摘要：

应用CAE大型通用有限元分析软件ABAQUS，采用热力耦合大变形模拟方法，对热连轧板带7道次精轧过程进行了数值模拟。以某钢铁厂现场实际生产数据为基础，设计板带连轧仿真模型，并定义工艺参数，模拟了板带热连轧精轧机组的生产过程。针对板带在热连轧过程中的变形、应力应变云图和金属流动规律做了模拟分析与计算。计算结果表明，模拟计算数据与现场实测数据基本吻合，为热连轧板带的生产工艺制定提供了可靠的数值模拟依据。

Applying the major general CAE finite element analysis software ABAQUS and using coupled large deformation thermo-mechanical simulation method, the finishing rolling process of strip hot continuous rolling with seven passes was simulated. Based on the field production data of a certain steel works, the strip continuous rolling model was designed and the process parameters were defined, then the production process of finishing mill group of strip hot continuous rolling was simulated. For the strip deformation，stress and strain contours and the law of metal flow during the deformation of strip hot continuous rolling, the calculation and analysis were done. The results show that the simulated data is basically consistent with the practical production data, which provides a reliable numerical simulation foundation for making process of strip hot continuous rolling production.
