Preferred Features: The support arm moves the narrow side parts vertically about a pivoting axis or along a curve.

Description

Die Erfindung betrifft eine Bandgiessmaschine gemäß den Merkmalen des Oberbegriffes von Anspruch 1.The invention relates to a strip casting machine according to the features of the preamble of claim 1.

Es ist bekannt, mit Zweirollenbandgiessmaschinen kontinuierlich Bänder aus flüssiger Metallschmelze, insbesondere aus Stahlschmelze herzustellen. Das flüssige Metall wird dabei kontinuierlich einem, durch zwei angetriebene Giessrollen definierten, Giessspalt zugeführt. Vor und im Giessspalt erstarrt flüssiges Metall und ein mindestens teilweise erstarrtes Band wird durch die Giessrollen ausgefördert. Dieses Band kann weiteren kontinuierlichen oder diskontinuierlichen Operationen wie Kühlen, Wiedererwärmen, Warm- oder Kaltwalzen, Profilumwandlung, Oberflächenvergütung, Besäumung etc. unterzogen werden.It is known with two-roll belt casting machines continuous strips of liquid To produce molten metal, in particular from molten steel. The liquid Metal is continuously fed into one, defined by two driven casting rolls, Casting gap fed. Liquid metal solidifies in front of and in the casting gap an at least partially solidified belt is conveyed out through the casting rolls. This tape can perform further continuous or discontinuous operations such as cooling, reheating, hot or cold rolling, profile conversion, surface treatment, Trimming etc.

Es ist weiter bekannt, bei Bandgiessmaschinen mit zwei im wesentlichen parallel angeordneten Giessrollen, den Giessspalt mit Schmalseiten zu begrenzen. Die Schmalseitenteile werden dabei durch eine Anstelleinrichtung federnd an die Stirnseiten von Ballen der beiden Giessrollen angestellt. Die Giessrollen und in der Regel auch die beiden Anstelleinrichtungen für die Schmalseiten sind auf einem Maschinenständer abgestützt. Beim Giessen von Bändern, insbesondere von Stahlbändem, werden die Schmalseiten sowohl durch die Reibung an den Giessrollen als auch im unteren Teil durch die Reibung des erstarrten Bandes durch abrasiven Verschleiss abgenützt und müssen in einer Giesspause ersetzt werden. Beim Auswechseln werden die Schmalseiten aus der Giessposition, in welcher die Schmalseiten an den Ballen anliegen, im wesentlichen waagerecht mittels der Anstelleinrichtung von den Ballen weg in eine Anstellposition bewegt und anschliessend mittels Schmalseitenwechselvorrichtung z. B. Robotem, die auf jeder Maschinenseite auf der Giessbühne angeordnet sind, nach oben aus der Anstellposition entfernt (vgl. japanische Offenlegungsschrift JP-5-32 95 83 A). Anschliessend werden die Schmalseiten auf einem Wagen abgelegt und in die Schmalseiten-Überholungswerkstatt gebracht. Eine überholte Schmalseite wird vorgeheizt, mit dem Roboter abgehoben und von oben in die Anstellposition gebracht und an der Maschine befestigt. Werden solche Roboter auf beiden Maschinenseiten in der Nähe des Maschinenständers angeordnet, so versperren sie die Zugänglichkeit zur Bandgiessmaschine. Werden die Roboter auf 2 - 3 m Entfernung vom Maschinenständer angeordnet, so werden die Roboter entsprechend gross und sperrig und verlieren an Präzision zum Einsetzen der Schmalseitenteile in die Anstellposition. Im weiteren müssen vor dem Absetzen der Schmalseitenteile auf dem Maschinenständer alle Versorgungsleitungen wie beispielsweise Heizung, Kühlung, elektrische Leitungen, Druckmedien etc. angeschlossen werden. Die Montage und Demontage von Schmalseiten mittels Roboterarmen etc. erfordert eine unbehinderte Zugänglichkeit des Roboterarmes zu den Schmalseiten in der Anstellposition. Diese freie Zugänglichkeit erschwert eine Umhüllung der Giessmaschine und den Aufbau einer Inertgasatmosphäre zum Schutz des Stahlbandes und des gegossenen Bandes gegen Oxydation.It is also known in the case of strip casting machines with two essentially parallel arranged casting rollers to limit the casting gap with narrow sides. The Narrow side parts are resilient to the by an adjusting device Face of bales of the two casters. The casting rolls and in the As a rule, the two adjusting devices for the narrow sides are on one Machine stand supported. When casting tapes, especially of Steel straps, the narrow sides are affected both by the friction on the Casting rollers as well as in the lower part due to the friction of the solidified belt worn through abrasive wear and must be replaced in a casting break become. When changing the narrow sides from the casting position, in which the narrow sides lie against the bales, essentially horizontally by means of the adjusting device moved away from the bale into an adjusting position and then by means of narrow side changing device z. B. robots on each machine side are arranged on the casting platform, upwards from the Position removed (see Japanese Patent Application Laid-Open No. 5-32 95 83 A). Subsequently the narrow sides are placed on a trolley and into the Narrow side overhaul brought. An outdated narrow side will preheated, lifted off with the robot and brought from above into the working position and attached to the machine. Such robots become on both machine sides arranged near the machine stand, so they block the Accessibility to the strip casting machine. If the robots are at a distance of 2 - 3 m arranged by the machine stand, so the robots are accordingly large and bulky and lose precision when inserting the narrow side parts in the starting position. Furthermore, before the narrow side parts are removed on the machine stand all supply lines such as Heating, cooling, electrical lines, pressure media etc. can be connected. The assembly and disassembly of narrow sides using robot arms etc. requires unobstructed accessibility of the robot arm to the narrow sides in the starting position. This free access makes it difficult to wrap the Casting machine and the creation of an inert gas atmosphere to protect the steel strip and the cast tape against oxidation.

Bandgiessmaschinen mit 2 Giessrollen wurden mit Giessrollendurchmesser von 500 - 1500 mm gebaut. Bei Bandgiessmaschinen mit einem Giessrollendurchmesser über 800 mm werden auch die Schmalseitenteile mit ihren Dichtflächen, die in Gleitkontakt mit den Stirnseiten der Giessrollen stehen, entsprechend grösser. Auch müssen die Anstelleinrichtungen, die die Schmalseitenteile oder die Schmalseitenplatte dichtend an die Giessrollen andrücken, für höhere Ansprüche ausgelegt werden. Alle diese Erfordernisse, die ein Giessrollendurchmesser über 800 mm verursacht, erschweren einen präzisen raschen Wechsel der Schmalseitenteile. Belt casting machines with 2 casting rolls were with a casting roll diameter of 500 - 1500 mm built. For strip casting machines with a casting roll diameter The narrow side parts with their sealing surfaces, which are in sliding contact with the end faces of the casting rolls, correspondingly larger. Also, the adjusting devices, the narrow side parts or the Press the narrow side plate onto the casting rollers to seal it, for higher demands be interpreted. All of these requirements over a cast roll diameter 800 mm, make it difficult to change the narrow side parts quickly and precisely.

Der Erfindung liegt die Aufgabe zugrunde, eine Bandgiessmaschine zu schaffen, die die im Stand der Technik genannten Nachteile überwindet und die insbesondere das Auswechseln der Schmalseiten verbessert und dadurch die Rüstzeit zwischen zwei Güssen verkürzt. Die Schmalseiten sollen dabei genauer positionierbar und bis zum Giessbeginn beheizbar sein. Im weiteren sollen die Schmalseiten während der Wechselbewegung mit allen Versorgungs- und Detektorleitungen des Überwachungssystems für solche Schmalseiten verbunden bleiben. Ein wesentliches Teilziel ist eine verbesserte Zugänglichkeit zu den Giessrollen, insbesondere für einen Giessrollenwechsel und ein einfacherer Schutz gegen Sauerstoffzutritt zum Eingiess- und Bandaustrittseitigem Teil der Giessmaschine (Inertisierung). Auch sollen die Probleme, die mit einem Rollendurchmesser grösser als 800 mm und entsprechend grossen Schmalseitenplatten entstehen, gelöst werden.The invention has for its object to provide a strip casting machine, which overcomes the disadvantages mentioned in the prior art and which in particular the exchange of the narrow sides improved and thereby the makeready between shortened two fonts. The narrow sides should be positioned more precisely and be heatable until the start of watering. In the further the narrow sides during the alternating movement with all supply and detector lines of the Monitoring system for such narrow sides remain connected. An essential one Part of the goal is improved accessibility to the casting rolls, in particular for a cast roll change and easier protection against the ingress of oxygen to the part of the casting machine on the entry and exit side (inerting). Also, the problems with a roll diameter larger than 800 mm are said to be and correspondingly large narrow side plates are created, solved.

Gemäß der Erfindung wird diese Aufgabe durch die Summe der Merkmale von Anspruch 1 gelöst.According to the invention, this object is achieved by the sum of the features of Claim 1 solved.

Die Bewegung der Schmalseitenplatte mittels dem Trägerelement kann geradlinig vertikal oder schräg sowie gebogen nach unten erfolgen. Das Trägerelement ist vorteilhaft als Tragarm ausgebildet. Der Tragarm kann dabei um eine Achse verschwenken oder entlang einer Kurve sich bewegen. Unterhalb der Maschine kann die Schmalseite am Tragarm gegen eine neue Schmalseite ausgewechselt und auf dem gleichen Weg wieder in die Anstellposition verschoben werden. Es ist zu beachten, dass die Bezeichnung Anstellposition jede Plattenstellung zwischen der Giessposition und einer Auswechselposition beinhaltet. Gemäß einem Ausführungsbeispiel kann in einem ersten Bewegungsschritt der Tragarm die Schmalseite im wesentlichen horizontal und in Längsachse der Giessrollen vom Maschinenständer weg verschieben. Die Verschiebung der Schmalseite kann auf einer horizontalen Verschiebebahn, die etwa auf einer Höhe unterhalb der Giessrollen liegt, erfolgen. In einem zweiten Bewegungsschritt kann dann der Tragarm mit der Schmalseite im wesentlichen parallel zu den Stirnseiten der Giessrollen nach unten verstellt werden.The movement of the narrow side plate by means of the carrier element can be straight vertically or at an angle as well as bent downwards. The carrier element is advantageously designed as a support arm. The support arm can pivot about an axis or move along a curve. Can below the machine exchanged the narrow side on the support arm for a new narrow side and be moved back to the starting position in the same way. It's closed note that the designation position every plate position between the Casting position and an exchange position includes. According to one embodiment in a first step the arm can move the narrow side essentially horizontal and in the longitudinal axis of the casting rolls from the machine stand move away. The shift of the narrow side can be on a horizontal sliding track, which is approximately at a level below the casting rolls lies. In a second movement step, the support arm with the Narrow side essentially parallel to the end faces of the casting rolls downwards be adjusted.

Die Verschiebebahn kann die Schmalseite einer Schmalseitenwechselstation zuführen, die räumlich von der Giessbühne durch eine Wand getrennt ist. Eine solche Abtrennung der Schmalseitenwechselstation erlaubt eine geordnete und saubere Durchführung folgender Arbeiten, wie Reinigung, Wartung, Wechsel, Einstellung, Vorheizung der Schmalseite etc. unter Ausschluss einer Unfallgefahr.The sliding track can feed the narrow side to a narrow side change station, which is spatially separated from the casting platform by a wall. Such Separation of the narrow side change station allows an orderly and clean Carrying out the following work, such as cleaning, maintenance, changing, setting, Preheating the narrow side etc. to the exclusion of an accident risk.

Um die Bandgiessmaschine im Verhältnis zur Bandbreite schmal bauen zu können, kann gemäß einem weiteren Ausführungsbeispiel, das Schmalseitenteil zwischen den Lagerzapfen bzw. Lagerstellen der Giessrollen nach unten verschiebbar sein. Die Schmalseite kann mit oder ohne Anstelleinrichtung zwischen den Stirnseiten der Rollenballen und dem Maschinenständer nach unten verschiebbar sein. Gegebenenfalls werden hierzu die Giessrollen auf Abstand aufgefahren.In order to be able to build the strip casting machine narrow in relation to the strip width, can according to a further embodiment, the narrow side part between the journal or bearing points of the casters can be moved downwards his. The narrow side can with or without adjusting device between the End faces of the roller bales and the machine stand can be moved downwards his. If necessary, the casting rolls are moved up at a distance.

Die Giessmaschine kann besonders schmal gebaut werden, wenn die Anstell- und Positioniereinrichtung auf dem Maschinenständer angeordnet ist und mit dem Schmalseitenteil in Anstellposition an- und abkuppelbar ist.The casting machine can be made particularly narrow if the leaning and Positioning device is arranged on the machine stand and with the Narrow side part can be coupled and uncoupled in the position.

Unabhängig davon, ob die Anstell- und Positioniereinrichtung zusammen mit dem Schmalseitenteil absenkbar ist oder ob die Anstelleinrichtung beim Auswechseln der Schmalseite auf dem Maschinenständer verbleibt, kann die Bewegung zwischen der Anstell- und Giessposition mittels einem Druckmedium und Kolbenzylindereinheiten oder elektromechanisch erfolgen.Regardless of whether the adjusting and positioning device together with the Narrow side part is lowerable or whether the adjusting device when changing the narrow side remains on the machine stand, the movement between the starting and casting position by means of a pressure medium and piston cylinder units or done electromechanically.

Wenn das Schmalseitenteil in die Anstell- oder Giessposition gebracht ist, kann, wenn erwünscht, der Tragarm vom Schmalseitenteil getrennt werden. Gemäß einem vorteilhaften Ausführungsbeispiel kann der Tragarm auch in Giessposition mit dem Schmalseitenteil verbunden bleiben. When the narrow side part is brought into the starting or pouring position, if desired, the support arm can be separated from the narrow side part. According to one advantageous embodiment, the support arm can also in the casting position stay connected to the narrow side part.

Verschiebt sich das Schmalseitenteil zusammen mit der Anstelleinrichtung nach unten, d. h. die Anstelleinrichtung ist ebenfalls mobil, so benötigt sie in der Anstellposition gegenüber dem Maschinenständer eine Zentrierung und Stützflächen zur Einleitung der Anstellkraft in den Maschinenständer.Moves the narrow side part together with the adjusting device below, d. H. the adjusting device is also mobile, so it needs in the setting position a centering and support surfaces compared to the machine stand to initiate the positioning force in the machine stand.

Die Schmalseitenwechseleinrichtung besteht vorteilhafterweise aus einem Tragarm mit einem Vertikal- und einem Horizontalträger, wobei der Horizontalträger in der Regel mit einer Hubeinrichtung verbunden ist.The narrow side changing device advantageously consists of a Support arm with a vertical and a horizontal beam, the horizontal beam is usually connected to a lifting device.

Damit die verschiedenen Versorgungsmedien (Heizung, ev. Kühlung, elektrischer Strom, Druckmedien etc.) für die Schmalseitenteile auch während der Verschiebung angeschlossen bleiben können, wird vorgeschlagen, die horizontale Verschiebebahn mit einer Medienschleppkette für die Leitungen der Versorgungsmedien der Schmalseitenteile zu versehen.So that the various supply media (heating, possibly cooling, electrical Electricity, print media etc.) for the narrow side parts also during the shift can remain connected, it is proposed the horizontal sliding track with a media drag chain for the lines of the supply media of the narrow side parts.

Um die Abdichtung zwischen den sich drehenden Giessrollen und den stationären Schmalseitenteilen zu verbessern, können die Schmalseiten mit elektromagnetischen Spulen zur Erzeugung eines elektromagnetischen Feldes für eine Spaltabdichtung versehen werden.The seal between the rotating casters and the stationary ones To improve narrow side parts, the narrow sides can be electromagnetic Coils for generating an electromagnetic field for a gap seal be provided.

Eine zusätzliche Verkürzung der Wechselzeit für die Schmalseitenteile kann erreicht werden, wenn auf beiden Seiten der Giessrollen zwei Schmalseitenwechselvorrichtungen angeordnet sind, wobei die abgenutzte Schmalseite von der einen Wechselvorrichtung wegführbar und die neue Schmalseite von der anderen Wechselvorrichtung zuführbar ist.An additional reduction in the changeover time for the narrow side parts can be achieved if there are two narrow side changing devices on both sides of the casting rolls are arranged, the worn narrow side of one Exchangeable device and the new narrow side from the other Changing device can be fed.
