Description
Deckel mit veränderbaren Elektrodenabständen für elektrische Öfen In der deutschen Patentanmeldung K 40732 IV a; 12 g ist ein aus einem im wesentlichen eine Kreisfläche darstellenden Mittelteil und weiteren abnehmbaren Teilen bestehender Deckel für elektrische Öfen beschrieben. Das Mittelteil kann dabei, wie es schon früher ausgeführt wurde, in Segmente unterteilt sein, die durch Isoliersteine voneinander getrennt sind, wobei je Elektrode zweckmäßig ein. Segment vorgesehen ist.Lid with adjustable electrode spacing for electric ovens In the German patent application K 40732 IV a; 12 g is one of essentially one a central part representing a circular area and further removable parts of existing ones Lids for electric ovens described. The middle part can, as it already does earlier stated, be divided into segments, separated from each other by insulating blocks are separated, each electrode expediently one. Segment is provided.
Die vorliegende Zusatzpatentanmeldung bezieht sich nun auf eine weitere Ausbildung des Deckels mit dem Ziel, eine gewisse Freiheit in der Wahl der Elektrodenabstände zu bekommen.The present additional patent application now relates to another Design of the cover with the aim of a certain freedom in the choice of the electrode spacing to get.
Die Erfindung besteht darin, daß die Segmente des Mittelteils für die kleinsten in Frage kommenden Elektrodenabstände ausgeführt und die beispielsweise dreiteiligen Mittelteile durch Verschieben der Segmente in radialer Richtung unter Vergrößerung der Trennfugen, durch Einsetzen entsprechend verbreiteter Isoliersteine in die Trennfugen und Überbrückung der Trennfugen durch entsprechend verbreiterte Isolierstücke und Verbindungslaschen an größere Elektrodenabstände anpaßbar sind.The invention consists in that the segments of the central part for the smallest possible electrode spacings and the example three-part middle parts by moving the segments in the radial direction below Enlargement of the separating joints by inserting appropriately widened insulating stones in the joints and bridging the joints by widening them accordingly Insulating pieces and connecting tabs can be adapted to larger electrode spacings.
Der Erfindungsgegenstand ist in der Zeichnung unter Weglassung aller im vorliegenden Zusammenhang unwesentlichen Einzelheiten schematisch dargestellt.The subject of the invention is omitted in the drawing in the present context insignificant details are shown schematically.
In der Draufsicht auf den für einen dreiphasigen Ofen gedachten Deckel in Fig. 2 bedeuten 1, 2 und 3 die beispielsweise durch Kreisausschnitte dargestellten Segmente, 4, 5 und 6 die Durchführungsöffnungen für die Elektroden und 7, 8, 9, die in der Stammanmeldung näher beschriebenen, in radialer Richtung vor den Elektroden liegenden, für sich abnehmbaren Teile des Deckels. Die Trennfuge zwischen den zum Deckel zusammengesetzten Segmenten ist mit 10 bezeichnet.In the top view of the lid intended for a three-phase oven In Fig. 2, 1, 2 and 3 denote those shown, for example, by sections of a circle Segments, 4, 5 and 6 the feed-through openings for the electrodes and 7, 8, 9, those described in more detail in the parent application, in the radial direction in front of the electrodes lying, detachable parts of the lid. The parting line between the Segments composed of the cover are denoted by 10.
Fig. 1 stellt einen Längsschnitt durch den Deckel nach der Schnittebene I ... I der Fig. 2 und 3 dar. Fig. 2 und 3 stellen jeweils eine Draufsicht auf den Deckel dar, und zwar Fig. 3 mit verbreiterten Trennfugen 10 und dementsprechend vergrößertem FJlektrodenabstand.Fig. 1 shows a longitudinal section through the cover according to the sectional plane I ... I of Figs. 2 and 3. Figs. 2 and 3 each represent a plan view of the cover, namely Fig. 3 with widened parting lines 10 and accordingly increased electrode spacing.
In Fig. 3 sind die Segmente 1, 2 und 3 von der feststehenden Mittelachse des Ofens um jeweils gleiche oder auch ungleiche Beträge in radialer Richtung weggeschoben. Die ursprüngliche Breite b der Trennfuge 10 vergrößert sich dabei auf den Wert b -I- J b, und der Abstand von Mitte Elektrode, der vorher gleich d war, auf d + d d. Die Werte b -i- d b brauchen dabei nicht unter sich gleich zu sein. Das gleiche gilt auch von den Werten d -!- J d. In Fig. 4 ist ein Schnitt durch die Trennfuge 10 der Fig. 2 dargestellt. 1 und 2 sind wieder die Segmente. Zwischen ihnen liegen Isoliersteine 13. Nach oben ist die Trennfuge 10 durch Isolierstücke 11 und Verbindungslaschen 12 abgeschlossen. Durch die Teile 11 und 12 werden gleichzeitig die Segmente in der richtigen Lage zueinander festgehalten.In Fig. 3, the segments 1, 2 and 3 are pushed away from the fixed central axis of the furnace by the same or unequal amounts in the radial direction. The original width b of the joint 10 increases to the value b -I- J b, and the distance from the center of the electrode, which was previously equal to d , to d + d d. The values b -idb do not have to be the same among themselves. The same also applies to the values d -! - J d. In FIG. 4, a section through the parting line 10 of FIG. 2 is shown. 1 and 2 are the segments again. There are insulating blocks 13 between them. The separating line 10 is closed off at the top by insulating pieces 11 and connecting straps 12. The segments 11 and 12 simultaneously hold the segments in the correct position relative to one another.
Fig. 5 zeigt den Querschnitt durch die Trennfuge 10 der Fig. 3. Die Trennfuge 10 ist hier, wie oben dargelegt, verbreitert, und die Isoliersteine 13, die Isolierstücke 11 sowie die Verbindungslaschen 12 sind dieser Verbreiterung angepaßt.FIG. 5 shows the cross section through the parting line 10 of FIG. 3. The parting line 10 is widened here, as explained above, and the insulating stones 13, the insulating pieces 11 and the connecting tabs 12 are adapted to this widening.
Die bei der Verbreiterung der Trennfuge 10 sich einstellende Abweichung der Umfangslinie des Deckels von der beispielsweise idealen Kreisform ist für die praktischen Belange unwesentlich.The deviation of the circumferential line of the cover from the ideal circular shape, for example, which occurs when the parting line 10 is widened, is insignificant for practical purposes.
Der Erfindungsgegenstand bringt den großen Vorteil, daß auch für Ofenwannen unterschiedlichen Durchmessers die Deckel aus ein und denselben Bauteilen zusammengesetzt werden können. Damit ist eine Vereinfachung der Lagerhaltung und eine Erleichterung der Reparaturarbeiten gegeben.The subject of the invention has the great advantage that also for furnace pans With different diameters, the lids are composed of one and the same components can be. This simplifies storage and makes it easier given the repair work.
Der Vorschlag kann auch Bedeutung gewinnen, für Fälle, beispielsweise beim Bau von Versuchsöfen für metallurgische Zwecke, in denen nicht von vornherein Klarheit über den zweckmäßigsten Elektrodenabstand besteht.The suggestion can also gain relevance for cases, for example when building experimental furnaces for metallurgical purposes, in which not a priori There is clarity about the most appropriate electrode spacing.
