12月15日,中国首批60kg/m 时速350公里的100米长尺钢轨在攀钢万能轧机生产线诞生。12月16日,铁道科学研究院专家来到攀钢,对时速350公里高速钢轨进行了检查验收,认为高速轨表面质量、平直度等各项性能指标均符合要求。攀钢首批生产的1500吨60kg/m 时速350公里高速钢轨即将发往西安,铺设在陇海高速铁路线试验段。未来10至15年是我国铁路大建设、大发展时期,
On December 15, the first batch of 100-meter-long rail with a speed of 350 km / h and a speed of 60 kg / m in China was born in the Panzhihua universal mill production line. On December 16, experts from Railway Science Research Institute came to Panzhihua Iron and Steel Co., Ltd. and inspected and accepted the high-speed steel rails at a speed of 350 kilometers per hour. They considered that all the performance indexes such as surface quality and flatness of high-speed rail met the requirements. The first production of Panzhihua Iron and Steel 1500 tons 60kg / m 350 kilometers per hour speed rail will be sent to Xi’an, laying in the Longhai high-speed railway line test section. The next 10 to 15 years is China’s railway construction, large-scale development period,
