摘　　要：在实际的板带轧制生产过程中,轧件内部的金属流动情况是很难通过实验的方法得到。本文利用ANSYS/LS-DYNA显式动力分析软件,在张力热连轧过程中,对轧件内部的金属流动影响进行了有限元模拟。对板带材轧制过程中节点的位移矢量和轧制力进行了分析,得出张力对轧件内部金属流动的影响规律,计算结果与现场数据基本吻合,为轧制工艺的制定提供参考。As it is difficult to obtain the metal movement inside the rolling piece in the actual hot-strip rolling production process by experimental methods,ANSYS/LS-DYNA as the large-scale finite element analysis software is adopted to simulate the influence of tension produced in hot strip rolling process on metal movement inside the rolling piece.The influence law of tension on the metal movement inside the rolling piece was obtained by the analyzsis of node displacement vector and rolling force in hot strip rolling process.The calculated result coincides basically with the spot data.It provides a reference for the design of the rolling process.
