Definitions
- the present invention relates to a strand guide element for guiding and supporting a metallic strand in a continuous casting machine.
- Strand-guiding elements for guiding and supporting a metallic strand in a curved or straight strand guide of a continuous casting machine are known to the person skilled in the art, inter alia, under the designations strand-guiding segment, strand-guiding element or segment.
- a strand-guiding element has an inner frame and an outer frame (also referred to as inner-arch or outer-arch frame or as upper or lower frame in curved continuous casting plants), with the inner and outer frames each having a plurality of strand-guiding rollers for supporting and guiding the strand.
- the strand-guiding element can typically be designed with an adjustment device either at one end or at both ends of the element, with the distance between the inner frame and the outer frame being transverse, i.e. normal, to the casting direction of the strand can be changed by the adjusting device.
- a particularly simple construction of the strand guide element can be achieved if a bearing is arranged in the casting direction of the strand at one end of the strand guide element for the articulated connection of the inner frame to the outer frame, with such constructions also being referred to as so-called "Zangssegment", “Zangenbender” or "tong -type segment".
- an articulated connection of the inner frame to the outer frame by means of a bearing means that the inner frame allows relative rotation relative to the outer frame, with this movement not necessarily having to be torque-free.
- a disadvantage of the solutions according to the prior art is that mechanical play between the inner and outer frame is caused by manufacturing and application-related tolerances in the bearing or the adjustment device, so that a play-free connection between these components cannot be achieved.
- This so-called “play”, which represents a mechanical hysteresis results in deviations in the thickness direction (i.e. between the set distance between the inner and outer frame and the thickness of the strand itself, so that the actual thickness deviates from the nominal thickness of the strand ) or in the transverse direction (i.e. between the thickness of the left and right strand cross-section), in both cases the strand has lower dimensional accuracy and thereby lower quality.
- the object of the invention is to either significantly reduce the mechanical play of a bearing of a strand guide element for connecting the inner frame to the outer frame or to create a bearing that is completely free of play.
- the bearing has at least one rod-shaped component, the first end of which is firmly clamped in the inner frame and the second end of which is firmly clamped in the outer frame, the rod-shaped component preventing the movement of the inner frame relative to the outer frame picks up.
- a rod-shaped component i.e. a component whose longitudinal extent is greater than its transverse extent
- the inner frame with the outer frame is free of play in the area of the bearing, i.e. both in the direction of thickness and in a direction transverse to the thickness and casting directions.
- An advantageous embodiment consists in the rod-shaped component being designed as a bending rod, with the bending rod absorbing the bending stress during the movement of the inner frame relative to the outer frame.
- Both the bending rod itself and its structural design are well known to the person skilled in the art, so that the bending rod can be easily adapted to the opening angle of the strand-guiding element that is to be expected.
- the bending rod is designed as a leaf spring, a leaf spring assembly or a tension rod.
- the mechanical stresses that occur in a leaf spring, a set of leaf springs or a tension rod are well known to those skilled in the art from the literature, so that these components can be adapted very well to the loads that occur.
- the bearing also has a swivel joint, with the swivel joint representing an additional guide during the movement of the inner frame relative to the outer frame. This improves the guidance accuracy on the one hand and the axial guidance on the other hand when the inner frame rotates relative to the outer frame.
- One embodiment consists in forming the rotary joint from a rotary eyelet and a rotary guide, the rotary eyelet being connected to the inner frame and the rotary guide being connected to the outer frame.
- the swivel eye is connected to the outer frame and the swivel guide is connected to the inner frame.
- an axis of rotation of the rotary joint is arranged coaxially, i.e. with matching axes of rotation, to an axis of rotation of a strand guide roller, preferably the first in the casting direction.
- the rod-shaped component is designed as a torsion bar, with the torsion bar absorbing the torsional stress when the inner frame moves relative to the outer frame.
- the torsion bar itself and its structural design are also well known to those skilled in the art, so that the torsion bar can be easily adapted to the expected opening angle of a strand-guiding element.
- the torsion bar has a round, elliptical, rectangular or square solid or hollow cross section.
- Round or elliptical cross-sections for example, have significantly lower stress concentration factors than square or rectangular cross-sections, so that torsion bars with these cross-sections can either be designed lighter or have a longer service life with the same average stresses.
- the torsion bar is formed from a torsionally stiff element and a torsionally soft element, preferably a torsion spring.
- a torsionally stiff element e.g. a torsion bar with full cross-section
- very low rigidity of a torsionally soft element e.g. a torsion spring.
- the terms torsionally stiff and torsionally soft are to be understood in relative terms, i.e. the torsional stiffness of the torsionally stiff element is significantly (e.g. 5 times) greater than the torsional stiffness of the torsionally soft element.
- the bearing is arranged at the upper end and the adjustment device is arranged at the lower end of the strand guide element.
- the fixed clamping takes place by means of a form-fitting or a friction-fitting connection; e.g. the first end and/or the second end of the rod-shaped component is positively or frictionally connected to the inner frame or the outer frame.
- a form-fitting and a friction-fitting connection are well suited for clamping a rod-shaped component.
- the adjusting device has a first end, at least one bending rod and a second end, with the first end of the adjusting device being firmly clamped in the inner frame and the second end of the adjusting device being firmly clamped in the outer frame, and the bending rod absorbing the bending stress during movement of the inner frame relative to the outer frame.
- the adjusting device is designed as a pressure medium cylinder, the piston rod of which is designed as a flexible rod.
- the piston rod of which is designed as a flexible rod.
- the adjusting device For a high adjustment accuracy of the strand guide element, it is advantageous to form the adjusting device with a measuring device for measuring the distance between the inner frame and the outer frame. It is also advantageous to integrate the measuring device into the pressure medium cylinder or to measure directly on the piston or the tie rod (centrally).
- a shim or an actuating element for adapting the strand-guiding element to different cast thicknesses is arranged between the rod-shaped component and the inner or outer frame.
- strand-guiding element in a continuous casting machine for producing a strand, preferably with a cross-section for slabs or thin slabs, from steel.
- the strand-guiding element at the same time as a bending segment for deflecting the strand from a vertical to a curved direction, with at least one strand-guiding roller being designed as a driven roller for this use.
- the strand guide element can also be used at any other position in the strand guide where a greater reduction in thickness is to take place.
- FIG. 1 shows a front view of a strand-guiding element designed as a strand-guiding segment 1 of a curved continuous casting machine for the production of steel slabs.
- liquid steel is cast in a mold to form an at least partially solidified cast strand, which is guided, supported and further cooled in the subsequent curved strand guide formed from several strand guide segments that follow one another in the casting direction.

- the outer frame 3 can be rotated by ⁇ 5° relative to the inner frame 2 about the bearing 5—the bearing 5 has a rotary joint 14 that includes a rotary eye 15 and a rotary guide 16 .
- the bending rod is prestressed by means of the nuts 7 and is thus also a tension rod 13 the strand guide segment can be easily adapted to different strand thicknesses by means of the shims 24 . It is of course also possible to replace the shim 24 with an actuating element (eg a hydraulic cylinder) so that the adjustment can be automated, ie controlled or regulated.

Description
Die vorliegende Erfindung betrifft ein Strangführungselement zum Führen und Stützen eines metallischen Strangs in einer Stranggießmaschine.The present invention relates to a strand guide element for guiding and supporting a metallic strand in a continuous casting machine.
Konkret betrifft die Erfindung ein Strangführungselement zum Führen und Stützen eines metallischen Strangs in einer Stranggießmaschine, aufweisend
- einen Innenrahmen;
- einen Außenrahmen, wobei jeweils der Innenrahmen und der Außenrahmen mehrere Strangführungsrollen zum Führen und Stützen des Strangs aufweisen;
- wenigstens ein Lager zur gelenkigen Verbindung des Innenrahmens mit dem Außenrahmen; und
- eine Verstelleinrichtung zur Änderung eines Abstands zwischen dem Innenrahmen und dem Außenrahmen, wobei die Änderung des Abstands in einer Richtung quer zu der Gießrichtung erfolgt.
- an inner frame;
- an outer frame, each of the inner frame and the outer frame having a plurality of strand guide rollers for guiding and supporting the strand;
- at least one bearing for the articulated connection of the inner frame to the outer frame; and
- an adjusting device for changing a distance between the inner frame and the outer frame, the change of the distance being in a direction transverse to the casting direction.
Strangführungselemente zum Führen und Stützen eines metallischen Strangs in einer bogenförmigen oder einer geraden Strangführung einer Stranggießmaschine sind dem Fachmann unter anderem unter den Bezeichnungen Strangführungssegment, Strangführungselement oder Segment bekannt. Dabei weist ein Strangführungselement einen Innenrahmen und einen Außenrahmen (bei bogenförmigen Stranggießanlagen auch als Innenbogen- bzw. Außenbogenrahmen oder als Ober- bzw. Unterrahmen bezeichnet) auf, wobei jeweils der Innen- und der Außenrahmen mehrere Strangführungsrollen zum Stützen und Führen des Strangs aufweisen. Um das Strangführungselement an unterschiedliche Gießdicken des Strangs anpassen zu können, ist es bekannt, das Strangführungselement typischerweise entweder an einem Ende oder an beiden Enden des Elements mit einer Verstelleinrichtung auszubilden, wobei der Abstand zwischen dem Innenrahmen und dem Außenrahmen quer, d.h. normal, zur Gießrichtung des Strangs durch die Verstelleinrichtung verändert werden kann. Eine besonders einfache Konstruktion des Strangführungselements lässt sich erzielen, wenn in der Gießrichtung des Strangs an einem Ende des Strangführungselements zur gelenkigen Verbindung des Innenrahmens mit dem Außenrahmen ein Lager angeordnet ist, wobei derartige Konstruktionen auch als sogenannte "Zangensegment", "Zangenbender" oder "tong-type segment" bezeichnet werden. In diesem Zusammenhang ist unter einer gelenkigen Verbindung des Innenrahmens mit dem Außenrahmen mittels eines Lagers des zu verstehen, dass der Innenrahmen gegenüber dem Außenrahmen eine Relativverdrehung zulässt, wobei diese Bewegung nicht notwendigerweise drehmomentenfrei erfolgen muss.Strand-guiding elements for guiding and supporting a metallic strand in a curved or straight strand guide of a continuous casting machine are known to the person skilled in the art, inter alia, under the designations strand-guiding segment, strand-guiding element or segment. In this case, a strand-guiding element has an inner frame and an outer frame (also referred to as inner-arch or outer-arch frame or as upper or lower frame in curved continuous casting plants), with the inner and outer frames each having a plurality of strand-guiding rollers for supporting and guiding the strand. In order to be able to adapt the strand-guiding element to different casting thicknesses of the strand, it is known that the strand-guiding element can typically be designed with an adjustment device either at one end or at both ends of the element, with the distance between the inner frame and the outer frame being transverse, i.e. normal, to the casting direction of the strand can be changed by the adjusting device. A particularly simple construction of the strand guide element can be achieved if a bearing is arranged in the casting direction of the strand at one end of the strand guide element for the articulated connection of the inner frame to the outer frame, with such constructions also being referred to as so-called "Zangssegment", "Zangenbender" or "tong -type segment". In this context, an articulated connection of the inner frame to the outer frame by means of a bearing means that the inner frame allows relative rotation relative to the outer frame, with this movement not necessarily having to be torque-free.
Nachteilig an den Lösungen nach dem Stand der Technik ist, dass durch fertigungs- und anwendungsbedingte Toleranzen beim Lager oder der Verstelleinrichtung ein mechanische Spiel zwischen Innen- und Außenrahmen bedingt wird, sodass keine spielfreie Verbindung zwischen diesen Bauteilen erzielt werden kann. Durch dieses sogenannte "Spiel", das eine mechanische Hysterese darstellt, ergeben sich beispielsweise Abweichungen in Dickenrichtung (d.h. zwischen dem eingestellten Abstand zwischen Innen- und Außenrahmen und der Dicke des Strangs selbst, sodass die Ist-Dicke von der Soll-Dicke des Strangs abweicht) oder in der Querrichtung (d.h. zwischen der Dicke des linken und rechten Strangquerschnitts), wobei in beiden Fällen der Strang eine niedrigere Maßhaltigkeit und dadurch niedrigere Qualität aufweist.A disadvantage of the solutions according to the prior art is that mechanical play between the inner and outer frame is caused by manufacturing and application-related tolerances in the bearing or the adjustment device, so that a play-free connection between these components cannot be achieved. This so-called "play", which represents a mechanical hysteresis, results in deviations in the thickness direction (i.e. between the set distance between the inner and outer frame and the thickness of the strand itself, so that the actual thickness deviates from the nominal thickness of the strand ) or in the transverse direction (i.e. between the thickness of the left and right strand cross-section), in both cases the strand has lower dimensional accuracy and thereby lower quality.
Aufgabe der Erfindung ist es, das mechanische Spiel eines Lagers eines Strangführungselements zur Verbindung des Innenrahmens mit dem Außenrahmen entweder deutlich zu reduzieren oder ein gänzlich spielfreies Lager zu schaffen.The object of the invention is to either significantly reduce the mechanical play of a bearing of a strand guide element for connecting the inner frame to the outer frame or to create a bearing that is completely free of play.
Diese Aufgabe wird durch eine Vorrichtung der eingangs genannten Art gelöst, bei der das Lager wenigstens einen stabförmigen Bauteil aufweist, dessen erstes Ende in dem Innenrahmen und dessen zweites Ende in dem Außenrahmen fest eingespannt ist, wobei der stabförmige Bauteil die Bewegung des Innenrahmens gegenüber dem Außenrahmen aufnimmt. Durch das beidseitige Einspannen, d.h. das Blockieren der Freiheitsgrade für die Verschiebungen und Verdrehungen, eines stabförmigen Bauteils, d.h. eines Bauteils dessen Längserstreckung größer ist als dessen Quererstreckung, wird der Innenrahmen mit dem Außenrahmen im Bereich des Lagers spielfrei, d.h. sowohl in der Dickenrichtung als auch in einer Richtung quer zur Dicken- und zur Gießrichtung, miteinander verbunden.This object is achieved by a device of the type mentioned at the beginning, in which the bearing has at least one rod-shaped component, the first end of which is firmly clamped in the inner frame and the second end of which is firmly clamped in the outer frame, the rod-shaped component preventing the movement of the inner frame relative to the outer frame picks up. By clamping on both sides, i.e. blocking the degrees of freedom for the displacements and rotations, of a rod-shaped component, i.e. a component whose longitudinal extent is greater than its transverse extent, the inner frame with the outer frame is free of play in the area of the bearing, i.e. both in the direction of thickness and in a direction transverse to the thickness and casting directions.
Eine vorteilhafte Ausführungsform besteht darin, dass der stabförmige Bauteil als ein Biegestab ausgeführt ist, wobei der Biegestab die Biegebeanspruchung bei der Bewegung des Innenrahmens gegenüber dem Außenrahmen aufnimmt. Sowohl der Biegestab selbst als auch dessen konstruktive Auslegung sind dem Fachmann gut bekannt, sodass eine einfache Anpassung des Biegestabs an die zu erwartenden Öffnungswinkel des Strangführungselements möglich ist.An advantageous embodiment consists in the rod-shaped component being designed as a bending rod, with the bending rod absorbing the bending stress during the movement of the inner frame relative to the outer frame. Both the bending rod itself and its structural design are well known to the person skilled in the art, so that the bending rod can be easily adapted to the opening angle of the strand-guiding element that is to be expected.
In einer einfachen Ausführungsform ist der Biegestab als eine Blattfeder, ein Blattfederpaket oder ein Zugstab ausgeführt. Die auftretenden mechanischen Spannungen in einer Blattfeder, einem Blattfederpaket oder einem Zugstab sind dem Fachmann aus der Literatur gut bekannt, sodass diese Bauteile sehr gut an die auftretenden Belastungen angepasst werden können.In a simple embodiment, the bending rod is designed as a leaf spring, a leaf spring assembly or a tension rod. The mechanical stresses that occur in a leaf spring, a set of leaf springs or a tension rod are well known to those skilled in the art from the literature, so that these components can be adapted very well to the loads that occur.
In einer weiteren vorteilhaften Ausführungsform weist das Lager zusätzlich ein Drehgelenk auf, wobei das Drehgelenk eine zusätzliche Führung bei der Bewegung des Innenrahmens gegenüber dem Außenrahmen darstellt. Dadurch wird zum Einen die Führungsgenauigkeit und zum Anderen die axiale Führung bei der Relativverdrehung des Innenrahmens gegenüber dem Außenrahmen verbessert.In a further advantageous embodiment, the bearing also has a swivel joint, with the swivel joint representing an additional guide during the movement of the inner frame relative to the outer frame. This improves the guidance accuracy on the one hand and the axial guidance on the other hand when the inner frame rotates relative to the outer frame.
Eine Ausführungsform besteht darin, das Drehgelenk aus einem Drehauge und einer Drehführung zu bilden, wobei das Drehauge mit dem Innenrahmen und die Drehführung mit dem Außenrahmen verbunden ist. Bei einer dazu äquivalenten Lösung ist das Drehauge mit dem Außenrahmen und die Drehführung mit dem Innenrahmen verbunden.One embodiment consists in forming the rotary joint from a rotary eyelet and a rotary guide, the rotary eyelet being connected to the inner frame and the rotary guide being connected to the outer frame. In an equivalent solution, the swivel eye is connected to the outer frame and the swivel guide is connected to the inner frame.
Eine vorteilhafte Kinematik kann erzielt werden, wenn eine Drehachse des Drehgelenks koaxial, d.h. mit übereinstimmenden Rotationsachsen, zu einer Drehachse einer, vorzugsweise in Gießrichtung ersten, Strangführungsrolle angeordnet ist.Advantageous kinematics can be achieved if an axis of rotation of the rotary joint is arranged coaxially, i.e. with matching axes of rotation, to an axis of rotation of a strand guide roller, preferably the first in the casting direction.
Eine andere vorteilhafte Ausführungsform besteht darin, dass der stabförmige Bauteil als ein Torsionsstab ausgeführt ist, wobei der Torsionsstab die Torsionsbeanspruchung bei der Bewegung des Innenrahmens gegenüber dem Außenrahmen aufnimmt. Auch der Torsionsstab selbst als auch dessen konstruktive Auslegung sind dem Fachmann gut bekannt, sodass eine einfache Anpassung des Torsionsstabs an die zu erwartenden Öffnungswinkel eines Strangführungselements möglich ist.Another advantageous embodiment is that the rod-shaped component is designed as a torsion bar, with the torsion bar absorbing the torsional stress when the inner frame moves relative to the outer frame. The torsion bar itself and its structural design are also well known to those skilled in the art, so that the torsion bar can be easily adapted to the expected opening angle of a strand-guiding element.
In einer einfachen Ausführungsform weist der Torsionsstab einen runden, elliptischen, rechteckigen oder quadratischen Voll- oder Hohlquerschnitt auf. Runde oder elliptische Querschnitte weisen z.B. gegenüber quadratischen oder rechteckigen Querschnitten wesentlich geringere Spannungskonzentrationsfaktoren auf, sodass Torsionsstäbe mit diesen Querschnitten bei gleichen mittleren Spannungen entweder leichter ausgeführt können oder eine erhöhte Lebensdauer aufweisen.In a simple embodiment, the torsion bar has a round, elliptical, rectangular or square solid or hollow cross section. Round or elliptical cross-sections, for example, have significantly lower stress concentration factors than square or rectangular cross-sections, so that torsion bars with these cross-sections can either be designed lighter or have a longer service life with the same average stresses.
In einer weiteren Ausführungsform ist der Torsionsstab aus einem torsionssteifen Element und einem torsionsweichen Element, vorzugsweise einer Torsionsfeder, gebildet. Dadurch ist es möglich, eine hohe Steifigkeit eines torsionssteifen Elements, z.B. eines Torsionsstabs mit Vollquerschnitt, mit einer sehr geringen Steifigkeit eines torsionsweichen Elements, z.B. einer Torsionsfeder, zu kombinieren. Hierbei sind die Begriffe torsionssteif und torsionsweich jeweils relativ zu verstehen, d.h. dass die Torsionssteifigkeit des torsionssteifen Elements wesentlich (beispielsweise 5 Mal) größer als die Torsionssteifigkeit des torsionsweichen Elements ist.In a further embodiment, the torsion bar is formed from a torsionally stiff element and a torsionally soft element, preferably a torsion spring. This makes it possible to combine high rigidity of a torsionally stiff element, e.g. a torsion bar with full cross-section, with very low rigidity of a torsionally soft element, e.g. a torsion spring. Here, the terms torsionally stiff and torsionally soft are to be understood in relative terms, i.e. the torsional stiffness of the torsionally stiff element is significantly (e.g. 5 times) greater than the torsional stiffness of the torsionally soft element.
In einer Ausführungsform ist in Gießrichtung betrachtet das Lager am oberen Ende und die Verstelleinrichtung am unteren Ende des Strangführungselements angeordnet.In one embodiment, viewed in the casting direction, the bearing is arranged at the upper end and the adjustment device is arranged at the lower end of the strand guide element.
In einer weiteren Ausführungsform erfolgt das feste Einspannen mittels einer formschlüssigen oder einer reibschlüssigen Verbindung; z.B. ist das erste Ende und/oder das zweite Ende des stabförmigen Bauteils formschlüssig oder reibschlüssig mit dem Innenrahmen oder dem Außenrahmen verbunden. Sowohl eine formschlüssige als auch eine reibschlüssige Verbindung sind gut dazu geeignet, einen stabförmigen Bauteil einzuspannen.In a further embodiment, the fixed clamping takes place by means of a form-fitting or a friction-fitting connection; e.g. the first end and/or the second end of the rod-shaped component is positively or frictionally connected to the inner frame or the outer frame. Both a form-fitting and a friction-fitting connection are well suited for clamping a rod-shaped component.
In einer weiteren vorteilhaften Ausführungsform weist die Verstelleinrichtung ein erstes Ende, wenigstens einen Biegestab und ein zweites Ende auf, wobei das erste Ende der Verstelleinrichtung in dem Innenrahmen und das zweite Ende der Verstelleinrichtung in dem Außenrahmen fest eingespannt ist und der Biegestab die Biegebeanspruchung bei der Bewegung des Innenrahmens gegenüber dem Außenrahmen aufnimmt. Mittels dieser Ausführungsform wird ein völlig spielfreies Strangführungselement geschaffen; außerdem ist es möglich, eine lagerseitige und eine verstelleinrichtungsseitige Dickenverstellung vorzunehmen.In a further advantageous embodiment, the adjusting device has a first end, at least one bending rod and a second end, with the first end of the adjusting device being firmly clamped in the inner frame and the second end of the adjusting device being firmly clamped in the outer frame, and the bending rod absorbing the bending stress during movement of the inner frame relative to the outer frame. By means of this embodiment, a strand guide element that is completely free of play is created; it is also possible to carry out a thickness adjustment on the bearing side and on the adjusting device side.
In einer einfachen Ausführungsform ist die Verstelleinrichtung als ein Druckmittelzylinder ausgeführt, wobei dessen Kolbenstange als Biegestab ausgeführt ist. Dadurch lässt sich auf sehr einfache und robuste Art und Weise eine Verstelleinrichtung mit Biegestab realisieren, wobei es belanglos ist, ob der Kolben und der Biegestab als ein Bauteil oder - so wie üblich - als zwei einzelne aber miteinander verbundene Bauteile ausgeführt sind.In a simple embodiment, the adjusting device is designed as a pressure medium cylinder, the piston rod of which is designed as a flexible rod. As a result, an adjustment device with a flexible rod can be implemented in a very simple and robust manner, it being irrelevant whether the piston and the flexible rod are designed as one component or—as is usual—as two individual but interconnected components.
Für eine hohe Einstellgenauigkeit des Strangführungselements ist es vorteilhaft, die Verstelleinrichtung mit einer Messeinrichtung zur Messung des Abstands zwischen Innenrahmen und Außenrahmen auszubilden. Weiters ist es vorteilhaft, die Messeinrichtung in den Druckmittelzylinder zu integrieren bzw. direkt am Kolben oder der Zugstange (zentral) zu messen.For a high adjustment accuracy of the strand guide element, it is advantageous to form the adjusting device with a measuring device for measuring the distance between the inner frame and the outer frame. It is also advantageous to integrate the measuring device into the pressure medium cylinder or to measure directly on the piston or the tie rod (centrally).
In einer einfachen Ausführungsform ist zwischen dem stabförmigen Bauteil und dem Innen- oder Außenrahmen eine Beilage oder ein Betätigungselement zur Anpassung des Strangführungselements an unterschiedliche Gießdicken angeordnet.In a simple embodiment, a shim or an actuating element for adapting the strand-guiding element to different cast thicknesses is arranged between the rod-shaped component and the inner or outer frame.
Besonders vorteilhaft ist es, das erfindungsgemäße Strangführungselement in einer Stranggießmaschine zur Herstellung eines Stranges, vorzugsweise mit einem Querschnitt für Brammen oder Dünnbrammen, aus Stahl zu verwenden.It is particularly advantageous to use the strand-guiding element according to the invention in a continuous casting machine for producing a strand, preferably with a cross-section for slabs or thin slabs, from steel.
Weiters ist es vorteilhaft, das Strangführungselement gleichzeitig als ein Biegesegment zur Umlenkung des Stranges von einer vertikalen in eine gebogene Richtung zu verwenden, wobei bei dieser Verwendung mindestens eine Strangführungsrolle als angetriebene Rolle ausgeführt ist.Furthermore, it is advantageous to use the strand-guiding element at the same time as a bending segment for deflecting the strand from a vertical to a curved direction, with at least one strand-guiding roller being designed as a driven roller for this use.
Auch kann das Strangführungselement an beliebiger anderer Position in der Strangführung eingesetzt werden, wo eine größere Dickenreduktion stattfinden soll.The strand guide element can also be used at any other position in the strand guide where a greater reduction in thickness is to take place.
