Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Mehrfach-Horizontalstranggießanlage und eine Mehrfach-Horizontalstranggießanlage.The invention relates to a method for operating a multiple horizontal continuous caster and a multiple horizontal caster.
Mehrfach-Horizontalstranggießanlagen sind bekannt, z.B. aus der EP 0 239 919 A2 oder der DE 26 58 242 A1. Derartige Anlagen bestehen im wesentlichen aus einem Verteilergefäß mit mehreren einzelnen Kokillen, wobei die Kokillen entweder direkt oder über eine Zwischenplatte an dem Verteilergefäß befestigt sind und einer der Anzahl der erzeugten Stränge entsprechenden Anzahl von Strangtransport- bzw. Auszieheinrichtungen und Strangtrenneinrichtungen.Multiple horizontal caster is known e.g. from the EP 0 239 919 A2 or DE 26 58 242 A1. Such systems exist in essentially from a distribution vessel with several individual molds, the molds either directly or via an intermediate plate on the Distribution vessel are attached and one of the number of strands generated corresponding number of strand transport or extraction devices and Strand cutting devices.
Die Strangauszieheinrichtungen bestehen entweder aus angetriebenen Rollen oder einem hydraulisch anstellbaren Klemmbackensystem, das in Strangachsrichtung bewegbar ist (DE-U1 85 22 740.1).The strand pullers consist of either driven ones Rollers or a hydraulically adjustable jaw system that in Strand axis direction is movable (DE-U1 85 22 740.1).
Im Falle von Störungen während des Gießbetriebes an einzelnen Strangadern sind zur Unterbrechung der Schmelzenzufuhr vom Verteiler zur Kokille zwischen beiden Schieberverschlüsse angeordnet. In the event of malfunctions during the casting operation on individual Strand cores are used to interrupt the melt supply from the distributor to Mold arranged between the two slide closures.
Derartige Anlagen sind maschinentechnisch aufwendig und vor allem aufgrund des großen Abstandes zwischen den einzelnen Kokillen gießtechnisch nachteilig. Auch erfordern sie einen erheblichen Platzbedarf.Such systems are mechanically complex and above all due to the large distance between the individual molds disadvantageous in terms of casting technology. They also require a significant amount Space requirements.
Die Erfindung befaßt sich daher mit dem Problem, vor allem beim Vergießen größerer Schmelzenmengen zu Strängen geringerer Querschnittsfläche auf engstem Raum eine möglichst große Anzahl von Gießadern unterzubringen und Störfälle zu beheben, sowie die Temperaturführung der Schmelze im Verteiler zu verbessern und den gerätetechnischen Aufwand zu reduzieren.The invention is therefore concerned with the problem, especially when Pour larger quantities of melt into strands of smaller ones Cross-sectional area in the smallest space as large as possible of To accommodate casting lines and to remedy faults, as well as the temperature control of the melt in the Improve distributors and reduce the technical outlay on equipment.

Gemäß Fig. 1 besteht die Mehrfach-Horizontalstranggießanlage aus einem
Verteiler 10 mit Deckel 12 und Verteilerwagen 13 sowie an dem Verteiler
10 angebrachten Kokillenblock 40, woran sich mit Abstand eine
Strangauszieheinrichtung 50, eine Strangtrenneinrichtung 70 und ggf.
eine Verformungsvorrichtung 20 für den Strang 30 anschließen.1, the multiple horizontal caster consists of one
In den Fig. 4 und 5 ist ein Kokillenblock 40 dargestellt, der eine
kompakte Bauweise und geringe Strangabstände gewährleistet. Der
Kokillenblock 40 besteht aus einem Gehäuse 41 mit mehreren Ausnehmungen
zur Aufnahme der aus Kokillengehäuse 45 mit darin befindlichem
Kupferteil 42 und Grafitteil 43 bestehenden Kokille. Die Kokille ist
wassergekühlt. Die Wasserzufuhr erfolgt je Kokille über einen der
Anschlußstutzen 44 des Gehäuses 41. Die Wasserführung wird von den
Anschlußstutzen 44 fortgesetzt in den Kanälen 46 des Gehäuses 41 und das
Wasser gelangt über Durchbrechungen 47, z.B. Bohrungen in den vom
Kokillengehäuse 45 und den Kupfer- bzw. Grafitteil 42, 43 gebildeten
Spalt und wird entsprechend am Kokillenende über Durchbrechungen 47'
und Kanäle 46' abgeführt. Die Ausnehmungen zur Aufnahme der Kokillen in
den Kokillenblock sind so dimensioniert, daß die Kokillen mit dem
größten Kokillenformat aufgenommen werden können. Bei kleinformatigen
Kokillen wird ein Durchmesserausgleich, z. B. durch entsprechende
Verdicktung des Kokillengehäuses 45 vorgenommen, um eine gewünschte
Spaltgröße zwischen Kokillengehäuse 45 und Kupferteil 42 bzw. Grafitteil
43 einzustellen. Die Kokille wird im Gehäuse 41 durch einen Flanschring
48 am Kokillenaustrittsende gehalten.4 and 5, a
Der Kokillenblock 40 ist durch geeignete Mittel, wie z. B.
Spannzylinder, in an sich bekannter Weise am Verteiler 10 befestigt. Die
Art des Überganges vom Verteiler 10 zum Kokillenblock 40 ist in Fig. 6
näher dargestellt. Der Verteiler 10 weist in der Seitenwand 11 eine den
zu erzeugenden Strängen entsprechende Anzahl von Ausgußöffnungen 14 auf. The
Die Achsen 49 der Ausnehmungen im Gehäuse 41 fallen im eingebauten
Zustand mit den Achsen der Kokillen 42, 43, 45 zusammen und bevorzugt
fluchten sie mit den Achsen 15 der Ausgußöffnungen 14 des Verteilers 10,
wenn auch ein geringer Versatz nicht schädlich ist. An der dem Verteiler
10 zugeordneten Stirnseite des Gehäuses 41 des Kokillenblocks 40 ist ein
Kanalstein 16 angeordnet, der von einem Ring 17 mit nach innen gezogenem
Flansch gehalten und gegen einen Bornitridring 18 auf der Einlaufseite
des Kokillenteils 42 gepreßt wird. Gegen den Verteiler 10 ist das
Gehäuse 41 mittels ff-Masse 19 abgedichtet.The
Die Fig. 2 und 3 zeigen eine Strangauszieheinrichtung für die Stränge
30. In der Ziehrichtung der Stränge 30 sind zwei Ziehaggregate, die die
Strangauszieheinrichtungen 50 bilden, hintereinander geschaltet, die
zeitlich wechselnd mit den Strängen 30 kraftschlüssig verbindbar sind.
Der Strangabzug erfolgt schrittweise jeweils mit einem der
Ziehaggregate, das mit den Strängen kraftschlüssig verbunden ist,
während das andere Ziehaggregat in die Ausgangsstellung zurückbewegt
wird. Diese Hin- und Herbewegung der Ziehaggregate der
Strangauszieheinrichtung 50 erfolgt durch Betätigung von Ziehzylindern
54, die auf einem Grundrahmen 51 befestigt sind. Die Kolbenstangen der
Ziehzylinder 54 greifen an einen Mitnehmer 55 an, der Bestandteil eines
Ziehrahmens 52 ist.2 and 3 show a strand pulling device for the
Die Unterseite des Ziehrahmens 52 ist schwalbenschwanzförmig 56
ausgebildet und beiderseits von im Grundrahmen 51 angeordneten
Wälzlagern 57 gehalten. Die Stränge 30 liegen auf einer gemeinsamen
unteren Klemmplatte 58 auf, die auf einem unteren Querjoch 59 des
Ziehrahmens 52 befestigt ist. Zur kraftschlüssigen Verbindung der
Stränge 30 mit dem Ziehrahmen 52 ist für jeden Strang eine eigene,
obere Klemmplatte 60 vorgesehen, die von je einem Klemmzylinder 53 gegen
den Strang gepreßt werden kann. Die Klemmzylinder 53 sind auf einem
oberen Querjoch 61 des Ziehrahmens 52 befestigt.The underside of the
Mit der vorbeschriebenen Strangauszieheinrichtung werden also
beispielsweise vier Stränge mit annähernd gleichem Querschnitt - dabei
sind unterschiedliche Querschnittsformen möglich, z.B. rund, quadratisch
oder dergl. - gleichsinnig und gleichzeitig durch Betätigung der
Ziehzylinder 54 bewegt, nachdem sie durch Anstellen der Klemmbacken 60
mittels der Klemmzylinder 53 kraftschlüssig in dem Ziehrahmen 52
gehalten werden. Die in Fig. 2 dargestellten, hintereinander
angeordneten Ziehaggregate bewegen sich gegenläufig, d. h. während ein
Ziehaggregat mit den Strängen kraftschlüssig verbunden die Förderarbeit
leistet, wird das andere Ziehaggregat in die Ausgangsposition
zurückbewegt. Das im Klemmbetrieb arbeitende, die Strangförderung
bewirkende Aggregat kann dabei gleichförmig oder schrittweise den Strang
bewegen, ebenso wie eine Rückstoßbewegung des Stranges in Richtung
Kokillen vorgenommen werden kann. Die Klemmzylinder 53 sind einzeln
steuerbar, so daß gemäß der Erfindung im Störfall an einzelnen Strängen
oder Kokillen der jeweils betroffene Strang bei der Ausziehbewegung
nicht mehr im Ziehaggregat festgeklemmt wird, sondern die Klemmbacken
lediglich nur bei der Rückstoßbewegung des Ziehrahmens 52 mit dem
betroffenen Strang verbunden sind. Durch die Rückstoßbewegung und dem
anschließenden Strangstillstand wird das Ausfließen der Schmelze aus der
Kokille bzw. im Strang verhindert und die übrigen Stränge werden
fertiggegossen.So with the above-described strand puller
for example four strands with approximately the same cross section - included
different cross-sectional shapes are possible, e.g. round, square
or the like - in the same direction and at the same time by pressing the
Die erfindungsgemäße Anlage bietet sich an, wenn größere Schmelzenmengen verarbeitet werden sollen oder wenn das Endprodukt besonders kleine Querschnittsflächen aufweisen soll, z.B. bei der Drahtherstellung. Die Vorteile sind dann in einer verbesserten Gefügeausbildung und in der geringeren Anzahl der Verarbeitungsstufen zu sehen.The system according to the invention is useful when larger amounts of melt to be processed or if the end product is particularly small Cross-sectional areas, e.g. in wire manufacturing. The Advantages are then in an improved structure and in to see a lower number of processing stages.
