Products Description
The quality of rails is very important for the safety of railway transportation. Rails are of excellent quality and must be maintained regularly to extend their service life. Conventional rail maintenance includes rail surface grinding, ultrasonic flaw detection, replacement of damaged sections, etc. Especially in high-speed railways and heavy-duty railways, rail maintenance is more frequent and technical requirements are stricter.
High-speed railways have much higher quality requirements for rails than ordinary railways. High-speed operation has extremely high standards for the flatness, strength, toughness and stability of rails. To this end, high-speed railway rails use high-grade steel and use welding technology to form long rails or seamless rails to reduce the number of joints and improve running smoothness. At the same time, high-speed tracks are laid with high precision, and the straightness and welding quality of rails need to be strictly controlled to ensure that trains can run safely at 300km/h or even higher speeds.
Product Parameters
Through a scientific maintenance system, fatigue cracks and corrugation can be effectively prevented, the overall line operation efficiency can be improved, and the failure rate can be reduced.
