Abstract
Steel strip is cooled, in a continuous annealing furnace, by passing it around rolls through which a cooling medium is circulated. Temp. distribution acess the width is detected by a thermometer at the outlet from the cooling rolls. Readings are taken at edges and centre of the strip. These are used in feedback control of a gas jet cooler at the inlet to the first cooling roll. It is subdivided into ducts, opened or closed to vary the blowing width. An operational controller calculating temp. deviation across the strip can be used to actuate the cooler when the deviation exceeds a predetermined figure.
