Rolling Control Device

Abstract: In the present invention, during rolling, a first actual results collection unit collects first exit-side sheet thickness measured values at a first management point of a rolling material, and rolling load measured values for each stand. During the rolling of the rolling material, a second actual results collection unit collects second exit-side temperature measured values at a second management point, which is farther toward the tail end side than the first management point. After the rolling of the rolling material, a first training unit trains a deformation resistance model, a rolling load model, and a mill elongation model on the basis of the first exit-side sheet thickness measured values and the rolling load measured values. After the rolling of the rolling material, a second training unit trains a temperature model on the basis of the second exit-side temperature measured values. Before rolling of the next material, a setting calculation unit calculates a roll gap setting value, a roll peripheral speed setting value, and a cooling water amount setting value, using the deformation resistance model, the rolling load model, and the mill elongation model that were trained by the first training unit, and the temperature model that was trained by the second training unit.
