Description
Die Erfindung bezieht sich auf eine Wasserkühlstrecke für die Kühlung von aus einer Walzenstraße herangeführtem Walzgut wie Draht oder Feinstahl mit mehreren, nebeneinander liegenden Kühlrohren, die unterschiedlich, den Querschnitten des Walzgutes angepaßte Innendurchmesser aufweisen und jeweils eine, aus einer geradlinigen Folge mehrerer Rohrabschnitte bestehende Kühlrohranordnung bilden, die gemeinsam auf einem, horizontal, quer zur Bewegungsbahn des Walzgutes verschiebbaren Träger angeordnet, wahlweise in diese Bewegungsbahn ein- und ausbringbar sind, wobei die Kühlwasserzufuhr zu den einzelnen Kühlrohrabschnitten über Kühlkopfdüsen und, diesen zugeordnete, zuflußsteuerbare Ventilanordnungen bewirkt wird.The invention relates to a water cooling system for the cooling of rolling stock brought out of a rolling mill such as wire or fine steel with a plurality of juxtaposed cooling tubes having different, the cross sections of the rolling stock adapted inner diameter and each form a, consisting of a straight line of several pipe sections cooling pipe arrangement , which are arranged together on a, horizontally, transversely to the movement path of the rolling slidable carrier, optionally in this trajectory and be brought out, wherein the cooling water supply to the individual cooling pipe sections via the cooling head nozzles and, associated, this inflow controllable valve arrangements is effected.
In der nicht vorveröffentlichten DE 199 60 638 ist eine Wasserkühlstrecke dieser Art beschrieben, die aus mehreren, parallel nebeneinander auf einem quer verschiebbaren Träger angeordneten Kühlrohren mit unterschiedlichen Innendurchmessern besteht, mit dessen Hilfe die Kühlrohre in die Bewegungsbahn des Walzgutes und aus dieser heraus bringbar sind. Die Kühlrohre sind mit dem Träger in einem Wasserkasten angeordnet und weisen einen gemeinsamen, an ihren Eingangsmündungen angeordneten Kühlkopf mit mehreren entsprechend dimensionierten, dem Kühlkopf zugeordneten Düsen für das Kühlwasser auf. Diesen Düsen ist ein Drehschieber vorgeordnet, der der jeweils in Arbeitsposition befindlichen Düse Kühlwasser zuleitet. Anstelle dieses Drehschiebers können, wie in dieser Druckschrift weiter ausgeführt wird, andere Steuereinrichtungen, z.B. Steilklappen, Schieberventile oder auch Einzelventile verwendet werden. Diese Ausbildungsform weist den Nachteil auf, dass das Auswechseln der Kühlrohre und der mit diesen verbundenen Kühlköpfe und Steuereinrichtungen einen erheblichen Bauaufwand mit sich bringt und für das Auswechseln erfahrenes Bedienungspersonal erfordert.In the non-prepublished DE 199 60 638 a water cooling section of this type is described, which consists of several parallel arranged side by side on a transversely displaceable support cooling tubes with different inner diameters, with the aid of the cooling tubes in the path of movement of the rolling stock and can be brought out of it. The cooling tubes are arranged with the carrier in a water tank and have a common, arranged at their entrance mouths cooling head with a plurality of appropriately sized, the cooling head associated nozzles for the cooling water. These nozzles are preceded by a rotary valve, which supplies cooling water to the respective nozzle located in the working position. Instead of this rotary valve can, as in this Reference is further executed, other control devices, such as steep flaps, slide valves or individual valves are used. This embodiment has the disadvantage that the replacement of the cooling tubes and associated with these cooling heads and control devices brings a significant construction costs and requires for the replacement of experienced operators.
Der Erfindung liegt die Aufgabe zugrunde, bei Wasserkühlstrecken dieser grundsätzlichen Ausbildung den Bauaufwand zu verringern und die Bedienung zu vereinfachen.The invention is based on the object of reducing the construction costs and simplifying operation in the case of water cooling sections of this basic design.
Ausgehend von einer bekannten, zum internen Stand der Technik gehörenden Wasserkühlstrecke, bei der eine Reihe von Kühlrohrabschnitten hintereinander in einem gemeinsamen Kühlwasserkasten angeordnet ist und mit den Eingangsmündungen der einzelnen Kühlrohrabschnitte Kühlköpfe verbindbar sind, die von Schraub-Halteelementen gehalten werden, wobei die Wasserversorgung der Kühlköpfe über separate Zuleitungsrohre und, außerhalb des Wasserkastens angeordnete Schnellschaltventile erfolgt, wird die obengenannte Aufgabe erfindungsgemäß dadurch gelöst, dass die Eingangs- und Ausgangsenden der einzelnen Rohrabschnitte der Kühlrohranordnung in selbstständige WasserkastenModule münden, die gemeinsam fest auf einem, den horizontal verschiebbaren Träger bildenden Wasserzuführrohr angeordnet sind. Dabei können in jedem der Wasserkastenmodule einzelne selbstständige, zwischen den Mündungen der jeweiligen Rohrabschnitte der Kühlrohranordnung auswechselbare und mit zugeordneten Schnellschaltventilen verbindbare Kühlkopfdüsenelemente verwendet werden. In den am Anfang und am Ende der Wasserkühlstrecke angeordneten Wasserkastenmodulen können dabei den Kühlkopfdüsenelementen ebenfalls auswechselbare Blasdüsenelemente vor- bzw. nachgeordnet werden, und des weiteren in diesen Wasserkühlmodulen Stellelemente zur Justierung dieser Kühlkopfdüsenelemente und Blasdüsenelemente vorgesehen werden. Die Wasserkastenmodule weisen zweckmäßig eine schwenk- und verriegelbare Abdeckung auf, in der spannbare Halteelemente für die Kühlkopfdüsenelemente und die Blasdüsenelemente angeordnet sind. Weiter können in den Wasserkastenmodulen pneumatisch oder hydraulisch betätigbare Schnellschaltklappen vorgesehen werden, die mit der Wasserzuführvorrichtung verbunden sind.Starting from a known, belonging to the internal state of the art water cooling system, in which a series of cooling pipe sections in a row is arranged in a common cooling water box and with the inlet mouths of the individual cooling pipe sections cooling heads are connected, which are held by screw-holding elements, the water supply to the cooling heads via separate supply pipes and arranged outside the water box quick-acting valves, the above object is inventively achieved in that the input and output ends of the individual pipe sections of the cooling pipe arrangement open into independent water tank modules, which are fixed together on a, the horizontally displaceable support forming water supply pipe , In this case, individual self-contained, replaceable between the mouths of the respective pipe sections of the cooling pipe arrangement and connectable with associated quick-switching valves cooling head nozzle elements can be used in each of the water box modules. In the arranged at the beginning and at the end of the water cooling section water tank modules while the cooling head nozzle elements also replaceable tuyeres can be upstream or downstream, and further provided in these water cooling modules actuators for adjusting these cooling nozzle elements and tuyeres. The water box modules expediently have a pivotable and lockable cover, are arranged in the tensionable retaining elements for the cooling head nozzle elements and the tuyere elements. Furthermore, pneumatically or hydraulically operable quick-action flaps, which are connected to the water supply device, can be provided in the water box modules.
Diese erfindungsgemäße Ausbildung der Wasserkühlstrecke erlaubt es, die in den einzelnen Wasserkastenmodulen befindlichen Kühlkopfdüsenelemente und auch die Blasdüsenelemente ohne Schwierigkeiten auszubauen und auszuwechseln. Ebenso können die zwischen den Wasserkastenmodulen angeordneten Rohrabschnitte ohne Schwierigkeiten ausgebaut und ausgetauscht werden. Da die einzelnen Kühlrohranordnungen durch die Querverschiebung des Tragrohres in und außer Betriebsposition bringbar sind und jede für sich über die Schnellschaltventile mit Kühlwasser versorgt werden kann, sind für solche Auswechselarbeiten nur kurze Unterbrechungen des das Walzgut zuführenden Walzbetriebs notwendig.This inventive design of the water cooling section makes it possible to expand and replace the cooling head nozzle elements located in the individual water box modules and also the blowing nozzle elements without difficulty. Likewise, arranged between the water tank modules pipe sections can be removed and replaced without difficulty. Since the individual cooling tube arrangements can be brought into and out of the operating position by the transverse displacement of the support tube and each can be supplied with cooling water via the quick-acting valves, only brief interruptions of the rolling operation feeding the rolling stock are necessary for such replacement operations.

In den eingangsseitig oder ausgangsseitig der Wasserkühlstrecke angeordneten Wasserkastenmodulen WKMa und WKMb sind zusätzlich zu den Kühlkopfdüsenelementen KDE1 und KDE2, vor- bzw. nachgeordnet, Blasdüsenelemente BLE1, BLE2 und BLE3, ebenfalls auswechselbar einsetzbar; sie können dabei mit den gleichen Mitteln gehalten werden wie die Kühlkopfdüsenelemente KDE. Diese Kühlkopfdüsenelemente und die Blasdüsenelemente können, nachdem sie eingesetzt worden sind, auf nicht dargestellte Weise mit Hilfe von Gewinden und Führungen oder Spannmuttern gegen Anschläge justiert werden. In den Wasserkühlmodulen WKM lassen sich ferner pneumatisch oder hydraulisch betätigbare Schnellabschaltklappen zur Unterdrückung von Druckstößen aus dem Wasserzuführrohr WZR anordnen.In the water box modules (see also Fig. 3) are supported on the Wasserzuführrohr WZR Schnellschaltventile SSV1, SSV2, SSV3 arranged on the respective Kühlkopfdüsenelemente KDE1, KDE2, KDE3 are replaceable placed; they can be releasably secured in a manner not shown by means of pneumatically or hydraulically operable cylinder units, springs, wedges or screws or also, as shown, held by a clamping element SP, which is connected to a hinged to the water tank module WKM cover AD. In the input side or output side of the water cooling section arranged water tank modules WKMa and WKMb are in addition to the cooling head nozzle elements KDE1 and KDE2, upstream or downstream, Blasdüsenelemente BLE1, BLE2 and BLE3, also interchangeable used; they can be held by the same means as the cooling head nozzle elements KDE. These cooling head nozzle elements and the tuyere elements, after being inserted, can be adjusted in a manner not shown by means of threads and guides or clamping nuts against attacks. In the water cooling modules WKM can also be arranged pneumatically or hydraulically actuated Schnellabschaltklappen for the suppression of pressure surges from the water supply pipe WZR.
