Abstract
(DE)
Die Vorrichtung hat ein übliches Startrohr am Einlauf der Ausgußöffnung (5) eines Verteilergefäßes und zeichnet sich durch einen separaten Startkörper aus, der lose besagtem Startrohr zugeordnet ist und bei Erreichen einer gewünschten Füllstandshöhe (H) der Schmelze (6) aufschwimmt. Dadurch wird die Vorrichtung mit einfachen Mitteln wirkungsmäßig verbessert und automatisch ein zeitgerechter Abfluß schlackenfreier Schmelze am Startrohr (12) ermöglicht.
(EN)
The device has a conventional starting pipe at the inlet of the discharge orifice (5) of a distributor vessel and a separate starting body which is loosely associated with the starting pipe and which floats when the melt (6) reaches a desired height (H). The device is therefore improved using simple means and permits automatic, correctly timed flow of slag-free melt from the starting pipe (12).
(FR)
Un dispositif comprend un tuyau usuel de départ à l'entrée d'un orifice de décharge (5) d'un récipient distributeur et un corps séparé de départ, associé de manière lâche audit tuyau de départ, qui flotte sur la fonte (6) lorsque celle-ci atteint la hauteur (H) voulue de remplissage. Le fonctionnement du dispositif est ainsi amélioré avec des moyens simples et permet de manière automatique à la fonte exempte de scories de s'écouler à temps par le tuyau de départ (12).
