Research on work roll contour for improving the flatness defect of electronic aluminum foil

Electronic aluminum foil strip has extremely large width-thickness ratio, and often emerges tight-edge and rib-wave defect after rolling. In order to improve the special flatness defect, the defect distribution characteristics, section profile of aluminum foil strip and defect cause are analyzed, and then a new work roll contour is designed based on the idea of partial variable diameter. The new contour curve is a combination of multiple curves and the influence of various curve parameters on the contour is researched. A finite element simulation model based on ABAQUS is established to study the control characteristics of flatness defect when using the new work roll. The simulation results and actual production data of the 1450 aluminum foil rolling mill show that the new work roll can increase the depression of tight-edge area and improve the flatness defect of tight-edge and rib-wave.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
