Vorrichtungen dieser Art sind aus FR-A-1 449 608 und JP-A-55-42 146 sowie JP-A-60-221 624 bekannt. Bei der Ausbildung nach der erstgenannten Druckschrift bestehen die Zentrierlineale aus kastenförmigen, in Richtung auf den profilierten Träger und von diesem weg verschiebbaren Hohlkörpern. Deren einander zugewandte vertikalen Seitenwände weisen eine Reihe von, im Abstand einzeln nebeneinanderliegenden Kammern auf, die in Richtung auf den, zwischen den verschiebbaren Hohlkörpern bewegten profilierten Trägern offen sind und jeweils winkelförmig, um eine horizontale Mittenachse schwenkbare Zuführstutzen mit den Sprühdüsen aufnehmen. Die Höhenposition der Sprühdüsen lässt sich dabei durch eine Schwenkbewegung der Zuführstutzen verändern und der Höhe des jeweils zu kühlenden profilierten Trägers anpassen. Die Zufuhr der Sprühflüssigkeit zu den einzelnen Zuführstutzen der Sprühdüsen erfolgt über eine gemeinsame, fest in dem kastenförmigen Hohlkörper angeordnete Zuführleitung.Devices of this type are known from FR-A-1 449 608 and JP-A-55-42 146 and JP-A-60-221 624 known. When training according to the first-mentioned publication the centering rulers consist of box-shaped, towards the profiled Carrier and hollow bodies displaceable therefrom. Their facing each other vertical sidewalls have a series of spaced-apart adjacent Chambers that are sliding towards, between, the Hollow bodies moving profiled beams are open and each angular feed pipe with pivotable about a horizontal central axis take up the spray nozzles. The height position of the spray nozzles can be changed by swiveling the feed pipe and changing the height of the Adapt each profiled beam to be cooled. The supply of the spray liquid to the individual feed nozzles of the spray nozzles takes place via a common, supply line fixedly arranged in the box-shaped hollow body.
Diese Ausbildungsform der Kühlvorrichtung erfordert für jede der Einstellpositionen der Sprühdüsen an profilierten Trägern unterschiedlicher Höhen einen erheblichen Bedienungsaufwand, weil jede der Sprühdüsen mit ihrem Zuführstutzen für sich von Hand verstellt werden muss. Die Verstellung erfordert dabei sowohl Erfahrung als auch Geschicklichkeit des Bedienungspersonals und besondere Werkzeuge, weil sich Zuführstutzen und Sprühdüsen in einer verhältnismäßig engen, durch den Walzbetrieb meist verschmutzten Kammer befinden. Hinzu kommt die schwierige Zugänglichkeit der Kammer wegen deren Position dicht über dem Rollgang. Nachteilig wirkt sich auch die aus diesen Schwierigkeiten resultierende verhältnismäßig lange Stillstandszeit der Zentrierlineale aus, die häufig größer ist als die Umstellzeit bei der die profilierten Träger zuführenden Walzstraße bei Änderung des Walzprogramm auf andere profilierte Träger.This design of the cooling device requires for each of the setting positions the spray nozzles on profiled beams of different heights a considerable Operating effort because each of the spray nozzles with their feed nozzle for has to be adjusted by hand. The adjustment requires both experience as well as skill of the operating personnel and special Tools because the supply nozzle and spray nozzle are in a relatively narrow, Chamber is mostly dirty due to the rolling operation. Come in addition the difficult accessibility of the chamber because of its position just above the Roller table. The resulting from these difficulties also has a disadvantage relatively long downtime of the centering rulers, which is often larger than the changeover time on the rolling train feeding the profiled beams when changed of the rolling program on other profiled beams.

Ausgehend von dem weiteren, aus WO-A-92/19395 bekannten Vorschlag, die Sprühdüsen gemeinsam zu verstellen, wird diese Aufgabe dadurch gelöst, dass die Innenwände der offenen Kammern in Richtung auf die Rückwand der kastenförmigen Hohlkörper der Zentrierlineale trichterförmig verjüngt in eine, in dieser vorgesehene Öffnung auslaufen, und die, in der Kammer befindlichen Zuführstutzen der Sprühdüsen fest mit der, hinter dieser Öffnung angeorneten, um ihre Längsmittenachse drehbar gelagerten gemeinsamen Zuführleitung verbunden sind., wobei die Zuführstutzen der Sprühdüsen, radial auf dessen Umfang aufstehend, mit dem gemeinsamen Zuführleitungsrohr verbunden sind, dessen, parallel zur Zentrierliie des Zentrierlineals verlaufende Mittenachse mit einer Dreh-stelleinrichtung verbunden ist mit der vorgegebene Drehpositionen des Zuführleitungsrohres und mit diesem entsprechende Winkelstellungen der Zuführstutzen und deren Sprühdüsen einstell- und festlegbar sind. Based on the further proposal known from WO-A-92/19395, to adjust the spray nozzles together, this will Problem solved in that the inner walls of the open chambers in Direction towards the rear wall of the box-shaped hollow bodies of the centering rulers funnel-shaped tapering into an opening provided in this, and the, supply nozzle of the spray nozzles located in the chamber with the one behind it Opening arranged to be rotatably mounted around its longitudinal central axis Feed line are connected., With the feed nozzle of the spray nozzles, standing up radially on its circumference, with the common one Feed pipe are connected, its parallel to the centering the center axis of the centering ruler with a turntable is connected to the specified rotational positions of the feed pipe and with this corresponding angular positions the feed nozzle and its spray nozzles can be set and fixed are.
Mit dieser erfindungsgemäßen Ausbildungsform der Kühlvorrichtung wird die Möglichkeit geschaffen, durch eine einfache Drehschwenkbewegung der Zuführleitung um deren Längsmittenachse die Stelihöhe sämtlicher, in dem Zentrierlineal angeordneten Zuführstutzen mit ihren Sprühdüsen gemeinsam zu ändern und einzustellen, ohne dass es dazu eines Eingriffs in die einzelnen Kammern bedarf. Der Zeitaufwand für diese Einstellung ist so minimal, dass die Verstellung sogar während des Betriebes beim Durchlauf der profilierten Träger vorgenommen werden kann. With this embodiment of the cooling device according to the invention, the possibility becomes created by a simple pivoting movement of the feed line around their longitudinal center axis, the post height of all of them arranged in the centering ruler Change and adjust the feed nozzle with their spray nozzles together, without any intervention in the individual chambers. The The time required for this setting is so minimal that the adjustment can even be made during operation during the passage of the profiled beams can.
