wendbarPATENTANSPRÜCHE : 1. Vorrichtung zum Vakuumbehandeln von Stahl beim Giessen, dadurch gekennzeichnet, dass an eine Giesspfanne (1) eine Vakuumkammer (4) gasdicht angehängt ist, die aus zwei mit je einer Saugleitung (14,15) versehenen gasdichten Teilräumen (5,8) mit dazwischen angeordnetem Fuchs (2) besteht, von denen der Hauptteilraum (5) unter dem Boden der Pfanne (1) gasdicht angeordnet ist, und der einen Ausguss (11) mit Stopfenstange (12) aufweisende Nebenteilraum (8) mit einem Deckel (9) abgedichtet ist. PATENT CLAIMS: 1. Device for vacuum treatment of steel during casting, characterized in that a vacuum chamber (4) is attached to a casting ladle (1) in a gas-tight manner, which consists of two gas-tight sub-spaces (5, 8) each provided with a suction line (14, 15) there is a fox (2) arranged in between, of which the main part space (5) is arranged gas-tight under the bottom of the pan (1), and the secondary part space (8) having a spout (11) with stopper rod (12) and a lid (9) is sealed. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der Teilraum (8) eine Belüftungseinrichtung (16) besitzt. 2. Device according to claim 1, characterized in that the subspace (8) has a ventilation device (16). 3. Verfahren zum Betrieb einer Vorrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass nach Evakuieren des Vakuumraumes (4) zunächst der Hauptteilraum (5) und über den Fuchs (7) der Nebenteilraum (8) mit einem ausreichenden Teil des aus der Pfanne (1) kommenden Stahles versehen und darauf der Unterdruck im Nebenteilraum (8) vermindert und aus diesem Raum (8) in Giesspfannen gegossen wird. 3. A method for operating a device according to claims 1 and 2, characterized in that after evacuating the vacuum space (4) first the main part space (5) and via the fox (7) of the secondary part space (8) with a sufficient part of the Ladle (1) provided coming steel and then the negative pressure in the secondary part space (8) is reduced and poured from this space (8) into ladles.
