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.
