Hot Sale Steel Quality Rail Railway Track in Bulk Used Rail
Development History
Quality control is crucial throughout the production process. The first is the selection of raw materials, which must ensure that the quality of steel meets national standards and is strictly tested. The second is the temperature control in the heating process, and the temperature parameters must be accurately mastered to ensure that the steel has good plasticity and toughness.
In the rolling process, it is necessary to strictly control the pressure and speed to ensure uniform deformation of the steel. Processes such as cooling, grinding and cutting also need to be carried out in strict accordance with standards to ensure the dimensional accuracy and surface quality of the rail.
Specifications
In addition to the control in the production process, the quality of the rail also needs to undergo strict testing. The commonly used detection methods include ultrasonic inspection, magnetic particle inspection, hardness testing and so on. These detection methods can effectively detect the surface and internal defects of the rail to ensure its safety and reliability.
Our company supplies the following series of rails
Composite rail is mainly used for railway lines under special conditions, such as high altitude areas, coastal areas and so on. It has the advantage of a variety of materials and can meet the needs of use under special conditions.

In order to best match the stiffness and stability, countries usually control the ratio of the rail height to the bottom width, is H/B, when designing the rail section. Generally, H/B is controlled between 1.15 and 1.248. The H/B values of rails in some countries are shown in the table.
As an important part of railway transportation, the quality of rail is directly related to the safety and efficiency of railway transportation. Therefore, it is essential to strictly control the quality during the production process to ensure that the rail meets national standards.
