Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rails, specifically to a fixed steel rail wear reduction device. Background Technology
[0002] Fixed rails refer to rails that are fixed to tracks in a specific way, typically used in railway track laying. The main function of fixed rails is to support and guide train movement, bearing the weight of the train and the impact forces during travel, ensuring the train's smoothness and safety. Fixed rail wear reduction refers to the techniques and methods used to reduce rail wear through a series of fixing measures. These measures mainly include optimizing track design, using wear-resistant materials, improving track smoothness, regular grinding, and enhanced maintenance. However, most of these measures reduce rail wear by using wear-resistant materials, improving track smoothness, regular grinding, and enhanced maintenance, with fewer structural wear-reducing devices.
