Abstract

A pouring nozzle for an intermediate container of a strang casting device has a body part of a refractory material arranged in an opening of a bottom of the intermediate container, an elongated piece of refractory material associated with the body part and extending in the interior of the intermediate container, and a breakage point provided between the body part and the elongated piece at a height of the bottom of the intermediate container.

Description

Die Erfindung betrifft eine verlängerte Ausgußdüse für Zwischenbehälter in Stranggießanlagen, die aus feuerfestem Werkstoff besteht und die sich in den Zwischenbehälter erstreckt.The invention relates to an extended pouring nozzle for intermediate containers in continuous casting plants, which consists of refractory material and which extends into the intermediate container.

Eine Ausgußdüse mit diesen Merkmalen ist aus DE-A-2 626 986 bekannt, bei der das sich in den Zwischenbehälter erstreckende Verlängerungsstück als verbrauchbarer Rohrstutzen ausgebildet ist. Auf diese Weise soll sichergestellt werden, daß sich beim Angießen eine dünne, feste Metallhaut entfernt von der Ausgußöffnung bildet, durch die feuerfeste Verunreinigungen oder Schlackenreste zurückgehalten werden sollen, die andernfalls u. U. sofort zum Einfrieren oder »Blockieren« des Auslaufs führen könnten. Da sich der Rohrstutzen während der Benutzung wenigstens teilweise verbrauchen soll, und dieser Verbrauch in der Praxis nach Maßgabe der im Zwischenbehälter auf den Rohrstutzen einwirkenden Faktoren Zeit und Temperatur verläuft, bleibt der Grad der Entleerung des Zwischenbehälters nicht mehr direkt steuerbar bzw. beeinflußbar und ist daher mehr oder weniger zufallsbedingt, was dem wirtschaftlichen Prinzip des Stranggießens in hohem Maße widerspricht. Außerdem stellt der Rohrstutzen infolge seines verbrauchsbedingten Materialschwunds einen potentiellen Schlackenbildner dar, dessen Schadstoffe in feinstverteilter Form in den Strang eingehen und somit die Gußqualität in unerwünschter Weise beeinträchtigen.A pouring nozzle with these features is known from DE-A-2 626 986, in which the extension piece extending into the intermediate container is designed as a usable pipe socket. In this way it is to be ensured that a thin, solid metal skin forms away from the pouring opening during the casting process, by means of which refractory impurities or slag residues are to be retained, which may otherwise occur. This could immediately lead to the spout freezing or "blocking". Since the pipe socket is to be used up at least partially during use, and in practice this consumption depends on the factors of time and temperature acting on the pipe socket in the intermediate container, the degree of emptying of the intermediate container no longer remains directly controllable or can be influenced and is therefore possible more or less by chance, which strongly contradicts the economic principle of continuous casting. In addition, due to its material shrinkage due to its consumption, the pipe socket represents a potential slag generator, the pollutants of which enter the strand in finely divided form and thus adversely affect the casting quality.

Der Erfindung liegt die Aufgabe zugrunde, eine Ausgußdüse der gattungsgemäßen Art zu schaffen, die eine weitgehende störungsfreie und zeitlich steuerbare Angießphase beim Stranggießen gewährleistet.The invention has for its object to provide a pouring nozzle of the generic type, which ensures a largely trouble-free and time-controllable pouring phase during continuous casting.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Ausgußdüse auf Höhe des Bodens des Zwischenbehälters eine Sollbruchstelle vorgesehen ist und daß die Ausgußdüse der Sollbruchstelle benachbart zwei Teile aufweist, von denen das obere Teil nach dem Zerstören der Sollbruchstelle (Abtrennen) im Metallband aufsteigt und in der Badschlacke schwimmt.The object is achieved in that a predetermined breaking point is provided on the pouring nozzle at the level of the bottom of the intermediate container and that the pouring nozzle has two parts adjacent to the predetermined breaking point, of which the upper part rises in the metal band after the predetermined breaking point has been destroyed (cut off) and into the bath slag is swimming.

Mit Hilfe der Sollbruchstelle ist, z. B. nach Erreichen einer vorbestimmten Badspiegelhöhe, der Gießbeginn zeitlich exakt steuerbar. Infolge nur geringer Wärmeverluste kann die Schmelze ungehindert und vollständig abfließen. Das abgetrennte Verlängerungsstück der Ausgußdüse verbleibt nach dem Aufsteigen reaktionslos in der Badschlacke. Das Abtrennen kann auf einfache Weise entweder mittels Eisenstange oder mit einem stramm gewickelten Papprohr von ausreichender Länge durch das Stopfendeckelloch oder auch durch eine Öffnung in der Seitenwand des Zwischenbehälters durch leichten Stoß erfolgen.With the help of the predetermined breaking point, z. B. after reaching a predetermined bath level, the start of watering can be precisely controlled in time. As a result of only slight heat losses, the melt can flow away completely and unhindered. The separated extension piece of the pouring nozzle remains unreacted in the bath slag after rising. The separation can be carried out in a simple manner either by means of an iron rod or with a tightly wound cardboard tube of sufficient length through the plug cover hole, or also through an opening in the side wall of the intermediate container by light impact.

Durch den Einsatz der erfindungsgemäßen Ausgußdüse läßt sich eine Steigerung der Gießleistung nicht nur bei konventionellen Anlagen erzielen, sondern insbesondere auch bei sog. Vielstranganlagen, bei denen bekanntlich Zwillings- und/oder Drillingskokillen zu einem Block zusammengefaßt sind. Die in den jeweiligen Hubtischen zusammengefaßten Stranggieß-Kokillen können von Gießbeginn an gemeinsam oszillieren, und auch die Stränge können gemeinsam abgezogen werden, da die Stranggieß-Kokillen nahezu synchron mit gleichen Metallmengen störungsfrei versorgt werden können.By using the pouring nozzle according to the invention, an increase in the casting performance can be achieved not only in conventional systems, but in particular also in so-called multi-strand systems in which, as is known, twin and / or triple molds are combined to form a block. The continuous casting molds combined in the respective lifting tables can oscillate together from the start of casting, and the strands can also be pulled off together, since the continuous casting molds can be supplied with the same amount of metal almost synchronously and without interference.

Nach einer bevorzugten Ausgestaltung der Er findung kann die Ausgußdüse aus zwei Teilen bestehen, wobei zwischen beiden Teilen die Sollbruchstelle durch feuerfestes Bindemittel gebildet ist, dessen Wärmestandfestigkeit im Bereich der Liquidustemperatur der zu vergießenden Schmelze liegt. Die Ausgußdüse kann aber zweckmäßigerweise auch einstückig ausgebildet sein.According to a preferred embodiment of the invention, the pouring nozzle can consist of two parts, the predetermined breaking point being formed between the two parts by a refractory binder, the heat resistance of which is in the range of the liquidus temperature of the melt to be poured. The pouring nozzle can also be expediently formed in one piece.

Die Erfindung wird nachfolgend anhand der beigefügten Zeichnung näher erläutert. Es zeigt

  • Fig. 1 einen Teil einer Stranggießanlage mit einer Ausgußdüse gemäß der Erfindung in schematischer Darstellung;
  • Fig. 2 eine vergrößerte Schnittdarstellung der erfindungsgemäßen Ausgußdüse; und
  • Fig. 3 eine weitere Ausführungsform der Ausgußdüse.
The invention is explained in more detail below with reference to the accompanying drawing. It shows
  • Figure 1 shows a part of a continuous caster with a pouring nozzle according to the invention in a schematic representation.
  • 2 is an enlarged sectional view of the pouring nozzle according to the invention; and
  • Fig. 3 shows another embodiment of the pouring nozzle.

In Fig. 1 ist ein Teil einer Stranggießanlage üblicher Bauart dargestellt, bei der eine Gießpfanne 11 mit einer Schmelze 10 aus Stahl und darunter ein Zwischenbehälter 12 vorgesehen ist. Unterhalb des Bodenausgusses 13, mit verlängerter Ausgußdüse 14 und Schieber 15 ist eine wassergekühlte Stranggieß-Kokille 16 vorgesehen.In Fig. 1 a part of a continuous caster of conventional design is shown, in which a ladle 11 with a melt 10 made of steel and an intermediate container 12 is provided. A water-cooled continuous casting mold 16 is provided underneath the base spout 13, with an extended pouring nozzle 14 and slide 15.

Die verlängerte Ausgußdüse 14, die aus einem stark tonerdehaltigen, feuerfesten Material besteht, setzt sich aus einem unteren Teil 17 und einem oberen Teil 18 zusammen, die vorzugsweise einstückig ausgebildet sind (Fig. 2). An der Übergangsstelle der beiden Teile 17, 18 ist eine Sollbruchstelle in Form eines kerbförmigen Brecherrings 19 ausgebildet. Die Länge des unteren Teils 17 der Ausgußdüse 14 entspricht im wesentlichen der einer herkömmlichen Ausgußdüse, deren eines Ende im eingebauten Zustand etwa 20 bis 30 mm über den Zwischenbehälterboden herausragt. Die Gesamtlänge der auf diese Weise verlängerten Ausgußdüse 14 richtet sich nach der gewünschten Badspiegelhöhe, wobei in der Praxis für das obere Teil 18 eine Länge von ca. 200 mm ausreichend sein dürfte.The extended pouring nozzle 14, which consists of a high alumina, refractory material, is composed of a lower part 17 and an upper part 18, which are preferably formed in one piece (Fig. 2). A predetermined breaking point in the form of a notch-shaped crusher ring 19 is formed at the transition point of the two parts 17, 18. The length of the lower part 17 of the pouring nozzle 14 corresponds essentially to that of a conventional pouring nozzle, one end of which protrudes about 20 to 30 mm above the bottom of the intermediate container in the installed state. The total length of the pouring nozzle 14, which is extended in this way, depends on the desired bath level, although in practice a length of approximately 200 mm should be sufficient for the upper part 18.

Fig. 3 zeigt eine weitere Ausführungsform einer verlängerten Ausgußdüse 20, die jedoch im Gegensatz zu der zuvor beschriebenen zweiteilig ausgebildet ist. Der untere Teil 21 und der obere Teil 22 sind durch ein feuerfestes Bindemittel 23 stumpfflächig miteinander verbunden, das wiederum eine Sollbruchstelle zwischen den beiden Teilen bildet und dessen Wärmestandfestigkeit im Bereich der Liquidustemperatur der zu vergießenden Schmelze liegt. Dabei kommt es darauf an, daß sich die Sollbruchstelle möglichst erst dann löst, wenn die gewünschte Badspiegelhöhe im Zwischenbehälter erreicht ist. Eine höhere Wärmestandfestigkeit des eingesetzten Bindemittels gewährleistet eine längere Verweilzeit der Schmelze vor dem Angießen im Verteiler, so daß unerwünschte Metallbegleiter in die Schlakkenzone aufsteigen können.Fig. 3 shows a further embodiment of an extended pouring nozzle 20, which, however, is formed in two parts in contrast to the previously described. The lower part 21 and the upper part 22 are connected to each other by a fire-resistant binder 23, which in turn forms a predetermined breaking point between the two parts and whose heat resistance lies in the range of the liquidus temperature of the melt to be cast. It is important that the predetermined breaking point is as possible then triggers when the desired bath level in the intermediate container is reached. A higher heat resistance of the binder used ensures a longer residence time of the melt before casting in the distributor, so that undesired metal companions can rise into the slag zone.

Als Werkstoff für das Bindemittel können Heißkleber oder andere geeignete kohlenstoffhaltige Ausbrennstoffe verwendet werden, die bei Erreichen der vorbestimmten Temperatur den oberen Teil 22 selbsttätig freigeben. Eine vergleichbar gute Wirkung läßt sich auch mit Hilfe solcher Stoffe erzielen, die sich aufgrund ihrer thermischen Eigenschaften beim Brand ausdehnen und auf diese Weise das obere Verlängerungsstück abstoßen.Hot glue or other suitable carbon-containing burn-out materials can be used as the material for the binder, which automatically release the upper part 22 when the predetermined temperature is reached. A comparably good effect can also be achieved with the help of substances that expand due to their thermal properties during a fire and thus repel the upper extension piece.

Obwohl die vorliegende Erfindung ausschließlich im Zusammenhang mit einer schiebergesteuerten Stranggießanlage beschrieben worden ist, kann ihr Gegenstand selbstverständlich auch bei »offen« arbeitenden Anlagen eingesetzt werden.Although the present invention has only been described in connection with a slide-controlled continuous casting installation, its object can of course also be used in "open" installations.
