Detailed explanation of 43 rail parameters
43kg steel rail, also known as 43kg/m rail, is one of the heavy rails commonly used in my country's railways. Its basic parameters include key dimensions such as rail height, bottom width, and head width. These parameters not only determine the load-bearing capacity and service life of the rail, but also have an important impact on the running stability and safety of the train.
* Rail height: refers to the vertical distance from the top to the bottom of the rail. The standard height of the 43 rail is 140mm, which ensures sufficient strength and stability to withstand the heavy pressure of the train during operation.
* Bottom width: that is, the width of the bottom of the rail. For the 43 rail, the bottom width is usually 114mm. This width helps to disperse the pressure of the wheel on the rail and increase the service life.
* Head width: refers to the width of the top of the rail, and its standard value is usually 70mm. Appropriate head width can ensure stable contact between the wheel and the rail and reduce the risk of derailment.
The rail bottom thickness is an important parameter of 43 rails, which is directly related to the bearing capacity and service life of the rails. The standard rail bottom thickness of 43 rails is 15.5mm. This thickness ensures that the rails will not deform when under heavy pressure, affecting the stability and safety of train operation.
The setting of the rail bottom thickness is carefully calculated, ensuring sufficient strength while considering material savings and manufacturing costs. Too thin rail bottom may cause the rail to wear or deform rapidly during use, while too thick rail bottom may increase unnecessary material waste and cost.
