Description

Die Erfindung betrifft eine Kühlanordnung für das Walzgerüst einer Stranggussanlage für schwere Träger mit Sprühdüsen, die durch seitliche in Längsrichtung des Walzgerüstes verlegte Versorgungsleitungen mit einer Kühlflüssigkeit und mit Druckluft beaufschlagbar sind.The invention relates to a cooling arrangement for the rolling mill of a Continuous casting plant for heavy carriers with spray nozzles, which through lateral in the longitudinal direction of the rolling mill laid supply lines can be acted upon with a cooling liquid and compressed air.

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 des Walzgerüstes gebracht werden soll, in dem verschiedene Walzen 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 Walzen 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 the secondary cooling system of the continuous casting plant see for an embodiment with two nozzles per side at least three pipelines before. A line provides, such as the line L compressed air, the passed through a tee on both spray nozzles S and the two other lines W supply the cooling liquid in the form of water one each of the spray nozzles. These three lines L and W run parallel to the cast strand S, here in the shape of a double-T beam is to be brought within the rolling stand in which different Rolls R1, R2 and R3 for the shaping of the strand S care. The Spray nozzles D are each arranged so that they are in the gaps between spray adjacent rolls R1 while keeping as much as possible Touch the side surface of the strand S with its spray jet.

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 möglich.Such a piping arrangement is relatively expensive to install. A precise alignment of the spray nozzles D to the target surface of the Stranges S is difficult and depending on the quality of maintenance is also the Danger big that areas of strand S are being impinged upon should remain uncooled. In addition, the expansion of a single nozzle for maintenance purposes without dismantling the complete supply lines W, L not possible.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Kühlanordnung der eingangs genannten Art so auszugestalten, dass ihr Aufbau einfacher und betriebssicherer ist und dass auch der Montageund Installationsaufwand so gering wie möglich gehalten werden kann.The present invention is therefore based on the object, a Cooling arrangement of the type mentioned in such a way that you Construction is simpler and more reliable and that also the Montageund Installation costs can be kept as low as possible.

Zur Lösung dieser Aufgabe wird bei einer Kühlanordnung der eingangs genannten Art vorgesehen, dass jeder Walzgerüstseite nur je eine Kühlflüssigkeit- bzw. Druckluftleitung zugeordnet wird, die parallel zueinander verlegt und mit Anschlussstellen zum Ansetzen von Anschlussplatten versehen sind, die fest mit den Sprühdüsen verbunden sind.To solve this problem is in a cooling arrangement of the above provided that each rolling mill side only ever a Kühlflüssigkeit- or compressed air line is assigned, which are parallel to each other laid and with connection points for attaching connection plates are provided, which are firmly connected to the spray nozzles.

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 further difficult and expensive to produce bent stub lines or Verteilstücke. It is sufficient to flanging a connection plate to the two supply pipes, which have corresponding connection points, these connection plates then in turn already the corresponding wear aligned or arranged spray nozzles. The assembly or disassembly is much easier.

In Weiterbildung der Erfindung können dabei die Anschlussstellen an den Versorgungsleitungen als Flansch ausgebildet sein, an die die Anschlussplatten in einfacher Weise ansetzbar sind. Vorteilhaft ist es auch, die beiden Versorgungsleitungen mit geringem Abstand zueinander zu verlegen, so dass sie in einfacher Weise mit einem gemeinsamen Anschlussflansch zur Befestigung der Anschlussplatten versehen werden können.In a further development of the invention, the connection points can the supply lines may be formed as a flange to which the connection plates can be attached in a simple manner. It is also advantageous the two supply lines with a small distance to each other relocate, allowing them in a simple way with a common connection flange be provided for fastening the connection plates can.

Dabei ergibt sich grundsätzlich die Möglichkeit, die Anschlussflansche nur einseitig an den Versorgungsrohren vorzusehen und auf der anderen Seite der Versorgungsrohre eine Verbindungslasche vorzusehen, so dass Schraubbolzen zum Anbringen der Anschlussplatten durch den Abstand der Versorgungsleitungen hindurchgeführt und in der Verbindungslasche verankert werden können.This basically gives the possibility of connecting flanges only on one side to provide the supply pipes and on the other Side of the supply pipes to provide a connection tab, so that bolt for attaching the terminal plates through the Distance of the supply lines passed and in the connecting strap can be anchored.

Möglich ist es aber auch, die Anschlussflansche beidseitig an den Versorgungsleitungen vorzusehen und mit je einem Anschlussgewinde für Schraubbolzen zum Anflanschen der Anschlussplatten zu versehen.But it is also possible, the connection flanges on both sides of the supply lines be provided and each with a connection thread for To provide bolt for flanging the connection plates.

In weiterer Ausgestaltung der Erfindung 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 a further embodiment of the invention, the connection plate can be fixed be connected with two spacer tubes, one of which with the Compressed air and the other with the coolant line in conjunction stands, wherein the spacer tubes terminate in a flange which firmly with a Nozzle housing is connectable, with two under a certain Angle to each other and to the axes of the spacer tubes standing Is provided with spray nozzles. These spray nozzles are in this case with a mixing chamber and with channels for compressed air and coolant flow connected. The connection plate also has through openings to the spacer tubes, which are sealed to the connection flanges abut the supply pipes.

Bei einer Variante kann aber auch vorgesehen werden, dass die Anschlussplatte selbst mit einer Mischkammer im Inneren versehen ist, die über Verbindungskanäle mit dem Druckluft- und mit dem Kühlflüssigkeitsanschluss verbunden ist und einen Ausgangsstutzen aufweist, der mit einem Anschlussleitungsstück zu einer Sprühdüse verbunden ist. Bei dieser Ausführungsform wird die Mischung von Kühlflüssigkeit und Druckluft daher innerhalb der Anschlussplatte vorgenommen und das Sprühgemisch wird dann zu der zugeordneten oder auch zu mehreren zugeordneten Sprühdüsen geliefert.In a variant but can also be provided that the connection plate itself is provided with a mixing chamber inside which via connection channels with the compressed air and with the coolant connection is connected and has an outlet nozzle, the connected to a connecting piece to a spray nozzle. at This embodiment is the mixture of cooling liquid and Compressed air therefore made within the connection plate and the Spray mixture is then added to or assigned to several supplied with spray nozzles.

Bei dieser Ausführungsform kann das Anschlussleitungsstück zu den Sprühdüsen gegenüber der Verlegungsebene der Versorgungsleitungen abgeknickt ausgeführt sein. Es kann auch lösbar am Ausgangsstutzen angesetzt und mit einer Verdrehsicherung versehen sein, 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 Abknicken von Leitungen einstellen müsste. Es wird dadurch auch möglich, mit einem identischen Anschlussstück mit einer Sprühdüse beide Sprühpositionen zu verwirklichen.In this embodiment, the connecting piece can be connected to the Spray nozzles opposite the laying level of the supply lines be executed bent. It can also be detachable at the outlet nozzle attached and provided with an anti-rotation device, which ensures that the connecting line pieces to the spray nozzles only in one be determined very specific position on the outlet nozzle can. This embodiment therefore provides the orientation of the spray safely, without an operator in a complex manner would have to adjust this spray angle by kinking lines. It also makes it possible with an identical connector to realize both spray positions with a spray nozzle.

Die Erfindung ist anhand von zwei Ausführungsbeispielen in der Zeichnung dargestellt und wird im folgenden erläutert. Es zeigen:

The invention is illustrated by two embodiments in the drawing and will be explained below. Show it:

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 supply pipes 1 and 2 each with square or even rectangular cross section with low Distance from each other in the longitudinal direction of the strand S and parallel to whose center plane 17 are laid, in the same way as based already explained in Fig. 3, in a rolling stand of a continuous casting plant is guided and shaped. The two supply lines 1 and 2, from one for compressed air supply and the other for cooling fluid or water supply, are arranged by at certain intervals Tabs 3 on one side and through the tabs 3 respectively opposite connection flanges 4 connected to each other and in each case on the side of the connection flanges 4 with openings 1a or 2a provided, via the compressed air or water respectively into appropriate Through openings of the flanges can occur.

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 flange 4 is in each case a connection plate in the form of a flange 5 of a spacer tube unit 6, consisting of two spacer tubes 7 and 8 and a further flange. 9 consists, in turn, with the help of screws 10 a nozzle housing 11 is flanged. This nozzle housing 11 is not shown in detail Way inside provided with a mixing chamber in the Compressed air and coolant from the spacer tubes 7 and 8 penetrates and mixed. The coolant / compressed air mixture will then be the two Spray nozzles 12 and 13 which are at an angle α to each other Aligned previously on the shape of the strand S together is tuned with the spray pattern of the spray jet 14.

Abgestimmt auf die Kühlanlage und das Walzgerüst wird auch jeweils die Länge der Distanzrohre 7 und 8.Tuned to the cooling system and the mill stand is also each the length of the spacer tubes 7 and 8.

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 will be readily apparent that in such an embodiment the spacer tube unit 6 is attached to the flange 4 in a simple manner and by means of a bolt 15 can be fixed by the flanges 4 and 5, through the gap between the supply pipes 1 and 2 and passed through the tab 3 therethrough. It is possible a precise alignment of the spacer tube unit 6 and thus also the spray nozzles 12 and 13 to ensure by dowel pins 16, the one allow exact alignment of the flanges 4 and 5 to each other.

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 necessary and that the maintenance of the nozzles 12, 13 is much easier, because for this purpose in a simple manner after loosening the pin 15, the entire distance unit 6 with the nozzle housing 1 can be removed without the supply lines 1, 2 would have to be dismantled. After restarting the Spacer tube unit, the spray nozzles 12, 13 again exactly aligned, without cumbersome setting operations are necessary. The Spray nozzles 12, 13 and their mouthpieces are on the nozzle housing 11th positively aligned, which also for the arrangement of the nozzle housing 11 to the spacer tube unit 6 and for the alignment of the spacer tube unit 6 to the supply lines 1 and 2 applies.

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 supply pipes 1 and 2 are parallel to each other and side by side and parallel to the median plane 17 of the strand S aligned. They are not here among each other, but arranged side by side in a horizontal installation level 25 and both on its top and on its underside with flanges 4 equipped, in turn, through their through holes the Establish connection to compressed air and coolant supply. On two flanges 4, the connection plates 18 are each attached, via each a spray nozzle 19 is supplied with a bent Connecting line piece 20 is provided. Inside the connection plate 18 is here in a manner not shown in each case a mixing chamber provided, in which compressed air and coolant mix and then via a connecting piece 21 and the connecting pipe piece 20 to the spray nozzles 19 are performed. Also in this case are the spray jets 14 tuned to the shape of the strand S, which also for the Buckling angle of the connecting line piece 20 applies. This connecting piece 20 is against rotation with the connecting piece 21 of Connection plate 18 connected and secured by a union nut, so that the connecting pipe piece 20 only in a very specific location can be attached to the connecting piece 21. The spray nozzle 19 can therefore only in either the position shown above or in the one shown below Be aligned, both positions by a 180 ° Twist the connection plates 18 come about. The connection plates 18 can also in this embodiment with a regulator 22 for controlling the compressed air / coolant ratio be provided.

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 allows easy and precise installation or disassembly in that the bolt 23, respectively the connection plate 18 holds on the flange 4, dissolved and the corresponding Spray nozzle unit removed, maintained and then re-set exactly becomes. The non-rotating connection between connecting pipe piece 20 and connecting piece 21 and their backup via a union nut 24 is known per se and is therefore not explained in detail.
