Abstract:The finite element simulation model of strip with edge wave characteristics was established for roll straightening process. The accuracy of finite element model was verified by comparing the measured straightening force with that calculated by the finite element model, and the error of two values was less than 10%. The original curvature compensation method and plastic deformation layer method were used to determine 4 kinds of roll bending settings. The strip with wave height of 20 mm was straightened by above schemes and the flatness of strip after straightening was compared. It is concluded that the straightening effect of roll bending amount calculated by original curvature compensation method according to the highest wave height is the best. At the same time, the straightening force increases with increase of roll bending amount, which provides a basis for straightening process of edge wave on site.
