Abstract

Die Erfindung betrifft einen Hochdrucksinterofen, der nach Beendigung des Sinterprozesses schnell abgekühlt werden kann. Die Abkühlung wird dadurch beschleunigt, dass in dem Sinterofen ein inertes Gas zum Zirkulieren gebracht wird, das seine Wärme an einen Wärmetauscher abgibt und dass die Kühleinrichtung asymmetrisch zur Achse des Hochdruksinterofens angeordnet ist.
