Product Introduction
GB heavy rails are heavy rails produced according to national standards. Common materials are U71Mn and U75V. They are divided into core specifications such as 38kg/m, 60kg/m, and 75kg/m according to weight per meter. There are significant differences in performance and application among the specifications.
For example, the 75kg/m heavy rail is designed for heavy-duty railways. It is mainly made of U75V steel, with a rail height of 192mm, a bottom width of 164mm, and a tensile strength of over 950MPa. It can withstand repeated rolling by heavy-duty trains with an axle weight of more than 30 tons and an annual transportation volume of over 100 million tons.
GB 38KG heavy rail is a hot-rolled rail with a theoretical weight of about 38 kilograms per meter, which belongs to heavy rail.
Main features:
Sectional dimensions: rail height 134mm, bottom width 114mm, head width 68mm, waist thickness 13mm. This section design provides a certain structural basis for improving toughness on the basis of ensuring a certain bearing capacity, which can evenly distribute the force and reduce the adverse effects of stress concentration on toughness.
Production and quality control: GNEE RAIL has strict quality requirements in the production process of 38KG heavy rails. In addition to testing the chemical composition and mechanical properties, it strictly controls the factors that affect toughness, such as internal inclusions, pores and other defects. It needs to undergo drop hammer tests and other tests to ensure that its toughness and overall quality meet the high toughness requirements.
Support and maintenance: It needs to be used with appropriate fishplates, bolts, fasteners and other accessories. During use, due to its high toughness, it may have different wear performance compared to ordinary heavy rails, and it is still necessary to regularly check the rail surface wear, cracks, etc. However, due to its good toughness, the probability of serious problems such as sudden fractures is relatively low. The maintenance cycle and method can be reasonably adjusted according to actual usage.
Product Specifications
Product Application
38kg/m heavy rails are suitable for occasions with high requirements for rail toughness, such as sections with high train speeds or frequent braking in some railway branches, as well as railway lines within some industrial enterprises. When there are large equipment running or transporting heavy objects and the impact on the track is large, high-toughness 38KG heavy rails can better adapt, reduce the occurrence of faults such as rail breakage, and extend service life.
