Product Introduction
GB heavy rails are core components of railway tracks produced in accordance with national standards. They are designed and manufactured to meet the stringent requirements of railway transportation for track materials. In terms of raw material selection, high-quality ores with low phosphorus and sulfur are preferred, and steel billets with precise composition are made through modern steelmaking processes. High-precision hole design and rolling control technology are used in the rolling process to make the cross-sectional shape of the rails accurate and the surface quality excellent. In order to improve the service performance of heavy rails, the head of the rail is quenched by residual heat to improve the surface hardness and wear resistance; the waist of the rail is reasonably controlled to reduce the weight while ensuring strength; the bottom of the rail is optimized to enhance the fit and stability with the sleeper. The finished heavy rails must pass strict quality inspections, including chemical composition analysis, mechanical properties testing, non-destructive testing, etc., to ensure that they can operate safely and reliably under heavy load and high speed conditions. They are indispensable key materials for railway construction.
Advantages of 75KG freight heavy rail:
Strong load-bearing capacity: tensile strength ≥ 980MPa, yield strength ≥ 550MPa, can withstand the large axle weight and impact of heavy-load trains.
Super wear-resistant: high hardness, wear resistance improved by 20% - 30%, reducing maintenance costs.
Fatigue resistance: uniform structure, strong crack propagation resistance, can withstand more than 1 billion cyclic loads.
Environmental resistance: corrosion resistance, adaptable to - 40℃ - 60℃ temperature difference environment.
Cost-effective: low cost throughout the life cycle.
Safe and reliable: strict flaw detection, in line with GB standards, good adaptability
