摘要: 通过对核伤突出路段钢轨伤损特点和伤损原因的研究,以及在成昆线、陇海线的钢轨核伤突出路段进行U75V、U76CrRe热轧钢轨和U75V、PG4热处理钢轨的铺设使用试验,提出了核伤突出路段的钢轨合理选用建议。结果表明,热处理钢轨具有较好的抗疲劳核伤伤损性能,在钢轨核伤突出路段不宜使用热轧钢轨,而应该使用热处理钢轨。

Abstract: The rail damage characteristic and cause have been researched regarding the rail line with notable damage of nucleus flaw. Paving trial of the hot- rolled U76 CrRe and U75 V rail,and the heat treated U75 V and PG4 rail have been carried out in the section with notable damage of nucleus flaw in Cheng Kun line and Long Hai line. The results from research and trial indicates that the heat treated rails have better fatigue and nucleus flaw resistance than hot rolled rails. For the application in the line with notable damage of nucleus flaw,the heat treated rail has been suggested that rather than the hot- rolled rail.
