According to the practical characteristics and parameters during hot finishing rolling process of aluminium alloy JP1235, a three-dimensional thermo-mechanical coupled elastic-plastic FEM model was established with the software Marc. And this model was used to simulate the rolling state of F1 stand without back tension. The lateral distribution of rolling force、contact friction force and other mechanic parameters were calculated. Meanwhile, simulated the rolling state considering the influence of mill tilt, and studied the distribution of the mechanics under this state, discussed the effect of mill tile on mechanic parameters and strip steering, which can provide some reference to steering control strategy.

根据JP1235铝合金板带热精轧过程的实际工艺特点和工艺参数，采用非线性有限元软件Marc，建立一个三维热力耦合弹塑性有限元模型，模拟了精轧机组第一机架（F1机架）失去后张力作用后的轧制状态，计算出轧制过程中轧制力、摩擦力等力能参数沿板宽方向上的分布情况，在此基础上，模拟初始轧辊倾斜影响下的轧制状态，并对该轧制状态下的力能参数分布情况进行研究，探讨轧辊倾斜对力能参数分布及跑偏规律的影响，为纠偏控制提供了一定的理论依据。
