Flatness is one of the most important qualities of plates. Most plates just after the rolling or cooling process, however, do not satisfy the flatness demand for customers. As the most particular flatness defects, edge wave and center buckle are well-known. In order to satisfy flatness limits, roller leveler is widely applied. In the roller leveling, the plastic deformation ratio that represents the magnitude of bending is the most important parameter for its leveling effect.However, leveling effect of edge wave and center buckle sometime varies though the equal plastic deformation ratio is given in the practical operations. This work investigates and discusses the influence of edge wave length on leveling effect through a three-dimensional FE analysis.
