The rail bending and forming technology is widely used in railway construction and operation and maintenance because it can give rails precise curve shapes, and it plays a unique role in different scenarios.
Urban rail transit is its high-frequency application field. Subway and light rail lines often need to achieve small radius turns in a narrow space. The cold bending process, with its high precision advantage, can control the bending error of the rails to a very small range, ensuring the smooth operation of trains in and out of stations and switch areas. At the same time, the bent rails can better fit the complex underground terrain of the city, reduce the spatial conflict between the tracks and surrounding buildings, and improve the flexibility of line planning.
In the construction of mountain railways and complex terrain lines, the advantages of hot bending technology are significant. In the face of large slopes and large radius curves, the hot bending process can handle rails with higher hardness to adapt to rugged terrain. For example, in railway projects that cross mountains, the rails shaped by the hot bending process can fit the trend of the mountain closely, reduce the difficulty of bridge, tunnel and other engineering construction, and ensure the safe connection of the line.
Heavy-duty railways also rely on rail bending and forming technology. Due to the large impact of heavy-loaded trains on the track, it is necessary to optimize the curve transition by accurately bending the rails to reduce abnormal wear of wheels and rails. Cold-bent or hot-bent rails combined with stress relief treatment can effectively improve the track's bearing capacity, extend its service life, and ensure safe and efficient cargo transportation.
In addition, in railway hubs and turnout areas, rail bending and forming processes are used to manufacture special-shaped point rails, heart rails and other components to achieve train steering and track change functions. By precisely controlling the bending angle and curvature, the track connection in the turnout area is ensured to be smooth, reducing vibration and noise when the train passes. Rail bending and forming processes have become the core technical support to meet the needs of diversified railway construction.Founded in 2008,GNEE RAIL has been deeply involved in the rail field for many years and has a professional foreign trade team that can provide you with the best products and services.
