Description

Die Erfindung betrifft ein Verfahren zum Einbringen eines Anfahrstrangkopfes eines Anfahrstranges in die Durchlaufkokille einer Horizontalstranggießanlage sowie eine Horizontalstranggießanlage zur Durchführung des Verfahrens.The invention relates to a method for introducing a starting strand head of a starting strand into the continuous mold of a horizontal continuous casting installation and a horizontal continuous casting installation for carrying out the method.

Bei einer Horizontalstranggießanlage mit einer an einem Verteilergefäß befestigten Durchlaufkokille stellt das Einführen des Anfahrstranges in die Kokille eine problematische Arbeit dar, u. zw. aus mehreren Gründen. Die am Verteilergefäß lösbar montierte Kokille nimmt je nach Lage des Verteilergefäßes unterschiedliche Lagen gegenüber der ortsfesten Strangführung ein, so daß der über die ortsfeste Strangführung in die Kokille eingeschobene Anfahrstrang nicht genau mit dem Kokillenhohlraum fluchtet. Es ist notwendig, den Anfahrstrang, insbesondere den Anfahrstrangkopf, leicht anzuheben bzw. abzusenken, um eine Kollision des Anfahrstrangkopfes mit den Kokillenseitenwänden zu vermeiden. Da die Kokille am Verteilergefäß befestigt ist, läßt sich nach dem Einfädeln des Anfahrstrangkopfes in die Kokille die am Anfahrstrangkopf befestigte Dichtung nicht mehr kontrollieren. Beschädigungen dieser Dichtung können nicht mehr festgestellt werden, und es ist die Gefahr gegeben, daß ein Strangdurchbruch zu Gießbeginn erfolgt, wenn es beim Einfädeln des Anfahrstrangkopfes in die Kokille zu einem Anstoßen des Kopfes an einer Seitenwandkante gekommen ist.In a horizontal continuous casting machine with a continuous mold attached to a distributor vessel, the introduction of the starting strand into the mold is problematic work, u. for several reasons. Depending on the position of the distributor vessel, the mold, which is detachably mounted on the distributor vessel, occupies different positions relative to the stationary strand guide, so that the start-up strand inserted into the mold via the stationary strand guide does not exactly align with the mold cavity. It is necessary to slightly raise or lower the start-up line, in particular the start-up line head, in order to avoid a collision of the start-up line head with the mold side walls. Since the mold is attached to the distributor vessel, the thread attached to the start-up strand head can no longer be checked after the start-up strand head has been threaded into the mold. Damage to this seal can no longer be ascertained, and there is a risk that a strand breakthrough will occur at the start of the casting if the head bumps against a side wall edge when the start-up strand head is threaded into the mold.

Infolge der an die Kokille bei Horizontalstranggießanlagen anschließenden Nachkühler ist ein Beobachten des Einfädelvorganges des Anfahrstrangkopfes in die Kokille nicht möglich. Außerdem muß infolge dieser Nachkühler der Anfahrstrangkopf relativ weit weg von der Kokille zum Zweck des Hebens bzw. Senkens beim Einfädelvorgang angefaßt werden, wodurch die Schwierigkeiten beim Einfädeln noch weiter vergrößert werden.As a result of the aftercooler connected to the mold in horizontal continuous casting plants, it is not possible to observe the threading process of the start-up strand head into the mold. In addition, as a result of these aftercoolers, the start-up strand head must be handled relatively far away from the mold for the purpose of lifting or lowering during the threading process, which further increases the difficulties in threading.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, ein Verfahren der eingangs beschriebenen Art bzw. eine Anlage zur Durchführung des Verfahrens zu schaffen, welche ein leichtes und sicheres Einfädeln des Anfahrstrangkopfes in die Kokille ermöglichen, wobei Beschädigungen der Anfahrstrangkopfdichtung sowie der Kokillenseitenwände zuverlässig vermieden werden und eine Kontrolle der Dichtung des in die Kokille eingesetzten Anfahrstrangkopfes möglich ist.The invention aims to avoid these disadvantages and difficulties and has as its object to provide a method of the type described above or a system for carrying out the method, which enable easy and safe threading of the starting strand head into the mold, with damage to the starting strand head gasket and of the mold side walls can be reliably avoided and the seal of the starting strand head inserted into the mold can be checked.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kokille aus der Stranggießanlage ausgebaut und vertikal gestellt wird, worauf der vom Anfahrstrang getrennte Anfahrstrangkopf in die Kokille eingefädelt und in seiner Lage gegenüber der Kokille fixiert wird, daß weiters die Kokille gemeinsam mit dem an ihr fixierten Anfahrstrangkopf in die Stranggießanlage eingebaut, insbesondere an einem Verteilergefäß befestigt wird, und daß sodann der Anfahrstrangkopf mit dem in der Strangführung liegenden Anfahrstrang gekuppelt wird, worauf die Fixierung des Anfahrstrangkopfes gelöst wird.This object is achieved in that the mold is removed from the continuous caster and placed vertically, whereupon the starting strand head separated from the starting strand is threaded into the mold and fixed in position with respect to the mold, that further the mold together with the starting strand head fixed to it installed in the continuous caster, in particular fastened to a distributor vessel, and that the starting strand head is then coupled to the starting strand lying in the strand guide, whereupon the fixing of the starting strand head is released.

Bei einer mit einem Nachkühler ausgestatteten Kokille wird vorteilhaft der Nachkühler gemeinsam mit der Kokille zum Zweck des Einbringens des Anfahrstrangkopfes ausgebaut.In the case of a mold equipped with an aftercooler, the aftercooler is advantageously removed together with the mold for the purpose of introducing the start-up strand head.

Zweckmäßig wird der Anfahrstrangkopf an dem Nachkühler mittels eines Bolzens fixiert.The starting strand head is expediently fixed to the aftercooler by means of a bolt.

Um den Anfahrstrang an den Anfahrstrangkopf in einfacher Weise kuppeln zu können, ohne diese beiden Teile beim Kuppeln genau gegeneinander ausrichten zu müssen, wird der Anfahrstrangkopf mit dem Anfahrstrang mittels eines diese beiden Teile durchsetzenden konischen Verbindungsbolzens gekuppelt.In order to be able to couple the start-up line to the start-up line head in a simple manner, without having to align these two parts exactly with one another when coupling, the start-up line head is coupled to the start-up line by means of a conical connecting bolt passing through these two parts.

Eine Horizontalstranggießanlage zur Durchführung des erfindungsgemäßen Verfahrens mit einem Verteilergefäß, einer an dessen Ausgießöffnung lösbar montierten Durchlaufkokille und einer daran anschließenden, Kühlplatten aufweisenden Nachkühleinrichtung und mit einem Anfahrstrang mit einem eine Dichtung aufweisenden Anfahrstrangkopf ist dadurch gekennzeichnet, daß der Anfahrstrangkopf eine größere Längserstreckung aufweist als die Nachkühleinrichtung, wobei ein Ende in den Kokillenhohlraum ragt und das andere Ende außerhalb der Nachkühleinrichtung mit dem Anfahrstrang kuppelbar ist und wobei eine Fixiereinrichtung für den in die Kokille eingeführten Anfahrstrangkopf vorgesehen ist.A horizontal continuous caster for carrying out the method according to the invention with a distributor vessel, a continuous mold which is detachably mounted on its pouring opening and a subsequent cooling device having cooling plates, and with a starting line with a starting line head having a seal is characterized in that the starting line head has a greater longitudinal extent than the after-cooling device , wherein one end protrudes into the mold cavity and the other end can be coupled outside of the after-cooling device with the start-up line and wherein a fixing device is provided for the start-up line head inserted into the mold.

Die Erfindung ist nachfolgend anhand der Zeichnung näher erläutert, wobei Fig. 1 eine Horizontalstranggießanlage im Schnitt in schematischer Darstellung zeigt. Fig. 2 veranschaulicht einen Schnitt gemäß der Linie II-II der Fig. in vergrößertem Maßstab.The invention is explained in more detail below with reference to the drawing, in which Fig. 1 shows a horizontal continuous caster in section in a schematic representation. Fig. 2 illustrates a section along the line II-II of Fig. In an enlarged scale.

Ein Verteilergefäß 1 ist entlang von Schienen 2 mitsamt einer an ihm an der Ausgießöffnung 3 befestigten Durchlaufkokille 4 quer zur Längsrichtung 5 der Strangführungsbahn 6 verfahrbar, so daß die Kokille 4 mitsamt dem Verteilergefäß 1 leicht austauschbar ist. Zwischen der Kokille 4 und dem Verteilergefäß 1 sind ein Dichtkörper 7 sowie ein Schieber 8 vorgesehen.A distributor vessel 1 can be moved along rails 2 together with a continuous mold 4 fastened to it at the pouring opening 3 transversely to the longitudinal direction 5 of the strand guideway 6, so that the mold 4 together with the distributor vessel 1 is easily exchangeable. A sealing body 7 and a slide 8 are provided between the mold 4 and the distributor vessel 1.

Die Kokille 4 selbst weist einen wassergekühlten, den eigentlichen Kokillenhohlraum 9 bildenden Teil auf, an dem Kühlplatten 11 aufweisende Nachkühler 10 angeschlossen sind, deren Kühlplatten gegen die Strangoberfläche mittels Druckmittelzylinder 12 anstellbar sind. Am auslaufseitigen Ende des zweiten Nachkühlers 10 sind Rollen 13 vorgesehen, die nicht angetrieben sind und der Grobzentrierung des Stranges bzw. eines Anfahrstranges 14 dienen. Mit 15 sind die Rollen der Strangführung bezeichnet. Der Anfahrstrang 14 besteht aus einer Anfahrstange 16 und einem an dieser Anfahrstange lösbar befestigten Anfahrstrangkopf 17, der an seinen vorderen, in die Kokille ragenden Ende mit einer Dichtung 18 versehen ist.The mold 4 itself has a water-cooled part which forms the actual mold cavity 9, to which aftercoolers 10 having cooling plates 11 are connected, the cooling plates of which can be adjusted against the strand surface by means of pressure medium cylinders 12. At the outlet end of the second aftercooler 10, rollers 13 are provided, which are not driven and serve to roughly center the strand or a starting strand 14. With 15 the roles of strand guidance are designated. The start-up line 14 consists of a start-up rod 16 and a start-up line head 17 which is detachably fastened to this start-up rod and which is provided with a seal 18 at its front end which projects into the mold.

Bisher mußte beim Einfädeln des Anfahrstrangkopfes in-die Kokille die fluchtende Lage des Anfahrstrangkopfes 17 zum Kokillenhohlraum 9 durch Heben oder Senken des Anfahrstrangkopfes (manuell oder mittels eines Kranes) bewerkstelligt werden, was eine schwierige Arbeit darstellt, bei welcher sich Kollisionen des Anfahrstrangkopfes mit den Kanten 19 der Kokillenseitenwände 20 nicht vermeiden lassen.Previously, the threading position of the Starting strand head 17 to the mold cavity 9 can be accomplished by lifting or lowering the starting strand head (manually or by means of a crane), which is a difficult job in which collisions of the starting strand head with the edges 19 of the mold side walls 20 cannot be avoided.

Erfindungsgemäß ist der Anfahrstrangkopf 17 an der Anfahrstrange 16 lösbar befestigt, wobei die Trennstelle - bei in die Kokille eingefädeltem Anfahrstrangkopf 17-außerhalb der Nachkühler 10, also zwischen Nachkühler 10 und der Strangführung 6 liegt. Der Anfahrstrangkopf weist eine Länge auf, die größer ist als die Längserstreckung der Nachkühler 10, so daß er durch den Nachkühler nach außen ragt.According to the invention, the start-up strand head 17 is detachably fastened to the start-up strand 16, the separation point — when the start-up strand head 17 is threaded into the mold — lies outside the aftercooler 10, that is to say between the aftercooler 10 and the strand guide 6. The start-up strand head has a length that is greater than the longitudinal extent of the aftercooler 10, so that it projects outward through the aftercooler.

Weiters weist der Anfahrstrangkopf 17 eine Einrichtung zum Fixieren an der Kokille 4 bzw. an den Nachkühlern 10 auf. Im dargestellten Ausführungsbeispiel ist diese Einrichtung als im Anfahrstrangkopf vorgesehenes Loch 21 ausgebildet, durch welches ein Bolzen 22 gesteckt werden kann, der seitlich des Anfahrstrangkopfes liegende, die Rollen 13 tragende Platten 23 ebenfalls durchsetzt. Dieser Bolzen 22 weist ein Sicherungsblech 24 auf, welches bei einer halben Umdrehung des Bolzens außer Eingriff mit einer an einem der Bleche 23 angeordneten Klammer 25 kommt.Furthermore, the start-up strand head 17 has a device for fixing to the mold 4 or to the aftercoolers 10. In the exemplary embodiment shown, this device is designed as a hole 21 provided in the start-up strand head, through which a bolt 22 can be inserted, which also passes through plates 23 lying on the side of the start-up strand head and carrying the rollers 13. This bolt 22 has a locking plate 24, which comes out of engagement with a clamp 25 arranged on one of the plates 23 at half a rotation of the bolt.

Zur Verbindung des Anfahrstrangkopfes 17 mit der Anfahrstange 16 ist an einander überlappenden Fortsätzen 26, 27 dieser Teile eine konische Bohrung 28 vorgesehen, in die ein konischer Verbindungsbolzen 29 einsetzbar ist. Durch das Einsetzen dieses Verbindungsbolzens 29 werden der Anfahrstrangkopf 17 und die Anfahrstrange 16 gegeneinander ausgerichtet. Ein den konischen Verbindungsbolzen 29 durchsetzender Schraubenbolzen 30 dient zum Fixieren des konischen Verbindungsbolzens 29.To connect the start-up strand head 17 to the start-up rod 16, a conical bore 28 is provided on overlapping extensions 26, 27 of these parts, into which a conical connecting bolt 29 can be inserted. By inserting this connecting bolt 29, the start strand head 17 and the start strand 16 are aligned with each other. A screw bolt 30 passing through the conical connecting bolt 29 serves to fix the conical connecting bolt 29.

Die Funktion der Einrichtung ist folgende :

  • Vor dem Einfädeln des Anfahrstrangkopfes 17 in die Kokille 4 wird die Kokille 4 aus der Stranggießanlage ausgebaut. Ein Ausbau der Kokille ist bei Horizontalstranggießanlage des öfteren notwendig, da der Dichtkörper 7 sowie der Schieber 8 hoch beanspruchte Verschleißteile darstellen, deren Austausch des öfteren zu erfolgen hat. Und zwar wird die Kokille 4 gemeinsam mit den an ihr montierten Nachkühlern 10 ausgebaut und in vertikale Lage geschwenkt. Sodann wird der Anfahrstrangkopf 17, der zuvor von der Anfahrstrange 16 getrennt wurde, in die Kokille eingefädelt, welche Manipulation einfach durchzuführen ist, da der vertikal an einem Kran hängende Anfahrstrangkopf 17 leicht in eine mit dem Kokillenhohlraum 9 fluchtende Lage eingependelt werden kann. Zur Erleichterung dieses Vorganges könnte beispielsweise ein den Anfahrstrangkopf ausrichtender Einführtrichter vorgesehen sein, der an die Kokille ansetzbar ist.
The function of the facility is as follows:
  • Before threading the start-up strand head 17 into the mold 4, the mold 4 is removed from the continuous casting plant. An expansion of the mold is often necessary in the case of horizontal continuous casting machines, since the sealing body 7 and the slide 8 represent highly stressed wear parts, which must be replaced frequently. Specifically, the mold 4 is removed together with the aftercoolers 10 mounted on it and pivoted into a vertical position. Then the start-up strand head 17, which was previously separated from the start-up strand 16, is threaded into the mold, which manipulation is easy to carry out, since the start-up strand head 17 hanging vertically on a crane can easily be leveled into a position aligned with the mold cavity 9. To facilitate this process, for example, an insertion funnel that aligns the start-up strand head could be provided, which can be attached to the mold.

Bei diesem Vorgang sind die Platten 11 der Nachkühler 10, wie in Fig. veranschaulicht, in zurückgezogener, vom Strang abgehobener Lage fixiert. Nach dem Einfädeln des Anfahrstrangkopfes 17 wird der Kopf durch Einsetzen des Bolzens 22 an der Baueinheit Kokille-Nachkühler 4, 10 fixiert. Sodann wird die Kokille 4 gemeinsam mit dem an ihr fixierten Anfahrstrangkopf 17 in die Stranggießanlage eingebaut, d. h. an dem Verteilergefäß 1 montiert, worauf die Anfahrstrange-16 durch Einsetzen des konischen Verbindungsbolzens 29 mit dem Anfahrstrangkopf 17 gekuppelt wird. Nach Entfernen des Bolzens 22 kann mit dem Gießen, d. h. dem Ausziehen des Anfahrstrangkopfes 17 aus der Kokille 4 begonnen werden.During this process, the plates 11 of the aftercooler 10, as illustrated in FIG. 1, are fixed in a retracted position which is lifted off the strand. After threading the start-up strand head 17, the head is fixed on the mold-aftercooler 4, 10 by inserting the bolt 22. Then the mold 4 is installed together with the start-up strand head 17 fixed to it in the continuous casting installation, i. H. mounted on the distributor vessel 1, whereupon the start-up line 16 is coupled to the start-up line head 17 by inserting the conical connecting bolt 29. After removal of the pin 22, casting, i.e. H. the pulling of the starting strand head 17 from the mold 4 can be started.

Die Erfindung beschränkt sich nicht auf das dargestellte Ausführungsbeispiel, sondern sie kann in verschiedener Hinsicht im Rahmen der Ansprüche modifiziert werden. Die Einrichtung zum Fixieren des Anfahrstrangkopfes an der Kokille kann auch eine Klemmeinrichtung sein ; beispielsweise ist es möglich, den Anfahrstrangkopf in der Kokille durch Klemmen zwischen den Platten 11 des Nachkühlers 10 zu halten.The invention is not limited to the exemplary embodiment shown, but can be modified in various ways within the scope of the claims. The device for fixing the starting strand head to the mold can also be a clamping device; for example, it is possible to hold the start-up strand head in the mold by clamping between the plates 11 of the aftercooler 10.
