Hot-rolled 15kg rails for mining refer to 15kg rails made by hot rolling process and suitable for mining railway systems. Among them, hot rolling is a common manufacturing method in the production process of rails. It uses heated billets to roll through rolling mills to form the final required rail shape and size. Compared with cold rolling or other manufacturing methods, hot rolling process can effectively improve the strength, toughness and wear resistance of rails. These characteristics are particularly suitable for transportation needs in harsh environments such as mines.
Hot rolling refers to heating the billet to a certain temperature (usually above 1100℃), and then deforming it through a multi-pass rolling process to finally form a rail of the required specifications. Compared with cold-rolled rails, hot-rolled rails have higher strength and better plasticity, so they can better withstand the huge pressure and impact brought about during transportation.
