WATER-INJECTION CONTROL DEVICE IN ROLLING LINE, WATER-INJECTION CONTROL METHOD, WATER-INJECTION CONTROL PROGRAM

WIPO Patent Application WO/2011/092851

A1

The disclosed device is provided with: a cooling-water-use-condition prediction unit (11) that predicts the use conditions of cooling water within a predetermined prediction duration (T2) for each predetermined prediction cycle (T1); a constrained-running-condition prediction unit (12) that predicts the necessary running conditions of a pump unit (9) within the prediction duration (T2) in a manner so as to satisfy predetermined constraint conditions; a utilized-energy-quantity calculation unit (13) that calculates the quantity of utilized energy on the basis of the predicted running conditions of the pump unit (9); an optimization unit (14) that determines the optimal quantity of utilized energy among a plurality of quantities of utilized energy resulting from altering the running conditions of the pump unit (9); and a pump-unit-running control unit (15) that controls the running of the pump (9) with the running conditions of the pump unit (9) that result in the optimal quantity of utilized energy as a target value.
