U71mn Steel Rail QU70

U71mn Steel Rail QU70

Steel rails are the main components of railway tracks. Their main function is to guide the operation of locomotives and vehicles, withstand the huge pressure of wheels, and provide a continuous, smooth and least-resistance rolling surface for the wheels.

Products Description

 

Railway rails usually have an "I"-shaped cross-section, consisting of three parts: rail head, rail waist and rail bottom. The rail head bears the direct pressure of the train wheels and needs to have excellent compressive strength and wear resistance; the rail waist mainly plays a role in connection and force transmission, and is the central axis of the overall force of the rail; the rail bottom is connected to the sleeper through a fastener system to disperse the train load and maintain the stability of the track.

 

The rails are subjected to alternating loads for a long time during use, especially under high-frequency and high-speed train operation conditions, and need to have strong fatigue resistance. The rationality of the rail structure and the performance of the material are directly related to whether it can maintain a stable shape for a long time and avoid safety hazards such as breakage and deformation. Therefore, when designing the rail section, it is necessary to take into account the comprehensive balance of strength, durability and manufacturing cost.
