摘　　要：通过有限元方法建立二辊铝板带热轧机轧辊的热-结构耦合模型,分析精轧阶段轧辊热凸度的变化规律,以及不同轧制因素对热凸度的影响。结果表明,轧制间歇时间在40s时对热凸度的改变量占间歇时间为100s时总的热凸度改变量的60.5%;通过分析,得出影响轧辊热凸度重要性的因素依次是冷却液流量、轧制间歇时间、轧制速度.A finite element model of work roll’s thermal-structure is established.The change and the effect factors of thermal crown are studied in finishing stage.When the rolling speed is more than 2m/s,it has little effect on the thermal crown.Rolling Intermittent time in the 40 s,the change quantity of the work roll thermal crown accounted for about 60.5%of total thermal crown change quantity.When the influence of coolant flow on the size of cooling zone is ignored,the result shows that the cool water flow has a strong control ability of thermal crown of work roll,it is concluded that the importance of the factors on the thermal crown is respectively cool water flow,intermittent time of rolling,rolling speed.
