摘　　要：建立了热轧C-Mn钢奥氏体再结晶、流变应力、晶粒尺寸和相变的预测模型,并利用对宝钢2050热连轧及层冷卷取过程温度场的模拟结果定量分析了不同C、Mn含量对组织演变的影响。结果表明,预测值与实测值符合得较好,该模型可用于热轧带钢生产线的预测和控制。A model was developed to predict the dynamics of dynamic and static recrystallization, grain size, flow curves and phase transformation of hot rolled C-Mn steel. The model quantifies the influences of carbon and manganese element on microstructure evolution by using of the simulated data of temperature field during hot rolling, cooling and coiling of 2050 tandem mill. The results show that the calculated values are matched to the measured ones. This model can be applied to predict and control the hot strip rolling process.
