Abstract

The invention relates to a cooling device (100) for cooling a metal strip (200) after a forming in a cold rolling stand (200) having at least one nozzle (112) for spraying a cooling medium (400) onto the surface of the metal strip (200). In order to make such known cooling device more effective and efficient, it is proposed according to the invention to provide a plate (500), which in an operating position is arranged parallel to the surface of the metal strip (200) in the run-out of the cold rolling stand (300,) and to arrange the nozzle in the operation position in such a manner that the cooling medium is sprayed at an acute spray angle α into a cavity between the surface of the metal strip and the opposing plate, with a spray direction (R) opposite to the running direction (L) of the metal strip.
