Product Introduction & Application
Continuous casting and rolling is an advanced production process, which is widely used in the production of heavy rails. The main production process is to continuously cast molten steel into billets of a certain shape and size, and then directly send it to the rolling mill for rolling without cooling, so as to realize the continuous production of molten steel to finished rails. First, steelmaking is carried out. Raw materials such as molten iron are smelted in a converter or electric furnace to remove impurities and adjust the composition to obtain molten steel that meets the requirements. Then continuous casting is carried out. The continuous casting billet is then directly sent to the heating furnace for heating to reach the appropriate rolling temperature, and then enters the rolling mill for multiple rolling, and the continuous casting billet is gradually rolled into the shape of a 60kg/m heavy rail.
The use of continuous casting and rolling technology can improve the purity of heavy rail steel. Heavy rails are continuously rolled at high temperatures, with uniform deformation, dense structure, and greatly improved mechanical properties such as strength, hardness, and toughness.
In addition, with advanced automated control systems and high-precision rolling equipment, the size and shape tolerances of heavy rails can be accurately controlled, improving the dimensional accuracy and surface quality of the products.
