Zum Stand der Technik zählen noch feste Verrohrungen. So ist aus der DE 38 26 019
eine Profiliermaschine bekannt, deren Zu- und Ablauf aus festen Rohren besteht, die
mit in den Umformrollen vorgesehenen Kammern verbunden sind. Ein einfaches Lösen
der Medienzufuhr und Abführleitungen ist hier nicht erkennbar.
Ferner ist aus der DE 33 15 376 C1 eine Stranggießrolle bekannt, bei der der
Tragzapfen über ein Anschlussstück mit der Verrohrung verbunden ist. Einzelheiten
des Anschlussstückes ergeben sich hieraus nicht.Fixed piping still belongs to the state of the art. A profiling machine is known from DE 38 26 019, the inlet and outlet of which consist of solid tubes which are connected to chambers provided in the forming rollers. A simple disconnection of the media supply and discharge lines cannot be seen here.
Furthermore, a continuous casting roller is known from
Der Erfindung liegt die Aufgabe zugrunde, eine Strangführungseinrichtung zum Erzeugen von Metallsträngen, insbesondere aus Stahl, zu schaffen, bei der mit einfachen konstruktiven Mitteln eine wartungsarme, leckagefreie Verbindung zwischen den Rollen und der Kühlmedienversorgungseinrichtung vorhanden ist, die vor Ort leicht lös- und wieder verbindbar und übersichtlich zuordnenbar ist. The invention has for its object to provide a strand guide Generate strands of metal, especially steel, to create with simple constructional means a low-maintenance, leak-free connection between the roles and the coolant supply facility is present that easily on site is detachable and connectable and clearly assignable.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des
Anspruchs 1 bzw. des Anspruchs 2 gelöst. Die weiteren Ansprüche stellen eine vorteilhafte Weiterbildung der
Erfindung dar.
Erfindungsgemäß werden als Verbindungsleitungen Rohre vorgeschlagen, die
einenends an die Kühlmedienversorgungseinrichtung angeschlossen sind und
anderenends mit einer Dichtung in Verbindung stehen, die leckagefrei eine achsiale
und laterale Bewegung zwischen Rohrende und Hülse zuläßt. Zur Aufnahme der
lateralen Bewegung, die eine Winkelabweichung zwischen Hülse und
Verbindungsleitung bis zu 10° zuläßt, ist jeweils das eingesteckte Bauteil mit einem
Wulst versehen. Die kugelförmige Kontur des Wulstes steht dabei mit einer Dichtung in
Verbindung.This object is achieved according to the invention by the features of claim 1 and claim 2. The further claims represent an advantageous development of the invention.
According to the invention, pipes are proposed as connecting lines, which are connected at one end to the cooling medium supply device and at the other end are connected to a seal which allows an axial and lateral movement between the pipe end and the sleeve without leakage. To accommodate the lateral movement, which allows an angular deviation between the sleeve and the connecting line of up to 10 °, the inserted component is provided with a bead. The spherical contour of the bead is connected to a seal.
Diese Dichtung ist einmal aus einem duktilem Material aufgebaut, wobei das Dichtungsmaterial entweder in eine Nut eingelegt ist, die in dem Wulst oder dem den Wulst umhüllenden Bauteil eingelassen ist. Die Dichtung hat dabei eine Länge, die mindestens der Bogenlänge der lateralen Bewegung bzw. der Länge der achsialen Bewegung entspricht.This seal is made of a ductile material, which Sealing material is either inserted into a groove in the bead or the Bead enveloping component is embedded. The seal has a length that at least the arc length of the lateral movement or the length of the axial Movement corresponds.
In dieser Ausgestaltung ist die Dichtung aus Kunststoff oder Gummi. Dabei ist die dichtungsaktive Wandung bezüglich des Durchmessers so ausgestaltet, daß der Wulst eingeklemmt wird. Darüber hinaus wird der Bereich der aus duktilem Material aufgebauten Dichtung, der mit dem Medium in Kontakt steht, durch dessen Druck so verformt, daß der den Wulst kontaktierende Teil der Dichtung intensiv gegen diese gedrückt wird.In this embodiment, the seal is made of plastic or rubber. Here is the seal-active wall in terms of diameter designed so that the bead is pinched. In addition, the area is made of ductile material constructed seal, which is in contact with the medium, by the pressure so deformed that the part of the seal contacting the bead intensely against this is pressed.
Erfindungsgemäß kann der Wulst an der Hülse oder auch an dem Rohr der Verbindungsleitung vorgesehen sein. Aus Instandhaltungsgründen wird das Verschleißteil, hier die Dichtung, in dem leichter zu demontierenden Bauteil vorgesehen.According to the bead on the sleeve or on the tube of the Connection line may be provided. For maintenance reasons it will Wearing part, here the seal, in the component that is easier to disassemble intended.
Die Dichtung ist weiterhin als dünnwandige metallische Dichthülse aufgebaut. Diese Dichthülse ist so angeordnet, daß sie kopfendig befestigt ist und daß ihr Durchmesser ohne Behinderungen durch das sie aufnehmende Bauteil vergrößerbar ist.The seal is also constructed as a thin-walled metallic sealing sleeve. This Sealing sleeve is arranged so that it is attached at the head and that its diameter can be enlarged without hindrance by the component receiving it.
Die Verbindungsleitungen können dabei mit und ohne Wulst versehen sein, und an
Stelle der lösbaren Verbindung die laterale und achsiale Bewegung über einen
Kompensator aufnehmen.
Von der Erfindung umfaßt ist auch die Ausgestaltung, daß sowohl die Hülse wie die
Rohre der Verbindungsleitungen geradwandig ausgestaltet sind, also ohne einen
kopfendig vorgesehenen Wulst. Die hier vorgesehenen Dichtungen umgreifen
großflächig das Ende des jeweils umhüllten Bauteils, die Hülse oder das Rohrende.
Die Dichtung ist dabei so ausgestaltet, daß jeweils zwischen dem von der Dichtung
umfaßten Bauteil und dem die Dichtung umhüllenden Bauteil (Rohr oder Hülse) eine
Kammer angeordnet ist, in die das unter Druck stehende Kühlmedium, regelmäßig
Wasser, eindringt. Während des Betriebes unterstützt der Druck des eingesetzten
Mediums das Anpressen der Dichtung gegen das von ihr umfaßte Bauteil und sorgt für
eine leckagefreie Verbindung.The connecting lines can be provided with and without a bulge and, instead of the detachable connection, absorb the lateral and axial movement via a compensator.
The invention also encompasses the configuration that both the sleeve and the pipes of the connecting lines are designed to be straight-walled, that is to say without a bead provided at the head. The seals provided here encompass a large area around the end of the encased component, the sleeve or the pipe end. The seal is designed such that a chamber is arranged between the component encompassed by the seal and the component enveloping the seal (tube or sleeve) into which the pressurized cooling medium, regularly water, penetrates. During operation, the pressure of the medium used supports the pressing of the seal against the component it encompasses and ensures a leak-free connection.
Die laterale Bewegung beider Bauteile gegeneinander wird durch die Form oder durch die hierfür vorgesehene elastische Dichtmasse ermöglicht.The lateral movement of both components against each other is determined by the shape or by the elastic sealing compound provided for this purpose.
Als Material für das Dichtelement kommen Gummi oder Kunststoff wie auch eine dünnwandige metallische Hülse zum Einsatz. Die aus elastischem Material gefertigte Hülse ist mindestens an der Innenseite im Bereich der Mündung des größeren und damit das andere Bauteil umhüllenden Bauteil, entweder im Rohr oder der Hülse, fest verbunden, das andere Ende ist offen oder läßt durch Öffnungen den Zutritt des den Druck beaufschlagten Mediums in die Kammer zu.The material for the sealing element is rubber or plastic as well as one thin-walled metallic sleeve for use. The one made of elastic material Sleeve is at least on the inside in the area of the mouth of the larger and so that the other component enveloping component, either in the tube or the sleeve, firmly connected, the other end is open or allows access through the openings Pressurized medium into the chamber.
Durch letztgenannten Aufbau können kostengünstigst Normbauteile eingesetzt werden, die ohne weitere Bearbeitung, d.h. nur auf Länge zugeschnitten, zum Einsatz kommen.Due to the latter structure, standard components can be used at low cost without further processing, i.e. only cut to length, for use come.
