Description
Die Erfindung betrifft eine Vorrichtung zum Vakuumgießen, mit einem Schieber, einem Ausguß und einem Gießstrahlschutzrohr sowie einer den Ausguß und das Gießstrahlschutzrohr gegenein ander luftdicht abschließenden Dichtung.The invention relates to a device for vacuum casting, with a slide, a spout and a pouring tube and one against the spout and the pouring jet protection tube the airtight seal.
Das Vakuumgießen wird zu dem Zweck durchgeführt, einen Reoxidationsschutz zu bilden. Hierdurch wird bewirkt, daß der Sauerstoffzutritt zur Schmelze verhindert wird.The vacuum casting is carried out for the purpose of one Form reoxidation protection. This causes the Oxygen access to the melt is prevented.
Nach dem Stand der Technik wird zum Beispiel in einer Gießpfanne an einen Verteilerausguß ein aus mindestens einer Schieberplatte bestehender Schieber, der eigentliche Ausguß und ein Gießstrahl schutzrohr hintereinander angeordnet. Aufgrund der von vorn herein zwischen dem Verteilerausguß und dem Schieber sowie dem Schieber und dem Ausguß an den Grenzflächen vorgesehenen Mörtelfugen sind die dortigen Anschlußstellen unproblematisch. Da das Gießstrahlschutzrohr jedoch in einen Gießstrahlschutz rohrhalter eingehängt und hiermit an den Ausguß angedrückt werden soll, mangelt es häufig an einer entsprechenden Dichtung beim Übergang des Ausgusses in den Gießstrahlschutzrohrhalter.According to the prior art, for example, in a ladle to a distributor spout from at least one slide plate existing slide, the actual spout and a pouring stream protective tube arranged one behind the other. Because of the front in between the distributor spout and the slide as well as the Slider and the spout provided at the interfaces Mortar joints are no problem at the junctions there. However, since the pouring jet protection tube is in a pouring jet protection tube holder hooked in and hereby pressed onto the spout there is often a lack of an appropriate seal at the transition of the spout into the pouring jet protection tube holder.
Es ist Aufgabe, eine solche Dichtung zu schaffen bzw. die Dichtwirkung an dieser Stelle zu verbessern.It is the task of creating such a seal or the Improve sealing effect at this point.
Die Aufgabe wird bei einem Ausguß dadurch gelöst, daß das Gießstrahlschutzrohr und der Ausguß einteilig gefertigt werden. Diese Ausbildung ist von vornherein hinsichtlich der Dichtigkeit optimal. Weitere vorzugsweise Ausbildungen sind in den Unter ansprüchen 2 und 3 beschrieben.The object is achieved with a spout in that the Pouring protection tube and the spout are made in one piece. This training is a priori in terms of tightness optimal. Further preferred training courses are in the sub claims 2 and 3 described.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in the drawing shown.
Die einzige Figur zeigt einen Verteilerausguß 10, z.B. in einer Verteilerrinne, an den sich ein dreiteiliger aus einer oberen Schieberplatte 11, einer mittleren Schieberplatte 12 und einer unteren Schieberplatte 13 bestehender Schieber anschließt. Unterhalb der unteren Schieberplatte ist die erfindungsgemäße einteilige Ausguß-Gießstrahlschutzrohr-Kombination 14 angeord net, die im oberen Bereich mit einer Blechummantelung 15 versehen ist, welche auch die untere Schieberplatte 13 umfaßt. Aus Gründen der thermischen Expansion sind die nach dem Stand der Technik bekannten Mörtelfugen 16 zwischen der Ausguß-Gieß strahlschutzrohr-Kombination 14 und der unteren Schieberplatte 13 sowie die Mörtelfuge 17 zwischen dem Verteilerausguß 10 und der oberen Schieberplatte 11 vorgesehen. Vorteilhafterweise erspart die einfache Geometrie aufwendige Maßnahmen wie besondere Geometrien z.B. Kugelverbindungen oder Nut-Feder-Systeme und/oder weitere verfahrenstechnische Maßnahmen wie z.B. die Inertisierung durch geeignete gasförmige Medien, die einen Lufteintritt und damit eine Reoxidation des durchfließenden Mediums, z.B. Stahl verhindert.The single figure shows a distributor spout 10 , for example in a distributor channel, to which a three-part slide consisting of an upper slide plate 11 , a middle slide plate 12 and a lower slide plate 13 is connected. Below the lower slide plate, the one-piece pouring pouring tube combination 14 according to the invention is net, which is provided in the upper region with a sheet metal jacket 15 , which also includes the lower slide plate 13 . For reasons of thermal expansion, the mortar joints 16 known from the prior art are provided between the spout-pouring radiation protection tube combination 14 and the lower slide plate 13 and the mortar joint 17 between the distributor spout 10 and the upper slide plate 11 . Advantageously, the simple geometry saves complex measures such as special geometries such as ball joints or tongue and groove systems and / or other procedural measures such as inerting by means of suitable gaseous media, which prevents air from entering and thus reoxidation of the medium flowing through, e.g. steel.
