Abstract

PURPOSE:To uniformly cool a strip in the width direction extending its whole length, to improve the material quality and to prevent generating a faulty shape by bringing the centers of one pair of movable plates in line with the center position in the width direction of the strip. CONSTITUTION:The temp. difference T between the temp.s of the center part and end part on the strip 1 is calculated by a comparison arithmetic unit 20 and compared with a target temp. difference T0, when the T is larger than T0, a signal to narrow intervals between the movables plate 10 is transmitted to a control device 21 for a driving motor 13. At the same time, on the comparison arithmetic unit, the center position (C) of the strip 1 is calculated based on the both end positions detected through the output of the width direction thermometer 19. The signal to bring the center position of the strip in line with the center position of the one pair of the movable plates 10 is transmitted to a control device 22 for a transition mean 17 of a frame 12. In this way, the cooling temp. In the width direction of the strip 1 is controlled to the target temp. following to the meandering of the strip 1.
