The model of 22kg light steel rail is usually expressed as "22kg/m", which means that the weight of each meter of rail is 22 kilograms. 22kg rail is widely used in the field of railway transportation, including national trunk railways, local railways, urban rail transit, etc. It has strong carrying capacity and stable operation, and is an indispensable and important part of railway construction.

22kg rail has the characteristics of high strength, high wear resistance, and good fatigue resistance. At the same time, its geometric dimensions are precise, which ensures the stability and safety of train operation. In addition, the specially treated rail also has good corrosion resistance, which prolongs its service life.

1.How to perform daily maintenance of rails? ​

Daily maintenance includes regular inspection of the appearance of rails to check for cracks, wear, deformation, etc.; measuring dimensional parameters such as gauge and levelness to ensure that the track geometry meets the standards; cleaning debris, dust and oil on the surface of rails; inspecting and tightening the rail connection parts to prevent loosening; regularly oiling the rails to reduce friction and wear, and at the same time play a role in rust prevention. ​

2.What should be paid attention to when using rails in low temperature environments? ​

In low temperature environments, the brittleness of rails increases and they are prone to breakage. Therefore, it is necessary to select rail materials suitable for low temperature environments, such as alloy steel rails with good low temperature toughness.

3.What role does the elasticity of rails play in railway operation? ​

The rails have a certain elasticity, which can buffer the impact of wheels on rails when trains pass, reduce vibration and noise during train operation, and improve passenger comfort. At the same time, elasticity can also enable rails to better adapt to the slight deformation of the line foundation and extend the service life of rails and line foundations.
