Description
Die Erfindung betrifft eine Horizontal-Stranggießanlage mit einem beheizbaren Mehrkammerofen, bestehend aus einer Druckkammer, die mit einer Kokillenkammer in Fließverbindung, steht und durch einen Einlaufkanal beschickbar ist, wobei zur Aufrechterhaltung eines konstanten metallostatischen Druckes in der Kokillenkammer die Druckverhältnisse in der Druckkammer in Abhängigkeit von ihrem Füllstand mit einer Druckerzeugungsvorrichtung geregelt werden, mit einer ofenabhängigen Kokillenanordnung, die mit der Kokillenkammer in Fließverbindung steht.The invention relates to a horizontal continuous caster with a heatable Multi-chamber furnace, consisting of a pressure chamber with a mold chamber in flow connection, and can be fed through an inlet channel, with the Maintaining a constant metallostatic pressure in the mold chamber the pressure conditions in the pressure chamber depending on their level a pressure generating device can be regulated with an oven-dependent Mold arrangement, which is in fluid communication with the mold chamber.
Eine aus der JP-A-60106647 bekannte gattungsgemäße Horizontal-Stranggießanlage betrifft die Wägung des Ofeninhaltes. Die Kokille ist nicht separat abgestützt, sondern mit dem Tundish fest verbunden.A horizontal continuous caster of the generic type known from JP-A-60106647 concerns the weighing of the oven contents. The mold is not supported separately, but with the tundish firmly connected.
Die GB-A-2156523 beschreibt eine "adjustabie connection" der Kokille zum Tundish in bezug auf die Strangabzugsachse. Zur Justierung wird eine Schraubenverbindung gelöst und danach wieder festgezogen.GB-A-2156523 describes an "adjustabie connection" of the mold to the tundish in with respect to the strand withdrawal axis. A screw connection is loosened for adjustment and then tightened again.
Bekannt ist aus DE 43 25 432 eine Waagerecht-Stranggieß-Anlage mit einem als
Druckkammer ausgebildeten Warmhaltegefäß, das durch einen Einlaufkanal mit der
zu vergießenden Metallschmelze beschickt wird und aus dem die Metallschmelze über
einen Abgußkanal entnommen und einer Kokille zugeführt wird. Das Warmhaltegefäß
ist druckdicht mit einem Deckel verschlossen, an den eine Druckerzeugungseinrichtung
angeschlossen ist.
Zur Aufrechterhaltung eines konstanten metallostatischen Druckes in der Kokille wird
der Pegel der Metallschmelze im Abgußkanal konstantgehalten, indem die
Druckverhältnisse im Warmhaltegefäß entsprechend seinem Füllungsgrad variiert
werden. Dazu sind im Abgußkanal und im Warmhaltegefäß Badspiegel-Erfassungseinrichtungen
vorgesehen, die in direkter Weise auf die mediale
Grenzschicht zwischen dem von der Metallschmelze gefüllten und ungefüllten
Volumen des Abgußkanals bzw. des Warmhaltegefäßes Bezug nehmen.
Aus der Erfahrung beim Betrieb derartiger Einrichtungen ist jedoch bekannt, daß
mechanische, thermische oder elektrische Badspiegel-Erfassungseinrichtungen in
derartiger Anordnung einerseits wegen der hohen Temperaturen und andererseits,
insbesondere beim Vergießen von Schwermetallegierungen, wegen des auftretenden
Schlackeanfalls sehr unzuverlässig sind.DE 43 25 432 discloses a horizontal continuous casting installation with a holding vessel designed as a pressure chamber, which is charged with the molten metal to be cast through an inlet channel and from which the molten metal is removed via a pouring channel and fed to a mold. The warming vessel is closed pressure-tight with a lid to which a pressure generating device is connected.
In order to maintain a constant metallostatic pressure in the mold, the level of the molten metal in the pouring channel is kept constant by varying the pressure conditions in the holding vessel according to its degree of filling. For this purpose, bath level detection devices are provided in the pouring channel and in the holding vessel, which refer directly to the medial boundary layer between the volume of the pouring channel or the holding vessel filled and unfilled by the molten metal.
From experience in the operation of such devices, however, it is known that mechanical, thermal or electrical bath level detection devices in such an arrangement are very unreliable on the one hand because of the high temperatures and on the other hand, in particular when casting heavy metal alloys, because of the slag accumulation that occurs.
Ein weiteres Problem bei der bekannten Stranggießanlage besteht darin, daß beim mehrsträngigen Stranggießen infolge unvermeidlicher thermischer Verformung des Ofengefäßes die Längsachsen der außenliegenden Kokillen in Gießrichtung einen in seiner Größe variablen, spreizenden Winkel zur untereinander parallelen Strangführung der Strangachsen einnehmen. Beim Abziehen der parallel geführten Stränge treten in den einzelnen Strängen unterschiedliche Strangabzugskräfte auf, die durch Querkräfte in Abhängigkeit der Winkellage der jeweiligen Kokille zur Strangabzugsrichtung hervorgerufen werden. Darüber hinaus wird die Strangqualität durch Gefügeveränderungen während des Erstarrungsprozesses negativ beeinflußt.Another problem with the known continuous caster is that multi-strand continuous casting due to inevitable thermal deformation of the The longitudinal axes of the outer molds in the casting direction in one its size variable, spreading angle to the parallel to each other Take strand guidance of the strand axes. When pulling out the parallel Strands have different strand pull-off forces in the individual strands, by transverse forces depending on the angular position of the respective mold Strand withdrawal direction are caused. In addition, the strand quality negatively influenced by structural changes during the solidification process.
Der Erfindung liegt die Aufgabe zugrunde, eine Horizontal-Stranggießanlage der eingangs erwähnten Art anzugeben, bei der die Zuverlässigkeit der Füllstandsmessung verbessert wird.The invention has for its object a horizontal continuous casting machine Specify the type mentioned, in which the reliability of the Level measurement is improved.
Erfindungsgemäß wird diese Aufgabe mit den Mitteln des Patentanspruchs 1 gelöst.According to the invention, this object is achieved with the means of
Die Erfindung wird nachstehend am Beispiel einer Horizontal-Stranggießanlage näher erläutert. Dazu ist in Figur 1 eine schematisierte, teilweise geschnittene Darstellung einer Horizontal-Stranggießanlage gezeigt.The invention is illustrated below using the example of a horizontal continuous caster explained. For this purpose, a schematic, partially sectioned illustration is shown in FIG a horizontal continuous caster shown.
Bestandteil dieser Horizontal-Stranggießanlage ist ein druckgesteuerter
Mehrkammerofen 1, der eine Druckkammer 3, die durch einen Einlaufkanal 2 mit der
zu vergießenden Metallschmelze beschickt wird, und eine Kokillenkammer 4, die mit
der Druckkammer 3 in Fließverbindung steht, aufweist. A component of this horizontal continuous caster is a pressure-controlled one
Der Druckkammer 3 ist eine Druckerzeugungsvorrichtung 11 zugeordnet, mit der in
Abhängigkeit vom Füllungsgrad des Mehrkammerofens 1 zur Aufrechterhaltung eines
konstanten metallostatischen Druckes in der Kokillenkammer 4 der Gasdruck des
schmelzefreien Volumens oberhalb des Badspiegels in der Druckkammer 3 geregelt
wird.The
Der Mehrkammerofen 1 ist auf einer Wägeeinrichtung 6 dynamisch gelagert, mit der
das Bruttogewicht des Mehrkammerofens 1 erfaßt wird. Dabei ist dieses
Bruttogewicht, das sich aus dem Leergewicht des betriebsbereiten Mehrkammerofens
1 und dem Gewicht der im Mehrkammerofen 1 befindlichen Metallschmelze
zusammensetzt, ein Maß für den Füllungsgrad des Mehrkammerofens 1 und als
solches Regelgröße für die Druckerzeugungsvorrichtung 11.The
Die erfindungsgemäße Art der Meßgrößengewinnung für den Füllungsgrad des
Mehrkammerofens 1 über die Wägeeinrichtung 6 ist unabhängig von Verkrustungen durch unvermeidliche
Schlackenbildung in den Kammern 3 und 4. Dadurch wird
die Messung zuverlässiger.The type of measurement quantity according to the invention for the degree of filling of the
An dem Mehrkammerofen 1 ist eine Kokillenanordnung 5 angebaut. Diese
Kokillenanordnung 5 kann aus einer Kokille, beispielsweise zum Gießen von Bändern,
oder mehreren nebeneinandergeordneten Kokillen, beispielsweise zum
mehrsträngigen Rundstrangguß, aufgebaut sein. Merkmal der
Erfindung ist es, daß diese Kokillenanordnung 5 separat auf einen ofenunabhängigen
Tragrahmen 10 montiert ist und über eine kompressible Dichtung 9 mit dem
Mehrkammerofen 1 kraftschlüssig verbunden ist, wobei eine Fließverbindung
zwischen der Kokillenanordnung 5 und der Kokillenkammer 4 des Mehrkammerofens
1 besteht.A
Dabei wirkt zwischen der Kokillenanordnung 5 und dem Mehrkammerofen 1 eine
horizontal gerichtete Kraft, die sich aus einer um die von einer
Strangabzugseinrichtung 8 hervorgerufene Strangabzugskraft verminderte statische
Anpreßkraft aus der kraftschlüssigen Verbindung der Kokillenanordnung 5 mit dem
Mehrkammerofen 1 ergibt. Insbesondere beim permanent oszillierenden Strangabzug
stellt sich dabei eine mittlere, im wesentlichen konstante Anpreßkraft ein. Die
orthogonal dazu wirkende, vertikal gerichtete Gewichtskraft des Mehrkammerofens 1,
die auf die Wägeeinrichtung 6 wirkt, bleibt dabei von dem Vorgang des
Strangabzuges unbeeinflußt.One acts between the
In besonderer Ausgestaltung der Erfindung ist bei diskontinuierlich intermittierendem
Strangabzug vorgesehen, die Wägeeinrichtung 6 als Meßglied ausschließlich bei
ruhender Strangabzugseinrichtung 8 zu aktivieren. Der diskontinuierliche
intermittierende Strangabzug wird durch aufeinanderfolgende Zyklen mit den
aufeinanderfolgenden Phasen Zug-Pause-Rückstoß-Pause gebildet, wobei die
Pausen eine Dauer von mehreren Sekunden haben können. Während der Pausen ist
die Kraft zwischen der Kokillenanordnung 5 und dem Mehrkammerofen 1 dynamikfrei
und insoweit sind die Pausenphasen besonders vorteilhaft zur präzisen Bestimmung
des Füllungsgrades des Mehrkammerofens 1 geeignet.
Für den Gießprozeß ist die für den Wägeprozeß erforderliche geringe vertikale
Bewegung des Mehrkammerofens 1 bei wechselnden Füllungsgraden unerheblich,
weil die Metallschmelze im fließfähigen Zustand durch die Dichtung 9 bis in die
Kokillenanordnung eintritt und erst dort allmählich erstarrt.
Vorteilhafterweise wird dadurch das mit der Wägeeinrichtung 6 erfaßte Bruttogewicht
um den im wesentlichen konstanten Gewichtsanteil der Kokillenanordnung 5 und den
variablen Gewichtsanteil des Stranges 7 entlastet und somit das Verhältnis des
Füllgewichtes der Metallschmelze zum Bruttogewicht zugunsten einer höheren
Meßgenauigkeit verbessert.
Darüber hinaus ist durch Vermeidung einer starren mechanischen Kopplung zwischen
dem Mehrkammerofen 1 und der Kokillenanordnung 5 gewährleistet, daß
unvermeidbare, thermisch bedingte Verwerfungen der kokillenseitigen Wandung des
Mehrkammerofens 1 nicht auf eine Lageveränderung der Kokillenachsen einer
mehrsträngigen Gießanlage durchgreifen. Vielmehr werden derartige Verwerfungen
durch die kompressible Dichtung 9 kompensiert, so daß unabhängig von thermischen
Formänderungseffekten vor dem Gießbeginn parallel ausgerichtete Kokillenachsen
einer mehrsträngigen Kokillenanordnung 5 auch während des Gießens ihre
Parallelität beibehalten.In a special embodiment of the invention, in the case of discontinuously intermittent strand withdrawal, the
For the casting process, the slight vertical movement of the
