Abstract

Eine Vorrichtung zum Elektroschlacke-Umschmelzen von Metallen, umfasst einen Vorwärmofen (1) zum Vorwärmen einer selbstverzehrende Abschmelzelektrode (13) vor ihrer Zuführung an ein Schlackenbad und ist erfindungsgemäß dadurch gekennzeichnet, dass der Vorwärmofen (1) mit wenigstens einem Brenner (9, 10) ausgerüstet ist, mittels dem die Vorwärmung der Abschmelzelektrode (13) durch Verbrennung eines Brennstoffs mit einem Oxidator erfolgt. Bei der Vorwärmung wird zumindest die Spitze (14) der Abschmelzelektrode (13) in den Vorwärmofen (1) eingeführt und durch Kontaktieren mit einem miteinander reagierenden Brennstoff-Oxidator-Gemisches beheizt. Bevorzugt wird bei der Beheizung dabei ein Flammen-Zyklon erzeugt, der eine gleichmäßige Erwärmung der Spitze (14) der ermöglicht.
