  • Dynamic Model of the Hot Strip Rolling Mill Vibration

    The vibration demolding of the crystallizer leads to slab thickness deviation in continuous casting processes. Therefore, in this paper, the dynamic model of thehotstriprolling millvibration resulting from entry thickness deviation is proposed and its dynamic characteristics are studied. First, the dynamic model of vertical vibration in thehotstriprolling millis established based on ...
