摘　　要：轧机振动是国内外冶金行业备受瞩目的焦点问题。影响轧机振动加速度的因素很多,本文从磨辊圆度误差和轧制速度角度来研究影响轧机振动加速度问题。轧辊在磨床上进行磨削时,产生了磨辊圆度误差,有时会形成了多边形,上机使用时增加了轧机振动加速度,随着轧制速度的增加振动加速度也增加。通过对新辊和旧辊的动压靠实验得出:旧辊动压靠振动加速度比新辊动压靠振动加速度大。利用计算机仿真研究,建立了磨辊圆度误差与振动加速度之间的关系,从理论上解释了减小磨辊圆度误差可以降低振动加速度的理论依据。Rolling mill vibration is the focus of attention problems in metallurgical industry at home and abroad. There are many influence factors of rolling mill vibration acceleration. This article study relationship between roll roundness and the rolling mill vibration acceleration. The grinding roll roundness error is formed on the grinding machine. Roll polygons increase the rolling mill vibration acceleration. Through the roll press of old and new roll by experiment： old roll press vibration acceleration is larger than new roll press. It is set up that relationship between the vibration acceleration and grinding roll roundness error by means of computer simulation technology. Smaller roll roundness error can reduce the vibration acceleration.
