PROBLEM TO BE SOLVED: To provide equipment and a method for cooling a steel plate by which cooling water is uniformly supplied in the width direction of the steel plate and the whole steel plate is cooled uniformly even when the thickness of the steel plate is varied in the hot-rolling line of the steel plate. SOLUTION: In full width nozzle trains 22<SB>-1</SB>to 22<SB>-6</SB>, by changing the arrangement of a nozzle train facing the left end and a nozzle train facing the right end little by little, injection direction branch points P1-P6 are shifted byδeach in the width direction of the steel plate.
