Product Introduction & Application
U71Mn has a high carbon content, which gives the heavy rail a high strength, and can withstand the huge pressure and impact of locomotives and vehicles, ensuring the safe operation of the railway. Even if it is used for a long time, its good wear resistance can well guarantee the service life of the heavy rail, and it is not easy to have defects such as fatigue cracks, which improves the reliability of the railway line.
After steelmaking and continuous casting, the rails are heated to make them have good plasticity for subsequent rolling processing. The heated ingot is rolled by a universal rolling mill and other equipment. Through multiple rolling passes, the ingot is gradually rolled into the required heavy rail shape and size, and the dimensional accuracy and surface quality of the heavy rail are controlled. The heavy rails after rolling are subjected to finishing processes such as straightening, cooling, sawing, drilling, etc., so that they meet the quality requirements of the finished rails.
