Die Erfindung betrifft eine Kokilleneinrichtung zum Erzeugen von Endlossträngen aus Metall, insbesondere von Brammen aus Stahl, mit Kupferplatten für die Breitseiten der Kokille, die sich an kühlbaren Stützplatten abstützen, mit zwischen den Breitseiten einklemmbaren Schmalseiten und mit einer mit den Stützplatten verbundenen Oszillationsvorrichtung.The invention relates to a mold device for producing endless strands of metal, in particular of steel slabs, with copper plates for the broad sides of the mold, which can be cooled Support the support plates with between the broad sides pinchable narrow sides and with one with the Support plates connected oscillation device.
In Stranggießkokillen zum Erzeugen von Stahlsträngen kommen elektromagnetische Rühr- oder Bremseinrichtungen zum Einsatz, um durch eine gezielte Badbewegung der Stahlschmelze eine hohe Stahlqualität zu erreichen. Beim Einsatz von Rühreinrichtungen wird dies erreicht durch eine gezielte Badbewegung der Stahlschmelze, die einen hohen Anteil gleichgerichteter Kristallite bei ausreichender Aufschwemmung der Einschlüsse erzielt. Bei Bremseinrichtungen werden gezielt Lorentzkräfte ausgenutzt, die eine hohe Auströmgeschwindigkeit aus dem Tauchausguß und damit die Höhe der Oberflächenwelle reduzieren.In continuous casting molds for the production of Steel strands come electromagnetic stirring or Brake devices used to pass through a targeted bath movement of the steel melt a high To achieve steel quality. When using stirring devices this is achieved through a targeted bath movement the molten steel, which accounts for a high proportion rectified crystallites with sufficient suspension of inclusions. For braking devices targeted use is made of Lorentz forces which a high outflow rate from the immersion nozzle and thus reduce the height of the surface wave.
Bei den Kokillenantrieben und Aufhängungen kommen verschiedene Bauformen zum Einsatz. So ist aus der DE 40 23 672 A1 eine flüssigkeitsgekühlte Kokille für das Stranggießen von Metallen bekannt, bei der ausschließlich der eigentliche Kristallisator, also die Kupferplatten mit den zugehörigen Stützplatten einschließlich der Verstelleinrichtung für die Schmalseiten, durch eine Oszillationseinrichtung zu bewegen sind. Für die Aufhfängung der Stützplatten sind Federelemente vorgesehen, die an einer mit einem ortsfesten Grundrahmen verbundenen Tragplatte befestigt sind.For mold drives and suspensions different designs are used. So is from DE 40 23 672 A1 a liquid-cooled Chill mold known for the continuous casting of metals which only the actual crystallizer, that is Including copper plates with the associated support plates the adjustment device for the narrow sides, are to be moved by an oscillation device. Spring elements are used to suspend the support plates provided that at one with a stationary Base frame connected support plate are attached.

Aus der WO 94/16844 ist eine Kokilleneinrichtung bekannt, bei der ebenfalls elektromagnetische Bauteile vorgesehen sind. Diese haben aber geteilte Kerne, so dass ein Teil der Keme beim Ausbau der Kokille mit dieser ausgebaut werden, da sie in die Wasserkästen integriert sind.WO 94/16844 is a mold device known in which also electromagnetic components are provided.

Bei diesem Aufbau der Rührkammer ist in aufwendiger Weise bei einem Wechsel der Kühlelemente stets die Rührspule mit zu demontieren.This structure of the stirring chamber is complex Way when changing the cooling elements always dismantle the stirring coil.
Die Erfindung verfolgt das Ziel, eine Kokilleneinrichtung
gemäß Oberbegriff des Patentanspruches 1
zu schaffen, die einen kompakten und verwindungsarmen
Aufbau aufweist, die leicht wechselbar ist und die
ohne Erhöhung der durch die Oszillationseinrichtung zu
bewegenden Masse einen Einsatz eines elektromagnetischen
Bauteils ermöglicht.The invention pursues the goal of a mold device
according to the preamble of
Die Erfindung erreicht dieses Ziel durch die
kennzeichnenden Merkmale des Anspruches 1. Die

characterizing features of
Erfindungsgemäß sind die Stützplatten trogförmig ausgebildet. Durch diese Ausgestaltung wird nicht nur eine hohe Steifigkeit in der aus Kupfer bestehenden Breitseiten der Kokille stützenden Stützplatten erreicht, es wird auch neben der gezielten Führung des Kühlmediums ein frei nutzbarer Raum geschaffen, in dem eine elektromagnetische Rühr- oder Bremsvorrichtung einbringbar ist.According to the support plates are trough-shaped educated. This configuration does not only high rigidity in the copper Broad sides of the mold supporting support plates reached, it is also used in addition to the targeted guidance of the cooling medium created a freely usable space in which a electromagnetic stirring or braking device can be introduced is.
Beim Einsatz einer Spule ist diese dabei nahe an den Kernquerschnitt des Stranges heranführbar und somit in der Lage, eine maximale magnetische Durchdringung zu erzielen. Durch die Anbringung der Rührvorrichtung an das Traggestell der Kokilleneinrichtung werden die bei der Oszillation bewegten Massen nicht vergrößert.When using a coil this is close can be brought up to the core cross section of the strand and thus able to achieve maximum magnetic penetration to achieve. By attaching the stirrer to the support frame of the mold the masses moved during the oscillation are not increased.
Darüber hinaus wird die Möglichkeit eröffnet, unabhängig von der oszillierenden Masse der Kokilleneinrichtung die elektromagnetische Vorrichtung senkrecht zur Strangförderrichtung zu bewegen. Hierdurch wird die Möglichkeit eröffnet, mit äußerst einfachen Mitteln die Stützplatten zur Demontage aus der Kokilleneinrichtung freizugeben. Außerdem kann die Anlage beliebig und ohne jeglichen weiteren Aufwand mit oder ohne Rühr- bzw. Bremseinrichtung betrieben werden.In addition, the possibility is opened regardless of the oscillating mass of the mold the electromagnetic device vertically to move to the strand conveying direction. hereby the possibility is opened with extremely simple means the support plates for disassembly from the mold release. In addition, the facility arbitrarily and without any further effort with or can be operated without a stirrer or braking device.
Weiterhin kann ohne Beeinflußung der oszillierenden Massen die elektromagnetische Einrichtung parallel zur Strangförderrichtung bewegt werden um sogar während des Betriebes eine optimale Einstellung der Rühr- bzw. Bremseinrichtung zu erreichen.Furthermore, it can affect the oscillating Crowds the electromagnetic device are moved parallel to the strand conveying direction an optimal setting even during operation to reach the stirring or braking device.
Durch die Einarbeitung von Kanälen in die trogförmig ausgestalteten Stützplatten läßt sich eine gezielte Führung des Kühlmediums und damit eine definierte Wärmeabfuhr einstellen.By incorporating channels into the trough-shaped designed support plates can be targeted guidance of the cooling medium and thus a defined one Adjust heat dissipation.
Der trogförmige Aufbau der Stützplatten zeichnet sich durch eine besondere Steifigkeit aus. Zur weiteren Erhöhung dieser Steifigkeit sind in den Freiraum Stege bzw. Rippen einbringbar.The trough-shaped structure of the support plates draws is characterized by a special rigidity. For further Increasing this stiffness are in the free space Bridges or ribs can be inserted.
Die Stützplatten besitzen in ihrer Ausgestaltung mit den sich auf Tragjochen abstützenden Auskragungen den konstruktiven Vorteil, besonders einfach zusammenfügbar zu sein. Hierdurch wird nicht nur die Einbauzeit minimiert, es wird auch die Möglichkeit eröffnet, mit einfachen Mitteln die Kokille vorzumontieren.The support plates have in their design with the overhangs supported on the yokes the constructive advantage, particularly simple to be put together. This will not only Installation time minimized, the possibility is also opened Pre-assemble the mold with simple means.
Durch das konstruktive Lösen der elektromagnetischen Einrichtung von dem oszillierenden Teil der Kokilleneinrichtung ist darüber hinaus eine leichte Höhenverstellbarkeit möglich, da der freie Zugang von außen besteht. Darüber hinaus ist nur eine Spule bzw. Bremse je Strang erforderlich, da diese auch bei einem Wechsel der Stützplatten in der Anlage verbleiben. Bei den bekannten Einrichtungen sind die demontierbaren Stützplatten jeweils mit einer elektromagnetischen Einrichtung in Reserve zu halten.By constructively loosening the electromagnetic Setup of the oscillating part of the In addition, mold installation is easy Height adjustment possible because of the free access from outside exists. In addition, only one coil or Brake required per line, as this is also the case with one Replacement of the support plates remain in the system. at the known devices are removable Support plates each with an electromagnetic device to keep in reserve.
Die Fixierung der elektromagnetischen Einrichtung als Rührspule geschieht in einfacher Weise dadurch, daß über einen Antrieb der Spulenkern bis zum Troggrund verfahren wird. Die den Spulenkern umgebende Spule wird dabei mit in Richtung Stützplatte verfahren und und kurz vor dem Außenrand der Stützplatte angehalten. Zur sicheren Positionierung wird der Spulenkern geklemmt.The fixation of the electromagnetic device as a stirring coil happens in a simple manner characterized in that up to a drive of the coil core is moved to the bottom of the trough. The coil core surrounding coil is also in the direction of the support plate procedure and and just before the outer edge of the Support plate stopped. For safe positioning the coil core is clamped.
Die einzelnen Spulenkerne stützen sich auf einen gemeinsamen Spulenjoch ab, das Spulenjoch ist dabei ringförmig ausgestaltet und um die Stützplatten herumgeführt.The individual coil cores are supported a common coil yoke, which is coil yoke designed in a ring and around the support plates led around.
Die einzelnen Stützplatten weisen kopfendig Auskragungen auf, die sich jeweils auf Tragjochen abstützen. Diese Tragjochen sind konstruktiv so ausgebildet, daß sie die Schmalseitenverstellung umfassen und in einfacher Weise ohne jegliche Behinderung zusammen mit der Stützplatte, die sie dabei tragen, aus der Anlage herausnehmbar sind.The individual support plates have a head end Cantilevers, each on supporting yokes support. These support yokes are designed so that that they include the narrow side adjustment and in a simple way without any hindrance together with the support plate they carry the system are removable.
