本发明公开了种避免钢轨磨伤黑印的方法，解决通过定载荷技术消除钢轨残余应力生产中，钢轨与工作辊之间打滑形成磨伤黑印的问题，采用的技术方案是：通过消除残余应力装置配合矫直机实施，消除残余应力装置的电机和减速机之间由超越离合器相连；生产过钢方向上：当消除残余应力装置的工作辊线速度低于或等于钢轨通过速度时，超越离合器为超越状态；当消除残余应力装置的工作辊的线速度高于钢轨通过速度时，超越离合器为结合状态；生产过钢的反方向上：在矫直机反向转动前关停消除残余应力装置的电机的始能，电机处于可自由空转的状态。通过考虑生产过钢的方向以及反方向上的情形，采用不同控制方式，避免钢轨表面出现磨伤黑印，且投资低维护省。
