Title:
圧延ラインにおける注水制御装置、注水制御方法、注水制御プログラム
Document Type and Number:
Japanese Patent JP5492910
Kind Code:
B2
Abstract:
A water injection controller and method usable in rolling lines using stored cooling water to cool a material. A cooling water usage predictor predicts, for a respective prescribed prediction cycle, usage of cooling water in a prescribed prediction target period. A constrained running condition predictor takes the predicted cooling water usage to predict a required running condition of a pump system in the prediction target period meeting a prescribed constraint condition. An energy consumption calculator takes the predicted running condition of the pump system to calculate an energy quantity to be consumed. An optimizer determines an optimal energy quantity to be consumed among plural energy quantities to be consumed under changed running conditions of the pump system. A pump system running controller controls running of the pump system having as a target value therefor a running condition of the pump system requiring the optimal quantity of energy to be consumed.
