Abstract

This dewatering device for cooling water for hot rolled steel sheets i s a dewatering device for dewatering cooling w a ter sprayed on a hot rolled steel sheet at a water volume density of more than 4 m3 /m 2/min to 10 m3 /m 2/min or less when the hot rolled steel sheet i s cooled after finish rolling i n the hot rolling process. The device i s provided with multiple dewatering nozzles for spraying dewatering water on the hot rolled steel sheet. O n the surface of the hot rolled steel sheet, the impact regions of the dewa - tering water sprayed fiOm each of the dewatering nozzles form a continuous straight line in the width direction of the hot rolled steel sheet and portions of mutually adjacent impact regions overlap.
