Abstract

Ein Durchlaufofen (10) dient zum Wärmen und anschli­ eßenden Abkühlen von Werkstücken unter Schutzgas­ atmosphäre, insbesondere Sinterteilen (19). Er weist einen Ofenteil (15) und einen Kühlteil (16) auf, die von einem Förderband durchsetzt sind.
Um den Durchlaufofen optimal an vorhandene Raumver­ hältnisse am Einsatzort anpassen zu können, sind der Ofenteil (15) und der Kühlteil (16) als auf räumlich versetzten Ebenen getrennte Einheiten mit jeweils einem eigenen Förderband (20, 32) ausgebildet. Das Ende des Förderbandes (20) des Ofenteils (15) ist oberhalb des Anfanges des Förderb­ andes (32) des Kühlteiles (16) angeordnet und die Sinterteile (19) gelangen unter Schwerkrafteinfluß von dem Ende auf den Anfang.
