22kg Q235B 55Q Light Steel Rail Track Used in Railroad Crane Rail for Sale

22 kg rail steel usually means that its mass per meter length is about 22 kg. This type of rail steel is mainly used in light rail and mining rails.

Rails are key materials for railway construction, and their size specifications are directly related to the safety and stability of the railway.

Its standard dimensions are as follows:

* Height: about 107mm;

* Bottom width: about 92mm;

* Head width: about 50.8mm;

* Waist thickness: about 10.7mm.

These dimensions ensure the strength and stability of the rail steel while meeting the lightweight requirements. In practical applications, 22 kg rail steel is often widely used due to its moderate weight and economy.

1.How do rails and sleepers work together? ​

The rails are laid on sleepers, which support the rails and disperse the pressure on the rails to the roadbed. The spacing of sleepers should be reasonably set according to factors such as the type of rails, the axle weight of the train and the running speed, and the general spacing is about 0.5-0.6m. The rails are connected to the sleepers through fasteners, and the fasteners must ensure that the connection between the rails and the sleepers is firm.

2.Is the insulation performance of the rails important? In what cases should it be considered? ​

The insulation performance of the rails is very important in some cases. In the railway lines in the automatic block section, in order to ensure the normal operation of the signal system, the rails need to have good insulation performance to prevent current leakage from interfering with signal transmission.

3.How to balance the hardness and toughness of the rails? ​

By reasonably selecting the rail material and optimizing the production process to balance hardness and toughness. In the steelmaking process, the chemical composition is precisely controlled, such as adjusting the content of elements such as carbon, manganese, and silicon, to obtain a suitable metallographic structure.
