Description
Die Erfindung betrifft einen Stopfen für ein Gießgefäß mit Bodenauslaßöffnung und befaßt sich insbesondere mit der Verbindung von Stopfenkopf und Stopfenstange.The invention relates to a stopper for a bottom outlet pouring vessel and is particularly concerned with it with the connection of stopper head and stopper rod.
Es ist bekannt, Stopfenkopf und Stopfenstange unmittelbar miteinander zu verbinden, indem entweder die Stopfenstange mit einem Gewindefortsatz in den Stopfenkopf eingeschraubt oder mit quer zur Stangenachse verlaufenden Zapfen versehen wird, die bajonettverschlußartig in entsprechende Ausnehmungen des Stopfenkopfes eingreifen. Stopfenstangen mit Gewindefortsatz sind verhältnismäßig teuer. Unter den während des Gießens auftretenden hohen thermischen und mechanischen Beanspruchungen wird der metallische Gewindefortsatz leicht verformt und hierdurch unbrauchbar. Da es im praktischen Betrieb nicht möglich ist, genaue Gewindepassungen zwischen dem metallischen Gewindefortsatz und dem aus feuerfestem Material bestehenden Stopfenkopf einzuhalten, treten häufig örtliche Beanspruchungskonzentrationen auf. Eine unmittelbare bajonettverschlußartige Verbindung von Stopfenkopf und Stopfenstange führt bei den verhältnismäßig kleinen tragenden Flächen oftmals zu übermäßigen Beanspruchungen der metallischen Querzapfen und/oder des Kopfes. Bekannte metallische Auskleidungen des Kopfes, die ein Ausbrechen des feuerfesten Materials an den Angriffssiellen der Zapfen verhindern sollen, sind aufwendig.It is known to connect the stopper head and stopper rod directly to one another by either the stopper rod is screwed into the stopper head with a thread extension or at right angles to the rod axis extending pin is provided, the bayonet lock-like in corresponding recesses of the stopper head. Plug rods with a threaded extension are relatively expensive. Under the The high thermal and mechanical stresses that occur during casting become the metallic Thread extension slightly deformed and therefore unusable. Since it is not possible in practical operation is, precise thread fits between the metallic thread extension and that of refractory In order to comply with the existing plug head, local stress concentrations often occur on. A direct bayonet-like connection of the stopper head and stopper rod leads to the relatively small load-bearing surfaces often lead to excessive stresses on the metallic ones Transverse pin and / or the head. Known metallic linings of the head that break out to prevent the refractory material from attacking the pegs are expensive.
Die geschilderten Nachteile werden bei einem Stopfen für ein Gießgefäß mit Bodenauslaßöffnung mit einem Stopfenkopf, der eine Bohrung aufweist zur Aufnahme einer Stopfenstange, die an ihrem Ende einen Bund hat, nach der Erfindung vermieden durch ein Sperrstück, das die Verbindung zwischen dem Bund der Stange und dem Stopfenkopf herstellt und nach oder mit dem Einlassen der Stange in die Bohrung des Kopfes eingesetzt wird.The disadvantages outlined are in the case of a stopper for a casting vessel with a bottom outlet opening with a stopper head which has a bore for receiving a stopper rod at its end has a covenant, avoided according to the invention by a locking piece that the connection between the Manufactures collar of the rod and the plug head and after or with the insertion of the rod into the bore of the head is used.
Dadurch, daß Stopfenkopf und Stopfenstange nicht unmittelbar, sondern über das Sperrstück miteinanander
verbunden werden, ergibt sich eine gewisse Beweglichkeit des Stopfenkopfes gegen die Stopfenstange,
wodurch eine gleichmäßige Verteilung der Belastung auf den Kopf erfolgt und beim Eingießen des
Stahls in das Gießgefäß, z. B. die Gießpfanne, keine örtlichen Beanspruchungskonzentrationen entstehen.
Gegenüber einer Stopfenstange mit Gewindefortsatz ist eine solche mit Bund erheblich billiger und unempfindlicher.
Der Bund kann beispielsweise die Form zahnförmiger Vorsprünge haben, ist vorzugsweise
jedoch ein rings um die Stange laufender Flansch, trägt also auf dem vollen Kreisumfang. Er kann durch
Anbringen einer entsprechend bemessenen Platte am Stopfen für ein Gießgefäß
mit BodenauslaßöffnungThe fact that the stopper head and stopper rod are not connected directly, but via the locking piece, results in a certain mobility of the stopper head against the stopper rod, whereby an even distribution of the load on the head takes place and when the steel is poured into the casting vessel, e.g. B. the ladle, no local stress concentrations arise. Compared to a stopper rod with a threaded extension, one with a collar is considerably cheaper and less sensitive. The collar can, for example, have the form of tooth-shaped projections, but is preferably a flange running around the rod, that is to say carries over the full circumference. He can by attaching an appropriately sized plate to the stopper for a pouring vessel
with bottom outlet opening

Sperrstück und Stopfenkopf weisen in weiterer Ausgestaltung der Erfindung Schultern auf, die nach Einführen des Sperstücks in den Kopf durch Verdrehen bajonettverschlußartig miteinander verriegelt werden.Locking piece and stopper head have a further embodiment of the invention shoulders after inserting the sparpiece into the head by twisting it be locked together like a bayonet lock.
In die freien Schlitze zwischen den Schultern des Stopfenkopfes kann zweckmäßig ein Sicherungskeil eingeschoben werden, der ein Verdrehen des Sperrstücks verhindert. Vorteilhafterweise bestehen das Sperrstück und gegebenenfalls der Sicherungskeil aus feuerfestem Material.A safety wedge can expediently be inserted into the free slots between the shoulders of the stopper head be inserted, which prevents twisting of the locking piece. Advantageously, they exist Locking piece and, if necessary, the safety wedge made of refractory material.
Entsprechend einer abgewandelten Ausführungsform der Erfindung wird die Verbindung zwischen dem Bund der Stange und dem Stopfenkopf mittels eines ein- oder mehrteiligen Sperrstücks mit Außengewinde hergestellt, das nach oder mit dem Einlassen der Stange in ein entsprechendes Innengewinde des Stopfenkopfes eingeschraubt wird.According to a modified embodiment of the invention, the connection between the collar of the rod and the plug head by means of a one-part or multi-part locking piece with an external thread produced, which after or with the letting of the rod in a corresponding internal thread of the Plug head is screwed in.
