Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An energy-saving device for a rolling plant, comprising: a first rolling stand for rolling the material being rolled of a metallic material conveyed on a rolling line; a second rolling stand arranged on the downstream side of the first rolling stand; a third rolling stand arranged on the downstream side of the second rolling stand; a first inter-stand cooling system which is provided between the first rolling stand and the second rolling stand to pour cooling water onto the conveyed material being rolled; a second inter-stand cooling system which is provided between the second rolling stand and the third rolling stand to pour cooling water onto the conveyed material being rolled; and a controller configured to: change an operating mode of the rolling plant from a state in which the second rolling stand rolls the material being rolled and a state in which the second rolling stand does not roll the material being rolled according to a product specification of the material being rolled; and prohibit the first inter-stand cooling system from pouring cooling water and permit the second inter-stand cooling system to pour cooling water in a state in which the first rolling stand and the third rolling stand roll the material being rolled and the second rolling stand does not roll the material being rolled.
