Product Introduction & Application
According to the current GB standard, heavy rails have evolved from the original 38, 43, 45, 50 and 60kg/m to the current 43, 50, 60 and 75kg/m. Among them, the usage rate of 60kg/m can account for more than 90% of the newly built lines, and 75kg/m is used in heavy-load lines. The most commonly used material is U71Mn. The high carbon content greatly improves the mechanical properties of the rails, such as strength and hardness.
Hot rolling technology is often used in the production process. In addition, online heat treatment technology is also common to improve the wear resistance, toughness and fatigue resistance of heavy rails and extend the service life of rails.
