摘要
供台湾50N型钢轨用于台湾中部的城际准高速铁路上,因此对钢轨的气体含量、夹杂、尺寸精度、平直度等都有较严格要求。文章对50N型钢轨的生产工艺进行了总结,并对钢轨性能进行了研究及评价。结果表明50N型钢轨具有良好的塑性和焊接性能,使用效果较好。
The steel rail of 50N is paved on city quasi - high - speed railway in the middle - line of Taiwan. The content of gas,inclusion,dimensional accuracy and straightness of rail＇steel were strictly controlled. The paper summerizes the process technique of 50N steel rail and studies the rail steel properities. The result shows the ductility is better and it is easy to be welded. The application result is good.
