Laser Cleaning: And Rail Corrosion Say Bye!

By the end of 2016, China had a total length of 121,000 km of railways operating, ranking second in the world. The mileage of high-speed railways exceeded 19,000 km, ranking the first in the world!

According to the investigation, China's railways mainly use seamless railways with a coverage rate as high as 70%. The key process for seamless rail production is rail welding. The impact of rail cleaning technology on welding is crucial.

Traditional grinding faces many problems

Depth of grinding, to ensure cleanliness, but the destruction of the arc surface of the rail surface, affecting passenger ride comfort.
Reduce the amount of grinding to ensure that the arc shape, but lead to serious corrosion residues, bought a huge security risk.
Consumption of a large number of grinding wheel supplies, expensive, serious environmental pollution, and the workers have a serious health hazard.
Work efficiency is low, cleaning cycle is long, virtually increase manpower costs.

Modern laser cleaning brings the gospel

Cleaning the light source can adapt to the arc surface morphology, to minimize substrate damage.
Laser cleaning allows for selective removal of contaminants, improved cleanliness and substrate protection.
No supplies of green cleaning technology to eliminate dust pollution, significantly reduce cleaning costs.
Cleaning light source can use the flexible transmission of fiber, with the robot integration work to improve work efficiency.

As a new era of high-tech cleaning technology, laser cleaning is very important for solving the problems of high scrap rate, high cost and high environmental pollution caused by current rail cleaning. Moreover, along with the related industries Scientific research and technological progress, but also bring huge economic and social benefits!
