Steel Rail
A steel rail is a hot-rolled, I- or U-shaped steel bar designed to provide a continuous, smooth surface and lateral guidance for train wheels, crane trolleys, and other heavy-load vehicles. They are high-strength, durable components used to bear significant vertical loads and transmit forces to sleepers.
Key Characteristics and Types
- Types: Classified into crane rails, heavy rails (for railways), and light rails (for mining).
- Properties: Key attributes include high wear resistance, fatigue resistance, and good weldability for seamless tracks.
- Standards: Produced under various international standards, including JIS, BS, and European EN standards.
Technical Specifications:
| Parameter | Specification | Technical Significance & Value |
|---|---|---|
| Product Range | Full Spectrum: Light Rails (9-30 kg/m) • Heavy Haul (40-60 kg/m) • Crane Rails (QU70-QU120) • High-Speed Rails (60E1, 60N) | One-stop solution for all railway, industrial, and transit applications. |
| Material Standards | Premium Steel Grades: • U71Mn / U75V: Standard & High-Strength for mainlines • U20Mn / R260 / R350HT: European grades for fatigue resistance • ARE/AREA/ASTM A1: For North American specifications • Hi-Cr Alloy Steel: For extreme wear/corrosion environments |
Material selection optimized for wear life, impact toughness, and weldability per application. |
| Manufacturing Process | Universal Mill Long Rail Process: 1. Continuous casting of refined steel 2. Multi-pass controlled rolling 3. Online Thermo-Mechanical Controlled Processing (TMCP) 4. Head Hardening / Quenched & Tempered (for premium grades) 5. Precise sawing and straightening |
TMCP ensures fine, uniform pearlitic microstructure for superior strength-toughness balance. Head hardening extends service life 2-3x in curves. |
Special Application Solutions
Mining & Tunneling: Offer AS50, AS60, 50kg/m profiles with enhanced wear resistance for tight curves and abrasive environments.
Port & Crane Applications: Supply QU70, QU80, QU100, QU120 crane rails with high yield strength for point-load applications.
Transit & Metro: Provide 49E1, 54E1, 60E1 with strict tolerance control for low-vibration, low-noise urban networks.
Turnouts & Crossings: Manufacture machined rail parts-frogs, crossings, switch blades-from premium bloom steel for complex trackwork.
Quality Assurance & Testing Protocol
- Chemical Analysis: Spectrometer verification of each heat.
- Mechanical Testing: Tensile, hardness, and Charpy impact tests.
- Dimensional Inspection: Laser profiling and manual gauging.
- Non-Destructive Testing (NDT): 100% ultrasonic testing of head, web, and base; eddy current for surface defects.
- Macro/Micro Examination: Etching and microscopic analysis of microstructure.
- Final Audit & Certification: Issuance of comprehensive test reports and material certificates.
