How is the GB 22kg rail manufactured?
The GB 22kg rail, a Chinese standard light rail (GB/T 11264), is manufactured primarily through hot rolling high-quality carbon steel or low-alloy steel (like Q235 or 55Q) into its specific profile, ensuring good strength, compression, and wear resistance for applications in mining and construction. The process involves precise shaping and often includes post-production customization like cutting, drilling holes, bending for curves, and surface treatments (like anti-rust oil) to meet project needs, followed by rigorous quality checks for safety and performance.
Manufacturing Steps:
- Material Selection: High-quality carbon steel or low-alloy steel (e.g., Q235, 55Q) is chosen for its excellent mechanical properties, including good compression and fatigue resistance.
- Hot Rolling: The steel billet is heated and passed through a series of rollers that progressively shape it into the precise asymmetrical I-beam profile of the 22kg rail.
- Cooling & Straightening: The rolled rail is cooled and then straightened to ensure it meets the strict dimensional tolerances.
- Cutting & Drilling: Rails are cut to required lengths (e.g., 6m, 9m, 12m) and have bolt holes precisely drilled for fishplate connections, often with custom configurations.
- Surface Treatment: Optional treatments like sandblasting, anti-rust oiling, or galvanization are applied for protection and longevity.
- Quality Control: The finished rails undergo strict mechanical property tests and dimensional inspections to confirm they meet GB/T 11264 standards.
- Packaging: Rails are bundled with steel straps, often with protective end caps, for transport.
Applications of 22kg Rail
- Mining & Quarrying Operations：Main haulage tracks in coal and metal mines, built for ore and equipment transport in open-pit environments.
- Railway Infrastructure Support：Used in sidings, maintenance yards, and light locomotive tracks within industrial railway systems.
- Heavy Industry & Port Logistics：Rails for container yards, bulk transfer zones, and high-temp steel mill areas using durable 55Q steel.
- Construction & Engineering Sites：Tracks for heavy machinery in temporary works or permanent lines in industrial parks and logistics hubs.
