Product Introduction & Application
According to GB standards, heavy rails are often used in scenes such as original line reconstruction, high-speed rail tracks, subway tunnels, and heavy-load lines. Materials such as U71Mn U75V U78CrV are often used. The carbon content and alloy content can improve the wear resistance and strength of the rails.
In order to enhance the wear resistance of heavy rails in the production process, online heat treatment technology is also often used. Online heat treatment is to directly heat treat the rails during the hot rolling production of rails using the residual heat after rolling. By controlling parameters such as heating rate, holding time and cooling rate, the rails can obtain an ideal organizational structure, thereby improving their wear resistance.
