Product Introduction
Heavy rails cooperate with track components such as sleepers and ballast to form a mechanical balance system. Through the connection with the sleepers, the load is evenly distributed to the ballast and roadbed, and together with other components, it resists various external forces to maintain the stability and integrity of the track structure.
60kg/m high-speed railway GB heavy rails are a type of rail commonly used in high-speed railway track construction. They have high hardness to ensure the wear resistance and fatigue resistance of the rails. They have good impact toughness and can withstand the impact load when the train is running at high speed to ensure the safety and stability of the track. Some 60kg/m high-speed railway heavy rails need to be heat treated online or offline, such as quenching and tempering, to refine the grains, improve the strength, hardness and toughness of the rails, and improve the wear resistance and fatigue resistance.
Product Specifications
Product Application
Each GB 75kg/m heavy rail produced by GNEE RAIL undergoes multiple rigorous quality inspection processes before leaving the factory. First, advanced ultrasonic flaw detection equipment is used to conduct a comprehensive scan of the interior of the heavy rail to detect defects such as cracks and pores to ensure reliable internal quality. The chemical composition and mechanical properties of the heavy rail are also sampled and tested to ensure that all indicators meet GB standards and special requirements of customers. For example, in the mechanical property test, the yield strength of the heavy rail is required to be no less than 500MPa, the tensile strength is above 900MPa, and the elongation after fracture is no less than 10%, so as to ensure that the heavy rail can withstand huge pressure and impact loads in actual use.
