How do seamless rails solve thermal stress problems?
In the laying time, according to the laying of long-term local meteorological data, calculate a fit temperature and corresponding stress, during the production of rail, the rail using tensile data properly, the internal rail leaving a stress. In this way, even if the rail is stretched and contracted, it is only offset with the original stress, so as to ensure the expansion of the rail within the controllable range
The fastening of the track of the jointless track adopts a special elastic fastener and an anti climbing device, and the track is pulled by force
Seamless line is not entirely seamless, but this gap is pulled very longOrdinary line every 25 meters, one rail seam, seamless rail with long rail and long rail, almost every 1 kilometers to set a rail seam. This rail joint is used to solve the temperature stress as common rail joints
