Abstract

Die Erfindung betrifft eine Vorrichtung zur Erzeugung eines Wasservorganges zum Kühlen von durch den Wasser­ vorhang hindurchbewegten Blechen und Bändern. Sie bes­ teht aus einem Wasserkasten mit einer sich quer zur Bewegungsrichtung und über die gesamte Breite des Kühl­ gutes erstreckenden Schlitzdüse, deren Seitenwände den Düsenspalt begrenzend das im freien Fall mit laminarer Strömung austretende Kühlwasser führen. Man hat festges­ teilt, daß besonders bei großen Vorhangbreiten und hohen Fallhöhen Einschnürungen des Wasservorhanges auftreten, die zum Abreißen des Vorganges führen. Um einen laminaren Wasservorhang zu erreichen, schlägt die Erfindung vor, daß die Seitenwände (5, 6) der Schlitzdüse mindestens im Bereich der Auslassöffnung (10) quer zur Strömungsrichtung des Kühlwassers konvex gekrümmt sind. The invention relates to a device for generating a water process for cooling through the water sheets and strips moved through the curtain. You bes emerges from a water box with one across Direction of movement and across the entire width of the cooling good extending slot nozzle, the side walls of which Limiting the nozzle gap in free fall with laminar Lead cooling water emerging. You got stuck shares that especially with large curtain widths and high Fall heights constrictions the water curtain, which lead to the process being torn off. To a laminar To achieve water curtain, the invention proposes that the side walls (5, 6) of the slot nozzle at least in the area the outlet opening (10) transverse to the flow direction of the Cooling water are convexly curved.
