Comparative Analysis of the Rail Property ofShenshuo Railway

This paper seeks to have a comparative analysis of component,macrostructure,metallographic phase,microscopic structure and inclusion between the existing steel rail of Shenshuo railway and foreign heavy rail,has done an experimental study about mechanical property of the steel rail,and appraises the combination property of several kinds of steel rail.The results show that the property of all the three kinds of steel rail that are now used on Shenshuo railway meet the corresponding requirements of the standard about property,but the difference occurs in the actual indexes among the three kinds of steel rail.According to the features of heavy haul railway,the usability of U75V in heavy haul railway is better than that of U71Mn.The improvement the property of alloy rail,grain refinement and heat treatment after rolling are the important means.
