Corrosion-resistant steel rail for humid environment and production method thereof
The invention belongs to the technical field of production of steel rails for railways, and particularly relates to a corrosion-resistant steel rail for a humid environment and a production method thereof. In order to solve the problems that the corrosion resistance of an existing steel rail for the railways cannot meet the operation requirement in the humid environment for a long time, and the corrosion resistance of the steel rail needs to be improved, the corrosion-resistant steel rail for the humid environment is provided. The corrosion-resistant steel rail comprises, by weight, 0.70%-0.82% of C, 0.1%-0.6% of Si, 0.5%-1.1% of Mn, not greater than 0.030% of P, not greater than 0.025% of S, 0.1%-0.3% of Cr and the balance Fe and inevitable impurities. The invention further provides a preparation method of the steel rail. The corrosion-resistant steel rail is prepared through shot blasting and other operation, a blue oxidation film with the thickness being 0.5-1.5 microns is formed onthe surface of the steel rail, the corrosion resistance of the steel rail can be effectively improved, and the corrosion-resistant steel rail is suitable for improving the corrosion resistance of thesteel rail in the humid environment.
本发明属于铁路用钢轨生产技术领域，具体涉及一种潮湿环境耐腐蚀性钢轨及其生产方法。针对现有铁路用钢轨的耐腐蚀性能无法满足长期在潮湿环境中的运行要求，需要提高钢轨的耐腐蚀性能的问题，本发明提供了一种潮湿环境耐腐蚀性钢轨，化学成分包括：按重量百分比计，C：0.70～0.82％，Si：0.1～0.6％，Mn：0.5～1.1％，P≤0.030％，S≤0.025％，Cr：0.1～0.3％，余量为Fe和不可避免的杂质。本发明还提供了上述钢轨的制备方法，通过采用喷丸等操作，制备了一种耐腐蚀性钢轨，钢轨表面形成了一层0.5～1.5μm的蓝色氧化膜，能够有效的提高钢轨抗腐蚀能力，适宜用在潮湿环境下提高钢轨的耐腐蚀性。
