New Rail Grinding. New rail. During the grinding of new rails, which should be performed before putting the rails into service or as soon as possible thereafter, the differences in the surface structure (low-carbon and high-carbon areas) caused by milling in the rail production process are eliminated by removing the upper surface-decarburized layer. As well as creating a homogeneous surface of

Application of grinding to reduce rail side wear in

Abnormal rail wear always results from bad wheel/rail contact geometry, so rail grinding is used to reduce rail wear, with most grinding work focused on curved track. In straight track, most rail wear is located at the TOR, and the wear rate is much less than that in curved track.

Study on wear characteristics of brazed diamond

15.04.2019· When the rail grinding wagon grinding power is reduced and the grinding bandwidth is increased, the grinding pressure experienced by the brazing sheet is reduced. In this paper, the wear of brazing sheet under different pressures of 80 N-230 N is studied. The test pressures and other conditions are shown in Table 3.

Controlling rail wear. Profile grinding is also used to improve the steering of conventional three-piece freight bogies, and thus reduce gauge face wear5. This application - initially introduced by the heavy-haul mining railways in Western Australia during the late 1970s - resulted in the development of a set of asymmetric rail head profiles.

Vehicle, Track and Wheel: Safety and Efficiency at

Preventive rail grinding has dramatically affected the way railroads manage wear and rail life. The "magic wear rate," coined by Kalousek, is the guiding principle for that type of grinding. The magic wear rate is the rate of wear at which any rolling contact fatigue (RCF) cracks in the initial stages of development are removed, either by wear or through preventive grinding. "The lower
