Effects of Strip Thickness Difference on Deviation in Aluminum Hot Rolling

Abstract:

In aluminum hot rolling process, strip thickness difference plays a more important role in deviation. An FE model was presented to simulate the rolling process in which strip thickness difference was taken as a horizontal asymmetry factor of disturbance. Parameters information of nodes is processed, with the characteristic quantity of deviation and the asymmetrical thickness difference rate calculated. The result of simulation illustrates the deviation result under the disturbance of thickness difference, and the relationship among deviation function, characteristic quantity of deviation and the asymmetrical thickness difference rate. Deviation tracks under these circumstances are figured out. The effect of thickness difference on deviation in aluminum tandem hot rolling is revealed.
