Description

Elektroden für Salzbad-Härteöfen. Es ist bekannt, in elektrisch geheizten Salzbad-Härteöfen die Stromverteilung in dem flüssigen Salzbad dadurch gleichmäßig zu gestalten, daß man die senkrecht in das Bad eintauchenden Elektroden von der Stromanschlußstelle aus breiter werden läßt.Electrodes for salt bath hardening furnaces. It is known in electrically heated Salt bath hardening ovens distribute the current evenly in the liquid salt bath to make that one of the electrodes immersed vertically in the bath of the Power connection point can be made wider.

Nach der vorliegenden Erfindung ist eine solche Verbreiterung nicht nötig, so daß schon im oberen Teil des Bades die volle Breite des Behälters zum Eintauchen der zu härtenden Gegenstände ausgenutzt werden kann. Danach wird bei beliebiger, zweckmäßig konstanter Breite der Elektroden ihr gegenseitiger Abstand von der Stromanschlußstelle aus nach ihrem Ende hin verringert. Ein derartiger Härteofen ist schematisch in der Zeichnung dargestellt, in der Abb. z einen Schnitt durch den Ofen und Abb. -" die Seitenansicht einer Elektrode zeigt.According to the present invention, there is no such widening necessary, so that the full width of the tank is already in the upper part of the bath Immersion of the objects to be hardened can be exploited. After that, at arbitrary, expediently constant width of the electrodes their mutual distance reduced from the power connection point towards its end. Such a hardening furnace is shown schematically in the drawing, in Fig. Z a section through the furnace and Fig. - "shows the side view of an electrode.

Ob die Stromanschlußstelle am oberen oder unteren Ende oder in der Mitte der Elektroden liegt, ist für die Erfindung belanglos.Whether the power connection point at the upper or lower end or in the The middle of the electrodes is irrelevant for the invention.
