60kg/m GB Mining Railway Rails Industry

GB heavy rail is a type of rail developed under the national standard framework for high-load and high-frequency operation requirements in railway transportation systems. Its mechanical performance indicators (such as tensile strength Greater than or equal to 880MPa, elongation after fracture Greater than or equal to 9%) have been verified through strict physical and chemical testing. The surface quality must meet the requirements of no cracks, scars, folds and other defects, and can maintain stable geometry and mechanical properties under complex climatic conditions (such as temperature changes, rain and snow erosion).

60kg/m GB mining railway rails strictly follow the GB/T 2585 standard, with a theoretical weight of 60.64kg/m, belonging to the category of heavy rails. In terms of material, carbon killed steel such as U71Mn is mostly used, which is smelted and hot-rolled in open-hearth or oxygen converter. Some of them also need to go through heat treatment processes such as quenching and tempering to make their yield strength Greater than or equal to 880MPa and tensile strength Greater than or equal to 980MPa, with both high strength and wear resistance. During the production process, GNEE RAIL strictly controls the chemical composition and purity in the smelting stage, accurately controls the temperature and reduction amount during rolling to ensure dimensional accuracy, and then uses ultrasonic, magnetic powder and other non-destructive testing technologies to inspect the appearance defects and internal quality of the finished products to ensure that each rail can meet the harsh working conditions of high load, strong impact and high wear of mine railways, providing a stable and reliable track foundation for ore transportation.

As a company specializing in the international trade of heavy rails, GNEE RAIL provides customers with one-stop procurement services with its strong supply chain advantages and rich industry experience. The company's products are widely used in railway construction, industrial and mining transportation, urban rail transit and other fields, and are exported to Southeast Asia, the Middle East, Africa, South America and other regions. GNEE RAIL focuses on technological innovation and product upgrades, and continuously optimizes production processes to ensure that each batch of products meets international quality standards. The company is based on integrity and is committed to establishing long-term and stable cooperative relationships with global customers to jointly open up a broader market.
