Product Introduction
GB heavy rails are used for laying railways. They must withstand pressure, impact loads, and friction during train operation, and require sufficient strength and a certain degree of toughness. The quality requirements are strict. In addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop hammer testing, and acid leaching of low-rate structur.
GB heavy rails use specific steel grades, such as U71Mn U75V, etc. These steels have high strength, toughness, and wear resistance. By precisely controlling the chemical composition of molten steel, the inherent quality of the steel is guaranteed, enabling it to withstand the huge load of the train without deformation or damage, providing a basic guarantee for the stability of the track.
GB has very strict requirements on the dimensional accuracy of heavy rails. The allowable deviations of dimensions such as rail height, bottom width, and head width are all controlled within a very small range, such as the allowable deviation of rail height is ±0.5mm, and the allowable deviation of bottom width is ±0.5mm, etc. This ensures that the rails can maintain good smoothness and consistency after laying, reduces track unevenness caused by dimensional deviations, and thus improves the stability of train operation.
