Product Introduction
As the main load-bearing component of railway tracks, GB heavy rails have unique and scientific design advantages in structure.
▇ The rail head is the key part where the heavy rail directly contacts the wheel. In order to enhance its wear resistance, the rail head adopts a quenching treatment process. Through heating and rapid cooling, the surface hardness of the rail head is significantly improved, which can effectively resist the friction and wear of the wheel. At the same time, the arc shape design of the rail head has been tested and optimized a lot, which can evenly distribute the wheel pressure, reduce local stress concentration, and extend the service life of the rail head.
▇ The rail waist part plays the role of connecting the rail head and the rail bottom. Its reasonable thickness and height design ensure sufficient support strength while having a certain elastic deformation ability. It can effectively buffer the impact force transmitted by the wheel when the train passes and reduce the fatigue damage of the rail.
▇ The rail bottom increases the contact area with the sleeper through a larger bottom width and a suitable slope design, improves the lateral stability of the rail, and prevents the rail from lateral displacement under the train load. In addition, the slope design of the rail bottom is also conducive to drainage, reducing the erosion of rainwater on the rails and sleepers, and further enhancing the durability of the track structure.
50KG heavy steel in railway rails usually refers to rails weighing about 50 kilograms per meter. 50KG heavy rails are made of U71Mn material, which has high strength and good wear resistance. They can withstand the huge pressure and friction during train operation, ensure the stability and service life of the rails, and withstand long-term train loads without severe wear and deformation.
