摘　　要：根据物理冶金组织演变规律和经验公式,开发了金属热变形过程耦合组织演变的计算模块。结合某厂2050热带钢连轧工艺过程,利用非线性刚塑性有限元法,建立热连轧过程热、力、组织的多参量耦合仿真模型。运用该模型对2050现场实际轧制过程进行模拟计算,分析了轧制过程轧件变形场、温度场及显微组织的演变规律。模拟得到的轧制力能参数、温度、组织分布与实测数据基本一致。Based on physical metallurgy microstructural evolution rule and experiential expres sions, calculation module of coupling microstructural evolution of metal hot deformation process had been developed. Taking 2050 mill hot strip continuous rolling process as an object,a coupling thermal, mechanical and microstructural simulation model on hot continuous rolling was built by using nonlinear rigid plastic finite element method（FEM）. After an actual rolling process of 2050 mill was simulated by using the model, evolution laws of strain field, temperature field and microstructure were an alyzed. Simulated rolling force, temperature value and microstructure are of good agreement with the measured results.
