1) rail welding seam 点击朗读

钢轨焊缝

2) Seamless Welded Rails(SWR) 点击朗读

无缝焊接钢轨

Recently,train is running faster and faster,and considering the stability and security,Seamless Welded Rails(SWR) are used as the train orbits gradually.

近年来,随着火车的提速造成的稳定和安全问题,轨道逐步转为采用无缝焊接钢轨,随着钢轨温度的变化,无缝钢轨可能会因为热胀或冷缩的金属特性并且在扣件阻力小而且路基较差的路段释放能量,可能会发生钢轨严重变形,更甚者会发生胀轨跑道等严重铁道事故,为了避免发生如此事故,有必要定期对钢轨的温度应力进行检测。

3) jointless rail 点击朗读
