Abstract

本发明公开了一种用于高速和准高速铁路的钢轨及其制造方法。通过降低碳含量，并配合轧后控制冷却的方式，得到具有优良的滚动接触疲劳性能的钢轨，所述钢轨包含的化学成分以重量计为：0.40%～0.64%的C，0.10%～1.00%的Si，0.30%～1.50%的Mn，少于等于0.025%的P，少于等于0.025%的S，少于等于0.005%的Al，大于0少于等于0.05%的稀土元素，总量大于0且小于等于0.20%的V、Cr和Ti中的至少一种，以及余量的Fe和不可避免的杂质。根据本发明的方法制造的钢轨保持了现有高速铁路的钢轨的强度和硬度的同时提高了钢轨的韧塑性和屈服强度，并提高了形成在钢轨表层的疲劳微裂纹萌生及扩展所需的能量值，从而在相同条件下可以改善钢轨的滚动接触疲劳性能，最终提高钢轨的使用寿命和运输安全性。
