What Injuries May Occur On The Surface Of Rails After Prolonged Use? Rail Grinding Machine Can Help You To Solve

(1)Unevenness of rail welded joints

As a result of rail welding after welding seam at the top surface of the rail metal strength, hardness differences and joints of the original unevenness caused by excessive additional dynamic load on the track, resulting in abrasion, deformation.

(2) Wavy rail wear (periodic longitudinal deformation)

When the wheel-rail contact, produce adhesion and sliding alternately, back and forth process, in the process of surface friction also appeared in the size of the alternating changes, so that the amount of wear and tear in the process is not the same, wave wear also appeared. Wave abrasion is divided into ripples (wavelength 30-80mm), short-wave waves (wavelength 80-300mm), and long-wave waves (wavelength 300-1000mm) according to the wavelength.

(1) Fish crack

Fish cracks occurring in the early stage is not controlled, there will be away from or fall off the block, and will even develop into a nuclear injury on the transverse surface of the rail head and lead to broken rails.

Disposal after discovery of injury
-The injured rails should be marked at the defects according to the prescribed method after discovery.
-When seriously injured rails are found, and lightly injured rails are found in bridges and tunnels, the line work area (workshop) and the dispatching of the work section should be notified immediately, and the work section should immediately replace or deal with seriously injured rails affecting the safety of travelling, and other seriously injured rails, and lightly injured rails found in bridges and tunnels should be replaced or dealt with within 24 hours.
For the rails which are not under the road with serious injuries and rails with development of minor injuries, they should be monitored, recorded and notified to the line work area.
-Where acetylene gas cutting or burnt rails are found, the line work area should be notified promptly for immediate replacement.
If any problem is found in the inspection of rail flaw detection vehicle, it should immediately notify the railway section to deal with it, and notify the relevant units of the inspection result after the inspection, and the railway section should use the flaw detector to do a good job in reviewing and dealing with the injury and damage information sent out by the large-scale rail flaw detection vehicle.
