摘　　要：轧机的横向刚度和纵向刚度对于板带轧制而言非常重要,横向刚度直接决定着轧出的板形是否良好,纵向刚度对于板带纵向厚度控制具有重要意义。然而以往学者对于轧机刚度的研究大多停留在理论计算和数值模拟上,缺乏实验的支撑,因此本文主要通过实验的方法,在350 mm四辊可逆冷轧机上轧制不同宽度的工业纯铝板,研究了轧件宽度对轧机纵向刚度及轧机横向刚度的影响规律。并且在研究宽度的影响因素之前,首先研究了轧制速度对刚度的影响,并取得最优轧制速度,在最佳轧制速度下进行实验研究,实验结果显示板带轧制在速度较低并轧制和辊身相近宽度规格的板材时,所获得的厚度精度最高,板形最为良好。所得结论为得到良好的板形及厚度的精确控制具有基础性指导意义。The lateral and longitudinal stiffness of mill for strip rolling are very important , the former directly determines the shape of rolling whether are in good condition , while the latter is of important significance for the strip longitudinal thickness control .Most previous research rest on the theoretical calculation and numerical simulation, which were short of experimental support .This paper proposed an experimental test of industrial pure aluminum in 350 mm four roller reversible cold rolling with different width of strip width on rolling mill , vertical stiffness and horizontal stiffness effect rules are researched .After determined how rolling velocity effects stiffness, the optimal rolling speed is obtained .The experimental results show a phenomenon that exist two re-quirements, in low speed and similar width between the plate strip and the roll , to achieve high precision and good plate shape .This conclusion has significant fundamental guidance for accurate control of plate and thick -ness.
