Abstract

Es wird ein Ofen, insbesondere ein Schmelz- oder Warmhalteofen für Metall vorgeschlagen, der ein das flüssige Metallbad (4) aufnehmendes, wärmeiso­ liertes Ofengefäß (1) und mindestens einen in das flüssige Metallbad (4) hineinragenden Tauchheizkörper (7) aufweist. In das flüssige Metallbad (4) ist mindestens eine Tauchwand (8) eingeführt, die den den Tauchheiz­ körper (7) aufnehmenden Bereich von dem übrigen Be­ reich des Schmelzbades abtrennt. Die Abmessungen der Tauchwand (8) ist derart gewählt, daß ein Aus­ tausch des flüssigen Metalls zwischen den Berei­ chen möglich ist.
