Description
Die Erfindung betrifft eine Kühlanordnung für die Sekundärkühlung einer Stranggussanlage für schwere Träger mit Sprühdüsen, die durch seitliche parallel zum Gießstrang verlegte Versorgungsleitungen mit einer Kühlflüssigkeit und mit Druckluft beaufschlagbar sind, wobei je eine jeder Anlagenseite zugeordnete Kühlflüssigkeit- und Druckluftleitung vorgesehen sind, die parallel zueinander verlegt und mit Anschlussflanschen zum Ansetzen von Anschlussplatten versehen sind, die fest mit den Sprühdüsen verbunden sind, wobei mit jedem Anschlussflansch je eine Anschlussplatte verbunden ist, die im Inneren mit einer Mischkammer versehen ist, über Verbindungskanäle mit den Versorgungsleitungen in Verbindung steht und einen Ausgangsstutzen aufweist, der mit einem Anschlussleitungsstück zu einer Sprühdüse verbunden ist.The invention relates to a cooling arrangement for the secondary cooling of a continuous casting plant for heavy carriers with spray nozzles, which are acted upon by lateral parallel to the casting strand supply lines with a cooling liquid and compressed air, each one each side of the plant associated cooling liquid and compressed air line are provided, which laid parallel to each other and are provided with connection flanges for attachment of connection plates, which are fixedly connected to the spray nozzles, wherein each connection flange is connected in each case to a connection plate which is provided internally with a mixing chamber, communicates via connecting channels with the supply lines and has an outlet connection, which is connected to a connecting piece to a spray nozzle.
Kühlanordnungen dieser Art sind bekannt. Fig. 3 zeigt eine solche Anordnung. Solche Rohrleitungs- und Düsenanordnungen zur Versorgung des Sekundärkühlsystems der Stranggussanlage sehen für eine Ausgestaltung mit zwei Düsen pro Seite mindestens drei Rohrleitungen vor. Eine Leitung liefert dabei, wie beispielsweise die Leitung L Druckluft, die durch ein T-Stück auf beide Sprühdüsen S geleitet wird und die beiden anderen Leitungen W liefern die Kühlflüssigkeit in Form von Wasser zu jeweils einer der Sprühdüsen. Diese drei Leitungen L und W verlaufen parallel zum Gießstrang S, der hier in die Form eines Doppel-T-Trägers innerhalb der Strangführung gebracht werden soll, in dem verschiedene Stützrollen R1, R2 und R3 für die Formgebung des Stranges S sorgen. Die Sprühdüsen D sind jeweils so angeordnet, dass sie in die Spalten zwischen benachbarte Rollen R1 sprühen und dabei möglichst die gesamte Seitenfläche des Stranges S mit ihrem Sprühstrahl berühren.Cooling arrangements of this type are known. Fig. 3 shows such an arrangement. Such piping and nozzle arrangements for supply of the secondary cooling system of the continuous casting plant provide for a design with two nozzles per side at least three pipes. A line supplies, such as the line L compressed air, which is passed through a tee on both spray nozzles S and the other two lines W supply the cooling liquid in the form of water to one of the spray nozzles. These three lines L and W are parallel to the casting strand S, which is to be brought here in the form of a double-T-beam within the strand guide, in which various support rollers R1, R2 and R3 provide for the shaping of the strand S. The spray nozzles D are each arranged so that they spray into the gaps between adjacent rollers R1 while touching as possible the entire side surface of the strand S with their spray.
Da die Zuführleitungen W und L parallel zum Gießstrang S verlaufen, müssen sie außerhalb des jeweiligen Segmentrahmens verlegt werden. Die Versorgung mit Druckluft und Wasser erfolgt über relativ dünne Leitungen L1, die entsprechend der Spritzrichtung gebogen werden müssen. Hierfür sind, wie Fig. 3 zeigt, mindestens drei der Stichleitungen L1, von denen zwei gebogen sind, notwendig und ein dazwischenliegendes Verteilerstück, das hier für die Druckluftversorgung vorgesehen ist, ebenso aber auch für die Wasserversorgung vorgesehen sein kann, wenn Druckluft durch die außenliegenden Leitungen W geführt wird.Since the feed lines W and L run parallel to the cast strand S, they must be routed outside the respective segment frame. The supply of compressed air and water via relatively thin lines L 1 , which must be bent according to the injection direction. For this purpose, as shown in FIG. 3, at least three of the branch lines L 1 , two of which are bent, necessary and an intermediate manifold, which is provided here for the compressed air supply, but also for the water supply may be provided when compressed air through the outside lines W is performed.
Eine solche Rohrleitungsanordnung ist relativ aufwendig zu installieren. Eine präzise Ausrichtung der Sprühdüsen D zur Zieloberfläche des Stranges S ist schwierig und je nach Qualität der Wartung ist auch die Gefahr groß, dass Bereiche des Stranges S beaufschlagt werden, die ungekühlt bleiben sollten. Außerdem ist der Ausbau einer einzelnen Düse zu Wartungszwecken ohne den Abbau der kompletten Versorgungsleitungen W, L nicht möglichSuch a piping arrangement is relatively expensive to install. A precise alignment of the spray nozzles D to the target surface of the strand S is difficult and, depending on the quality of the maintenance, there is also a great danger that areas of the strand S will be exposed, which should remain uncooled. In addition, the removal of a single nozzle for maintenance purposes without the removal of the entire supply lines W, L is not possible

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Kühlanordnung der eingangs genannten Art so auszugestalten, dass sie variabel einsetzbar, einfach in der Handhabung, der Montage sowie der Wartung und durch einen modularen Aufbau kostengünstig ist.The present invention is therefore the object of a cooling arrangement of the type mentioned in such a way that it can be used variably, easy to use, installation and maintenance and by a modular design cost.
Zur Lösung dieser Aufgabe werden die Merkmale des Patentanspruches 1 vorgesehen.To solve this problem, the features of
Erfindungsgemäß ist vorgesehen, dass das Anschlussleitungsstück gegenüber der Verlegungsebene der nebeneinander liegenden Versorgungsleitungen abgeknickt ist, dass das Anschlussleitungsstück lösbar am Anschlussstutzen der Anschlussplatte angesetzt und um 180° verdrehbar ist und dass die Anschlussplatten mit einer Regulierungseinrichtung zur Steuerung eines Druckluft/Kühlflüssigkeitsverhältnisses versehen sind..According to the invention, it is provided that the connecting line piece is bent relative to the laying plane of the adjacent supply lines, that the connecting line piece is detachably attached to the connection piece of the connection plate and rotated by 180 ° and that the connection plates are provided with a regulating device for controlling a compressed air / coolant ratio.
Diese Ausgestaltung bedingt nur zwei Rohrleitungen zur Versorgung der Sekundärkühlanlage mit Luft und Wasser. Unnötig werden ferner schwierig und aufwendig herzustellende gebogene Stichleitungen oder Verteilstücke. Es reicht das Anflanschen einer Anschlussplatte an die beiden Versorgungsrohre, die entsprechende Anschlussstellen aufweisen, wobei diese Anschlussplatten dann ihrerseits bereits die entsprechend ausgerichteten oder angeordneten Sprühdüsen tragen. Die Montage oder Demontage wird dadurch wesentlich einfacher.This embodiment requires only two pipes to supply the secondary cooling system with air and water. Needless are also difficult and expensive to produce bent stub lines or distributors. It is sufficient flanging a connection plate to the two supply pipes having corresponding connection points, these connection plates then in turn already carry the appropriately aligned or arranged spray nozzles. The assembly or disassembly is much easier.
Die Mischung von Kühlflüssigkeit und Druckluft wird erst in der Mischkammer innerhalb der Anschlussplatte vorgenommen und das Sprühgemisch wird dann zu der zugeordneten oder auch zu mehreren zugeordneten Sprühdüsen geliefert.The mixture of cooling liquid and compressed air is made only in the mixing chamber within the connection plate and the spray mixture is then supplied to the associated or even to several associated spray nozzles.
In einer Ausgestaltung der Erfindung ist das Anschlussleitungsstück lösbar am Ausgangsstutzen angesetzt und mit einer Verdrehsicherung versehen, die sicherstellt, dass die Anschlussleitungsstücke zu den Sprühdüsen nur in einer ganz bestimmten Stellung an den Ausgangsstutzen angesetzt werden können. Diese Ausgestaltung stellt daher die Ausrichtung des Sprühstrahles sicher, ohne dass eine Bedienungsperson in aufwendiger Weise diesen Sprühwinkel durch Biegen von Leitungen einstellen müsste. Es wird dadurch auch möglich, mit einem identischen Anschlussstück mit einer Sprühdüse beide Sprühpositionen zu verwirklichen.In one embodiment of the invention, the connecting line piece is detachably attached to the outlet nozzle and provided with a rotation, which ensures that the connecting line pieces can be attached to the spray nozzles only in a very specific position on the outlet nozzle. This embodiment therefore ensures the alignment of the spray jet, without an operator would have to adjust this spraying angle by bending lines in a complex manner. It is thereby also possible to realize both spray positions with an identical connection piece with a spray nozzle.
Bei einer Variante kann die Anschlussplatte fest mit zwei Distanzrohren verbunden werden, von denen eines mit der Druckluft und das andere mit der Kühlflüssigkeitsleitung in Verbindung steht, wobei die Distanzrohre in einem Flansch enden, der fest mit einem Düsengehäuse verbindbar ist, das mit zwei unter einem bestimmten Winkel zueinander und zu den Achsen der Distanzrohre stehenden Sprühdüsen versehen ist. Diese Sprühdüsen sind dabei in diesem Gehäuse mit einer Mischkammer und mit Kanälen zur Druckluft und Kühlflüssigkeitsführung verbunden. Auch die Anschlussplatte besitzt Durchgangsöffnungen zu den Distanzrohren, die abgedichtet an den Anschlussflanschen der Versorgungsrohre anliegen.In one variant, the connection plate can be firmly connected to two spacer tubes, one of which is in communication with the compressed air and the other with the coolant line, the spacer tubes terminate in a flange which is fixedly connected to a nozzle housing, with two under a certain angles to each other and to the axes of the spacer tubes standing spray nozzles is provided. These spray nozzles are in this case with a mixing chamber and connected to ducts for compressed air and coolant ducting. Also, the terminal plate has through holes to the spacer tubes, which bear sealed against the connecting flanges of the supply pipes.

Die Fig. 1 lässt erkennen, dass zwei Versorgungsrohre 1 und 2 jeweils mit quadratischem oder auch rechteckigem Querschnitt mit geringem Abstand zueinander in der Längsrichtung des Stranges S und parallel zu dessen Mittelebene 17 verlegt sind, der in gleicher Weise wie anhand von Fig. 3 schon erläutert, in einem Walzgerüst einer Stranggussanlage geführt und geformt wird. Die beiden Versorgungsleitungen 1 und 2, von denen eine zur Druckluftversorgung und die andere zur Kühlflüssigkeits-bzw. Wasserversorgung dient, sind durch in bestimmten Abständen angeordnete Laschen 3 auf der einen Seite und durch den Laschen 3 jeweils gegenüberliegende Anschlussflansche 4 untereinander verbunden und jeweils auf der Seite der Anschlussflansche 4 mit Öffnungen 1a bzw. 2a versehen, über die Druckluft oder Wasser jeweils in entsprechende Durchgangsöffnungen der Flansche eintreten kann.1 shows that two
An jeden Anschlussflansch 4 angesetzt ist dabei jeweils eine Anschlussplatte in der Form eines Flansches 5 einer Distanzrohreinheit 6, die aus zwei Distanzrohren 7 und 8 und aus einem weiteren Flansch 9 besteht, an dem wiederum mit Hilfe von Schrauben 10 ein Düsengehäuse 11 angeflanscht ist. Dieses Düsengehäuse 11 ist in nicht näher dargestellter Weise im Inneren mit einer Mischkammer versehen, in die Druckluft und Kühlflüssigkeit aus den Distanzrohren 7 und 8 eindringt und vermischt wird. Das Kühlmittel/Druckluftgemisch wird dann den beiden Sprühdüsen 12 und 13 zugeführt, die unter einem Winkel α zueinander ausgerichtet sind, der vorher auf die Form des Stranges S zusammen mit dem Sprühbild des Sprühstrahles 14 abgestimmt ist.Attached to each

Es ist ohne weiteres erkennbar, dass bei einer solchen Ausführungsform die Distanzrohreinheit 6 in einfacher Weise an den Flansch 4 angesetzt und mit Hilfe eines Schraubbolzens 15 befestigt werden kann, der durch die Flansche 4 und 5, durch den Spalt zwischen den Versorgungsrohren 1 und 2 und durch die Lasche 3 hindurch geführt wird. Dabei ist es möglich, eine präzise Ausrichtung der Distanzrohreinheit 6 und damit auch der Sprühdüsen 12 und 13 durch Passstifte 16 zu gewährleisten, die eine exakte Ausrichtung der Flansche 4 und 5 zueinander ermöglichen.It is readily apparent that in such an embodiment, the
Einleuchtend ist auch, dass bei dieser Ausführungsform nur zwei Versorgungsleitungen notwendig sind und dass die Wartung der Düsen 12, 13 wesentlich einfacher ist, weil zu diesem Zweck in einfacher Weise nach Lösen des Bolzens 15 die gesamte Distanzeinheit 6 mit dem Düsengehäuse 1 entfernt werden kann, ohne dass die Versorgungsleitungen 1, 2 demontiert werden müssten. Nach dem Wiederansetzen der Distanzrohreinheit sind die Sprühdüsen 12, 13 erneut exakt ausgerichtet, ohne dass umständliche Einstellvorgänge notwendig sind. Die Sprühdüsen 12, 13 bzw. deren Mundstücke sind am Düsengehäuse 11 zwangsausgerichtet, was auch für die Anordnung des Düsengehäuses 11 zur Distanzrohreinheit 6 und für die Ausrichtung der Distanzrohreinheit 6 zu den Versorgungsleitungen 1 und 2 gilt.It is also obvious that in this embodiment, only two supply lines are necessary and that the maintenance of the
Die Fig. 2 zeigt eine Variante einer erfindungsgemäßen Kühlanordnung. Hier sind wiederum die beiden Versorgungsrohre 1 und 2 parallel zueinander und nebeneinander und parallel zur Mittelebene 17 des Stranges S ausgerichtet. Sie sind hier aber auch nicht untereinander, sondern nebeneinander in einer horizontalen Verlegungsebene 25 angeordnet und sowohl auf ihrer Oberseite als auch auf ihrer Unterseite mit Flanschen 4 ausgerüstet, die wiederum über ihre Durchgangsöffnungen die Verbindung zur Druckluft und Kühlflüssigkeitsversorgung herstellen. An beiden Flanschen 4 sind jeweils die Anschlussplatten 18 angesetzt, über die jeweils eine Sprühdüse 19 versorgt wird, die mit einem abgeknickten Anschlussleitungsstück 20 versehen ist. Innerhalb der Anschlussplatte 18 ist hier in nicht näher dargestellter Weise jeweils eine Mischkammer vorgesehen, in der sich Druckluft und Kühlflüssigkeit vermischen und dann über einen Anschlussstutzen 21 und das Anschlussrohrstück 20 zu den Sprühdüsen 19 geführt werden. Auch in diesem Fall sind die Sprühstrahlen 14 auf die Form des Stranges S abgestimmt, was auch für den Knickwinkel des Anschlussleitungsstückes 20 gilt. Dieses Anschlussleitungsstück 20 ist dabei verdrehsicher mit dem Anschlussstutzen 21 der Anschlussplatte 18 verbunden und über eine Überwurfmutter gesichert, so dass das Anschlussrohrstück 20 nur in einer ganz bestimmten Lage an den Anschlussstutzen 21 ansetzbar ist. Die Sprühdüse 19 kann daher nur entweder in der oben gezeigten Lage oder in der unten gezeigten Lage ausgerichtet sein, wobei beide Positionen durch eine 180° Verdrehung der Anschlussplatten 18 zustande kommen. Die Anschlussplatten 18 können bei dieser Ausführungsform auch noch mit einer Reguliereinrichtung 22 zur Steuerung des Druckluft/Kühlflüssigkeitsverhältnisses versehen sein.Fig. 2 shows a variant of a cooling arrangement according to the invention. Here again, the two
Auch diese Ausführungsform ermöglicht eine leichte und präzise Montage oder Demontage dadurch, dass der Schraubbolzen 23, der jeweils die Anschlussplatte 18 am Flansch 4 hält, gelöst und die entsprechende Sprühdüseneinheit abgenommen, gewartet und dann wieder exakt angesetzt wird. Die verdrehsichere Verbindung zwischen Anschlussrohrstück 20 und Anschlussstutzen 21 und ihre Sicherung über eine Überwurfmutter 24 ist an sich bekannt und wird daher nicht im einzelnen erläutert. This embodiment also permits easy and precise assembly or disassembly in that the threaded
