Abstract
Die Erfindung betrifft einen Drehverschluß für die Auslauföffnung im Boden eines metallurgischen Gefäßes. Um einen solchen Drehverschluß dahingehend weiterzubilden, daß der Zutritt von mit der Schmelze reagierenden Gasen mit möglichst geringem Aufwand verhindert wird, wird erfindungsgemäß vorgeschlagen, daß an den zueinander zugewandten Stirnseiten des Auslaufsteins (1) und des Ausgußteils (2) an dem Auslaufstein (1) eine obere Verschlußplatte (3) bzw. an dem Ausgußteil (2) eine untere Verschlußplatte (4) vorgesehen sind, und wobei die obere Verschlußplatte (3) mit mindestens zwei Durchtrittsöffnungen für mindestens zwei zur Drehachse parallel verlaufende Gießkanäle (7, 8) im Auslaufstein (1) und die untere Verschlußplatte (4) mit mindestens einer Durchtrittsöffnung für mindestens einen Gießkanal (6) im Ausgußteil versehen sind. The invention relates to a rotary closure for the outlet opening in the bottom of a metallurgical vessel. In order to further develop such a rotary closure in such a way that gases reacting with the melt are prevented with as little effort as possible, the invention proposes that the outlet stone (1) and the pouring part (2) on the outlet stone (1) face the mutually facing ends. an upper closing plate (3) or a lower closing plate (4) are provided on the pouring part (2), and the upper closing plate (3) with at least two through openings for at least two pouring channels (7, 8) running parallel to the axis of rotation in the outlet stone (1) and the lower closure plate (4) are provided with at least one passage opening for at least one pouring channel (6) in the pouring part.
