Vorrichtung sun Gießen von Metallen, insbesondere von Stahl, in KokillenDevice sun casting of metals, especially steel, in molds
BLe Erfindung betrifft eine "Vorrichtung z\ len, insbesondere von Stahl, in Kokillen.The invention relates to a "device for cells, in particular of steel, in molds.
Ss ist bekannt, daß bei unberuhigt erstarrenden Stühlen eia guter Kochvurgang während der Erstattung zu einer r»inem. blasenfreien Bandzone der Blöcke führt· Zur Brreiehnag eia·· besseren Kochvorganges wird neuerdings der flüssige Stahletrahl während des Gießens mittels einer auf der Kokille Hegernten oder unterhalb des Pfannenausgusses angebrachten Vorrichtung mit gasförmigem Sauerstoff angeblasen. Biese Vorrichtung besteht normalerweise aus einer den Gießstrahl umgebenden Hagle it ung mit mehreren Offnungen· Bei dieser Behanefluagsweise muß allerdings zur Erzielung der gewünschten Sauerstoffanreicherung des Strahles mit größeren Verlusten an ungenützt abgeleitetem Sauerstoff gerechnet werden. Zudem sind die Siegle itungen aus Kupfer teuer in Anschaffungspreis und erfordern einen kostspieligen Unterhalt bei geringer Lebensdauer, nachteilig wirken sich besonders die Umstände aus, daß die öffnungen sehr rasch durch flüssige Metallspritzer verstopft werden, daß sich der Ring in der Hitze, der er ausgesetzt ist,It is known that in the case of unrestrained stools eia good cooking process during the reimbursement to a clean one. Bubble-free belt zone of the blocks leads to · The liquid steel jet has recently been used to improve the cooking process during the casting by means of a Hegernten on the mold or under the ladle spout attached device blown with gaseous oxygen. This device usually consists of a hail duct that surrounds the pouring stream and has several openings However, in order to achieve the desired oxygen enrichment of the jet, greater losses of unused derived oxygen must be expected. In addition, the copper sealing lines are expensive to purchase and require expensive maintenance with a short service life, disadvantageous in particular are the fact that the openings are very quickly clogged by liquid metal splashes, that the ring in the heat to which it is exposed,
schnell verbiegt und daß die Schweißstellen nur kurze Zeit halten.bends quickly and that the welds only last a short time.
Der Erfindung liegt nun die Aufgabe zugrunde, eine wirkungsvollere und wirtschaftlichere Sauerstoffbehandlung des Gießstrahles zu gewährleisten«The invention is now based on the object of a more effective and more economical oxygen treatment of the pouring stream to ensure"
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ausgußstein der KoMlIe mit einer seitlichen Bohrung zur Einführung einer Sauer stoff leitung versehen i^t. Die Bohrung zur Sauers to ff zuführung kann senkrecht zur Ausflußrichtung des Ausguß- ; steins angeordnet sein; indessen kann die Bohrleitung zur Sau-According to the invention, this object is achieved in that the pouring stone the KoMlIe with a lateral hole for introduction provided with an oxygen line i ^ t. The hole to the Sauers to ff supply can be perpendicular to the outflow direction of the spout; stone be arranged; meanwhile, the drilling pipe to the sowing

Das Anblasen des Strahles, wührend dieser sich etwa auf der Hälfte der Weglänge des Ausgußsteines befindet, hat den Vorteil, daß das in einen seitlichund nach oben abgeschlossenen Baum einströmende Gas nicht so leicht ausweichen kann wie bei demBlowing on the beam while it is about on the Half of the path of the pouring stone is located, has the advantage that this is in a tree that is closed off at the side and at the top inflowing gas cannot escape as easily as with the

Pig. 3 einen Ausgußformatein mit tangentialer Zufuhrbohrung.Pig. 3 a spout format with a tangential feed bore.
Zum Anblasen des gebündelten Metallstrahles im Innern des Ausgußsteines 1 wird dieser, wie dies aus den Figuren 1 bis 3 ersichtlich ist, mit einer seitlichen Zufuhtoöffnung versehen. Die Gaszufuhr erfolgt über eine mit einem Regolventil 8 ausgestattete Bohrleitung 7· Der hermetisch in den Formstein 1 eingelassene Verbinduhgsstutzen 5 wird über eine Kupplung 6 mit der Bohrleitung 7 verbunden. Die Bohrleitung 7 kann auch direkt lose in die etwas weitere Bohrung 9 im Gießrohr 1 eingeführt werden. (Fig. 3)· Each Fig. 2 ist die Bohrung so geführt, daß der Gasstrahl senkrecht auf den Metallstrom auftrifft^ nach Fig. 3 erfolgt die Berührung tangential. Bei entsprechender Bohrung kann der Gasstrahl auch schräg abwärts gerichtet sein. Wichtig ist in allen Fällen, daß das Anblasen des Metalls im Innern des Gießrohres selbst erfolgt, weil nur auf diese Weise und im Gegensatz zu den bis dahin vorgeschlagenen Anblas verfahr en eine optimale, gut ateuerbaire und weitgehend verlustfreie Reaktion mit dem Metall erfolgen kann.For blowing the bundled metal jet inside the pouring stone 1, as can be seen from FIGS. 1 to 3, this is provided with a lateral feed opening. The gas is supplied via a valve equipped with a control valve 8 Drilling line 7 · The connection stub 5, which is hermetically embedded in the molded block 1, is connected to it via a coupling 6 the drilling line 7 connected. The drilling line 7 can also be loosely inserted directly into the somewhat wider bore 9 in the pouring pipe 1 will. (Fig. 3) · Each Fig. 2 the hole is guided so that the gas jet strikes the metal stream perpendicularly ^ according to Fig. 3, the contact is tangential. With the appropriate drilling, the gas jet can also be directed obliquely downwards be. It is important in all cases that the metal is blown inside the pouring pipe itself, because only on This way, and in contrast to the previously proposed blowing methods, an optimal, well affordable and largely Loss-free reaction with the metal can take place.
Die erfindungsgemäße Vorrichtung erlaubt außerdem eine Suspension von Feststoffen mit einzublasen. Auf diese Weise körinen die bis dahin von Hand getätigten Zuschläge von pulver- oder kornförmigen Zusatzstoffen weit vorteilhafter in das flüssige Metall eingebracht werden.The device according to the invention also allows a suspension of solids to be injected at the same time. In this way körinen The additions of powder or granular additives, which were previously made by hand, are much more advantageous to the liquid Metal can be introduced.
