摘　　要：针对宝钢2050mm热轧带钢粗轧机组的轧制工艺条件,采用有限元法建立了热应力耦合二维温度场有限元仿真模型,并模拟了全过程。给出了带钢沿厚度方向各处温度随时间的变化曲线,得出了高压水除鳞、接触传热对板材温度场的影响模型。同时给出了各道次轧制力计算结果。模拟得到的粗轧段出口温度及轧制力与宝钢现场实测数据值相吻合。Aiming at rolling practices in roughing trains of 2050mm hot strip rolling of Baosteel,2-dimension rolling model for temperature field has been developed with the aid of FEM,and the whole rough rolling has been simulatedThe simulation results show that the curves of temperature change with rolling time along the thickness direction of steel,the high-pressure water descaling and contact transfer of heat affect the temperature field of steel as well as rolling forces at different passesThe surface temperature of steel at the exit of rough rolling and rolling forces are close to the measured values
