Abstract

Die feuerfeste Stator/Rotor-Einheit für einen Verschluss am Aus­ guss eines Metallschmelze enthaltenden Gefässes (11) besteht aus einem in der Gefässwandung (14) befestigten Stator (15) und einem in diesem von der Gefässboden-Unterseite (11′) aus dreh­ baren, zum Oeffnen resp. Schliessen des Verschlusses dienenden Rotor (16). Die in das Gefäss hineinragende Einheit hat darin verlaufende querliegende Oeffnungen (17,18) und von diesen aus­ gehend eine aus dem gefäss führende Ausgussöffnung (19′). Zwi­ schen dem Rotor (16) und dem Stator (15) ist in dem gesamten innerhalb des Gefässes liegenden Bereich eine die querliegenden Oeffnungen (17,18) umgebende abdichtende zylindrische Fläche (20), während in dem in der Gefässwandung (14) liegenden Bereich ein die unterschiedlichen Wärmeasudehnungen von Stator und Rotor aufnehmendes Spiel (22) zum Verhindern eines Klemmens der Ein­ heit vorgesehen. Damit ist ein sehr einfaches, platzsparendes und mit hoher Betriebssicherheit funtionierendes Verschluss­ system geschaffen. The fireproof stator / rotor unit for a closure at the end Casting a vessel (11) containing molten metal consists of a stator (15) fastened in the vessel wall (14) and one in this from the bottom of the vessel bottom (11 ') from cash, to open resp. Closing the clasp serving Rotor (16). The unit protruding into the vessel has in it running transverse openings (17, 18) and from these going a pouring opening leading from the vessel (19 '). Between rule the rotor (16) and the stator (15) is in the whole the area lying inside the vessel is the transverse one Sealing cylindrical surface surrounding openings (17, 18) (20), while in the area in the vessel wall (14) the different thermal expansion of stator and rotor receiving game (22) to prevent jamming of the one provided. This is a very simple, space-saving and the closure works with a high level of operational safety system created.
