Abstract
Description
Die Erfindung betrifft eine Einrichtung zum Wechseln eines Stützrollen-Segmentes der Strangführung einer Bogenstranggießmaschine für flüssige Metalle, insbesondere für flüssige Stahlwerkstoffe, mit einer den Wechselweg vom Betriebsort des jeweiligen Stützrollen-Segmentes in der Strangführung über einen Bogen bis zur Stranggießbühne bildenden Gleisführung, in deren paarweisen Schienen die Stützrollen-Segmente einzeln, an einer per Kran herausziehbaren oder absenkbaren Segmentwechselkette hängend, auf an den Stützrollen-Segmenten drehgelagerten Wechselrädern ausgebaut oder nach Wartung wieder eingebaut werden.The The invention relates to a device for changing a support roller segment the strand guide a bow casting machine for liquid metals, especially for liquid Steel materials, with a the change of the location of the respective Support rollers segment in the strand leadership over a Bow up to the continuous casting stage forming Track management, in their paired rails the support roller segments individually, on a segmental chain that can be pulled out or lowered by crane hanging, rotatably mounted on the support roller segments change gears removed or reinstalled after maintenance.
Eine
derartige Einrichtung zum Wechseln eines Stützrollen-Segmentes auf dem
bezeichneten Gebiet ist aus der
Der Erfindung liegt die Aufgabe zugrunde, durch die Geometrie der Wechselschienen und durch das Gewicht der Ausbaukette entstehende hohe Umlenkkräfte und die im oberen Seitenbereich des Stützrollen-Segmentes entstehenden Querkräfte aufzufan-gen bei gleichzeitiger Verminderung des Liefergewichtes des Stützrollen-Segmentes, so dass bei günstigerer Kräfteverteilung eine Ersparnis an Aufwand erzielt wird.Of the Invention is based on the object by the geometry of the exchange rails and by the weight of the expansion chain resulting high deflection forces and the resulting in the upper side region of the support roller segment transverse forces at the same time reduce the delivery weight the support roller segment, so that at cheaper force distribution a saving of effort is achieved.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass pro Stützrollen-Segment am Segmentrahmen nur ein Wechselradpaar angeordnet ist und dass das letzte, unterste Glied der Segmentwechselkette mit einem Paar dem Bogen der Schienenführung im Abstand angepasste Führungsrädern versehen ist. Die Vorteile sind eine Verringerung des Liefergewichtes bei den Stützrollen-Segmenten um mehrere Tonnen in einer Stranggießmaschine (und zwar bei der Hauptlieferung und zusätzlichen Wechselsegmenten), geringere Querkräfte im oberen Seitenbereich eines Stützrollen-Segmentes und der Wegfall von sonst üblichen Sicherungsbolzen an der Segmentwechselkette, die das Herumschwenken der letzten Lasche sichert.The Asked object is inventively achieved in that per support roller segment on the segment frame only one Wechselradpaar is arranged and that the last, lowest Link of the segment change chain with a pair of the rail guide in the Provided distance matched guide wheels is. The benefits include a reduction in delivery weight the support roller segments by several Tons in a continuous casting machine (for the main delivery and additional change segments), lower lateral forces in the upper side of a support roller segment and the omission of otherwise usual Locking bolts on the segment change chain, which pivot around the last tab secures.
In Ausgestaltung ist das Wechselradpaar im unteren Bereich des Segmentrahmens, jedoch ca. 100 bis 120 mm höher gegenüber der üblichen Anordnung angeordnet.In Design is the change gear pair in the lower part of the segment frame, however, about 100 to 120 mm higher across from the usual Arrangement arranged.
Die Kräfteaufnahme durch die Segmentwechselkette wird dadurch begünstigt, dass der Achsabstand des Führungsrad-Paares zum letzten, untersten Glied der Segmentwechselkette wesentlich geringer ist als der Achsabstand zwischen zwei anderen Segmentwechselketten-Gliedern.The forces recording by the segment change chain is favored by the fact that the center distance of the pair of guide wheels to the last, lowest member of the segment change chain much lower is the center distance between two other segment interchange links.
Als vorteilhaft für die praktische Ausführung hat sich erwiesen, dass der Achsabstand zwischen dem letzten, untersten Glied der Segmentwechselkette und dem Führungsrad-Paar ca. 50% der jeweiligen Achsabstände der übrigen Segmentwechsel-Ketten-glieder untereinander beträgt.When advantageous for has the practical design proved that the center distance between the last, lowest Link of the segment change chain and the pair of guide wheels approx. 50% of the respective center distances the rest Segment change chain links among each other.
Es ist jedoch auch eine Alternative zu beliebigen Wechselschienengeometrien, dass der Achsabstand des Führungsrad-Paares zum letzten, untersten Glied der Segmentwechselkette auf die jeweilige Wechselschienengeometrie abgestimmt ist.It however, it is also an alternative to any exchange rail geometry, that the axial distance of the pair of guide wheels to the last, lowest member of the segment change chain to the respective Change rail geometry is tuned.
