Abstract
ABSTRACT To investigate the problem of slab camber in rough rolling of hot strip mills, a 1580 mm roughing mill based on factors including the wedge of the incoming hot rolled slab, running deviation of the slab, the longitudinal stiffness difference between the two sides of the mill, and plane shape bending. Furthermore, the parameters of lateral flow in the model of plane shape control are systematically analysed. By using ABAQUS/Explicit, a roll-strip coupled dynamic finite element model is established and the simulation results of plane shape control are validated. After being used in a hot rolling mill, the hit rate of control of the slab camber is increased from 80.20 to 87.99%. The control level of the slab camber is improved and the problem of slab camber is relieved by the proposed camber control model. Theoretical analysis and field application results indicate that the camber control strategy is effective.
