Abstract

Bei einem Schmelz- und Warmhalteofen für flüssige Metalle ist eine Umwälzvorrichtung (8, 10) zur Umwälzung der sich über der Schmelze (5) im Heizraum (3) befindlichen Heißluft vorgesehen. With a melting and holding furnace for liquid Metals is a circulation device (8, 10) for circulation the one above the melt (5) in the boiler room (3) Hot air provided.

Damit wird eine stabile Luftschichtung über der Schmelze (5) verhindert und an der Oberkante der Wanne (1) kann sich keine harte Kruste (7) aus gesintertem Metall bilden, die sonst mit erheblichem Zeitaufwand entfernt wer­ den müsste. Damit wird eine wesentliche Verbesserung und Verbilligung des Warmhalteprozesses erzielt. This creates a stable stratification of air above the Prevents melt (5) and on the top edge of the tub (1) cannot have a hard crust (7) made of sintered metal form that would otherwise take a considerable amount of time that should. This will be a major improvement and Chilling process kept cheaper.
