Description

Die Erfindung betrifft ein Strangführungssegment einer Stranggießanlage, umfassend einen Oberrahmen und einen Unterrahmen, wobei zwischen dem Oberrahmen und dem Unterrahmen Hydraulikzylindereinheiten zum Einstellen des Abstandes zwischen Oberrahmen und dem Unterrahmen angeordnet sind, wobei ein Teil der Hydraulikzylindereinheit über eine erste Lagerstelle mit dem Oberrahmen verbunden ist und ein Teil der Hydraulikzylindereinheit über eine zweite Lagerstelle mit dem Unterrahmen verbunden ist.The invention relates to a strand guide segment of a continuous casting installation, comprising an upper frame and a lower frame, hydraulic cylinder units for adjusting the distance between the upper frame and the lower frame being arranged between the upper frame and the lower frame, part of the hydraulic cylinder unit being connected to the upper frame via a first bearing point and part of the hydraulic cylinder unit is connected to the subframe via a second bearing point.

Ein gattungsgemäßes Strangführungssegment ist aus der DE 19 63 146 C1 bekannt. Das Segment wird durch einen Oberrahmen und einem diesem gegenüberliegenden Unterrahmen gebildet, wobei zwecks Einstellens eines definierten Abstands zwischen dem Oberrahmen und dem Unterrahmen und dadurch einer Strangdicke eines durch das Strangführungssegment zu führenden Strangs Hydraulikzylindereinheiten vorgesehen sind, mit denen der Abstand positionsgeregelt auf einem gewünschten Wert gehalten werden kann. Eine ähnliche Lösung offenbart die WO 2006/050868 A1 . Positionsgeregelte Hydraulikzylinder zum Einstellen der Formatdicke des Strangs sind insoweit vorbekannt.A generic strand guide segment is from the DE 19 63 146 C1 known. The segment is formed by an upper frame and a lower frame opposite this, for the purpose of setting a defined distance between the upper frame and the lower frame and thereby a strand thickness of a strand to be guided through the strand guide segment, hydraulic cylinder units are provided with which the distance is held in a position-controlled manner at a desired value can be. A similar solution discloses the WO 2006/050868 A1 , Position-controlled hydraulic cylinders for setting the format thickness of the strand are previously known.

Für Wartungsarbeiten am Strangführungssegment müssen der Oberrahmen und der Unterrahmen voneinander getrennt bzw. entkoppelt werden. Dazu müssen die jeweiligen Lagerungen der Hydraulikzylindereinheiten am Oberrahmen oder am Unterrahmen geöffnet werden.The upper frame and the lower frame must be separated or decoupled from one another for maintenance work on the strand guide segment. To do this, the respective bearings of the hydraulic cylinder units on the upper frame or on the lower frame must be opened.

Zum einfachen Öffnen der Lagerung ist allerdings ein erhebliches Spiel erforderlich, das sich bei einem zusammengebauten Segment im Gießbetrieb nachteilig auf die Einstellung der Formatdicke auswirkt.To open the storage easily, however, considerable play is required, which has an adverse effect on the setting of the format thickness in an assembled segment in the casting operation.

Die Ergebnisse der Messungen der Formatdicke in der Strangführung mit einem "Roll Gap Checker" sind teilweise stark abweichend von den in der Strangführung mit den positionsgeregelten Hydraulikzylindern tatsächlich eingestellten Formatdicken.The results of the measurements of the format thickness in the strand guide with a "Roll Gap Checker" are sometimes very different from the format thicknesses actually set in the strand guide with the position-controlled hydraulic cylinders.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Strangführungssegment so auszugestalten, dass eine möglichst spielarme Anbindung des Oberrahmens an den Unterrahmen eines Segments gegeben ist, dennoch aber eine einfache Öffnung der Lagerung möglich ist. Damit soll die Wartung des Segments vereinfacht werden. Weiterhin soll die Genauigkeit der durch das Segment eingestellten Strangdicke erhöht werden.The object of the invention is to design a strand guide segment of the generic type in such a way that the upper frame is connected to the lower frame of a segment with as little play as possible, but nevertheless a simple opening of the bearing is possible. This is to simplify the maintenance of the segment. Furthermore, the accuracy of the strand thickness set by the segment is to be increased.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass mindestens eine der Lagerstellen umfasst: ein Lager mit mindestens einem Innenring und mindestens einem Außenring, wobei ein Teil der Hydraulikzylindereinheit mit dem mindestens einen Innenring verbunden ist, sowie ein Gehäuseelement, in dem der mindestens eine Außenring angeordnet ist, wobei am Gehäuseelement ein sich radial erweiterter Flansch angeordnet ist, wobei das Gehäuseelement mittels des Flansches am Oberrahmen oder am Unterrahmen befestigt (insbesondere festgeschraubt) ist.The solution to this problem by the invention is characterized in that at least one of the bearing points comprises: a bearing with at least one inner ring and at least one outer ring, part of the hydraulic cylinder unit being connected to the at least one inner ring, and a housing element in which the at least one an outer ring is arranged, a radially widened flange being arranged on the housing element, the housing element being fastened (in particular screwed) to the upper frame or to the lower frame by means of the flange.

Das Gehäuseelement ist dabei bevorzugt mittels des Flansches am Oberrahmen befestigt.The housing element is preferably attached to the upper frame by means of the flange.

Das Lager weist vorzugsweise zwei Innenringe und zwei Außenringe auf, wobei ein sich radial erweiterter Abschnitt des Teil der Hydraulikzylindereinheit zwischen den beiden Innenringen angeordnet ist. Dabei ist bevorzugt vorgesehen, dass die beiden Außenringe im Gehäuseelement axial beabstandet angeordnet sind und vorzugsweise von radial nach innen vorspringenden Abschnitten des Gehäuseelements axial festgelegt sind.The bearing preferably has two inner rings and two outer rings, a radially widened section of the part of the hydraulic cylinder unit being arranged between the two inner rings. It is preferably provided that the two outer rings are axially spaced in the housing element and are preferably axially fixed from radially inwardly projecting sections of the housing element.

Das Lager ist bevorzugt als Axialgleitlager ausgebildet. Dabei liegt bevorzugt eine konvexe Lagerfläche des Innenrings an einer konkaven Lagerfläche des Außenrings an.The bearing is preferably designed as an axial sliding bearing. In this case, a convex bearing surface of the inner ring preferably lies against a concave bearing surface of the outer ring.

Das Gehäuseelement mit den sich in diesem befindlichen Lagerringen ist bevorzugt als gekapselte Einheit ausgebildet.The housing element with the bearing rings located therein is preferably designed as an encapsulated unit.

Am oder im Gehäuseelement ist bevorzugt ein Sensor zur Erfassung der Verschiebung zwischen Kolben und Zylinder der Hydraulikzylindereinheit angeordnet. Dabei sieht eine bevorzugte Ausführungsform der Erfindung vor, dass der Sensor im Bereich der Längsachse der Hydraulikzylindereinheit am oder im Gehäuseelement angeordnet ist. Besonders bevorzugt ist vorgesehen, dass der Sensor zur Erfassung der Bewegung eines starren Messstabes ausgebildet ist, der mit dem Kolben der Hydraulikzylindereinheit verbunden ist.A sensor for detecting the displacement between the piston and cylinder of the hydraulic cylinder unit is preferably arranged on or in the housing element. A preferred embodiment of the invention provides that the sensor is arranged on or in the housing element in the region of the longitudinal axis of the hydraulic cylinder unit. It is particularly preferably provided that the sensor is designed to detect the movement of a rigid measuring rod which is connected to the piston of the hydraulic cylinder unit.

Somit stellt die vorliegende Erfindung gemäß einer bevorzugten Ausführungsform auf die Anordnung der Axiallager in einem gekapselten Lagerbock ab, der eine Sockelplatte (Flansch) aufweist, mit der die spielarme Anbindung der Zylindereinheit im Oberrahmen des Segments möglich wird.Thus, according to a preferred embodiment, the present invention is based on the arrangement of the axial bearings in an encapsulated bearing block which has a base plate (flange) with which the low-play connection of the cylinder unit in the upper frame of the segment is possible.

Dabei ist insbesondere der Sensor der Positionsmessung oberhalb der Zylindereinheit mittig in die Zugstange der Hydraulikzylindereinheit montiert.In particular, the sensor for position measurement above the cylinder unit is mounted centrally in the pull rod of the hydraulic cylinder unit.

Mit der erfindungsgemäßen Ausgestaltung wird ein Segment für die Strangführung in einer Stranggießanlage zur Verfügung gestellt, die sich durch eine spielarme Anbindung des Oberrahmens zum Unterrahmen des Segments auszeichnet.With the configuration according to the invention, a segment for the strand guidance in a continuous casting installation is made available, which is characterized by a low-play connection of the upper frame to the lower frame of the segment.

Es ergibt sich vorteilhaft die Minimierung der Abweichung zwischen den Ergebnissen aus den Messungen mit einem "Roll Gap Checker" zu den eingestellten Formatdicken aufgrund der spielarmen Lagerung der Zylindereinheit. Die Position des Sensors für die Positionsmessung mittig oberhalb der Zugstange ermöglicht den Einsatz von Sensoren mit starrem Messstab. Diese Position des Sensors für die Positionsmessung ermöglicht weiterhin die einfache Wartung des Sensors in der Anlage ohne Demontage des Segments.This advantageously minimizes the deviation between the results from the measurements with a "roll gap checker" and the set format thicknesses due to the low-play mounting of the cylinder unit. The position of the sensor for position measurement in the middle above the drawbar enables the use of sensors with a rigid dipstick. This position of the sensor for position measurement also enables easy maintenance of the sensor in the system without dismantling the segment.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:

In the drawing, an embodiment of the invention is shown. Show it:
Fig. 1

Fig. 2
the radial section through a hydraulic cylinder unit with which the upper frame is held at a defined distance relative to the lower frame.

In Figur 1 ist ein Strangführungssegment 1 dargestellt, welches aus einem Oberrahmen 2 und einem Unterrahmen 3 besteht. Zur Definition der Strangdicke eines durch das Strangführungssegment 1 zu führenden Strangs kann der Unterrahmen 3 relativ zum Oberrahmen 2 verstellt werden, wozu eine Anzahl Hydraulikzylindereinheiten 4 vorgesehen ist.In Figure 1 a strand guide segment 1 is shown, which consists of an upper frame 2 and a lower frame 3. To define the strand thickness of a strand to be guided through the strand guide segment 1, the lower frame 3 can be adjusted relative to the upper frame 2, for which purpose a number of hydraulic cylinder units 4 are provided.

Die Hydraulikzylindereinheiten 4 sind positionsgeregelt, sodass ein genauer Abstand zwischen Oberrahmen 2 und Unterrahmen 3 eingestellt und eingehalten werden kann.The hydraulic cylinder units 4 are position-controlled so that a precise distance between the upper frame 2 and the lower frame 3 can be set and maintained.

Der Aufbau sowie die Anbindung der Hydraulikzylindereinheiten 4 am Oberrahmen 2 und am Unterrahmen 3 gehen in der Zusammenschau mit Figur 2 hervor.The structure and the connection of the hydraulic cylinder units 4 to the upper frame 2 and to the lower frame 3 go together Figure 2 out.

Hieraus ist ersichtlich, dass die Hydraulikzylindereinheit 4 an einer ersten Lagerstelle 5 mit dem Oberrahmen 2 verbunden ist, während dieIt can be seen from this that the hydraulic cylinder unit 4 is connected to the upper frame 2 at a first bearing point 5, while the

Hydraulikzylindereinheit 4 an einer zweiten Lagerstelle 6 mit dem Unterrahmen 3 verbunden ist.Hydraulic cylinder unit 4 is connected to the subframe 3 at a second bearing point 6.

Die zweite, untere Lagerstelle 5 wird vorliegend in üblicher Weise durch einen Bolzen 17 realisiert, der ein Gelenklager 20 zwischen der Zugstange 18 und dem Unterrahmen 3 festlegt.The second, lower bearing point 5 is realized in the present manner in the usual way by a bolt 17 which fixes a spherical bearing 20 between the pull rod 18 and the subframe 3.

Demgegenüber ist die erste Lagerstelle 5, mit der die Hydraulikzylindereinheit 4 am Oberrahmen 2 festgelegt ist, in spezieller Weise ausgebildet:
Besagte Lagerstelle 5 umfasst ein Lager 7, welches im Ausführungsbeispiel zwei Innenringe 8 und 9 sowie zwei Außenringe 10 und 11 aufweist. Das Lager 7 ist nach Art eines Axialgleitlagers ausgeführt. Ein Teil der Hydraulikzylindereinheit 4 ist mit den beiden Innenringen 8 und 9 dergestalt verbunden, dass ein radial erweiterter Abschnitt 14 eines Teils der Hydraulikzylindereinheit 4 von den beiden Innenringen 8, 9 axial eingefasst wird (siehe Figur 2). Die beiden Außenringe 10 und 11 sind indes in einem hohlzylindrisch ausgebildeten Gehäuseelement 12 mit axialem Abstand angeordnet und in diesem festgelegt, wobei das Gehäuseelement 12 eine abgeschlossene Lageeinheit bildet, die das axiale Ende der Zugstange 21 der Hydraulikzylindereinheit 4 lagert. Fest mit dem Gehäuseelement 12 verbunden ist ein Flansch 13, der mit einer Anzahl Schrauben 24 (siehe hierzu Figur 1) am Oberrahmen 2 befestigt ist.In contrast, the first bearing 5, with which the hydraulic cylinder unit 4 is fixed to the upper frame 2, is designed in a special way:
Said bearing point 5 comprises a bearing 7, which in the exemplary embodiment has two inner rings 8 and 9 and two outer rings 10 and 11. The bearing 7 is designed in the manner of an axial sliding bearing. A part of the hydraulic cylinder unit 4 is connected to the two inner rings 8 and 9 such that a radially widened section 14 of a part of the hydraulic cylinder unit 4 is axially enclosed by the two inner rings 8, 9 (see Figure 2 ). The two outer rings 10 and 11 are, however, arranged in a hollow cylindrical housing element 12 with an axial spacing and fixed therein, the housing element 12 forming a closed position unit which supports the axial end of the pull rod 21 of the hydraulic cylinder unit 4. A flange 13 is fixedly connected to the housing element 12 and is secured with a number of screws 24 (see also Figure 1 ) is attached to the upper frame 2.

Der Kolben 22 der Hydraulikzylindereinheit 4 ist mit einer Kolbenstange 23 verbunden, die mittels einer Flanschvorrichtung 19 mit der unteren Zugstange 18 verbunden ist.The piston 22 of the hydraulic cylinder unit 4 is connected to a piston rod 23 which is connected to the lower tie rod 18 by means of a flange device 19.

Ferner ist ein Sensor 15 vorgesehen, der mittig oberhalb der Zugstange 21 und somit mittig am oder im Gehäuseelement 12 angeordnet ist. Dieser Sensor 15 ist ausgebildet, die Verschiebung eines starren Messstabes 16 und somit die aktuelle Auslenkung der Hydraulikzylindereinheit 4 zu erfassen.Furthermore, a sensor 15 is provided, which is arranged centrally above the pull rod 21 and thus centrally on or in the housing element 12. This sensor 15 is designed to detect the displacement of a rigid measuring rod 16 and thus the current deflection of the hydraulic cylinder unit 4.

Durch die Möglichkeit, den Flansch 13, der mit dem Gehäuseelement 12 verbunden ist, durch Lösen der entsprechenden Schrauben 24 (siehe Figur 1) vom Oberrahmen 2 zu entfernen, besteht der vorteilhafte Effekt, eine spielarme Anbindung des Oberrahmens 2 am Unterrahmen 3 zu realisieren.The possibility of the flange 13, which is connected to the housing element 12, by loosening the corresponding screws 24 (see Figure 1 ) to remove from the upper frame 2, there is the advantageous effect of realizing a low-play connection of the upper frame 2 to the lower frame 3.
