ENERGY-SAVING DEVICE FOR ROLLING PLANT

摘要

An object of the present invention is to provide 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 24 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 50 that are provided between the plurality of rolling stands 24 to pour cooling water onto the conveyed material being rolled. The inter-stand cooling systems 50 are configured so that the pouring amount of cooling water poured from the inter-stand cooling system 50 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 50 positioned on the downstream side is smaller.
