在为曲线钢轨寻找一种硬度大于350HB的材料。美国铁路工程协会对传统型的美国铁路逐步提高了钢轨硬度标准,硬度最小值从248HB提高到269HB,然后又提高到285HB,甚至把某些铁路线的钢轨硬度最小值提高到300HB。
The traditional methods of rail manufacturing are undergoing a major change. Once microcracks, hydrogen gas or steel contamination due to large inclusions of aluminosilicate (especially for steel made by oxygen blowing) are resolved, the performance of the rail will be continuously improved, greatly increasing Reduce the fatigue caused by manufacturing, rupture, defects caused by rail replacement. Whether it is the traditional European railway or urban transport type, it is required to have a higher hardness of the rail in order to be able to withstand wear longer. People are looking for a curve rail hardness of more than 350HB material. The American Society of Railway Engineering gradually increased the rail hardness standard for conventional American railways by increasing the minimum hardness from 248HB to 269HB and then up to 285HB and even raising the minimum rail hardness of some railway lines to 300HB.
