The mould arrangement and the furnace are connected via a compressible seal. During discontinuous, intermittent withdrawal of the strand, the weighing equipment is pref. operative for measurement while the withdrawal device is inoperative.

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 claim 1.

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 Multi-chamber furnace 1, which is a pressure chamber 3 through an inlet channel 2 with the to be poured molten metal, and a mold chamber 4, the the pressure chamber 3 is in flow connection.

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 pressure chamber 3 is assigned a pressure generating device 11, with which in Dependence on the degree of filling of the multi-chamber furnace 1 to maintain a constant metallostatic pressure in the mold chamber 4 the gas pressure of the melt-free volume regulated above the bath level in the pressure chamber 3 becomes.

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 multi-chamber furnace 1 is dynamically supported on a weighing device 6 with which the gross weight of the multi-chamber furnace 1 is recorded. Here is this Gross weight resulting from the empty weight of the ready-to-use multi-chamber furnace 1 and the weight of the molten metal located in the multi-chamber furnace 1 composed, a measure of the degree of filling of the multi-chamber furnace 1 and as such a controlled variable for the pressure generating device 11.

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 Multi-chamber furnace 1 via the weighing device 6 is independent of incrustations due to inevitable Slag formation in chambers 3 and 4. This will the measurement more reliable.

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 mold arrangement 5 is attached to the multi-chamber furnace 1. This Mold arrangement 5 can be made from a mold, for example for casting strips, or several juxtaposed molds, for example for multi-strand circular casting. Characteristic of The invention is that this mold arrangement 5 separately on an oven-independent Support frame 10 is mounted and a compressible seal 9 with the Multi-chamber furnace 1 is non-positively connected, with a flow connection between the mold arrangement 5 and the mold chamber 4 of the multi-chamber furnace 1 exists.

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 mold arrangement 5 and the multi-chamber furnace 1 horizontally directed force resulting from one by one Strand withdrawal device 8 caused strand withdrawal force reduced static Contact pressure from the positive connection of the mold arrangement 5 with the Multi-chamber furnace 1 results. Especially with the permanently oscillating strand draw an average, essentially constant contact pressure is established. The orthogonally acting vertical force of the multi-chamber furnace 1, which acts on the weighing device 6 remains from the process of Strand withdrawal unaffected.

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 weighing device 6 is to be activated as a measuring element only when the strand withdrawal device 8 is at rest. The discontinuous intermittent strand withdrawal is formed by successive cycles with the successive phases train-pause-recoil-pause, where the pauses can last for several seconds. During the breaks, the force between the mold arrangement 5 and the multi-chamber furnace 1 is free of dynamics and in this respect the break phases are particularly advantageously suitable for precisely determining the degree of filling of the multi-chamber furnace 1.
For the casting process, the slight vertical movement of the multi-chamber furnace 1 required for the weighing process is irrelevant given varying degrees of filling, because the molten metal enters through the seal 9 into the mold arrangement and only gradually solidifies there.
Advantageously, the gross weight detected by the weighing device 6 is relieved by the substantially constant weight portion of the mold arrangement 5 and the variable weight portion of the strand 7, and thus the ratio of the fill weight of the molten metal to the gross weight is improved in favor of a higher measuring accuracy.
In addition, by avoiding a rigid mechanical coupling between the multi-chamber furnace 1 and the mold arrangement 5, it is ensured that unavoidable, thermally induced distortions of the mold-side wall of the multi-chamber furnace 1 do not affect a change in position of the mold axes of a multi-strand casting system. Rather, such distortions are compensated for by the compressible seal 9, so that, independently of thermal deformation effects before the start of casting, mold axes of a multi-strand mold arrangement 5 which are aligned in parallel maintain their parallelism even during casting.
