Description

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 Metal, especially steel slabs, with copper plates for the broad sides of the Chill mold, which is supported on coolable support plates, with between the broad sides clampable narrow sides and with one connected to the support plates 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 there are electromagnetic ones Stirring or braking devices are used to move through a targeted bath the steel melt to achieve high steel quality. When using This is achieved by a targeted bath movement of the stirring devices Steel melt, which contains a high proportion of rectified crystallites with sufficient Exposure of inclusions achieved. Braking devices are targeted Lorentz forces exploited that a high outflow rate from the Reduce the pouring spout and thus 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. Various designs are used for the mold drives and suspensions Commitment. DE 40 23 672 A1 describes a liquid-cooled mold for this Continuous casting of metals known in which only the actual Crystallizer, including the copper plates with the associated support plates the adjustment device for the narrow sides by an oscillation device are moving. Spring elements are provided for the suspension of the support plates, which are attached to a supporting plate connected to a stationary base frame.

Die aus dieser Schritt bekannte Kokilleneinrichtung weist keine elektromagnetische Einrichtung auf.The mold device known from this step has no electromagnetic Establishment on.

Aus DE 31 12 039 C2 ist eine Stranggießkokille mit Rührspule für Rechteckstränge bekannt, bei der vier Stützplatten miteinander verspannt und im zusammengebauten Zustand von zwei durch Zugbolzen verspannten Längsträgern gehalten sind, in denen die Rühreinrichtungen vorgesehen sind.From DE 31 12 039 C2 is a continuous casting mold with a stirring coil for rectangular strands known, braced together in the four support plates and assembled Condition of two longitudinal beams braced by tie bolts, in which the stirring devices are provided.

Die konstruktive Verknüpfung von Stützplatten und Spule macht es erforderlich, daß in nachteiliger Weise die Rührspule, oder eine eventuell eingebaute Bremse, während des Betriebes von der Oszillationsvorrichtung mitbewegt wird.The constructive connection of support plates and coil makes it necessary that in disadvantageously the stirring coil, or a possibly built-in brake, during of the operation is moved by the oscillation device.

Gleiches gilt für die aus DE 31 06 591 A1 bekannte elektromagnetische Rühreinrichtung. Bei dieser für Stahlstranggießformen konzipierten Rührvorrichtung ist eine Rührwicklungskammer an einem oberen Teil des Kühlkastens angeordnet. In einer Ausgestaltung dieser Rührvorrichtung ist die Rührwicklung einstückig mit der Befestigungsplatte in den Kühlkasten frei ein- und ausbaubar. Hierbei dient die Befestigungsplatte als Deckel zum Verschließen der Öffnung der Rührwicklungskammer und bildet gleichzeitig deren Rückwand.The same applies to the electromagnetic known from DE 31 06 591 A1 Stirring device. In this stirring device designed for continuous steel casting molds an agitation winding chamber is arranged on an upper part of the cooling box. In In one embodiment of this stirring device, the stirring winding is integral with the Mounting plate can be freely installed and removed in the cooler. Here serves the Mounting plate as a lid to close the opening of the Stir winding chamber and forms the rear wall at the same time.

Bei diesem Aufbau der Rührkammer ist in aufwendiger Weise bei einem Wechsel der Kühlelemente stets die Rührspule mit zu demontieren.With this construction of the stirring chamber, the change is complicated Always remove the cooling elements from the cooling 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 aims to provide a mold according to the preamble of To create claim 1, which is a compact and low-torsion structure has, which is easily exchangeable and which without increasing by Oscillating device to be used a moving mass electromagnetic component.

Die Erfindung erreicht dieses Ziel durch die kennzeichnenden Merkmale des Anspruches 1. Die weiteren Ansprüche zeigen vorteilhatte Weiterbildung der Kokilleneinrichtung auf.The invention achieves this goal by the characterizing features of Claim 1. The other claims show advantageous further development of Chill mold on.

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. Through this Design is not only a high stiffness in the copper Broad sides of the mold supporting support plates reached, it is also next to the Targeted management of the cooling medium creates a freely usable space in which a electromagnetic stirring or braking device can be introduced.

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, it is close to the core cross-section of the strand approachable and thus able to achieve maximum magnetic penetration achieve. By attaching the stirrer to the support frame of the The mold moving mass is not increased during oscillation.

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 the mold device, the electromagnetic device perpendicular to To move the strand conveying direction. This opens up the possibility with extreme simple means the support plates for disassembly from the mold to release. In addition, the system can be any and without any further effort can be operated with or 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, the electromagnetic can be influenced without influencing the oscillating masses Facility to be moved parallel to the strand conveying direction even during the Operation to achieve an optimal setting of 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 support plates targeted guidance of the cooling medium and thus a defined heat dissipation to adjust.

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 is characterized by a special rigidity out. To further increase this rigidity, there are webs or ribs in the free space applicable.

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 on yokes supporting cantilevers the constructive advantage, particularly simple to be put together. This not only minimizes the installation time, it will also opens up the possibility of pre-assembling the mold using 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 detaching the electromagnetic device from the oscillating part of the mold device is also a light Height adjustment possible because there is free access from the outside. Furthermore only one spool or brake is required per strand, since this is also the case with one Replacement of the support plates remain in the system. In the known facilities are the 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 is done in simply by driving the coil core to the bottom of the trough is proceeded. The coil surrounding the coil core is also in the direction Move the support plate and stop just before the outer edge of the support plate. For the coil core is clamped securely.

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 on a common coil yoke, the The coil yoke is designed in a ring shape and is guided around the support plates.

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 protrusions at the top, each of which is located on Support the yokes. These support yokes are designed so that they are Narrow side adjustment include and in a simple manner without any hindrance can be removed from the system together with the support plate they carry are.

In vorteilhafter Weise besitzen die Tragjoche-Wasserführungen, um die Wasserzu-bzw. abfuhr mit den Stützplatten zu verbinden. Dabei sind zwischen den Stützplatten und den Tragjochen elastische Elemente vorgesehen, die eine horizontale Verstellung der Breitseiten zueinander ohne Behinderung der Wasserführung ermöglichen.Advantageously, the support yokes have water guides in order to supply or supply water. discharge to connect with the support plates.
