PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Elektroden mit metallischem, gekühltem Kopfe und bezweckt, eine leicht lösbare Verbindung zwischen der Elektrode und dem Elektrodenkopfe zu schaffen, bei der zugleich die schädlichen Wirkungen von Funkenbildungen zwischen der Elektrode und dem Elektrodenkopfe mit Sicherheit beseitigt sind.The invention relates to electrodes with a metallic, cooled head and aims to create an easily detachable connection between the electrode and the electrode head, in which at the same time the harmful Effects of spark formation between the electrode and the electrode head with certainty are eliminated.
Auf der Zeichnung ist ein für elektrischeOn the drawing is one for electrical
ίο Öfen bestimmtes Ausführungsbeispiel der Erfindung veranschaulicht, und zwar ist ein Längsschnitt durch den oberen Teil der Elektrode, des Elektrodenkopfes und des zugehörigen Lagers dargestellt.ίο ovens specific embodiment of the invention illustrated, namely a longitudinal section through the upper part of the electrode, of the electrode head and the associated bearing.
Mit der aus Kohle bestehenden Elektrode A ist der durch Wasser gekühlte metallische Kopf B, welcher in der aus der Zeichnung ersichtlichen Weise ausgebildet ist, mittels eines ebenfalls durch das Kühlwasser bespülten Gewindezapfens b1 verbunden, und zwar ragt der Gewindezapfen b1 mit Spielraum in einen mit entsprechendem Gewinde versehenen Hohlraum der Kohle hinein. Der Spielraum ist mit einem leicht schmelzenden Metalle C, dessen Schmelzpunkt zweckmäßig unter 350° liegt, z. B. mit Woodschem Metalle, ausgefüllt. Der Elektrodenkopf B ist an einem Arme D gelagert, der an einer — nicht dargestellten — Säule auf und nieder bewegt werden kann.With the group consisting of carbon electrode A is cooled by water metallic head B, which is formed in the manner shown in the drawing way, by means of a bespülten also by the cooling water threaded stem b 1 is connected, and that extends the threaded stem b 1 with clearance in a with a correspondingly threaded cavity of the coal into it. The scope is with an easily melting metal C, the melting point of which is suitably below 350 °, z. B. with Woodschem metals filled. The electrode head B is mounted on an arm D which can be moved up and down on a column (not shown).
Ist die Berührung zwischen der Kohle und der Metallfüllung C oder zwischen dem Zapfen b1 und der Metallfüllung C an irgendeiner Stelle keine vollständige, so daß beim Durchgange des elektrischen Stromes Funken entstehen, so schmilzt infolge der hierdurch entstehenden Hitze das der Stelle benachbarte Metall sofort und füllt die Lücke aus. Die Funkenbildung hört somit sofort wieder auf, ehe eine Beschädigung des Gewindes eintreten kann. Soll die Verbindung zwischen der Kohle und dem Kopfe B gelöst werden, so wird während des Stromdurchganges die Kühlung abgestellt. Infolgedessen tritt eine so hohe Erwärmung ein, daß das Metall C schmilzt. Die Kohle, die vermöge der aus der Figur ersichtlichen Ausbildung des Zapfens auch nach dem Schmelzen der Metallfüllung von dem Zapfen getragen wird, kann nunmehr leicht abgeschraubt werden. Das Metall C sammelt sich auf dem Grunde des Hohlraumes der Kohle und kann ohne Verlust wieder benutzt werden. If the contact between the carbon and the metal filling C or between the pin b 1 and the metal filling C is not complete at any point, so that sparks are produced when the electric current passes, the metal adjacent to the point melts immediately and as a result of the resulting heat fills the gap. The sparking stops immediately before the thread can be damaged. If the connection between the carbon and the head B is to be released, the cooling is switched off during the passage of the current. As a result, the heating is so high that the metal C melts. The coal, which is carried by the pin even after the metal filling has melted due to the configuration of the pin which can be seen in the figure, can now be easily unscrewed. The metal C collects at the bottom of the cavity of the coal and can be used again without loss.
