Since the rails are always exposed to the air and have been exposed to wind and rain for many years, rust will inevitably occur. This rail is not all iron, the rail is made of high manganese steel. In the upper part of the rail, the layer that is in contact with the wheels, another metal, indium, is added. The addition of indium makes the upper part of the rail have some toughness while ensuring the hardness, which is very important for the wheels of the train.

 

The train track has to bear a very huge weight and friction during the running of the train. In order to ensure the safe operation of the train, the staff will often maintain the rails, so it will not rust seriously.

 

When the rail is rusted, the laser cleaning machine can remove the rust very well. Laser rust removal technology uses high-frequency high-energy laser pulses to irradiate the surface of metal materials, so that the rail absorbs the focused laser energy, and then evaporates or peels off the rust spots on the surface. The laser cleaning machine can effectively remove the rust and oxides on the surface of the rail at high speed, and the laser pulse with a short action time will not damage the metal substrate under the appropriate parameters.

 

Laser cleaning rust removal is very different from the traditional cleaning process, and is more and more popular because of its energy saving and environmental protection. Laser cleaning machines have very important application prospects in the rail transit industry.

 

The laser cleaning machine is suitable for the operator to work alone, with low cleaning cost, environmental protection, high efficiency, good cleaning quality and no damage to the rail substrate. These advantages are irreplaceable by the existing cleaning methods. The laser descaling machine will gradually replace the traditional cleaning methods and become the mainstream equipment for industrial cleaning.
