Abstract
Description
Die Erfindung betrifft eine Verbundgußplatte für das Stranggießen zur Anordnung im Bereich der Kokille.The invention relates to a composite cast plate for continuous casting for arrangement in the region of the mold.
Eine derartige Verbundgußplatte ist beispielsweise aus der DE 18 09 997 U1 bekannt.Such a composite cast plate is known for example from DE 18 09 997 U1.
Die DE 195 04 949 U1 beschreibt ein Verfahren zur Herstellung eines Verbundgußteils aus mehreren metallischen Werkstoffen mit metallischer Matrix in einer Gießform, bei dem an einen oder mehreren in den Formhohlraum einzubringenden Körpern deren spätere Kontaktflächen vor dem Gießvorgang mit einem Überzug versehen werden, eine Schmelze oder mehrere Schmelzen gleichzeitig angegossen werden.DE 195 04 949 U1 describes a method for producing a composite casting of a plurality of metallic materials with a metallic matrix in a casting mold, in which one or more bodies to be introduced into the mold cavity whose later contact surfaces are provided with a coating before the casting, a melt or several melts are poured simultaneously.
Zum Start des Stranggußvorgangs benötigt man in der Kupferkokille einen Anfahrkopf. Dieser hat eine bestimmte Formgebung, damit ein Kraftschluß mit dem abgekühlten Flüssigstahl erfolgen kann und das Stranggießen beginnt.To start the Stranggußvorgangs needed in the copper mold a head. This has a certain shape, so that a frictional connection can be made with the cooled liquid steel and the continuous casting begins.
Der Freiraum zwischen dem Kaltstrang-Anfahrkopf und der Kokille wurde bisher mittels einer Feuerfestschnur oder mit sonstigen Materialien abgedichtet. Dies ist zum einen zeitaufwendig und zum anderen besteht hierbei die Gefahr eines Durchbruchs.The space between the dummy bar approach head and the mold has hitherto been sealed by means of a refractory cord or other materials. On the one hand, this is time-consuming and, on the other hand, there is the danger of a breakthrough.
Bei einem Verbundguß - einem Gießstopp mit Verteilerwechsel oder bei Stahl-Qualitätswechsel - benötigt man ebenso einen Anfahrkopf, der die Verbindung herstellt zwischen dem zuletzt gegossenen, noch flüssigen Stahl und dem neu anzugießenden Stahl. Das diese Funktion übemehmende Element wird als Verbundgußplatte bezeichnet. Sie besteht vorzugsweise aus Stahl.In a composite casting - a casting stop with distributor change or steel quality change - you also need a dummy head, which establishes the connection between the last cast, still liquid steel and the newly zuzugießenden steel. The element taking over this function is called a composite cast plate. It is preferably made of steel.
Aufgabe der Erfindung ist cs, Durchbrüche und die dadurch hervorgerufenen Anlagenstillstände zu vermeiden.The object of the invention is cs to avoid breakthroughs and the resulting plant downtime.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verbundgußplatte eine umlaufende Dichtung aufweist.This object is achieved in that the composite cast plate has a circumferential seal.
Die Dichtung verhindert das Durchlaufen von Stahl zwischen Kokille und Wannstrang.The seal prevents the passage of steel between the mold and the tubing strand.
Durch die erfindungsgemäße Maßnahme wird es beispielsweise möglich, auf einer Beam-Blank-Stranggießanlage Verbundguß durchzuführen, was bisher nicht machbar war. Jedoch auch bei anderen Stranggießanlagen, wie Bramme-, Vorblock- oder Knüppel-Stranggießanlagen kann die erfindungsgemäße Verbundgußplattc ebenfalls zum Einsatz kammen.The measure according to the invention makes it possible, for example, to carry out composite casting on a beam blank continuous casting plant, which was hitherto not feasible. However, in other continuous casters, such as slab, billet or billet continuous casting the Verbundgußplattc invention can also be used.
Durch die Erfindung wird ein kontinuierliches Gießen ohne Gießpause möglich, wodurch die Anlagenverfügbarkeit und eine höhere Wirtschaftlichkeit erreicht werden. Auch wird die Betriebssicherheit gesteigert.Through the invention, a continuous casting without casting pause is possible, whereby the plant availability and higher efficiency can be achieved. Also, the reliability is increased.
Eine Weiterbildung der Erfindung besteht darin, daß beidseits der Verbundgußplatte und im wesentlichen senkrecht zu dieser je mindestens ein, vorzugsweise zwei Rohrstutzen angeordnet sind.A further development of the invention consists in that at least one, preferably two, pipe sockets are arranged on both sides of the composite cast plate and substantially perpendicular to it.
Hierbei ist es vorteilhaft, daß die Rohrstutzen jeweils mindestens eine Bohrung aufweisen.It is advantageous that the pipe socket each have at least one bore.
Durch die Rohrstutzen mit den Bohrungen wird ein Kraftschluß zwischen der Vcrbundgußplatte und dem jeweils anliegenden flüssigen Metall geschaffen.Through the pipe socket with the holes a frictional connection between the Vcrbundgußplatte and the respective adjacent liquid metal is created.
Weiterhin ist es zweckmäßig, daß an der dem Strang zugewandten Seite der Rohrstutzen eine Spitze vorgesehen ist.Furthermore, it is expedient that a tip is provided on the strand side facing the pipe socket.
Verbundgußplatte gemäß Anspruch 1, dadurch gekennzeichnet, daß auf der der Kokille zugewandten Seite mindestens eine, vorzugsweise vier Büchsen angeordnet sind.Composite cast plate according to claim 1, characterized in that on the side facing the mold at least one, preferably four cans are arranged.
Auch diese Büchsen dienen dazu, den Kraftschluß zwischen der Verbundgußplatte und dem flüssigen Metall zu erhöhen.These cans also serve to increase the adhesion between the composite cast plate and the liquid metal.
Nachfolgend wird eine beispielhafte Ausgestaltung der Erfindung anhand von Zeichnungen erläutert.Hereinafter, an exemplary embodiment of the invention will be explained with reference to drawings.

Wie aus den Figuren zu entnehmen ist, besteht die Verbundgußplatte aus einem flächigen Element 1, das eine umlaufende Dichtung aufweist.As can be seen from the figures, the composite cast plate consists of a flat element 1, which has a circumferential seal.
Beidseits der Verbundgußplatte 1 und im wesentlichen senkrecht zu dieser sind zwei Rohrstutzen 2 angeordnet, die jeweils mindestens eine Bohrung 3 aufweisen. Der Rohrstutzen 2 an der dem Strang zugewandten Seite A weist eine Spitze 4 auf. Auf der der Kokille zugewandten Seite B weist die Verbundgußplatte 1 vier Büchsen 5 auf.On both sides of the composite cast plate 1 and substantially perpendicular to this two
Sowohl die Rohrstutzen 2 mit den Bohrungen 3 als auch die Büchsen 5 dienen der Erhöhung des Kraftschlusses zwischen der Verbundgußplatte 1 und dem anliegenden flüssigen Metall.Both the
Der Verbundguß mit einer erfindungsgemäßen Verbundgußplatte 1 zeichnet sich durch die folgenden Schritte aus:
- Nach Ende einer Sequenz wird der im Feuerfestmaterial verschlissene Verteiler aus der Gießposition gefahren. Die Warmstränge werden gestoppt, um die Verbundgußplatte in die Kokille setzen zu können.
- Der Warmstrang wird in der Kokille heruntergefahren. Es wird Kühlschrott eingesetzt.
- Danach wird der neue, vorgchcizte Verteilerwagen über die Kokille gefahren. Er wird mit Flüssigstahl befüllt und bei ausreichendem Verteilerinhalt die Stränge werden neu angegossen.
- Nach Erreichen des Gießspiegels in der Kokille werden die Stränge angefahren.
- After the end of a sequence, the distributor worn in the refractory material is moved out of the casting position. The hot strands are stopped in order to put the composite cast plate in the mold.
- The hot strand is shut down in the mold. It is used cooling scrap.
- Then the new, vorgchcizte distribution car is driven over the mold. It is filled with liquid steel and with sufficient distributor contents the strands are newly cast.
- After reaching the pouring mirror in the mold, the strands are started.
Durch die Verwendung erfindungsgemäßer Verbundgußplatten, die das Durchlaufen von Stahl zwischen Kokille und Warmstrang verhindern, könncn Durchbrüche, die Betriebsstillstände hervorrufen, vermieden werden.By using composite cast plates according to the invention, which prevent the passage of steel between the mold and the hot strand, breakthroughs which cause downtimes can be avoided.
