Railway parts processing dimensions and appearance quality
May 28, 2018

Railway component processing is part of the railway line during the production process. To a certain extent, it mainly refers to the track including its rails, sleepers, connecting parts, track beds, anti-climbing equipment, rail supports, and turnouts. As a holistic engineering structure, the track is laid on the roadbed and plays a guiding role in the operation of the train. It directly bears tremendous pressure on the locomotives and their loads.

During the manufacture and use of railway component processing, the rails are primarily produced by rolling oxygen furnace smelting and open-air carbon-killed steel. During use, they can withstand the operating pressure and impact load of locomotives and vehicles.

During the processing of railway components, the rails are generally produced by some domestic steel mills, such as Anshan Iron and Steel and Wuhan Iron and Steel. In addition, due to the large amount, some physical and chemical properties required by China's technical standards are still imported. Rail and rail attachments determined according to foreign standards.

Railway parts processing dimensions

The length and other geometrical dimensions and tolerances of the rails are stipulated by the relevant standards for light and heavy rails in “8”.

The appearance quality of railway component processing

The rolled rails should be straight and must not bend and twist significantly. The local bending and torsion of the light-heavy rails and their corrective deformation amount, the inclination of the rail end surface, etc., shall not exceed the standards.
