Abstract
In an endless rolling line, a speed of a material to be rolled changes with a flying thickness change. A temperature control device executes predictive calculation of a speed change amount of the material to be rolled associated with the flying thickness change and updates a speed pattern. The temperature control device executes feedforward control of an amount of a coolant to cool the material to be rolled based on a latest speed pattern and a measured temperature value of the material to be rolled in an entry side of the heat exchanger. In parallel with the feedforward control, the temperature control device executes feedback control of coolant volume based on an error between the measured temperature value of the material to be rolled in the delivery side of the heat exchanger and a target value.
