Description
In der Patentanmeldung C 17251 VIIId/21h ist eine Sicherung der Schraubnippelverbindung bei Kohle oder Graphitelektroden für elektrische Öfen gegen Lockerung beschrieben, welche darin besteht, daß in die Stirnflächen des Gewindenippels und in den Boden der Gewindeschachteln mehrere über die ganze Fläche verteilte Vertiefungen eingearbeitet sind und daß der freie Raum zwischen den Stirnflächen des Gewindenippels und dem Boden der Gewindeschachteln und die eingearbeiteten Vertiefungen mit einem an sich bekannten, von selbst erhärtenden und vor der Verkokung nicht mehr erweichenden Stoff als Sicherungsmaterial ausgefüllt werden, so daß an jedem Ende des Gewindenippels sich eine Scheibe mit mehreren in die Nippelstirnfläche und in den Schachtelboden hineinragenden Zapfen bildet, wodurch eine Verdrehung des Gewindenippels durch die sperrende Wirkung der Zapfen verhindert wird.In the patent application C 17251 VIIId / 21h a securing of the screw nipple connection with carbon or graphite electrodes for electric furnaces against loosening is described, which consists in that in the end faces of the threaded nipple and in the bottom of the threaded boxes several depressions distributed over the entire surface are incorporated and that the free space between the end faces of the threaded nipple and the bottom of the threaded boxes and the incorporated depressions are filled with a known, self-hardening and no longer softening substance before coking as a backup material, so that a washer at each end of the threaded nipple with several pins protruding into the nipple face and into the box bottom, whereby a twisting of the threaded nipple is prevented by the locking effect of the pins.
Nach einem weiteren Merkmal der Hauptpatentanmeldung ist das Gewinde von Nippel und Schachtel durch längs oder schräg verlaufende Nuten mehrfach unterbrochen, wobei die Nuten so eingearbeitet sind, daß beim Zusammenschrauben die Nuten im Nippelgewinde den Nuten im Schachtelgewinde gegenüberstehen oder sie sich kreuzen. Durch diese Nuten, in die ebenfalls das unter hohem Druck von außen hineingepreßte Kittmaterial eindringt, wird eine weitere Sperrung des Nippels gegen Verdrehung erzielt.Another feature of the main patent application is the thread of the nipple and box interrupted several times by longitudinal or inclined grooves, the grooves being incorporated in this way are that when screwing together the grooves in the nipple thread the grooves in the box thread face each other or they cross. Through these grooves, in which the high pressure of If cement material pressed in from the outside penetrates, the nipple is further locked against rotation achieved.
Ein weiteres besonderes Merkmal der Hauptpatentanmeldung besteht darin, daß nach dem Zusammenschrauben der Elektroden das selbsterhärtende Sicherungsmaterial unter hohem Druck von außen in an sich bekannter Weise durch eine dünne Bohrung in die Gewindeschachteln in Höhe des Gewindeschachtelbodens hineingepreßt wird.Another special feature of the main patent application is that after screwing together the electrodes attach the self-hardening fuse material under high pressure from the outside known way through a thin hole in the threaded boxes at the level of the threaded box bottom is pressed into it.
Versuche haben nun ergeben, daß die gleiche sichernde Wirkung erzielt werden kann, wenn das erhärtende Kittmaterial bereits unmittelbar vor dem Zusammenschrauben von Nippel und Elektroden auf den Boden des Nippelloches der unteren Elektrode und auf die obere Stirnfläche des Gewindenippels und in die das Gewinde an mehreren Stellen unterbrechenden Nuten aufgetragen wird. Beim Zusammenschrauben der Elektroden wird das Kittmaterial dann fest zusammengepreßt und wie durch eine Spindelpresse unter hohem Druck gesetzt, wobei der Kitt abgepreßt wird und alle Hohl- und Zwischenräume an den Nippelenden voll ausgefüllt werden. Ein Verdrehen ist nach dem Erhärten der Kittmasse nicht mehr möglich. Das immerhin schwierige Einarbeiten einer dünnen Bohrung in die Gewindeschachteln, das Sicherung der SchraubnippelverbindungExperiments have now shown that the same securing effect can be achieved if the hardening cement material immediately before the nipple and electrodes are screwed together the bottom of the nipple hole of the lower electrode and on the upper face of the threaded nipple and in which the thread is applied at several points interrupting grooves. When screwing together The putty material is then firmly pressed together by the electrodes and as if by a screw press put under high pressure, where the putty is squeezed out and all voids and spaces be completely filled at the nipple ends. There is no twisting after the putty has hardened more is possible. The difficult work of a thin hole in the threaded boxes, that Securing the screw nipple connection

die Schachtelwand etwas schwächen könnte, entfällt damit, so daß keinerlei Gefahr für die Bildung von Rissen mehr besteht. Auch die Anordnung einer Längsbohrung im Nippel ist nicht mehr erforderlich. Erfahrungsgemäß hat sich gezeigt, daß bei kleinen Elektrodenabmessungen die Anbringung nur von Nuten in den Gewindegängen oder nur von Vertiefungen in den Stirnflächen des Nippels und im Schachtelboden genügt. Mit zunehmendem Durchmesser und steigendem Gewicht der Elektroden ist die Vermehrung der Sperrmöglichkeiten zweckmäßig. Aber auch die örtlichen Gegebenheiten an den einzelnen Lichtbogenofen müssen bei der Wahl und der Anzahl der Sperrmöglichkeiten berücksichtigt werden-. Es ist bekannt, daß manche Öfen nahezu erschütterungsfrei laufen, während manche gleicher Größe bei besonders hoher Belastung stark vibrieren. In der Praxis zeigt sich, mit welch geringster Anzahl von Sperrungen eine völlig einwandfreie und feste Elektrodenverbindung erreicht wird.could weaken the box wall somewhat, so there is no danger of the formation of There are more cracks. The arrangement of a longitudinal bore in the nipple is also no longer necessary. Experience has shown that with small electrode dimensions, the attachment of only Grooves in the threads or only of recesses in the end faces of the nipple and in the The bottom of the box is sufficient. With increasing diameter and increasing weight of the electrodes increasing the number of blocking options is expedient. But also the local conditions of the individual Arc furnace must be taken into account when choosing and the number of locking options. It is known that some ovens run almost without vibration, while some run the same Size vibrate strongly under particularly high loads. In practice it turns out with which least Number of locks a completely perfect and solid electrode connection is achieved.
