Abstract

Roll leveling is a technological process of metal forming, used to minimize the flatness of sheet plates and reduce the level of residual stresses. The report presents the design of a 13-roll leveler for straightening sheet plates of complex configuration. The straightening precision is directly affected by the stiffness of the leveler housing. To determine the characteristics and patterns of deformation, the equivalent finite element model of the leveler housing are established and then the features of stress and strain about the leveler housing are studied.
