Definitions
- the invention relates to a device for the horizontal continuous casting of metals according to the preamble of claim 1.
- Such a device is known in principle from DAS 12 92 791.
- the pivot axis is arranged in the plane between the drive rollers, so that the device on the pouring side can be raised towards the end of the casting in order to maintain the necessary metallostatic pressure in the mold when the casting level drops.
- a device for the horizontal continuous casting of metals in which a separation of the distributor and the mold is achieved by shut-off devices which close the distributor outlet opening and at the same time close the mold inlet at the end of casting or a fault. Since the distributor and the mold can be separated from one another between the shut-off devices, the distributor can be emptied with the residual melt, including any slag, by tipping over at the end of pouring or in the event of a malfunction, without having to wait for the solidification of the melt in the mold.
- DE 27 10 680 C2 discloses a device for casting strands, in particular precious metals, which makes it possible to work in the holding furnace or the mold without residue from the melt.
- the holding furnace, a cooler with mold and the extrusion device are arranged on a common frame that can be swiveled up to 180 °.
- the cooler and the mold are attached to a holding device that can be folded away from the holding furnace.
- the invention is therefore based on the object of developing a device according to the preamble of claim 1 and of improving and simplifying the accessibility of the system in the event of faults.
- the object is achieved according to the invention in a device for the horizontal continuous casting of metals, consisting of a pouring device, a mold and a strand transport device, which are arranged on a bridge construction which can be pivoted about a horizontal axis lying transversely to the casting direction, in that the axis forming the pivot point is arranged below the pouring opening designed as a holding furnace inside the bridge construction and the holding furnace, the mold with a possibly subsequent secondary cooling section and the strand transport device can be swung out in the vertical direction from the casting position in the vertical direction by means of a hydraulic cylinder acting on the free end of the bridge construction in the casting direction in front of the axis .
- the drawing shows a device for the horizontal continuous casting of metals in a side view.
- the device consists of a holding furnace 1, to the side of which a horizontal mold 2 is connected and which is followed by a secondary cooling section 3. As seen in the casting direction, another follows Strand transport device 4 with two pairs of drive rollers 5.
- the holding furnace 1, the mold 2, the secondary cooling section 3 and the strand transport device 4 are arranged according to the invention on a common bridge construction 6.
- a strand 7 produced in this device can be divided into strand sections in a subsequent separating device 8, which, depending on the strand format, is designed as a saw or scissors.
- the strand sections are picked up by a roller table 9 and transported further.
- the bridge structure 6 is pivotally mounted about the axis 10 placed under the holding furnace 1. From the casting position shown in the drawing, the device (1 to 4) including the bridge structure 6 is actuated in a vertical direction from the casting position by actuating a hydraulic cylinder 11, which engages at the free end of the bridge structure 6 in the casting direction in front of the axis 10 at the articulation point 12 swing out at the top.
- the hydraulic cylinder 11 is fastened with its foot end 14 to a supporting frame 13 on which the bridge structure 6 rests during the casting process.
- the support frame 13, the separating device 8 and the roller table 9 are attached to a plate 15.
- the advantages of the device according to the invention lie on the one hand in the very compact design and on the other hand in the fact that the regular separating device for the strand can also be used as an emergency separating device in order to bring about an immediate disconnection of the strand and pivot the pouring device for emergency emptying via the holding oven, so that damage to the molds is avoided. This advantage is particularly noticeable in the very expensive tubular molds.

Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum horizontalen Stranggießen von Metallen gemäß Gattungsbegriff des Anspruchs 1.The invention relates to a device for the horizontal continuous casting of metals according to the preamble of claim 1.
Eine derartige Einrichtung ist im Prinzip aus der DAS 12 92 791 bekannt. Hier ist die Schwenkachse in der Ebene zwischen den Treibwalzen angeordnet, so daß gegen Gießende die Einrichtung an der Eingießseite angehoben werden kann, um den notwendigen metallostatischen Druck in der Kokille bei absinkendem Gießspiegel aufrechtzuerhalten.Such a device is known in principle from DAS 12 92 791. Here, the pivot axis is arranged in the plane between the drive rollers, so that the device on the pouring side can be raised towards the end of the casting in order to maintain the necessary metallostatic pressure in the mold when the casting level drops.
Aus dem DE-GM82 01 246 ist eine Einrichtung zum horizontalen Stranggießen von Metallen bekannt, bei der eine Trennung von Verteiler und Kokille durch Absperrorgane erreicht wird, die die Verteilerauslauföffnung und gleichzeitig den Kokilleneingang bei Gießende oder einer Störung schließen. Da Verteiler und Kokille zwischen den Absperrorganen voneinander trennbar sind, kann bei Gießende oder einer Störung der Verteiler mit der Restschmelze einschließlich etwaiger Schlacke durch Kippen entleert werden, ohne die Erstarrung der Schmelze in der Kokille abwarten zu müssen.From DE-GM82 01 246 a device for the horizontal continuous casting of metals is known, in which a separation of the distributor and the mold is achieved by shut-off devices which close the distributor outlet opening and at the same time close the mold inlet at the end of casting or a fault. Since the distributor and the mold can be separated from one another between the shut-off devices, the distributor can be emptied with the residual melt, including any slag, by tipping over at the end of pouring or in the event of a malfunction, without having to wait for the solidification of the melt in the mold.
Schließlich ist aus der DE 27 10 680 C2 eine Vorrichtung zum Gießen von Strängen, insbesondere an Edelmetallen, bekannt, die es ermöglicht ohne Rückstände von Schmelze im Warmhalteofen oder der Kokille zu arbeiten. Hierzu sind der Warmhalteofen, ein Kühler mit Kokille und die Strangzieheinrichtung auf einem gemeinsamen bis zu 180 ° schwenkbaren Rahmen angeordnet. Der Kühler und die Kokille sind an einer Aufnahmevorrichtung befestigt, die vom Warmhalteofen wegklappbar ist.Finally, DE 27 10 680 C2 discloses a device for casting strands, in particular precious metals, which makes it possible to work in the holding furnace or the mold without residue from the melt. For this purpose, the holding furnace, a cooler with mold and the extrusion device are arranged on a common frame that can be swiveled up to 180 °. The cooler and the mold are attached to a holding device that can be folded away from the holding furnace.
Es hat sich jedoch gezeigt, daß diese Ausführung sehr aufwendig ist und in Störfällen, die in der Kokille oder durch Strangschalendurchbrüche unmittelbar hinter der Kokille auftreten, nicht zum gewünschten Erfolg führt.However, it has been shown that this embodiment is very complex and does not lead to the desired success in the event of faults which occur in the mold or through strand shell breakthroughs directly behind the mold.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung gemäß Gattungsbegriff des Anspruches 1 weiterzubilden und eine Verbesserung und Vereinfachung in der Zugänglichkeit der Anlage bei Störfällen zu erreichen. Die Aufgabe wird bei einer Einrichtung zum horizontalen Stranggießen von Metallen, bestehend aus einer Eingießvorrichtung, einer Kokille und einer Strangtransportvorrichtung, die auf einer um eine horizontale, quer zur Gießrichtung liegende Achse schwenkbaren Brückenkonstruktion angeordnet sind, erfindungsgemäß dadurch gelöst, daß die den Schwenkpunkt bildende Achse unterhalb der als Warmhalteofen ausgebildeten Eingießöffnung innerhalb der Brückenkonstruktion angeordnet ist und der Warmhalteofen, die Kokille mit einer sich eventuell anschließenden Sekundärkühlstrecke und die Strangtransportvorrichtung mittels eines am freien Ende der Brückenkonstruktion in Gießrichtung vor der Achse angreifenden Hydraulikzylinders in vertikaler Richtung aus der Gießposition nach oben ausschwenkbar ist.The invention is therefore based on the object of developing a device according to the preamble of claim 1 and of improving and simplifying the accessibility of the system in the event of faults. The object is achieved according to the invention in a device for the horizontal continuous casting of metals, consisting of a pouring device, a mold and a strand transport device, which are arranged on a bridge construction which can be pivoted about a horizontal axis lying transversely to the casting direction, in that the axis forming the pivot point is arranged below the pouring opening designed as a holding furnace inside the bridge construction and the holding furnace, the mold with a possibly subsequent secondary cooling section and the strand transport device can be swung out in the vertical direction from the casting position in the vertical direction by means of a hydraulic cylinder acting on the free end of the bridge construction in the casting direction in front of the axis .
Anhand der Zeichnung, die ein Ausführungsbeispiel darstellt, soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the drawing, which represents an exemplary embodiment.
Die Zeichnung zeigt eine Einrichtung zum horizontalen Stranggießen von Metallen in der Seitenansicht.The drawing shows a device for the horizontal continuous casting of metals in a side view.
Die Einrichtung besteht aus einem Warmhalteofen 1, an den seitlich eine horizontal liegende Kokille 2 angeschlossen ist und der eine Sekundärkühlstrecke 3 folgt. In Gießrichtung gesehen folgt weiter eine Strangtransportvorrichtung 4 mit zwei Treibrollenpaaren 5.The device consists of a holding furnace 1, to the side of which a
Der Warmhalteofen 1, die Kokille 2, die Sekundärkühlstrecke 3 und die Strangtransportvorrichtung 4 sind erfindungsgemäß auf einer gemeinsamen Brückenkonstruktion 6 angeordnet. Ein in dieser Einrichtung erzeugter Strang 7 kann in einer nachfolgenden Trennvorrichtung 8, die je nach Strangformat als Säge oder Schere ausgebildet ist, in Strangabschnitte unterteilt werden. Die Strangabschnitte werden von einem Rollgang 9 aufgenommen und weitertransportiert.The holding furnace 1, the
In weiterer Ausgestaltung der Erfindung ist die Brückenkonstruktion 6 um die unter dem Warmhalteofen 1 gelegte Achse 10 schwenkbar gelagert. Aus der in der Zeichnung dargestellten Gießposition ist die Einrichtung (1 bis 4) einschließlich der Brückenkonstruktion 6 durch Betätigung eines Hydraulikzylinders 11, der am freien Ende der Brückenkonstruktion 6 in Gießrichtung vor der Achse 10 im Anlenkpunkt 12 angreift, in vertikaler Richtung aus der Gießposition nach oben ausschwenkbar.In a further embodiment of the invention, the
Der Hydraulikzylinder 11 ist mit seinem Fußende 14 an einem Traggerüst 13 befestigt, auf dem während des Gießprozesses die Brückenkonstruktion 6 aufliegt. Das Traggerüst 13, die Trennvorrichtung 8 und der Rollgang 9 sind auf einer Platte 15 befestigt.The
Die Vorteile der erfindungsgemäßen Einrichtung liegen einerseits in der sehr kompakten Bauweise und andererseits darin, daß die reguläre Trennvorrichtung für den Strang auch als Nottrennvorrichtung benutzt werden kann, um ein sofortiges Trennen des Stranges und Schwenken der Gießeinrichtung zur Notentleerung über den Warmhalteofen zu bewerkstelligen, so daß eine Beschädigung der Kokillen vermieden wird. Dieser Vorteil macht sich insbesondere bei den sehr teuren Rohrkokillen bemerkbar.The advantages of the device according to the invention lie on the one hand in the very compact design and on the other hand in the fact that the regular separating device for the strand can also be used as an emergency separating device in order to bring about an immediate disconnection of the strand and pivot the pouring device for emergency emptying via the holding oven, so that damage to the molds is avoided. This advantage is particularly noticeable in the very expensive tubular molds.
