无缝线路与普通线路相比,钢轨内部存在着很大温度力,因此防止长钢轨折断的胀轨跑道是非常重要的工作。而长钢轨的锁定轨温是无缝线路的重要参数,它决定钢轨内部力的大小,特别是寒冷地区的我局,一年四季气温变化幅度大,准确确定锁定轨温,才能防止冬季钢轨被拉断和夏季胀轨跑道。 Seamless lines have a large temperature force inside the rail as compared to normal lines, so it is an important task to prevent the rail from breaking off. The long rail rail temperature rail locking is an important parameter of the seamless line, which determines the size of rail internal force, especially in cold areas of our bureau, a large temperature changes throughout the year, accurately determine the locking rail temperature, to prevent the winter rail Tensioned and summer expanse track runway.
