A control device for a rolling plant, which is capable of reducing the pouring amount of cooling water by pouring cooling water at timing of high cooling efficiency when a material being rolled is cooled, and thereby being capable of saving the energy consumption. The control device includes a plurality of rolling stands that are arranged in tandem on a rolling line to roll the material being rolled of a metallic material conveyed on the rolling line, and inter-stand cooling systems that are provided between the plurality of rolling stands to pour cooling water onto the conveyed material being rolled. The inter-stand cooling systems are configured so that the pouring amount of cooling water poured from the inter-stand cooling system positioned on the upstream side on the rolling line is larger, and the pouring amount of cooling water poured from the inter-stand cooling system positioned on the downstream side is smaller. |
