The rails are subjected to tremendous pressure and friction when the train is running, and long-term use will cause rail wear. Rail wear is mainly caused by the following factors: wear between wheels and rails, train running speed, frequency and quality of train running, etc.
Detection of rail wear is the first step to solve the problem of rail wear. The railway department can use the following methods to detect rail wear: manual detection, machine detection, infrared detection, etc.
Repair methods for rail wear
Rail wear repair methods include grinding and welding.
1. Grinding:
For small amounts of shallow rail wear, grinding can be used for repair. After grinding, the wear area is reduced, and the service life of the rail can be extended.
2. Welding:
For severe rail wear, welding is required for repair. After welding, the wear area can be fully restored, which can extend the service life of the rail.
Replacement methods for worn rails
For rails that are severely worn and cannot be repaired, they need to be replaced. The new rails can restore the stability and safety of the line, but it is necessary to choose the appropriate rail specifications and quality.
Rail wear is a common problem in railway transportation, and corresponding measures need to be taken to solve it. Detection and maintenance of rail wear can extend the service life of the rails and reduce operating costs; replacement of worn rails can restore the stability and safety of the line.
