通过对鞍钢、包钢、攀钢钢轨性能和质量检验结果的分析，研究了国产钢轨化学成分、力学性能、金相组织、非金属夹杂物、低倍组织、轨端淬火等性能指标的现状及其特点，结果表明，国产钢轨的钢质纯净度有了较大幅度的提高，但个别检验样本的轨端淬火质量不稳定、表面质量和尺度精度超标。 Based on the analysis of rail performance and quality inspection results of Ansteel, Baotou and Panzhihua Iron and Steel, the status quo of the chemical composition, mechanical properties, metallographic structure, non-metallic inclusions, low magnification, rail end quenching and other performance indicators The results show that the steel purity of domestic rail has been greatly improved, but the quality of rail surface quenching of individual test samples is not stable, and the surface quality and standard accuracy are beyond the standard.
