钢轨全长淬火是近几年发展起来的一项热处理新工艺,它不仅可以显著地提高钢轨的耐磨性,延长钢轨使用寿命,大大节约钢材,而且也是减少养护维修工作量,确保铁路安全行车的一个极为有效的措施,具有较好的技术经济效果。上海铁路局科研所工务处、铁道部科学研究院金化所和建厂局科研所等单位共同协作,改进了所使用的工艺装备、工艺参数和冷却 Full-length rail quenching is a new heat treatment technology developed in recent years. It not only can significantly improve the wear resistance of rails, prolong the service life of rails, save the steel greatly, but also reduce the maintenance workload and ensure the safe driving of the railway A very effective measure, with good technical and economic results. Shanghai Railway Bureau Scientific Research Office of the Ministry of Railways, Jinhua Institute of Science and Construction and Construction Institute of Science and other units work together to improve the use of process equipment, process parameters and cooling
