Research on Force Simulation of Rolls' Deformation in the Rolling Process of Medium and Heavy Plate Leveler

摘要

During many factors affect the straightening precision, the shape of roller gap affect directly the flatness and the distribution of residual stress; At the same time, roll system's stiffness, as an important part of the roller leveler's whole stiffness, affect directly the design of leveling production process. In order to draw the conclusion of deformation characteristics and rules, the equivalent FEM Model on upper rolls and its support structure and investigates on the features of stress and strain after the rollers' deformation is established, based on the structural analysis of hot roller leveler for 3800mm plate steel.
