Steel rail, we also called rails, tracks, is an important element of the rail system. The steel rail is used with rail joint and railway fasteners like rail clip, railraod tie plate, turnouts to make the train run fast and steady without steering.
As for the rail track sizes, there are some differences among countries. The common standards in Europe are 40kg/m, 50kg/m, and 60kg/m. And the common rails standards in China are 43kg, 50kg, 60kg, and 75kg. Generally, the most common rails standards are 50kg, 60kg/m and 75kg/m. The United States prefers to the heavier rails. For example, the coal line applied to the 75kg/m rails at the United States. Where can buy railroad rail? If you want to find the heavy/light railroad track and crane rail manufacturers, you can choose the GNEE RAILWAY RAILWAYL.

Steel Rail processing
The process of steel rail manufacturing is simple. The most important is rolling the steel. After choosing the suitable steel billet, then the next step is rolling the steel.
Disposing the billet steel
Adopt the continuous casting bloom to improve the macrostructure of the billet steel. Besides, adopt the vacuum degassing and secondary refining technology to ensure the inner quality of the billet steel. This technology can control the Residual element and gas content and ensure the purity of the steel.
Rolling
As we know, the steel billet through rolling, cooling, and straightening can be made to the rails. During the process, the vital part is rolling. There are two methods to rolling: groove rolling and universal rolling.
Heating
Heating is better for improving the mechanical property drastically. The most popular heating technology is Quenching and tempering heat treatment and slow quenching.
Straightening
We would like to adopt the long rod to rolling, cooling and straightening. This technology is better for increasing the yield, reducing the residue stress and lengthening the service life of the steel rail.
Inspecting
Through the online quality inspect center, adopt the ultrasound wave, eddy, and laser to inspect the steel inner quality, the rail surface quality and the railroad track dimension.
Cutting
It is common that adopt the carbide machine to drill and process the rail head so that can get the high accuracy.
Except for the advanced production technology, GNEE RAILWAY RAILWAYL provides various standards railroad tracks and many different railroad track dimensions. As a railway component manufacturer, we also provide customization service for joint bar, rail clip, railroad spike, etc.
