Product Introduction
As an important standardized product in the railway industry, GB heavy rails are heavy rails produced according to GB standards. Their production process reflects the high-end technical level in the field of metallurgical manufacturing. Starting from steelmaking, the advanced smelting process of "three-in-one" of molten iron pretreatment, converter steelmaking, and refining outside the furnace is adopted to effectively control the impurities and gas content in the steel. The continuous casting process adopts an arc continuous casting machine to produce steel billets with excellent internal quality. The rolling of the rails adopts a universal rolling process, combined with an automatic control system to achieve precise control of the rail size. In order to increase the service life of the heavy rails, the rail heads are strengthened to give them good resistance to plastic deformation and peeling. The finished heavy rails have passed strict quality control, and various performance indicators have reached the international advanced level. They are widely used in domestic and foreign railway engineering construction, providing a solid track foundation for railway transportation.
GB 12m 60kg tunnel heavy rails are generally made of U75V and other materials, which are high carbon steel. This material is hot-rolled and fully quenched, and has high strength, hardness, good wear resistance and fatigue resistance, and can withstand the pressure, impact load and friction of trains running in tunnels.
Product Specifications
Product Application
It is mainly used for laying railway tracks in tunnels and can adapt to the special environment in tunnels, such as relatively narrow space and high humidity. At the same time, 60kg tunnel heavy rails are also widely used in trunk railways, including some busy passenger and freight mixed lines or parts of heavy-load railways, which can meet the heavy-load and high-speed transportation needs of railways.
Product Packaging & Delivery
To improve the impact resistance of the packaging, honeycomb plastic corner guards are installed on the outside of the heavy rails tied with steel belts. This corner guard disperses the impact force through the hollow structure and protects the ends of the rails. The anti-rust coating is applied using electrostatic spraying technology, and the anti-rust oil is evenly covered with every corner of the rail surface using the principle of electrostatic adsorption. The plastic film is then covered in a vacuum packaging method to extract the internal air and reduce the risk of moisture condensation.
GNEE RAILWAY RAILWAY focuses on GB heavy rail foreign trade business with the vision of "promoting global railway transportation modernization". We focus on heavy rail technology innovation and jointly develop intelligent monitoring heavy rails with steel mills. Built-in sensors can monitor track stress, temperature and other data in real time, and realize remote monitoring and fault warning through Internet of Things technology, providing scientific and technological guarantee for the safe operation of railways. At the same time, we have also built a global service network, set up offices and after-sales service centers in key markets, equipped with professional technicians, and provide on-site installation guidance, maintenance and other services. We have a professional customs declaration and inspection team, familiar with the customs clearance procedures of various countries, and can quickly handle the import and export procedures of goods.
