Abstract

Um eine Kühlvorrichtung für fertiggewalzte Profile, insbesondere Stahlträger, bereitzustellen, die bei Änderung des Walzprogramms auf unterschiedlicher Geometrien und Größen der Profile einstellbar ist und eine gleichförmige Kühlung aller Profile bzw. definierter Teilbereiche gewährleistet, wird eine Vorrichtung vorgeschlagen, die Kühlbereiche aufweist, wobei jeweils ein Kühlbereich von dem zu kühlenden Profil (5, 6) aus betrachtet zu diesem oberhalb (1), zu beiden Seiten (3) und unterhalb (2) angeordnet ist, wobei die Kühlbereiche jeweils einzeln oder kombiniert einsetzbar sind, und ein Kühlbereich jeweils aus mindestens einer Düse (7) oder einem Düsenverband besteht, und die Düsen einzeln oder im Verbund steuerbar sind.

Figure 00000001
In order to provide a cooling device for finished rolled profiles, in particular steel girders, which can be set to different geometries and sizes of the profiles when the rolling program is changed and which ensures uniform cooling of all profiles or defined partial areas, a device is proposed which has cooling areas, one in each case Cooling area viewed from the profile (5, 6) to be cooled is arranged above (1), on both sides (3) and below (2), the cooling areas being usable individually or in combination, and a cooling area each consisting of at least one there is a nozzle (7) or a nozzle assembly, and the nozzles can be controlled individually or in combination.
