Description
Elektroden für Salzbad-Härteöfen. Bei den elektrisch geheizten Härteöfen mit einem durch Stromwärme verflüssigten Salzbad hat man Elektroden von rechteckiger Gestalt benutzt, die senkrecht in das Schmelzbad eintauchten. Dabei zeigte sich eine ungleichmäßige Stromverteilung, so daß die Erhitzung des Bades in der Nähe der Stromzuführungsstellen größer war als zwischen den Elektrodenenden. Es ist daher vorgeschlagen worden, die Fläche der Elektroden von den Stromzuführungsstellen aus zunehmen zu lassen, so daß eine gleichmäßige Stromverteilung erzielt wird.Electrodes for salt bath hardening furnaces. With the electrically heated hardening ovens with a salt bath liquefied by the heat of electricity one has electrodes of rectangular shape Shape used that plunged vertically into the weld pool. It showed an uneven current distribution, so that the heating of the bath in the vicinity the power supply points was larger than between the electrode ends. It is therefore has been proposed, the area of the electrodes from the power supply points to be allowed to increase, so that a uniform current distribution is achieved.
Nach der Erfindung wird die gewünschte Wirkung auf andere Weise erreicht, indem nämlich die Elektroden zunächst in gleichmäßiger Breite senkrecht nach unten in das Schmelzbad hineingeführt, dann aber nach der einander zugekehrten Seite nach oben umgebogen werden.According to the invention, the desired effect is achieved in another way, namely by first placing the electrodes at a uniform width vertically downwards led into the weld pool, but then to the side facing each other be bent over at the top.
Der umgebogene Lappen der Elektroden wird dann entweder gemäß Abb. x und 2 nach dem oberen Ende zu verschmälert oder gemäß Abb. 3 und 4 bei ungeänderter Breite mit nach obenzu vergrößertem gegenseitigen Abstand ausgeführt. Die beiden Ausführungsarten können auch vereinigt werden.The bent flap of the electrodes is then either inserted as shown in Fig. x and 2 narrowed towards the upper end or as shown in Fig. 3 and 4 with unchanged Width carried out with upward to increased mutual distance. The two Types of execution can also be combined.
