PATENTAMT.PATENT OFFICE.
Den Gegenstand dieser Erfindung bilden Neuerungen, durch die der ununterbrochene Betrieb des elektrischen Ofens und die Trennung des Lichtbogens und des zu schmelzenden Stoffes durch eine feuerbeständige Wand erhalten bleibt und das Schmelzen und Ausfliefsen des geschmolzenen Stoffes in einen geschlossenen Ofen so verwirklicht wird, dafs bis zum Ausfiiefsen der ganze Theil des Rohres, der in den Ofen hineinreicht, erwärmt und der geschmolzene Stoff der Berührung mit der äufseren Luft entzogen wird.The subject of this invention are innovations through which the uninterrupted Operation of the electric furnace and the separation of the arc and that to be melted The substance is retained by a fire-resistant wall and prevents it from melting and flowing out of the molten substance is carried out in a closed furnace in such a way that Until it flows out, the whole part of the pipe which extends into the furnace is heated and the molten substance is withdrawn from contact with the outside air.
Bei dieser neuen Construction wird der Ofen aus zwei Haupttheilen gebildet: einem unteren, a, und einem oberen, b. Die Verbindung zwischen diesen beiden Theilen wird durch einen Kitt gebildet.In this new construction the furnace is made up of two main parts: a lower, a, and an upper, b. The connection between these two parts is formed by a putty.
Der untere Theil ist in Form eines Sammeltrichters e in einem Theil der Ofensohle ausgehöhlt oder reicht über die ganze Ofensohle hinweg. Dieser Sammeltrichter ist durch Gleiten, Rollen oder Drehen derart von seinem Platz beweglich, dafs er durch einen anderen ersetzt werden kann. Es könnte auch der obere Theil so beweglich sein, dafs er von einem Sammeltrichter auf den anderen gebracht werden könnte.The lower part is hollowed out in the form of a collecting funnel e in one part of the furnace base or extends over the whole furnace base. This collecting funnel can be moved from its place by sliding, rolling or rotating in such a way that it can be replaced by another. The upper part could also be so mobile that it could be moved from one collecting funnel to the other.
Der obere Theil des Ofens, der das eigentliche Ofengewölbe bildet, nimmt die Muffelrohre und die beweglichen Elektroden auf. Das Muffelrohr ist genügend geneigt, kann ein einfaches Rohr sein und besitzt an seinem unteren Theil eine Oeffnung O, durch die der geschmolzene Stoff in den Sammeltrichter fliefst; so wird es durch das Rohr d in Fig. 1 veranschaulicht. Es kann auch doppelt und in V-Form gestaltet zur Verwendung kommen mit einer Oeffnung am Scheitel des V, die zum Ausflufs der geschmolzenen Masse dient; so veranschaulichen es die Rohre df1 of2 in Fig. 2.The upper part of the furnace, which forms the actual furnace vault, houses the muffle tubes and the movable electrodes. The muffle tube is sufficiently inclined, can be a simple tube, and has in its lower part an opening O through which the molten substance flows into the collecting funnel; so it is illustrated by tube d in FIG. It can also be used in a double V-shape with an opening at the apex of the V, which is used for the outflow of the molten mass; this is illustrated by the tubes df 1 of 2 in FIG. 2.
Elektroden cc , in genügender ZahlElectrodes cc , in sufficient number
und verschieden angeordnet, erhitzen die ganze Masse, die durch die Rohre d oder d1 d2 in den Ofen vordringt.and arranged differently, heat the whole mass that penetrates through the tubes d or d 1 d 2 into the furnace.
Aufserdem sind Elektroden C1C1 besonders angeordnet, damit der Lichtbogen, der zwischen ihnen spielt, nahe der Ausflufsöffnung der geschmolzenen Masse überspringt, damit dieser Ausflufs mit Leichtigkeit bewirkt wird.In addition, electrodes C 1 C 1 are specially arranged so that the arc that plays between them jumps near the outflow opening of the molten mass, so that this outflow is effected with ease.
