On October 10, the new 60N specifications of the 60N specifications U71MNG 100-meter high-speed rails were made by Hebang Hangang Company to deliver to customers. After testing, the surface quality, size, and physical and chemical performance meet the TB/T2344.1-2020 standard requirements. The batch of products will be used for the Guangzhou-Zhanhan high-speed railway project, with a design speed of 350 kilometers per hour. Through this cooperation, Handan Iron and Steel will exclusively supply the 72,000-ton 100-meter high-speed heavy rail required for the railway project.

Handan Iron and Steel insists on centering everything on efficiency, continues to optimize the structure of heavy rail products, takes advantage of the "integration" of production, marketing, and research, continuously deepens exchanges and docking with China Railway Corporation, actively tracks and participates in the construction of vital domestic and foreign railway projects, and further enhances the 100-meter high-speed Increase sales of high-efficiency products such as heavy rail and increase efficiency. The heavy rail technical marketing team of Handan Iron and Steel Co., Ltd. has strengthened technical docking with the project party and the rail welding factory. Under the strict requirements of high dimensional accuracy, high straightness, and high surface quality of 100-meter high-speed heavy rail, it has optimized and formulated production organization, process control, and Product shipping plan. During the production, technicians implemented head-to-tail stepped temperature difference control during the billet heating stage to eliminate the impact of temperature difference on full-length dimensional uniformity and improve dimensional accuracy. They also adopted new oil film lubrication rolling technology to optimize the all-purpose rolling process and the straightening process. I improve rolling stability and ensure high product quality.

The Guangzhou-Zhanhan high-speed rail line is the high-speed rail project with the largest investment volume and the longest construction mileage in Guangdong Province in recent years. It is also a vital part of China's high-speed rail network. After the railway project is completed and opened to traffic, it will fill the gap in the coastal areas of western Guangdong where there is no ballastless track high-speed railway, and play a crucial role in promoting the social and economic development of western Guangdong.
