Abstract

Eine Induktionsspule für Induktionstiegelöfen ist aus mehre­ ren getrennt voneinander beaufschlagbaren Spulenabschnitten (2,3,6,7,8) aufgebaut, die koaxial mit Abstand übereinander angeordnet sind. In dem Zwischenraum von jeweils zwei Spulen­ abschnitten (2,3,6,7,8) befindet sich jeweils mindestens eine Kühlspule (4,9,10) aus unmagnetischem Stahl. Die Höhe der Kühlspule (4,9,10) bzw. der Kühlspulen liegt zwischen 100 und 250 mm.
