Abstract

The disclosure of the present invention relates to a strip temperature control method and apparatus for a finishing train of a hot strip rolling mill, including strip interstand coolant supply means, and a control for varying the rate of flow thereof, which includes a feed-forward control signal wherein the rate of flow is controlled in certain stands with reference to a computed temperature and a desired temperature of the strip as it leaves the train, and a feed-backward control signal wherein the rate of flow is controlled in one or more stands with reference to the actual temperature and a desired temperature as it leaves the train.
