Abstract
(DE)
Vorrichtung zum zeitweiligen Abdichten einer Abstichöffnung (12), die einen ersten Innendurchmesser (d3) aufweist und im Boden (10, 11) eines metallurgischen Ofens (100) vorgesehen ist, und zum Verfüllen der Abstichöffnung (12) mit einer rieselfähigen feuerfesten Masse VM, mit einem Dicht- und Verfüllrohr (31) mit einer ersten Länge I1 und einer unteren Öffnung (31u) und einer oberen Öffnung (31o), einem ersten Behälter (32) für Verfüllmasse VM, einer Öffnungs- und Schließvorrichtung (33), und einem Hubwerk (40), bei der das Dicht- und Verfüllrohr (31), der erste Behälter (32) und die Öffnungs- und Schließvorrichtung (33) an dem Hubwerk (40) derart befestigt sind, dass der erste Behälter (32) unter Zwischenschaltung der Öffnungs- und Schließvorrichtung (33) mit der oberen Öffnung (31o) des Dicht- und Verfüllrohrs (31) so verbunden ist, dass die Verbindung durch die Öffnungs- und Schließvorrichtung unter Steuerung durch eine Steuervorrichtung offenbar und verschließbar ist, das Dicht- und Verfüllrohr (31) an seiner Unterseite einen Außendurchmesser d2 aufweist, der größer als der erste Innendurchmesser d3 ist, und das Hubwerk zum Ermöglichen eines Verfahrens des Dicht- und Verfüllrohrs (31) in Längsrichtung desselben mit einer Geschwindigkeit > 200 mm/s ausgebildet ist.
(EN)
Device for temporarily sealing a tap hole (12) which has a first internal diameter (d3) and is provided in the bottom (10, 11) of a metallurgical furnace (100), and for filling the tap hole (12) with a free-flowing fire-resistant compound VM, having a sealing and filling pipe (31) with a first length I1 and a bottom opening (31u) and a top opening (31o), a first container (32) for filling compound VM, an opening and closing device (33), and a lifting mechanism (40), in which device the sealing and filling pipe (31), the first container (32) and the opening and closing device (33) are fixed to the lifting mechanism (14) in such a way that the first container (32), with the interposition of the opening and closing device (33), is connected to the top opening (31o) of the sealing and filling pipe (31) such that the connection can be opened and closed by the opening and closing device under the control of a control device, the sealing and filling pipe (31) has on its underside an external diameter d2 which is greater than the first internal diameter, and the lifting mechanism is designed to permit the sealing and filling pipe (31) to be moved in the longitudinal direction of the same at a speed > 200 mm/s.

L'invention concerne un dispositif permettant d'étanchéifier temporairement un trou de percée (12) qui présente un premier diamètre intérieur (d3) et qui se trouve dans le fond (10, 11) d'un four métallurgique (100), ainsi que de remplir le trou de percée (12) avec une matière réfractaire coulante VM, ledit dispositif comportant un tube d'étanchéité et de remplissage (31) présentant une première longueur I1 et une ouverture inférieure (31u) et une ouverture supérieure (31o), un premier réservoir (32) pour la matière de remplissage VM, un dispositif d'ouverture et de fermeture (33) et un mécanisme de levage (40), le tube d'étanchéité et de remplissage (31), le premier réservoir (32) et le dispositif d'ouverture et de fermeture (33) étant fixés au mécanisme de levage (40) de telle manière que du fait de l'interposition du dispositif d'ouverture et de fermeture (33), le premier réservoir (32) est relié à l'ouverture supérieure (31o) du tube d'étanchéité et de remplissage (31) de telle manière que cette liaison peut être ouverte ou fermée par le dispositif d'ouverture et de fermeture commandé par un dispositif de commande. Le tube d'étanchéité et de remplissage (31) présente sur son côté inférieur un diamètre extérieur d2 qui est supérieur au premier diamètre intérieur d3 et le mécanisme de levage est configuré pour permettre un déplacement du tube d'étanchéité et de remplissage (31) dans sa direction longitudinale à une vitesse supérieure à 200 mm/s.
