Description

Technical Field

[0002] With the rapid development of my country's high-speed railways and the continuous improvement of railway transportation capacity, rail contact fatigue damage is becoming increasingly serious. This damage manifests itself in rail surface peeling, corrugated wear, rail head crushing, cracks, and rail breakage, seriously impacting the safety and economic efficiency of railway transportation. If these damages and defects are not promptly addressed and effectively controlled, the rails will continue to deteriorate and fail, resulting in high maintenance costs. Rail grinding, a recognized rail maintenance technology, effectively repairs rail profiles, improves wheel-rail contact, and significantly extends rail service life. Therefore, it has been widely used in rail transportation both domestically and internationally, significantly improving operational economics.
