Abstract

Hitherto, only one roller carrier, which is connected to the supporting frame, has been used to support the metal strand emerging from the strip casting plant. However, it is a disadvantage here that, if required, the roller carrier can only be adjusted as a whole, i.e. as a complete unit, relative to the strand of cast metal and does not allow any adjustment and/or setting, in particular fine setting, in mutually separate zones relative to the cast strand. According to the invention, in contrast, adjustment and/or setting of the rollers of the roller carrier relative to the cast strand is possible in a simple manner in any desired zone by virtue of the fact that the roller carrier (3) is divided into a plurality of roller-carrying segments (5) which are connected to adjusting devices (6, 7, 8, 9, 10).

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Stützung eines Metallgießstranges, insbesondere zur Weichreduktion (sogenannte "softreduction"), d.h. zur sanften Querschnittsverminderung des Gießstranges bei einer Vorband-Gießanlage, bestehend aus einem unterhalb der Stranggießkokille, in einem feststehenden Rahmen angeordneten Rollenträger, dessen Rollen mit dem Gießstrang in Wirkverbindung stehen.The invention relates to a device for supporting a metal casting strand, in particular for soft reduction (so-called "soft reduction"), i.e. for gently reducing the cross-section of the casting strand in a pre-strip casting installation, consisting of a roller carrier arranged in a fixed frame below the continuous casting mold, the rollers of which are operatively connected to the casting strand.

Zur Stützung des aus der Vorband-Gießanlage austretenden Metall-Gießstranges hat man bisher nur Rollenträger benutzt, die mit dem Tragrahmen verbunden sind. Hierbei ist jedoch von Nachteil, daß der Rollenträger im Bedarfsfalle nur insgesamt, d.h. als ganzer gegen den Metallgießstrang verstellt werden kann und keine Verstellung und/oder Einstellung, insbesondere Feineinstellung in voneinander getrennten Bereichen gegen den Metallgießstrang ermöglicht.To support the metal casting strand emerging from the slab casting system, only roller carriers that have been connected to the supporting frame have been used so far. However, it is disadvantageous here that the roller carrier, if necessary, only as a whole, i.e. can be adjusted as a whole against the metal casting strand and does not allow any adjustment and / or adjustment, in particular fine adjustment against the metal casting strand in separate areas.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Stützung des Metallgießstranges, insbesondere zur Weichreduktion bei einer Vorband-Gießanlage zu schaffen, die in jedem beliebigen Bereich eine Verstellung und/oder Einstellung der Rollen des Rollenträgers gegen den Metallgießstrang ermöglicht.The object of the invention is to provide a device for supporting the metal casting strand, In particular to create soft reduction in a pre-cast caster, which allows adjustment and / or adjustment of the rollers of the roller carrier against the metal casting strand in any area.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Rollenträger in mehrere, rollentragende Segmente aufgeteilt ist, die mit Verstelleinrichtungen in Verbindung stehen. Mit Hilfe dieser Verstelleinrichtungen können sehr vorteilhaft sowohl einzelne Rollen oder auch mehrere Rollen gegen den Metallgießstrang verstellt werden, so daß in jedem beliebigen Bereich eine für den Metallgießstrang optimale Feineinstellung gewährleistet ist.This object is achieved in that the roller carrier is divided into several roller-bearing segments which are connected to adjusting devices. With the aid of these adjustment devices, both individual rollers or several rollers can be adjusted very advantageously against the metal casting strand, so that an optimal adjustment for the metal casting strand is ensured in any area.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus den nachfolgenden Erläuterungen eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels.Further details, features and advantages of the invention result from the following explanations of an exemplary embodiment shown schematically in the drawing.

Wie die Zeichnung zeigt, besteht die Vorrichtung zur Stützung des Gießstranges (1), insbesondere zur Weichreduktion bei einer Vorbandgießanlage aus einem unterhalb der Stranggießkokille (2) angeordneten Rollenträger (3). In der Zeichnung ist der Einfachheit halber nur ein Rollenträger dargestellt. Es ist jedoch verständlich, daß zur Stützung des Gießstranges (1) in der Praxis ein weiterer, dem Rollenträger (3) spiegelbildlich gegenüberliegender Rollenträger vorgesehen ist, die beide in einem feststehenden Rahmen (4) zueinander und/oder voneinander verstellbar angeordnet sind. Gemäß der Erfindung ist der Rollenträger (3) sehr vorteilhaft in mehrere Segmente (5) aufgeteilt, die mit Verstelleinrichtungen (6, 7, 8, 9, 10) in Wirkverbindung stehen. Die rollentragenden Segmente (5) sind hierbei aneinander gekoppelt, so daß jedes Segment für sich in einem beliebigen Winkel zum Gießstrang (1) verstellt und eingestellt werden kann. Zum allgemeinen Verstellen bzw. Einstellen des Rollenträgers (3) dient die obere in der Zeichnung dargestellte Verstelleinrichtung (6), an die über eine im Stützrahmen (4) angeordnete Mutter (11) geführte Spindel (12) gelenkbeweglich angreift, welche ihrerseits über ein Getriebe (13) mit einem Antriebsmotor (14) in Verbindung steht, während die im Stützrahmen (4) angeordneten Verstelleinrichtungen (7, 8, 9, 10) als überlastzylinder ausgebildet sind und zur Feineinstellung dienen. Als Verstelleinrichtungen zur Stützung des Gießstranges können sowohl mechanische, rein hydraulische oder auch mechanischhydraulisch ausgebildete Verstelleinrichtungen mit Vorteil eingesetzt werden.As the drawing shows, the device for supporting the casting strand (1), in particular for soft reduction in a preliminary casting line, consists of a roller carrier (3) arranged below the continuous casting mold (2). For the sake of simplicity, only one roller carrier is shown in the drawing. However, it is understandable that in practice a further roller support, which is opposite to the roller support (3), is provided to support the casting strand (1), both of which are adjustable in relation to and / or from each other in a fixed frame (4) are arranged. According to the invention, the roller carrier (3) is very advantageously divided into a number of segments (5) which are operatively connected to adjusting devices (6, 7, 8, 9, 10). The roller-bearing segments (5) are coupled to one another so that each segment can be adjusted and adjusted at any angle to the casting strand (1). For the general adjustment or adjustment of the roller carrier (3) is used the upper adjustment device (6) shown in the drawing, to which a spindle (12) guided in a support frame (4) arranged nut (11) engages in an articulated manner, which in turn engages via a gear (13) is connected to a drive motor (14), while the adjusting devices (7, 8, 9, 10) arranged in the support frame (4) are designed as overload cylinders and are used for fine adjustment. Mechanical, purely hydraulic or mechanical-hydraulic adjusting devices can advantageously be used as adjusting devices for supporting the casting strand.

Auf diese Weise können die Rollen (15) und/oder die Rollenträger bzw. die rollentragenden Segmente (5) auch einzeln für sich, und zwar verschieden weit und somit auch unterschiedlich stark gegen den Gießstrang (1) herangeführt und an diesen angedrückt werden. Dies ermöglicht eine optimale Stützung des Gießstranges (1), insbesondere Softreduktion der Vorband-Gießanlage, und zwar zum Trocken- als auch Naßgießen. Im übrigen sind im Stützrahmen (4), und zwar mit Abstand unter dem Rollenträger (3) in der Drehzahl stufenlos regelbar Reib- oder Transportrollen (16) angeordnet, die den Gießstrang (1) kontinuierlich nach unten ziehen.In this way, the rollers (15) and / or the roller carriers or the roller-bearing segments (5) can also be brought individually and individually, to different extents and thus to different degrees, against the casting strand (1) and pressed against them. This enables optimal support of the casting strand (1), in particular soft reduction of the pre-strip casting system, for both dry and wet casting. Otherwise, in the support frame (4), with a distance below the roller carrier (3) in the speed Infinitely variable friction or transport rollers (16) are arranged, which continuously pull the casting strand (1) downwards.
