A method using the finite element simulation for determining coiling conditions of intermediate plates in a coilbox installed between roughing and finishing stands of hot strip rolling is proposed. The coilbox has the function of preventing the drop in temperature due to the radiation from the surface of the plate in the waiting between the roughing and finishing stands, because the surface area is considerably reduced by coiling the plate. In the present method, non-steady-state deformation of the plate in the coilbox is simulated by the finite element method, and the rolls are appropriately moved in accordance with the simulated results to bend the plate circular. Since the formation of the coil is influenced by the formed shape near the front end of the plate, the deformation behavior near the front end is monitored during the finite element simulation, and the positions of the rolls for coiling the plate are determined from the monitored shape. In addition, the coiling of plates becomes stable due to the control of the rotation of the roll for forming the front end.
