Product Introduction
GB heavy rails play an important role in the construction of railway networks with the guarantee of national standards, providing reliable support for the rail system; GB 75KG heavy rails, with their weight advantage of 75 kilograms per meter, show excellent corrosion resistance and fracture resistance in modern railway projects, meeting the needs of high-standard construction.
75KG heavy rails are made of high-strength alloy steel, such as U78CrV, etc. After online heat treatment and other processes, the tensile strength and other mechanical properties of the rails are greatly improved, which can withstand the huge pressure and impact of heavy-load trains and meet the stability requirements of high-speed train operation. By optimizing the chemical composition and heat treatment process, the hardness and wear resistance of the rails are improved, the wear of the rails during train operation is reduced, the service life of the rails is extended, and the maintenance cost is reduced.
Product Specifications
It is mainly used in heavy-load railways and particularly busy sections of railways, such as my country's Daqin Railway and other coal transportation lines. These lines have large transport volumes and heavy train axles. The 75KG steel heavy rails can withstand the long-term operation of heavy-load trains, adapt to the transportation requirements of large axle weights and large transport volumes, and ensure the safety and efficiency of railway transportation.
Steelmaking: Processing raw materials to obtain qualified molten steel.
Continuous casting: Casting molten steel into billets.
Heating: Heating the billets to rolling temperature.
Rolling: Rolling into the shape and size of the rail.
Cooling: Control cooling to obtain good performance.
Straightening: Correcting the bending and deformation of the rail.
Flaw detection: Detecting internal and external defects of the rail.
Sawing: Sawing the rail to the required length.
Inspection: Comprehensively inspecting all indicators of the rail.
Packaging: Bundling and packaging for transportation and storage.
Daily maintenance of 75KG heavy rails:
Appearance inspection: Regularly check the rail surface for wear, cracks, deformation, etc., and promptly detect and deal with surface defects.
Track cleaning: Remove debris, dust, oil stains, etc. from the rail surface and around the sleepers to keep the track clean.
Geometric state detection: Use professional tools to measure the track gauge, level, height and other geometric parameters to ensure that they meet the standard requirements, and adjust them in time if deviations are found.
Fastener inspection and tightening: Check whether the fasteners are loose or damaged, tighten or replace them in time to ensure that the rails and sleepers are firmly connected.
