Description

Die Erfindung betrifft eine Auszieheinrichtung im horizontalen Teil einer Stranggießanlage mit einer parallel zum Strang vor- bzw. zurückbewegbaren Klemmvorrichtung, die durch Zugmittel zumindest in Stranglaufrichtung bewegbar ist. Währen bei Vertikalstranggießanlagen das Ausfördern des Gußstranges teils durch die Schwerkraft und teils durch die Vertikalstranggießkokille unterstützt wird, erfolgt das Ausfördern des Gußstranges bei Horizontalstranggießanlagen bzw. im horizontalen Teil einer Bogenstranggießanlage durch Auszieheinrichtungen. Zum Einsatz kommen hier Rollen- oder Klemmbackenausziehmaschinen.The invention relates to a pull-out device in the horizontal part a continuous caster with a feed or parallel to the strand retractable clamping device, at least in by traction means Strand running direction is movable. During vertical continuous casting machines the casting of the cast strand partly by gravity and partly this is supported by the vertical continuous casting mold Conveying the cast strand in horizontal continuous casting plants or in horizontal part of a continuous caster Extractors. Rolls or are used here Jaw extractors.

Aus der Schrift DE 29 37 423 A1 ist beispielsweise ein Ziehgerüst für eine kontinuierliche Horizontalstranggießanlage bekannt, bei der Antriebsrollen in einer drehbaren Fassung fliegend befestigt sind, bei der Schwinghebel mit den Antriebsrollen in einer zur Drehachse der Fassung senkrechten Ebene angeordnet sind und die Enden der Hebel unter Bildung eines gechlossenen Rahmens aufeinanderfolgend miteinander verbunden sind. From the document DE 29 37 423 A1, for example, a drawing frame for a continuous horizontal caster known Drive rollers in a rotatable socket are attached on the fly, with the rocker arm with the drive rollers in one to the axis of rotation the frame vertical plane are arranged and the ends of the levers successively forming a closed frame are interconnected.

Abgesehen von dem allen Rollenausziehmaschinen anhaftenden Nachteil der hohen Flächenpressung zwischen den Ausziehrollen und dem Strang, weist das hier beschriebene Ziehgerüst neben seinem komplizierten Aufbau einen relativ großen Bauraum unmittelbar um den Strang auf.Apart from the disadvantage of all roller extractors high surface pressure between the pull-out rollers and the strand the scaffolding described here in addition to its complicated structure relatively large space directly around the strand.

Aus der Schrift DE 32 06 501 C1 ist ein Verfahren zum Horizontalstranggießen und die dazu vorgesehene Auszieheinrichtung bekannt, bei der eine Klemmvorrichtung in einer zur Strangachse parallel laufenden Führung auf einem Träger angeordnet ist, wobei der Träger durch eine an ihm unmittelbar angeschlossene Kolbenzylindereinheit bewegbar ist. Der Träger ist als Wagen ausgestaltet, dessen Räder auf als Schienen ausgeführte Führungen laufen. Zum Schutz gegen Schmutz sind diese relativ genauen Führungen durch Abdeckungen geschützt. Diese wartungsintensive una eine Reihe von konstruktiv aufwendigen Elementen aufweisende Auszieheinrichtung ist darüber hinaus mit dem Nachteil behaftet, daß über die Führungseinrichtung Kräfte in den Strang eingeleitet werden.From the document DE 32 06 501 C1 is a method for Horizontal continuous casting and the intended pull-out device is known in which a clamping device in a parallel to the strand axis running guide is arranged on a carrier, the carrier by a piston-cylinder unit directly connected to it is movable. The carrier is designed as a carriage, the wheels of which Guides designed as rails run. To protect against dirt these relatively accurate guides are protected by covers. This maintenance-intensive and a series of structurally complex Pull-out device with elements is also with the Disadvantageous that forces in the strand via the guide device be initiated.

Die Erfindung hat sich das Ziel gesetzt, eine Auszieheinrichtung im horizontalen Teil einer Stranggießanlage zu schaffen, die konstruktiv einfache sowie wartungsarme Elemente besitzt und bei der bei einem Minimum von Bauraum am Strang auf diesem über die Klemmbacken außer den erforderlichen Druckkräften ausschließlich Zugkräfte wirken.The invention has set itself the goal of an extractor in the horizontal part of a Continuous caster to create the structurally simple as well has low-maintenance elements and with a minimum of installation space on the strand on this over the jaws except the required Compressive forces only act as tensile forces.

Die Erfindung erreicht dieses Ziel bei einer Auszieheinrichtung der bekannten Art durch die kennzeichnenden Merkmale des Anspruchs 1.
Hierzu wird eine Klemmvorrichtung vorgeschlagen, die einen Bügel aufweist, der ein Gelenk besitzt und dessen Bügelarme durch eine Zug- oder Druckeinrichtung Klemmbacken an den Strang oder von diesem wegbewegt. An den Klemmbacken sind Zugmittel vorgesehen, die parallel zur Strangachse anderenends unmittelbar am Fundament der Horizontalstranggießanlage schwenkbar befestigt sind. Durch diese unmittelbare Befestigung am Fundament ist nicht nur ein konstruktiv äußerst einfacher Aufbau gegeben, es ist auch gewährleistet, daß auf die Klemmbacken ausschließlich Zugkräfte wirken.The invention achieves this goal in a pull-out device of the known type by the characterizing features of claim 1.
For this purpose, a clamping device is proposed which has a bracket which has a joint and whose bracket arms move clamping jaws to or from the strand by means of a pulling or pushing device. Traction means are provided on the clamping jaws, which are pivotally attached at the other ends directly to the foundation of the horizontal continuous caster, parallel to the strand axis. This direct attachment to the foundation not only provides an extremely simple construction, it also ensures that only tensile forces act on the clamping jaws.

Während der Klemm- und Ziehphase sind Führungselemente vorgesehen, die beispielsweise durch Zugfedern nachgiebig ausgestaltet sind und ein behinderungsfreies Führen der Klemmbacken zulassen. Um den Klemmbügel mit seinen Klemmbacken außerhalb der Klemmphase in seiner Position parallel zur Hauptstranggießachse zu halten, sind diese Führungselemente in Form von Zug- oder Druckelementen so gestaltet, daß die Klemmbacken für die nächste Druck- und Zugphase exakt positionierbar sind.During the clamping and pulling phase, guide elements are provided are designed to be flexible, for example by tension springs, and a Allow the jaws to move freely. Around the clamp with its clamping jaws in position outside the clamping phase they must be kept parallel to the main continuous casting axis Guide elements in the form of tension or compression elements designed so that the clamping jaws for the next pushing and pulling phase exactly are positionable.

Ausziehmaschinen mit Backenantrieben arbeiten üblicherweise so, daß zur Bildung der Schale in einem bestimmten Zyklus mit der Strangbewegung diskontinuierlich gezogen und ggfs. sogar zurückgestoßen wird. Da die Gesamtziehstrecke begrenzt ist, werden üblicherweise mindestens zwei Backenantriebe eingesetzt. Der Zyklus wird von den Zylindern der gerade geklemmten Backen durchgeführt. Kurz vor Ende des Erreichens der Maximalziehstrecke wird innerhalb eines Zyklus die Ziehbewegung auf den zweiten Backenantrieb übergeben. Der außer Betrieb befindliche Zylinder löst die Klemmbacken und geht für die nächste übergabe in seine Ausgangsstellung, bis er wiederum das Klemmen und Ziehen übernimmt.Pullers with jaw drives usually work in such a way that Formation of the shell in a certain cycle with the strand movement discontinuously pulled and possibly even pushed back. Since the Total drawing distance is limited, usually at least two Jaw drives used. The cycle is straight from the cylinders clamped jaws performed. Shortly before reaching the The maximum pulling distance is the pulling movement to the hand over the second jaw drive. The cylinder out of service releases the jaws and goes into his for the next handover Starting position until it takes over the clamping and pulling again.

Die vorgeschlagene Auszieheinrichtung mit dem einfachen Klemmbügel und der am Fundament befestigten Zugeinrichtung erlaubt eine Anordnung beider Klemmvorrichtungen mit einem Minimum an Bauraum. The proposed pull-out device with the simple clamp and the pulling device attached to the foundation allows an arrangement both clamping devices with a minimum of space.

So können die Zugeinrichtungen in einem weiten Bereich parallel zueinander und die Klemmbacken selber unter Berücksichtigung des maximalen Fahrweges unmittelbar hintereinander angeordnet werden.This means that the traction devices can be parallel in a wide range to each other and the jaws themselves, taking into account the maximum travel path can be arranged directly one behind the other.

Durch die kardanische Aufhängung gelangen keinerlei Drehmomente oder im rechten Winkel zur Zentralachse wirkende Kräfte auf den Strang. Damit können die erforderlichen Klemmkräfte sowie Zugkräfte feinstdosiert und so niedrig wie möglich eingestellt werden.Due to the gimbal suspension no torque or in forces acting on the strand at right angles to the central axis. In order to the required clamping forces and tensile forces can be precisely metered and be set as low as possible.

Durch den Einsatz nur weniger jeweils eine eigene Elastizität aufweisender Stahl- und Maschinenbauteile wird die Gesamtkonstruktion steifer mit der positiven Folge, daß die Geschwindigkeits- und Beschleunigungsprofile von den Stellgliedern mit noher Präzision auf den Strang übertragen werden.By using only a few elasticities each steel and machine components will be the overall construction stiffer with the positive consequence that the speed and Acceleration profiles from the actuators with no precision be transferred to the strand.
