Abstract

Provided is a cooling device wherein water is drained appropriately to cope with even an increase in the water volume density of cooling water to thereby ensure high cooling capability. A cooling device is provided with a plurality of cooling nozzles which are disposed downstream from a hot finished rolling mill line are capable of supplying cooling water toward a pass line from above and are arranged in the direction of the pass line and an upper surface guide which is disposed between the pass line and the cooling nozzles. The cooling device is characterized in that when the water volume density of the cooling water to be jetted is set to q (m/(m·sec)) the pitch between the cooling nozzles in the direction of the pass line is set to L (m) the distance between the lower surface of the upper surface guide and the pass line is set to h (m) the homogeneous cooling width is set to W (m) and the cross sectional area of a virtual flow path of drainage water flowing in the direction of the width of a steel sheet per pitch between the cooling nozzles in the direction of the pass line is set to S (m) a predetermined relationship is established.
