Steel rail is an important component used in railway systems, which is the track on which trains travel. Steel rails are usually made of high-quality steel and have characteristics such as high strength, wear resistance, and corrosion resistance. The main function of the steel rail is to carry the weight of the train while providing a stable track for the train to travel. It can disperse the weight of the train, reduce ground pressure, and ensure safe and smooth operation of the train.zmwm19 Steel rails are usually composed of multiple rail sections, each connected by bolts. The length of the track section is generally about 12 meters, and can be spliced and extended according to the needs of the railway line. Steel rails require frequent maintenance and repair during use to ensure their normal operation and safety. Common maintenance tasks include track grinding, track replacement, track fastening, etc.
