CRTS Ⅱ型轨道板模具制作难点与控制办法

The manufacturing difficulties and resolution methods of CRTS Ⅱ track slab molds

CRTS Ⅱ型轨道板是目前中国新建高速铁路最常用的无砟轨道板,制作该轨道板的专用模具是高速铁路建设的关键设备。为保证CRTS Ⅱ型轨道板在磨削时有合理的加工余量,并且磨削后能满足时速350公里的技术要求,在制作CRTS Ⅱ型轨道板模具时需要对各个要点进行控制。

The track slab of CRTS II is one of most common Ballastless track, which is used in high-speed railway construction project of China. The manufacturing molds of CRTS II track slab is key equipment for high-speed railway construction. In order to ensure reasonable process allowance when grinding and meet the requirements of speed at 350km/h after grinding, manufactures should think highly of every key process when produce molds of CRTS II track slab.
