Research on Leveling Model of Combination Leveler

The evolvement of plate in 15-roller combination leveler has been studied in this paper using both geometrical analysis and FEM. The results show that the bending deformation and curvature evolvement are different from those obtained by general leveler. The technologies of parallel leveling and tension leveling are adaptive to the roll system of combination leveler, which not only can improve leveling precision, but also can erase the influence of negative torque on leveling roll, thus improving the leveling strength capacity of leveling materials. Meanwhile, a new calculating method of leveling process was pointed out, whose results were basically consistent to those of experimental results.
