Abstract
Description
Die Erfindung betrifft eine Stahlstranggießanlage, wobei eine bogenförmigen Kokille und ein erster Teil der'Stfangführung in einem Gestell eingebaut sind, das auf einer Traverse auswechselbar angeordnet ist und nachgeordnete Rollenführungselemente tragende Strangführungsrahmen mittels senkrecht zum Radiusstrahl des Strangführungsbogens verlaufender Gleitführungen an der Unterseite der Traverse angebracht sind.The invention relates to a continuous steel casting machine, wherein an arcuate mold and a first part of the 'rod guide are installed in a frame which is interchangeably arranged on a cross member and downstream guide rails carrying roller guide elements are attached to the underside of the cross member by means of sliding guides which run perpendicular to the radius beam of the strand guide bend .
Bei einer bekannten Stranggießanlage ist auf einem Hallengerüst ein auswechselbares Gestell lösbar angeordnet, in dem die Kokille mit ihren Führungs- und Oszillationselementen sowie ein erster Teil der Rollenführung aufgenommen sind. Diese Anordnung soll ein schnelles Auswechseln dieser Anlagenteile und deren schnelle Ausrichtung auf die nachgeordneten Teile der Stützrollenführung ermöglichen. (DE-OS 1 957 689).In a known continuous caster, an exchangeable frame is detachably arranged on a hall frame, in which the mold with its guide and oscillation elements and a first part of the roller guide are accommodated. This arrangement is intended to quickly replace these system parts and align them quickly with the downstream parts enable the support roller guide. (DE-OS 1 957 689).
Zum Stand der Technik gehört weiter eine Stranggießanlage mit einem die Kokille, deren Oszillationsvorrichtung sowie den ersten Abschnitt der Strangführung aufnehmenden Wechselgestell auf einer Traverse lösbar angeordnet ist, die über einen oberen Teil eines Strangführungsrahmens und zusätzliche Stützwangen mit einem hochgezogenen Fundament verbunden ist. Durch diese Anordnung sollen thermisch bedingte radiale Versetzubewegungen zwischen dem ersten Teil und den folgenden Teilen der Strangführung und andere Abweichungen der Führungselemente vom vorbestimmten Kreisbogen der Strangführung vermieden werden. (DE-OS 29 10 547).The prior art also includes a continuous casting plant with a mold, the oscillation device and the first section of the strand guide, which is detachably arranged on a crossbar, which is connected to an elevated foundation via an upper part of a strand guide frame and additional support cheeks. This arrangement is intended to avoid thermally induced radial displacement movements between the first part and the following parts of the strand guide and other deviations of the guide elements from the predetermined circular arc of the strand guide. (DE-OS 29 10 547).
Aufgabe der Erfindung ist die Schaffung einer Stahlstranggießanlage mit einer konstruktiv einfachen,spiel-, schwingungs-und versatzfreien Verbindung von Wechselgestell und nachgeordneter Rollenführung, wobei die Gefahr eines Strangdurchbruchs und einer Überlastung der Strangführungsrollen verringert ist und die Strangführungselemente sowohl in Richtung der Strangachse als auch seitlich und radial zum Strangführungsbogen auswechselbar sind.The object of the invention is to provide a continuous steel casting installation with a structurally simple, play-free, vibration-free and offset-free connection of the interchangeable frame and subsequent roller guide, the risk of strand breakdown and overloading of the strand guide rollers being reduced and the strand guide elements both in the direction of the strand axis and laterally and are exchangeable radially to the strand guide bend.
Die gestellte Aufgabe wird nach der Erfindung dadurch gelöst, daß die an der Außenseite des Strangführungsbogens am Fundament verankerte Traverse mit einem gabelartigen Teil den ersten Teil der Strangführung umgibt und das erste nachfolgende Strangführungselement mit einer Seite an der entsprechend dem Radiusstrahl des Strangführungsbogens verlaufenden Unterseite der Traverse geführt ist.The object is achieved according to the invention in that the cross member anchored on the outside of the strand guide arch on the foundation surrounds the first part of the strand guide with a fork-like part and the first subsequent strand guide element with one side on the underside of the cross member running in accordance with the radius beam of the strand guide arch is led.
Auf diese Weise wird eine einfache, besonders starre und spielfreie Anordnung des Wechselgestells erreicht, wobei Versetzbewegungen zwischen dem Wechselgestell und der nachgeordneten Strangführung vermieden werden. Die Gefahr von Strangdurchbrüchen und überlastung von Strangführungsrollen wird vermindert. Die neue Bauweise ermöglicht einen Aus-und Einbau der am Strangführungsrahmen angeordneten Strangführungselemente entweder nach oben durch die Gabelöffnung der Traverse oder in seitlicher Richtung. Im Störungsfall sind Strangführungsrollen und Sprühkühlung der Strangführungselemente besonders gut zugänglich.In this way, a simple, particularly rigid and play-free arrangement of the interchangeable frame is achieved, offset movements between the interchangeable frame and the downstream strand guide being avoided. The risk of strand breaks and overloading of strand guide rollers is reduced. The new design enables the strand guide elements arranged on the strand guide frame to be removed and installed either upwards through the fork opening of the crossmember or in the lateral direction. In the event of a fault, strand guide rollers and spray cooling of the strand guide elements are particularly accessible.
Gemäß einem weiteren Merkmal der Erfindung reicht der im Wechselgerüst aufgenommene erste Teil der Strangführung etwa bis zur Unterseite der Traverse. Dadurch wird die Zugänglichkeit der nachfolgenden Strangführungselemente weiter verbessert.According to a further feature of the invention, the first part of the strand guide accommodated in the interchangeable frame extends approximately to the underside of the traverse. This further improves the accessibility of the subsequent strand guide elements.
Das Wechselgerüst kann vorteilhaft aus einer Grundplatte bestehen, die im Bereich der Strangführung gabelartig gestaltet ist und an ihrer Oberseite Lagerböcke für Führungslenker und seitlich der Strangführung gelagerte, mit Drehantrieb versehene Hubexzenter als Oszillationseinrichtung der Kokille trägt.The interchangeable stand can advantageously consist of a base plate, which is designed in a fork-like manner in the area of the strand guide and carries on its upper side bearing blocks for guide links and a lifting eccentric mounted on the side of the strand guide and provided with a rotary drive as an oscillating device for the mold.
Eine besonders steife und schwingungsfreie Konstruktion kann dadurch erreicht werden, daß die Gleitführungsverbindung zwischen Traverse und Strangführungsrahmen in einer Fundamentnische angeordnet sind. Die Fundamentnische gestattet den Zugang zum ersten Strangführungselement.A particularly rigid and vibration-free construction can be achieved in that the sliding guide connection between the cross member and the strand guide frame are arranged in a foundation niche. The foundation niche allows access to the first strand guide element.
Ein weiterer Vorteil wird nach der Erfindung darin gesehen, daß eine Führung für das der Traverse unmittelbar nachgeordnete Strangführungselement an der Unterseite der Traverse in Richtung des Radiusstrahles R verstellbar angeordnet ist.A further advantage is seen according to the invention in that a guide for the strand guide element immediately downstream of the cross member is arranged on the underside of the cross member in the direction of the radius beam R so as to be adjustable.
Auf diese Weise kann das der Traverse unmittelbar nachgeordnete Strangführungselement auf den ersten Abschnitt der Strangführung bei der Montage ausgerichtet und später bei Bedarf nachgestellt werden.In this way, the strand guide element immediately downstream of the cross member can be aligned with the first section of the strand guide during assembly and readjusted later if required.
In der Zeichnung ist ein Ausführungsbeispiel der Erfinung dargestellt. Sie zeigt in Seitenansicht den oberen Teil einer Stahlstranggießanlage mit bogenförmiger Strangführung.In the drawing, an embodiment of the invention is shown.

Die Traverse 2 überbrückt eine Nische 4 im Fundamentsockel 1 und kragt mit einem gabelartigen Teil 5 bis in den Strangführungsbereich vor. Die Unterseite des gabelartigen Teils 5 der Traverse 2 verläuft etwa entsprechend dem Radiusstrahl R des Strangführungsbogens.On the
Eine im Strangführungsbereich gabelartig ausgebildete Grundplatte 6 eines Wechselgestells ist mit Schrauben 7 auf der Traverse 2 befestigt. Auf der Grundplatte 6 sind zwei Lagerböcke 8 angeordnet, an denen obere und untere Lenker 9, 10 gelagert sind, die andererseits an u-förmigen Kokillensätteln 11 angelenkt sind. Eine Kokille 12 wird von den beiden Kokillensätteln 11 gehalten. Ein Gießrohr 13 eines Gießbehälters 14 ragt in das Innere der Kokille 12.A
Als Oszillationsantrieb der Kokille 12 sind unterhalb der Kokillensättel 11 auf der Grundplatte 6 von Wellen 15 angetriebene Hubexzenter 16 gelagert. Auf den Hubexzentern 16 sind an den Kokillensätteln 11 angelenkte Pleuel 18 geführt.As the oscillation drive of the
An den Kokillensätteln 11 sind Rollen 19 gelagert, an denen ein mit Stützrollen 20 versehener erster Teil 21 der Strangführung mittels Kulissenführungen 22 an seiner Oberseite abgestützt ist. Der erste Teil 21 der Strangführung ist im unteren Bereich mit Bolzen 23 versehen, die in an der Grundplatte 6 angebrachten Taschen 24 abgestützt sind.
Innerhalb der Fundamentnische 4 sind in an der Unterseite der Traverse 2 angebrachten Kulissenführungen 25 zwei parallel zueinander verlaufende Strangführungsrahmen 26 mittels Kulissensteinen 27 und Verbindungsbolzen 28 geführt. Die Kulissenführungen 25 sind etwa senkrecht zu dem zwischen der Traverse 2 und einem ersten Strangführungselement 29 verlaufenden Radiusstrahl R des Strangführungsbogens ausgerichtet. Auf diese Weise können Dehnungen der Strangführungsrahmen 26 sich nur in Richtung der Strangachse auf das erste Strangführungselement 29 auswirken.Within the
Die Strangführungselemente 29, 30 sind mittels Führungen 31 an den Strangführungsrahmen 26 verschiebbar angeordnet. Das erste Strangführungselement 29 ist an einer Seite an einer an der Unterseite der Traverse 2 angebrachten Führung 32 verschiebbar abgestützt. Auch durch diese Anordnung der Führung 32 wird ein Versetzen des ersten Strangführungselementes 29 und damit seiner Stützrollen 33 gegenüber den Stützrollen 20 des ersten Teils 21 der Strangführung vermieden. Die Führung 32 ist in Richtung des Radiusstrahles R verstellbar.The
