Quarterwave flatness defect often appears in the DP980 cold rolling process, seriously affecting product quality. To find the causes of this kind of flatness defect, a multipass finite element model (FEM) based on a 2130 UCM mill was established, and the accuracy of the model was verified by three methods. The simulation results of the S3 and S4 stands show that the deviation between the ...
