Description

Elektroschmelzofen .Die Erfindung betrifft einen Elektroschmelzofen, bei dem zum Abheben des Deckels und der Elektroden ein besonderes Hubwerk vorgesehen ist.Electric melting furnace. The invention relates to an electric melting furnace, in which a special lifting mechanism is provided for lifting off the cover and the electrodes is.

Nach den bekannten Ausführungen wird dieses Hubwerk entweder vierfahrbar angeordnet, oder es befindet sich fest an der Ofenwiege. In beiden Fällen macht das Hubwerk für den Deckel und die Elektroden die Kippbewegungen des Ofens mit.According to the known designs, this hoist is either four-wheeled or it is fixed to the oven cradle. In both cases it does the lifting mechanism for the lid and the electrodes also tilt the furnace.

Beim Beschicken des Ofengefäßes wird in dem oben an erster Stelle genannten Falle der Deckel mit Elektroden abgehoben und durch das Verfahren des Hubwerks aus denn Bereich des Ofens herausgebracht.When loading the furnace vessel, the above is the first thing to do mentioned case, the cover with electrodes is lifted off and by the method of Lifting gear brought out of the furnace area.

Bei der an zweiter Stelle genannten Konstruktion wird zwecks Beschickung des Ofengefäßes dieses selbst nach Abheben des Dekkels mit den Elektroden von der Wiege auf eine feste Fahrbahn abgefahren.In the case of the construction mentioned in the second position, for the purpose of loading of the furnace vessel this itself after lifting the lid with the electrodes from the Cradle driven on a solid road.

Beide Ausführungen haben den Nachteil, daß beim Überfahren der einander zugekehrten Schienenstöße auf der Ofenwiege und auf der festen Plattform starke Stöße entstehen, die sich nachteilig auf das Kipp- bzw. Hebewerk auswirken.Both versions have the disadvantage that when driving over each other facing rail joints on the furnace cradle and on the fixed platform strong Shocks occur that have a detrimental effect on the tilting or lifting mechanism.

Diesem Mangel hilft die Erfindung in einfachster Weise ab. Sie kennzeichnet sich durch die Vereinigung eines mit Deckel und Elektroden kippbaren Schmelzgefäßes, das mit dem Kippwerk vierfahrbar ist, mit einem ortsfesten Hubwerk für Deckel und Elektrodenbrücke.The invention remedies this deficiency in the simplest possible way. She identifies by combining a melting vessel with lid and electrodes that can be tilted, which is four-wheeled with the tilting mechanism, with a fixed lifting mechanism for cover and Electrode bridge.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt Abb. i den Elektrodenschmelzofen in der Vorderansicht, zu der Abb. 2 eine Seitenansicht wiedergibt. Das Schmelzgefäß des Ofens ist mit i und der bierzugehörige Deckel mit 2 bezeichnet. Letzterer hängt vermittels der angedeuteten Ketten 3 an der Brücke .4, die im Betriebszustand des Ofens mit ihren Füßen auf konsolartigen Vorsprüngen 6 des Schmelzgefäßes i aufsitzen. Wie aus der Zeichnung erkenntlich, liegen die obengenannten Füße 5 in dem Bereich der Bewegungsbahnen der Mitnehmer 8,. die auf Rollen geführt und in den Säulen 9 heb- und senkbar sind. Der Antrieb der Mitnehmer erfolgt mit Hilfe der Zugorgane durch die aus dem Motor i i und Trommeln 12 gebildeten Winde, die ortsfest aufgestellt ist.An embodiment of the invention is shown in the drawing, namely Fig. i shows the electrode melting furnace in a front view, to which Fig. Figure 2 shows a side view. The furnace's melting vessel is marked with i and the one belonging to it Cover labeled 2. The latter is attached by means of the indicated chains 3 the bridge .4, which is in the operating state of the furnace with its feet on console-like Sit on the projections 6 of the melting vessel i. As can be seen from the drawing, the above-mentioned feet 5 lie in the area of the movement paths of the drivers 8th,. which are guided on rollers and can be raised and lowered in the columns 9. The drive the driver takes place with the help of the pulling elements through the motor i i and drums 12 formed winch, which is set up stationary.

Das im wesentlichen aus den Wiegen 13, den Stützrollen, dem auf die Wiegen 13 arbeitenden Getriebe 16 bestehende Kippwerk für .das Schmelzgefäß ist auf einem Fahrgestell 15 untergebracht, dessen Fahrantrieb durch 17 angedeutet ist.That essentially consists of the cradles 13, the support rollers, which on the Weighing 13 working gear 16 existing tilting mechanism for. The melting vessel is housed on a chassis 15, the drive mechanism is indicated by 17.

Bei Vornahme der Beschickung des Schmelzgefäßes wird mit Hilfe der Winde i i, 17 die Brücke q. mit dem Deckel angehoben, so daß das Kippwerk mit dem Schmelzgefäß aus dem Bereich des Deckels herausgefahren und beschickt werden kann.When the melting vessel is being charged, the bridge q is opened using the winch ii, 1 7. with the lid raised so that the tilting mechanism with the melting vessel can be moved out of the area of the lid and loaded.
