METHOD FOR INCREASING THE DURABILITY OF RAIL WAYS AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for increasing the wear resistance of rail tracks, comprising increasing the hardness of the contact rails by surface layer of the rail head electric-heat treatment by passing electric current through the contact members, is pressed against the surface to be treated under pressure, followed by cooling the heated zone, characterized in that during operation of track control is performed wear contact rails most wear layer portions tract, the heat treatment is carried out periodically, d stizheniyu critical wear of the rail surface layer having a martensitic structure is 1.5 ... 2.0 mm, directly on the tracks without dismantling the rails, by the mobile device is treated with a working side of the rail head surface at the curved sections of railway track, wherein the heat treatment is carried out before the working correction grinding the rail head surface and heat treatment is carried out by electric-heating to tempering temperature of 850 ° C and cooled with water at a temperature from nent 18-20 ° C.2. A method according to claim 1, characterized in that the critical martensitic wear layer is determined statistically tonnazhu.3 skipped. A method according to claim 1, characterized in that the critical martensitic wear layer is determined by the metrological kontrolya.4. A device for surface working electric-heat treatment of the rail head surface that includes contact heating elements, pressure elements and apparatus for cooling, characterized in that the device is of mounted track machine
