钢轨是重要的铁路交通用金属材料之一,直接涉及铁路安全性、舒适性。为了满足我国铁路快速以及高质量发展需要,国内主要的钢轨生产企业相继完成现代化的产线建设以及技术升级改造,不仅从量上保证了自给,从轨型、单重到材质均发生了巨大的变化,以适应不同运行条件对钢轨的不同需求。一、钢轨产能与产量分析2015年,我国重轨产量359.7万吨,同比下降11.3%。当前,国内重轨生产企业主要有四家,分别
Rail is one of the important metal materials for railway traffic, which is directly related to railway safety and comfort. In order to meet the rapid and high-quality development needs of our country’s railways, the major rail manufacturing enterprises in China have successively completed the modernization of their production lines and upgraded their technologies. This not only ensures self-sufficiency in terms of quantity but also huge Changes to adapt to different operating conditions of the different needs of the rail. First, rail capacity and yield analysis In 2015, China’s heavy rail output 3.597 million tons, down 11.3%. At present, there are mainly four domestic heavy rail manufacturing enterprises, respectively
