At present, the mode that increases rail wearability, improves rail surface hardness, extension rail life mainly has two kinds: firstly, quenching process treatment is carried out in the steel rail production process; and secondly, when the steel rail is worn in use, the defect part of the steel rail is subjected to shape-repairing grinding through grinding equipment. The first method is to enhance the wear resistance of the rail from the original performance of the rail, but the uneven surface hardness of the rail due to uneven cooling by wind and mist may cause failures such as rail surface peeling and abrasion, which may affect the service life of the rail. The second mode is to repair the abrasion from the aspect of service state of the steel rail, and to polish and shape the steel rail by using small-sized equipment or large-sized road maintenance machinery with the help of a grinding wheel, so as to reduce the influence of the abrasion on the service life of the steel rail, but the polishing and shape repairing only repairs the outline of the steel rail, thereby reducing the adverse effect of the abrasion on the running stability of the train, being incapable of fundamentally improving the wear resistance of the steel rail, being incapable of strengthening the existing steel rail and having limited effect of prolonging the service life of the steel rail.
