Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Wärmebehandlung metallischer Werkstücke, bei dem durch einen von einem Drehstrommotor angetriebenen Ventilator ein Kühlgasstrom in einem Vakuumofen zum Abschrecken der Werkstücke erzeugt wird. Um die Wärmebehandlung metallischer Werkstücke dahingehend weiterzubilden, daß sich auf einfache und kostengünstige Weise eine verbesserte Abschreckung erzielen läßt, wird erfindungsgemäß vorgeschlagen, daß der Drehstrommotor für eine geringere Versorgungsspannung ausgelegte erste Drehstromwicklungen und für eine höhere Versorgungsspannung ausgelegte zweite Drehstromwicklungen aufweist, wobei der Drehstrommotor bis zum Erreichen eines hinsichtlich seiner Motorleistung bestimmten Mindestdrucks in dem Vakuumofen unter Nutzung der ersten Drehstromwicklungen und bei Erreichen oder Überschreiten des hinsichtlich seiner Motorleistung bestimmten Mindestdrucks in dem Vakuumofen unter Nutzung der zweiten Drehstromwicklungen betrieben wird.
