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。利用ANSYS/LS-DYNA显式动力分析软件,在热连轧过程中张力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分析,得出了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,可以为轧制工艺的制定提供参考依据。As it is difficult to obtain the internal metal movement of the rolling piece by experimental methods in the actual hot-strip rolling production process.ANSYS/LS-DYNA as the large-scale finite element analysis software is applied to Simulate the Internal metal movement of the rolling piece in hot strip rolling Process with different tension.Obtain the internal metal movement of the rolling piece Influence of Tension from the analyzes of node displacement vector and rolling force.Result proved coincide with the spot data,can be formulated as a reference during the rolling process.
