Description

Strangführungssegment und Stranggießanlage  Strand guide segment and continuous casting plant
Die vorliegende Erfindung betrifft ein Strangführungssegment für eine Stranggießanlage nach Gattung des unabhängigen Anspruchs 1 . Gegenstand der Erfindung ist auch eine Stranggießanlage gemäß Anspruch 10. The present invention relates to a strand guide segment for a continuous casting plant according to the preamble of the independent claim 1. The invention also relates to a continuous casting plant according to claim 10.
Stand der Technik In heutigen Stranggießanlagen für Metalle, insbesondere Stahlwerkstoffe, wird das flüssige Metall zunächst in eine Kokille eingebracht und anschließend als Strang in teilerstarrter Form durch eine Strangführung, auch Stützrollengerüst genannt, mit Rollen geführt. Aus der DE 19 63 146 C1 ist es bekannt, Teile des Stützrollengerüstes für mehrere Rollen zu Strangführungssegmenten zusammenzufassen, wobei jedes Strangführungssegment einen Oberrahmen und einen diesem gegenüberliegenden Unterrahmen aufweist, welche strangführende Rollen tragen, und deren Abstand zueinander über Zuganker und Distanzstücke auf das Gießformat einstellbar ist. Der Oberrahmen und der Unterrahmen eines jeweiligen Strangführungssegments werden durch vier an den äußeren Ecken außerhalb der Strangbahn angeordnete, den Oberrahmen und den Unterrahmen miteinander verbindende Hydraulikzylindereinheiten gegeneinander geklemmt. Aus der WO 2006/050868 A1 ist eine Strangführung mit Strangführungssegmenten bekannt, bei denen der jeweilige Oberrahmen und Unterrahmen über Hydraulikzylindereinheiten miteinander verbunden und gegeneinander geregelt anstellbar sind. Die Hydraulikzylindereinheiten sind an dem Oberrahmen und dem Unterrahmen gelagert montiert. Zu Wartungszwecken an derartigen Strangführungssegmenten müssen der Oberrahmen und der Unterrahmen voneinander getrennt bzw. entkoppelt werden. Dazu müssen die jeweiligen Lagerungen der Hydraulikzylindereinheiten an dem Oberrahmen oder dem Unterrahmen geöffnet werden. Damit eine derartige Lagerung einfach geöffnet werden kann, muss für diese ein ausreichend großes Spiel vorgesehen sein. Eine derartige Realisierung wirkt sich aber nachteilig auf die Genauigkeit der durch das Strangführungssegment eingestellten Strangdicke aus. Daher können große Abweichungen zwischen der durch das Strangführungssegment tatsächlich eingestellten Strangdicke und der Sollstrangdicke auftreten. PRIOR ART In today's continuous casting plants for metals, in particular steel materials, the liquid metal is first introduced into a mold and then passed as a strand in teilerstarrter form by a strand guide, also called support roll stand, with rollers. From DE 19 63 146 C1 it is known to combine parts of the support roller frame for several roles to strand guide segments, each strand guide segment has an upper frame and a subframe opposite this, which carry strand-guiding roles, and their distance from each other via tie rods and spacers adjustable to the casting format is. The upper frame and the lower frame of each strand guide segment are clamped against each other by four hydraulic cylinder units arranged at the outer corners outside the strand path, connecting the upper frame and the lower frame with each other. From WO 2006/050868 A1, a strand guide with strand guide segments is known, in which the respective upper frame and subframe are connected to one another via hydraulic cylinder units and can be adjusted in relation to one another. The hydraulic cylinder units are mounted mounted on the upper frame and the subframe. For maintenance purposes on such strand guide segments, the upper frame and the lower frame must be separated from each other or decoupled. For this purpose, the respective bearings of the hydraulic cylinder units on the upper frame or the subframe must be opened. For such a storage can be opened easily, a sufficiently large game must be provided for this. Such a realization, however, adversely affects the accuracy of the strand thickness set by the strand guide segment. Therefore, large deviations may occur between the strand thickness actually set by the strand guide segment and the target strand thickness.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Strangführungssegment für eine Stranggießanlage bereitzustellen, das eine einfache Wartung und zugleich im Vergleich zum Stand der Technik eine größere Genauigkeit der durch das Strangführungssegment eingestellten Strangdicke gewährleistet. Außerdem soll die vorliegende Erfindung eine Stranggießanlage bereitzustellen, die einfach gewartet werden kann und eine hohe Genauigkeit der durch ihre Strangführungssegmente jeweils eingestellten Strangdicke gewährleistet. The present invention is therefore an object of the invention to provide a strand guide segment for a continuous casting, which ensures easy maintenance and at the same time compared to the prior art, a greater accuracy of the set by the strand guide segment strand thickness. In addition, the present invention to provide a continuous casting, which can be easily maintained and ensures high accuracy of each set by their strand guide segments strand thickness.
Die Aufgabe der vorliegenden Erfindung wird durch ein Strangführungssegment mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Merkmalen der abhängigen Ansprüche, die beliebig kombiniert werden können. The object of the present invention is achieved by a strand guide segment having the features of claim 1. Advantageous developments emerge from the features of the dependent claims, which can be combined as desired.
Das vorgestellte Strangführungssegment für eine Stranggießanlage für Metalle, insbesondere Stahlwerkstoffe, weist einen Oberrahmen und einen Unterrahmen auf, die während eines Gießbetriebs der Stranggießanlage über positionsgeregelte Hydraulikzylindereinheiten miteinander verbunden sind. Die Hydraulikzylindereinheiten sind angeordnet und ausgebildet zum Einstellen eines Abstands zwischen dem Oberrahmen und dem Unterrahmen, wobei der eingestellte Abstand eine Strangdicke eines durch das Strangführungssegment zu führenden Strangs vorgibt bzw. einstellt. Jede Hydraulikzylindereinheit weist eine Kolbenstange auf, die mittels eines aufgebrachten Hydraulikdrucks positionsgeregelt ausfahrbar bzw. einfahrbar ist, um den Abstand zwischen dem Oberrahmen und dem Unterrahmen zu vergrößern bzw. zu verkleinern. Bevorzugt weist das vorgestellte Strangführungssegment zwei Paare von Hydraulikzylindereinheiten auf, die beidseitig und außerhalb der Strangbahn des Strangführungssegments angeordnet sind. Bevorzugt hat das Strangführungssegment auf beiden Seiten der Strangbahn jeweils einen Seitenrahmen, die eine geführte Bewegung des Oberrahmens und des Unterrahmens relativ zueinander in Reaktion auf Auslenkungen bzw. Längenänderungen der Hydraulikzylindereinheiten zulassen. Ein erstes Ende jeder der Hydraulikzylindereinheiten ist an dem Oberrahmen gelagert. Ferner ist jede der Hydraulikzylindereinheiten, konkret ihre Kolbenstange, an ihrem von dem Oberrahmen abgewandten, zweiten Ende mittels einer jeweiligen Flanschvorrichtung mit einer jeweiligen Zugstange lösbar verbunden. Die Zugstangen sind an ihrem von der Flanschvorrichtung abgewandten Ende an dem Unterrahmen gelagert. Jede Hydraulikzylindereinheit, genauer genommen deren Kolbenstange, ist bevorzugt mittels der jeweiligen Flanschvorrichtung starr mit der jeweiligen Zugstange verbunden. Durch eine Positionsregelung bewirkte Längenänderungen der an dem Oberrahmen gelagerten Hydraulikzylindereinheiten werden über die an dem Unterrahmen gelagerten Zugstangen in eine entsprechende Veränderung des Abstands zwischen dem Oberrahmen und dem Unterrahmen umgesetzt. Die Zugstangen sind bevorzugt nicht längenveränderbar ausgestaltet. The presented strand guide segment for a continuous casting plant for metals, in particular steel materials, has an upper frame and a lower frame which are connected to one another during a casting operation of the continuous casting plant via position-controlled hydraulic cylinder units. The Hydraulic cylinder units are arranged and configured to set a distance between the upper frame and the subframe, the set distance prescribing a strand thickness of a strand to be led through the strand guide segment. Each hydraulic cylinder unit has a piston rod which can be extended or retracted in a positionally regulated manner by means of an applied hydraulic pressure in order to increase or decrease the distance between the upper frame and the lower frame. Preferably, the presented strand guide segment on two pairs of hydraulic cylinder units, which are arranged on both sides and outside the strand web of the strand guide segment. Preferably, the strand guide segment on each side of the strand web has a respective side frame which permits guided movement of the upper frame and the lower frame relative to one another in response to deflections or changes in length of the hydraulic cylinder units. A first end of each of the hydraulic cylinder units is supported on the upper frame. Furthermore, each of the hydraulic cylinder units, specifically their piston rod, at their remote from the upper frame, the second end by means of a respective Flanschvorrichtung with a respective tie rod releasably connected. The tie rods are mounted on their side remote from the flange device end to the subframe. Each hydraulic cylinder unit, more precisely its piston rod, is preferably rigidly connected to the respective pull rod by means of the respective flange device. Positional control of changes in the length of the hydraulic cylinder units mounted on the upper frame are converted into a corresponding change in the distance between the upper frame and the lower frame via the tie rods mounted on the lower frame. The tie rods are preferably not configured variable in length.
Die Bereitstellung der Flanschvorrichtungen, über die eine jeweilige Hydraulikzylindereinheit bzw. deren Kolbenstange mit einer jeweiligen Zugstange lösbar verbunden ist, ermöglicht eine einfache Trennung von Oberrrahmen und Unterrahmen, ohne dass die Lagerungen der Hydraulikzylindereinheiten am Oberrahmen geöffnet werden müssen. Somit brauchen die Lagerungen der Hydraulikzylindereinheiten nicht mit einem großen Spiel versehen sein. Die Lagerungen sind daher spielarm ausgestaltbar, wodurch das vorgestellte Strangführungssegment eine hohe Präzision der eingestellten Strangdicke gewährleistet. The provision of the flange devices, via which a respective hydraulic cylinder unit or its piston rod is releasably connected to a respective pull rod, allows easy separation of Oberrrahmen and Subframe without having to open the bearings of the hydraulic cylinder units on the upper frame. Thus, the bearings of the hydraulic cylinder units need not be provided with a great deal of play. The bearings are therefore playfully ausgestaltetbar, whereby the presented strand guide segment ensures high precision of the set strand thickness.
In einer Weiterbildung des vorgestellten Strangführungssegments ist vorgesehen, dass die Hydraulikzylindereinheiten, insbesondere deren Kolbenstangen, mit den jeweiligen Zugstangen über die jeweiligen Flanschvorrichtungen verschraubt sind. Durch die Verschraubungen werden ein einfaches Lösen der Hydraulikzylindervorrichtungen von den Zugstangen, gleichbedeutend mit einem einfachen Trennen des Oberrahmens von dem Unterrahmen, während der Wartung und zugleich eine sehr zugfeste Verbindung zwischen den Hydraulikzylindervorrichtungen und den Zugstangen während des Gießbetriebs ermöglicht. In a development of the presented strand guide segment, it is provided that the hydraulic cylinder units, in particular their piston rods, are screwed to the respective tie rods via the respective flange devices. The fittings allow easy release of the hydraulic cylinder devices from the tie rods, equivalent to simply separating the upper frame from the subframe, during maintenance, and at the same time providing a very tight connection between the hydraulic cylinder devices and the tie rods during the casting operation.

Zudem ist in einer Weiterbildung des vorgestellten Strangführungssegments vorgesehen, dass die Hydraulikzylindereinheiten mit der jeweiligen Flanschvorrichtung lösbar verbunden sind. Ist eine jeweilige Flanschverbindung sowohl mit der jeweiligen Zugstange als auch mit der jeweiligen Hydraulikzylindereinheit lösbar verbunden, so kann die Flanschverbindung besonders einfach bei Wartungsarbeiten ausgebaut und auf Verschleiss geprüft werden. Es kann auch vorgesehen sein, dass die jeweilige Flanschvorrichtung thermisch auf die jeweilige Hydraulikzylindereinheit, insbesondere auf deren Kolbenstange, aufgeschrumpft worden ist, und diese Flanschvorrichtung mit der jeweiligen Zugstange verschraubt ist. Es kann aber auch vorgesehen sein, dass die Flanschvorrichtung mit einer aus der Gruppe der Hydraulikzylindereinheit und der Zugstange fest verbunden ist, und die Flanschvorrichtung mit der anderen der Gruppe der Hydraulikzylindereinheit und der Zugstange lösbar verbunden, insbesondere verschraubt, ist. In a development of the presented strand guide segment is provided that the tie rods are releasably connected with their respective flange device. In addition, it is provided in a development of the presented strand guide segment, that the hydraulic cylinder units are detachably connected to the respective flange device. If a respective flange connection is detachably connected both to the respective pull rod and to the respective hydraulic cylinder unit, then the flange connection can be removed particularly easily during maintenance work and checked for wear. It can also be provided that the respective flange device has been thermally shrunk onto the respective hydraulic cylinder unit, in particular on its piston rod, and this flange device is screwed to the respective pull rod. But it can also be provided that the flange is firmly connected to one of the group of hydraulic cylinder unit and the pull rod, and the flange device with the other of the Group of hydraulic cylinder unit and the pull rod releasably connected, in particular screwed, is.
In einer Weiterbildung des vorgestellten Strangführungssegments ist vorgesehen, dass die Hydraulikzylindereinheiten an dem Oberrahmen mittels Gelenklagern auf Bolzen gelagert sind. Dadurch wird eine besonders spielarme Lagerung der Hydraulikzylindereinheiten realisiert, so dass das vorgestellte Strangführungssegment aufgrund der spielarmen Anbindung des Oberrahmens an den Unterrahmen eine hohe Präzision der eingestellten Strangdicke gewährleistet. In a further development of the presented strand guide segment is provided that the hydraulic cylinder units are mounted on the upper frame by means of spherical bearings on bolts. As a result, a particularly low-play storage of hydraulic cylinder units is realized, so that the presented strand guide segment ensures high precision of the set strand thickness due to the low-play connection of the upper frame to the subframe.
In einer Weiterbildung des vorgestellten Strangführungssegments ist vorgesehen, dass die Zugstangen an dem Unterrahmen mittels Gelenklagern auf Bolzen gelagert sind.

Bevorzugt werden sowohl die Hydraulikzylindereinheiten als auch die Zugstangen an ihrem zugeordneten Rahmen mittels Gelenklagern auf Bolzen gelagert. Dadurch gewährleistet das vorgestellte Strangführungssegment eine besonders hohe Präzision der eingestellten Strangdicke. Preferably, both the hydraulic cylinder units and the tie rods are mounted on their associated frame by means of spherical bearings on bolts. As a result, the presented strand guide segment ensures a particularly high precision of the set strand thickness.
Ferner ist in Weiterbildungen des vorgestellten Strangführungssegments vorgesehen, dass die Hydraulikzylindereinheiten und/oder die Zugstangen jeweils mit geteilten Lagerschalen und einem geteilten Lagerblock in ihrem zugeordneten Rahmen geklemmt sind. Dadurch wird eine spielarme Anbindung des Oberrahmens an den Unterrahmen erreicht, so dass das vorgestellte Strangführungssegment eine hohe Präzision der eingestellten Strangdicke ermöglicht. Zugleich können die Hydraulikzylindereinheiten und/oder die Zugstangen zu Wartungs- und Reparaturzwecken ohne großen technischen Aufwand von dem Oberrahmen bzw. Unterrahmen gelöst werden. In einer Weiterbildung des vorgestellten Strangführungssegments ist zudem vorgesehen, dass die Hydraulikzylindereinheiten an ihrem ersten Ende jeweils einen Lagerblock aufweisen, beispielsweise in der Form, dass das erste Ende einer jeweiligen Hydraulikzylindereinheit als ein Lagerblock für einen der oben erwähnten Bolzen ausgebildet ist. An diesem Lagerblock ist seitlich ein Positionsmessungssensor montiert, der die Auslenkung der Kolbenstange einer jeweiligen Hydraulikzylindereinheit misst und ein entsprechendes Messsignal zur Weiterleitung an einen Regler für eine Positionsregelung bzw. Strangdickenregelung erzeugt. Aufgrund der Montage der Positionsmessungssensoren seitlich an den oberen Lagerblöcken der Hydraulikzylindereinheiten ist eine einfache Wartung der Sensoren in der Stranggießanlage ohne Demontage des Strangführungssegments möglich. Furthermore, it is provided in further developments of the presented strand guide segment, that the hydraulic cylinder units and / or the tie rods are each clamped with split bearings and a split bearing block in its associated frame. As a result, a backlash-free connection of the upper frame is achieved to the sub-frame, so that the presented strand guide segment allows high precision of the set strand thickness. At the same time, the hydraulic cylinder units and / or the tie rods can be solved for maintenance and repair purposes without great technical effort of the upper frame or subframe. In a further development of the presented strand guide segment is also provided that the hydraulic cylinder units each have a bearing block at its first end, for example in the form that the first end of each hydraulic cylinder unit is formed as a bearing block for one of the above-mentioned bolts. At this bearing block, a position measuring sensor is mounted laterally, which measures the deflection of the piston rod of a respective hydraulic cylinder unit and generates a corresponding measurement signal for transmission to a controller for position control or strand thickness control. Due to the mounting of the position measurement sensors laterally on the upper bearing blocks of the hydraulic cylinder units, easy maintenance of the sensors in the continuous casting plant without disassembly of the strand guide segment is possible.

Komponenten des Ausführungsbeispiels des vorgestellten Strangführungssegments dar.  Components of the embodiment of the presented strand guide segment.
In Fig. 1 ist ein Ausführungsbeispiel des vorgestellten Strangführungssegments in perspektivischer Darstellung veranschaulicht. Das Strangführungssegment 50 weist einen Oberrahmen 8 und einen Unterrahmen 9 auf, deren Abstand zueinander entlang der Führung durch Seitenrahmen 20A und 20B veränderbar ist. Das Strangführungssegment 50 ist zum Führen eines Strangs, insbesondere aus teilerstarrtem Metall, und Einstellen der Strangdicke dieses Strangs ausgebildet. Zu diesem Zweck sind an dem Oberrahmen 8 gelagerte Rollen 21 und an dem Unterrahmen 9 gelagerte Rollen 22 vorgesehen, zwischen denen der Strang geführt wird, und wobei Abstand zwischen den Rollen 21 und 22 die durch das Strangführungssegment 50 eingestellte Strangdicke bestimmt. Der Abstand wird durch vier Hydraulikzylindereinheiten 1 mit damit jeweils verbundenen Zugstangen 2 eingestellt, die an den vier äußeren Ecken des Strangführungssegments 50 angeordnet sind. In Fig. 1, an embodiment of the presented strand guide segment is illustrated in a perspective view. The strand guide segment 50 has an upper frame 8 and a lower frame 9, whose distance from each other along the guide by side frames 20A and 20B is variable. The strand guide segment 50 is designed for guiding a strand, in particular of partially solidified metal, and adjusting the strand thickness of this strand. For this purpose, rollers 21 mounted on the upper frame 8 and rollers 22 mounted on the lower frame 9 are provided, between which the strand is guided, and wherein the distance between the rollers 21 and 22 determines the strand thickness set by the strand guiding segment 50. The distance is adjusted by four hydraulic cylinder units 1 with tie rods 2 respectively connected thereto, which are arranged at the four outer corners of the strand guide segment 50.
Die Hydraulikzylindereinheiten 1 sind mittels einer jeweiligen Flanschvorrichtung 3 lösbar mit der jeweiligen Zugstange 2 verbunden. Das dem Oberrahmen 8 zugewandte Ende jeder Hydraulikzylindereinheit 1 ist als Lagerblock 1 1 ausgestaltet, an dem seitlich ein Positionsmessungssensor 10 montiert ist. Der Lagerblock 1 1 ist zur Aufnahme eines Bolzen 5 ausgebildet, der wiederum durch geteilte Lagerschalen 6 und einen geteilten Lagerblock 7, die an dem Oberrahmen 8 vorgesehen bzw. montiert sind, in dem Oberrahmen 8 geklemmt ist. Der Lagerblock 1 1 einer jeweiligen Hydraulikzylindereinheit 1 ist mittels eines spielarm ausgestalteten Gelenklagers 4 auf dem Bolzen 5 gelagert. Jede Hydraulikzylindereinheit 1 ist axial in Richtung des Unterrahmens 9 ausgerichtet, wobei jede Hydraulikzylindereinheit 1 an ihrem von dem Oberrahmen 2 abgewandten Ende eine Kolbenstange 1A aufweist. Diese Kolbenstange 1A ist mit der Flanschvorrichtung 3 verbunden, die wiederum mit der Zugstange 2 verbunden ist. The hydraulic cylinder units 1 are detachably connected to the respective drawbar 2 by means of a respective flange device 3. The upper frame 8 facing the end of each hydraulic cylinder unit 1 is as a bearing block 1 first configured on the side of a position measurement sensor 10 is mounted. The bearing block 1 1 is designed to receive a pin 5, which in turn is clamped by split bearing shells 6 and a split bearing block 7, which are provided or mounted on the upper frame 8, in the upper frame 8. The bearing block 1 1 of a respective hydraulic cylinder unit 1 is mounted on the bolt 5 by means of a play arm designed hinge bearing 4. Each hydraulic cylinder unit 1 is aligned axially in the direction of the subframe 9, wherein each hydraulic cylinder unit 1 has a piston rod 1A at its end facing away from the upper frame 2. This piston rod 1A is connected to the flange device 3, which in turn is connected to the tie rod 2.
Die Zugstange 2 ist an ihrem von der Flanschvorrichtung 3 abgewandten Ende an dem Unterrahmen 9 gelagert. Genauer genommen ist die Zugstange 2 an diesem Ende mittels eines spielarmen Gelenklagers 14 auf einem Bolzen 15 gelagert. Der Bolzen 15, und somit auch die Zugstange 2, ist mittels geteilter Lagerschalen 16 und eines geteilten Lagerblocks 17 in dem Unterrahmen 9 geklemmt. The pull rod 2 is mounted at its end remote from the flange 3 end to the subframe 9. More precisely, the drawbar 2 is mounted on a bolt 15 at this end by means of a low-play spherical bearing 14. The bolt 15, and thus also the pull rod 2, is clamped by means of split bearing shells 16 and a split bearing block 17 in the subframe 9.
In Fig. 1 ist der vordere linke Abschnitt des Strangführungssegments 50 in einer vereinfachten perspektivischen Schnittansicht der Hydraulikzylindereinheit 1 mit ihrer Kolbenstange 1A, der Flanschvorrichtung 3, der Zugstange 2, den Gelenklagern 4,14, der Bolzen 5, 15 und der geteilten Lagerschalen 6, 16 dargestellt. In Fig. 2A ist diese Schnittansicht hingegen detailliert zweidimensional dargestellt. Bei dem veranschaulichten Ausführungsbeispiel ist die Flanschvorrichtung 3 kraftschlüssig mit dem von dem Oberrahmen 8 abgewandten Endabschnitt der Kolbenstange 1A verbunden. Beispielsweise kann die Flanschvorrichtung 3 thermisch auf den Endabschnitt der Kolbenstange 1A aufgeschrumpft worden sein. Die Flanschvorrichtung 3 ist mittels mehrerer Schrauben 12, die in axialer Richtung der Kolbenstange 1A ausgerichtet sind, mit dem von dem Unterrahmen 9 abgewandten und verbreitert ausgestalteten Endabschnitt der Zugstange 2 verbunden. Während des Gießbetriebs stellen die Schrauben 12 eine starre Verbindung zwischen der Kolbenstange 1A und der Zugstange 2 her. Für Wartungsarbeiten können die Schrauben 12 gelöst werden, so dass die Flanschvorrichtung 3 und somit auch die Kolbenstange 1A der Hydraulikzylindereinheit 1 von der Zugstange 2 getrennt bzw. entkoppelt werden kann. Dadurch kann bei Wartungsarbeiten der Oberrahmen 8 von dem Unterrahmen 9 getrennt werden, ohne dass die Lagerungen am Oberrahmen oder Unterrahmen geöffnet werden müssen. In Fig. 1, the front left portion of the strand guide segment 50 in a simplified perspective sectional view of the hydraulic cylinder unit 1 with its piston rod 1A, the flange 3, the tie rod 2, the joint bearings 4,14, the bolt 5, 15 and the split bearing shells 6, 16 shown. In contrast, in FIG. 2A, this sectional view is shown in detail in two dimensions. In the illustrated embodiment, the flange device 3 is non-positively connected to the end portion of the piston rod 1A facing away from the upper frame 8. For example, the flange device 3 may have been thermally shrunk onto the end portion of the piston rod 1A. The flange device 3 is connected by means of a plurality of screws 12, which are aligned in the axial direction of the piston rod 1A, with the remote from the sub-frame 9 and widened end portion of the tie rod 2. During the casting operation, the Screw 12 a rigid connection between the piston rod 1A and the pull rod 2 ago. For maintenance, the screws 12 can be solved so that the flange 3 and thus also the piston rod 1 A of the hydraulic cylinder unit 1 can be disconnected from the pull rod 2 and decoupled. As a result, during maintenance work, the upper frame 8 can be separated from the lower frame 9 without the bearings having to be opened on the upper frame or lower frame.
Fig. 2B zeigt eine Ansicht auf einen Schnitt entlang der Linien B-B in Fig. 2A. Wie aus Fig. 2B ersichtlich, ist der Positionsmessungssensor 10 seitlich am Lagerblock 1 1 der Hydraulikzylindereinheit 1 im Bereich des Oberrahmens 8 angebracht. Daher kann der Positionsmessungssensor 10 einfach in der Stranggießanlage ohne Demontage des Strangführungssegments 50 gewartet werden. Fig. 2B is a sectional view taken along lines BB in Fig. 2A. As can be seen from FIG. 2B, the position-measuring sensor 10 is attached laterally to the bearing block 11 of the hydraulic cylinder unit 1 in the region of the upper frame 8. Therefore, the position measurement sensor 10 can be easily maintained in the continuous caster without disassembling the strand guide segment 50.
