Description

.Die Erfindung bezieht sich auf eine Stranggießanlage, insbesondere Horizontal-Stranggießanlage mit einer auf einem Gestell abgestützten Abziehvorrichtung, die mindestens eine von einem Motor antreibbare Antriebsrolle und minde- stens eine mittels einer Anpreßvorrichtung gegen diese drückbare Gegendruckrolle aufweist, wobei die Achsen der beiden Rollen vorzugsweise parallel verlaufen.The invention relates to a continuous casting installation, in particular a horizontal continuous casting installation with a pull-off device supported on a frame, which has at least one drive roller which can be driven by a motor and at least one counter-pressure roller which can be pressed against it by means of a pressing device, the axes of the two rollers preferably run in parallel.

Bei einer bekannten derartigen Stranggießanlage verläuft die Welle der Antriebsrolle in horizontaler Richtung und ist direkt im Gestell gelagert. Die Gegendruckrolle ist dabei mittels der im Gestell gehaltenen Anpreßvorrichtung in Richtung zur Welle der Antriebsrolle bzw. von dieser weg bewegbar.In a known continuous casting installation of this type, the shaft of the drive roller runs in the horizontal direction and is mounted directly in the frame. The counter-pressure roller can be moved in the direction of the shaft of the drive roller or away from it by means of the pressing device held in the frame.

Es hat sich gezeigt, daß insbesondere bei im Querschnitt quadratischen oder rechteckigen Strängen mit größeren Querschnitten, z.B. über 25 cm2, der Einfluß der Schwerkraft bei der oben beschriebenen Anordnung der Rollen einen störenden Einfluß ausübt. Außerdem ergeben sich beim Abziehen eines einen viereckigen Querschnitt aufweisenden Stranges mit einer in der Horizontalebene liegenden Fläche sehr ungünstige Verhältnisse im Hinblick auf die Kühlung. Dies wirkt sich in einem ungünstigen Ablauf der Erstarrung des Inneren des Stranges aus, wodurch es zu über den Querschnitt verteilten Unterschieden im Gefüge und zur Ausbildung von vermehrten Seigerungen kommt.It has been shown that, in particular in the case of strands which are square or rectangular in cross section and have larger cross sections, for example more than 25 cm 2 , the influence of gravity has a disruptive effect in the arrangement of the rollers described above. In addition, when pulling off a strand having a square cross section with a surface lying in the horizontal plane, very unfavorable conditions arise with regard to the cooling. This results in an unfavorable process of solidification of the interior of the strand, which leads to differences in the structure distributed over the cross section and to the formation of increased segregations.

Ziel der Erfindung ist es, eine Stranggleßanlage der eingangs erwähnten Art vorzuschlagen, die ein optimales Abziehen von Strängen unter besonders günstigen metallurgischen Bedingungen mit unterschiedlichen Querschnitten ermöglicht.The aim of the invention is to propose a continuous casting machine of the type mentioned at the outset, which enables the optimal removal of strands under particularly favorable metallurgical conditions with different cross sections.

Erfindungsgemäß wird daher vorgeschlagen, daß die Antriebsrolle(n) bzw. deren Antriebswelle(n) und die Anpreßvorrichtung(en) samt der (den) Gegendruckrolle(n) in einer gegenüber dem Gestell um die Längsachse des Stranges verdreh- und feststellbaren Halterung gehalten sind. Damit ist es möglich, z.B. einen Strang mit quadratischem oder rechteckigem Querschnitt in einer Lage abzuziehen, in der die Diagonale seines Querschnittes vertikal verläuft, wogegen zum Abziehen von Strängen mit rundem Querschnitt die Welle der Antriebsrolle in eine horizontale Lage gebracht werden kann. Dadurch kann der Strangabzug immer so angeordnet werden, daß der noch nicht vollkommen erstarrte Strang eine optimale Steifigkeit aufweist.According to the invention it is therefore proposed that the drive roller (s) or their drive shaft (s) and the pressing device device (s) together with the counter-pressure roller (s) are held in a holder that can be rotated and locked relative to the frame around the longitudinal axis of the strand. This makes it possible, for example, to pull off a strand with a square or rectangular cross section in a position in which the diagonal of its cross section runs vertically, whereas for pulling off strands with a round cross section the shaft of the drive roller can be brought into a horizontal position. As a result, the strand withdrawal can always be arranged in such a way that the strand which has not yet completely solidified has optimum rigidity.

Erfindungsgemäß weisen die Antriebsrolle(n) und gegebenenfalls die Gegendruckrolle(n) ein dem Strangprofil entsprechendes Gegenprofil auf. Dadurch kann auch bei einem Strang, der eine Zunderschicht aufweist, besonders einfach eine exakte Führung erreicht werden.According to the invention, the drive roller (s) and optionally the counterpressure roller (s) have a counter profile corresponding to the extruded profile. As a result, exact guidance can be achieved particularly easily even in the case of a strand which has a scale layer.

Es kann nach einem weiteren Merkmal der Erfindung die verdreh- und feststellbare Halterung zumindest zwei einander gegenüberliegende Stütz- und Führungsrollen aufweisen. Damit kann auch bei Strängen mit höherem Gewicht eine exakte Führung und ein exakter Abzug erreicht werden.According to a further feature of the invention, the rotatable and lockable holder can have at least two opposing support and guide rollers. In this way, exact guidance and an exact withdrawal can be achieved even with strands with a higher weight.

Nach einem weiteren Merkmal der Erfindung Ist vorgesehen, daß die Halterung mittels eines oder mehrerer in Ausnehmungen eines mit dem Gestell fest verbundenen Stellringes einsetzbarer Bolzen in bestimmten Stellungen festlegbar ist. Damit ergibt sich eine sehr einfache Konstruktion für eine besonders exakte Feststelleinrichtung.According to a further feature of the invention, it is provided that the holder can be fixed in certain positions by means of one or more bolts which can be inserted into recesses of an adjusting ring which is firmly connected to the frame. This results in a very simple construction for a particularly precise locking device.

Eine sehr einfache Konstruktion ergibt sich, wenn die Halterung als Zylinder ausgebildet ist, der auf im Gestell gelagerten Rollen aufliegt, von denen vorzugsweise mindestens eine antreibbar ist. Außerdem wird dadurch auch eine sehr einfache Handhabung beim Umstellen der Abziehvorrichtung ermöglicht.A very simple construction results if the holder is designed as a cylinder which rests on rollers mounted in the frame, of which at least one can preferably be driven. In addition, this also enables very simple handling when changing the pulling device.

Bei einer besonders bevorzugten Ausführungsform der Erfindung Ist vorgesehen, daß die Halterung als Doppelmantel, insbesondere durch zwei konzentrisch liegende Rohre gebildet ist, welche an ihren Enden durch Stirnringe dicht abgeschlossen sind, und eine Zu- und Abfuhr für ein Kühlmedium aufweisen, wobei vorzugsweise der Antrieb für die Antriebsrolle und die Anpreßvorrichtung für die Gegendruckrolle an der Außenseite der Halterung angeordnet sind. Damit wird eine weitgehend vor der Hitzestrahlung des abzuziehenden Stranges geschützte Anordnung des Antriebes der Antriebsrolle, der zumeist auch eine relativ empfindliche elektronische Steuerung umfaßt, und der Anpreßvorrichtung der Gegendruckrolle erreicht, wodurch mit einem wesentlich einfacheren Aufbau dieser Teile das Auslangen gefunden wird und sich überdies deren Reparaturanfälligkeit vermindert. Wobei gleichzeitig auch eine weitere Kühlung der an sich gekühlten Abzugsrollen,aber auch der Achsen, erreicht wird.In a particularly preferred embodiment of the invention, it is provided that the holder is formed as a double jacket, in particular by two concentrically located tubes, which are sealed at their ends by end rings, and have an inlet and outlet for a cooling medium, preferably the drive for the drive roller and the pressing device for the counter pressure roller are arranged on the outside of the holder. Thus, a largely protected from the heat radiation of the strand to be removed arrangement of the drive of the drive roller, which usually also includes a relatively sensitive electronic control, and the pressing device of the counter-pressure roller is achieved, whereby with a much simpler construction of these parts, the sufficiency is found and, moreover, theirs Reduced susceptibility to repairs. At the same time, further cooling of the puller rollers, which are cooled per se, but also of the axles, is achieved.

Die Erfindung wird nun an Hand der Zeichnung näher erläutert:

  • Dabei zeigen Fig. 1 eine Seitenansicht einer erfindungsgemäßen Abziehvorrichtung und Fig. 2 eine Draufsicht auf die Abziehvorrichtung gemäß Fig. 1.
The invention will now be explained in more detail with reference to the drawing:
  • 1 shows a side view of a pull-off device according to the invention and FIG. 2 shows a top view of the pull-off device according to FIG. 1.

In dem Gerüst 1 sind Rollen 2,2' gelagert, von denen die Rollen 2 lediglich in den hochgezogenen Randbereichen 3 des Gerüstes 1, die Rollen 2' dagegen im mittleren Bereich 4 des Gerüstes 1 angeordnet sind, wobei der mittlere Bereich 4 des Gerüstes 1, wie durch die strichlierten Linien in Fig. 1 angedeutet, tiefer als die Randbereiche 3 verläuft, die überdies auch breiter als der mittlere Bereich 4 sind. In diesem mittleren Bereich 4 liegt die Halterung 5 auf drei Rollen 2' auf, wogegen sie in den Randb'ereichen 3 des Gerüstes 1 auf fünf Rollen 2 aufliegt, von denen zumindest eine antreibbar ist.Rollers 2, 2 'are mounted in the frame 1, of which the rollers 2 are arranged only in the raised edge regions 3 of the frame 1, while the rollers 2' are arranged in the middle region 4 of the frame 1, the middle region 4 of the frame 1 , as indicated by the dashed lines in FIG. 1, runs deeper than the edge regions 3, which are also wider than the central region 4. In this central region 4, the holder 5 rests on three rollers 2 ', whereas it rests on the peripheral regions 3 of the frame 1 on five rollers 2, at least one of which can be driven.

Die Halterung 5 ist durch zwei konzentrische Rohre 6 und 7 gebildet, die an ihren Stirnseiten mittels Stirnringe 8,8' miteinander dicht verbunden sind und die Kühlzone 10 bilden, wobei der Stirnring 8' über das äußere Rohr 6 vorsteht und einen Flansch bildet. In diesem Flansch sind ebenso wie in dem als Stellring 9 dienenden Teil des Gestelles 1 Ausnehmungen 11 angeordnet, die in bestimmten gegenseitigen Winkellagen der beiden Flansche miteinander fluchten, sodaß ein Sichern dieser Lagen durch Einsetzen von Schraubenbolzen 12 oder dergleichen möglich ist.The holder 5 is formed by two concentric tubes 6 and 7, which are tightly connected at their end faces by means of end rings 8, 8 'and form the cooling zone 10, the end ring 8' projecting beyond the outer tube 6 and forming a flange. In this flange, as well as in the part of the frame 1 serving as the collar 9, recesses 11 are arranged which are aligned with each other in certain mutual angular positions of the two flanges, so that securing these positions is possible by inserting screw bolts 12 or the like.

Das äußere Rohr 6 der Halterung 5 ist von zwei Stutzen 13,14 im wesentlichen radial durchsetzt, die eine Zu- und Abfuhr eines das Innere des von den Rohren 6 und 7 und den Stirnringen 8,8' bestimmten Raumes durchströmenden Kühlmediums erlauben, das z.B. über nicht dargestellte Schläuche zu- bzw. abströmt.The outer tube 6 of the holder 5 is penetrated essentially radially by two connecting pieces 13, 14, which allow a cooling medium flowing through the interior of the space defined by the tubes 6 and 7 and the end rings 8, 8 'to be supplied and removed, e.g. flows in or out via hoses, not shown.

In der Halterung 5 ist. die Welle 15 gelagert, die drehfest mit einer Antriebsrolle 16 verbunden Ist und entlang einer Sehne verläuft. Die Lager der Welle 15 können in mit den Rohren 6,7 dicht verschweißten Blöcken angeordnet werden. Weiters ragt in das Innere der Halterung 5 eine einen gabelförmigen Kopf 17 tragende Kolbenstange 18 einer durch eine Kolben-Zylinderanordnung gebildeten Anpreßvorrichtung 19 hinein. Der Kopf 17 dieser die Rohre 6,7 radial durchsetzenden Kolbenstange 18 hält eine parallel zur Welle 15 verlaufende Achse 20, auf der eine Gegendruckrolle 21 gelagert ist.In the holder 5 is. the shaft 15 is mounted, which is rotatably connected to a drive roller 16 and runs along a chord. The bearings of the shaft 15 can be arranged in blocks tightly welded to the tubes 6, 7. A piston rod 18 carrying a fork-shaped head 17 of a pressing device 19 formed by a piston-cylinder arrangement also projects into the interior of the holder 5. The head 17 of this piston rod 18, which radially penetrates the tubes 6, 7, holds an axis 20 which runs parallel to the shaft 15 and on which a counterpressure roller 21 is mounted.

Die Mantelflächen der Antriebs- und der Gegendruckrolle 16 bzw. 21 sind mit umlaufenden Nuten 22 versehen, welche dem Profil des abzuziehenden Stranges 23 entsprechen.The lateral surfaces of the drive and counter pressure rollers 16 and 21 are provided with circumferential grooves 22 which correspond to the profile of the strand 23 to be drawn off.

Die Anpreßvorrichtung 19 ist an einer an der Außenseite des Rohres 6 der Halterung 5 befestigten Konsole 24 angeordnet und somit gegen die Wärmestrahlung des Stranges 23 durch die von einem Kühlmedium durchströmte Halterung 5 abgeschirmt. In der Halterung sind weiters verstellbare Stütz- und Führungsrollen 26 angeordnet.The pressing device 19 is arranged on a bracket 24 fastened to the outside of the tube 6 of the holder 5 and thus against the heat radiation of the strand 23 the holder 5, through which a cooling medium flows, is shielded. Adjustable support and guide rollers 26 are also arranged in the holder.

Dadurch, daß der mittlere Bereich 4 des Gerüstes 1 niedriger und auch schmäler als die Randbereiche 3 ist, wird genügend Platz geschaffen, um die Halterung 5 nach beiden Seiten um 45° aus der in Fig. 1 dargestellten Lage verschwenken zu können und andererseits durch die hochgezogenen Randbereiche 3 eine sehr gute und stabile Lagerung der Halterung 5 erreicht.Characterized in that the central region 4 of the scaffold 1 is lower and also narrower than the edge regions 3, sufficient space is created to be able to pivot the holder 5 to both sides by 45 ° from the position shown in FIG. 1 and on the other hand by the raised edge regions 3 achieved a very good and stable mounting of the bracket 5.

Die dargestellte Lage der'Halterung 5 eignet sich besonders für Stränge mit quadratischem Querschnitt, da sich in dieser Lage der Einfluß der Schwerkraft auf die Pressung des Stranges beim Abziehen besonders gut beherrschen läßt und sich eine weitgehend gleichmäßige Abkühlung an allen Mantelflächen des Stranges 23 ergibt.The position of the 'holder 5 shown is particularly suitable for strands with a square cross-section, since in this position the influence of gravity on the pressure of the strand during pulling off can be controlled particularly well and there is a largely uniform cooling on all lateral surfaces of the strand 23.

Demgegenüber ist bei Strängen mit rundem Querschnitt eine unter dem Strang liegende, horizontal verlaufende Welle 15 der Antriebsrolle 16 vorteilhafter, wobei diese Lage der Welle 15 einfach durch Entfernen der Bolzen 12, Verdrehen der Halterung 5 im Gegenuhrzeigersinn um 45° und Einsetzen der Bolzen 12 zur Sicherung dieser Lage, erreicht werden kann. DasIn contrast, in strands with a round cross-section, a horizontally extending shaft 15 of the drive roller 16 lying beneath the strand is more advantageous, this position of the shaft 15 simply by removing the bolts 12, rotating the holder 5 counterclockwise by 45 ° and inserting the bolts 12 Securing this location can be achieved. The

Verdrehen der Halterung 5, kann dabei mittels antreibbarer Rollen 2 oder 2' oder anderer Einrichtungen, wie z.B. am Gerüst 1 und an der Halterung 5 angreifende Zylinder-Kolbenanordnungen erfolgen.Rotation of the bracket 5 can be driven by rollers 2 or 2 'or other devices such as cylinder-piston arrangements acting on the frame 1 and on the holder 5.

Selbstverständlich Ist es auch möglich, das Gerüst 1 zweiteilig auszubilden und zwischen diesen Teilen genügend Platz zu lassen, um ein Einschwenken des Antriebes 25 oder der Anpreßvorrichtung 19 in diesen Zwischenraum zu ermöglichen. Bei einer solchen Anordnung Ist dann eine Verschwenkung der Halterung 5 bis zu 360° möglich, wenn die Zuleitungen zu den Stutzen 13,14, die Anpreßvorrichtung 19 und der Antrieb 25 entsprechend dimensioniert sind.Of course, it is also possible to design the scaffold 1 in two parts and to leave enough space between these parts to allow the drive 25 or the pressing device 19 to pivot into this intermediate space. With such an arrangement, pivoting of the holder 5 up to 360 ° is possible if the feed lines to the connecting pieces 13, 14, the pressing device 19 and the drive 25 are dimensioned accordingly.
