Abstract

Industrieofen mit Luftumwälzung für Wärmebehand­ lungsverfahren mit einer höheren Strömungsgeschwindig­ keit bei gleichzeitiger Verkürzung der Aufheizzeit und einer Verringerung der Temperaturdifferenzen im Ofen während des Aufheizens und während der Glühbehandlung durch in dem Raum zwischen der Charge und den Ofenwänden den Luftstrom beeinflussende Elemente (Hindernisse, Leitbleche oder dgl.), die starr oder beweglich z.B. verschwenkbar sein können und in manchen Fällen den Chargenelementen angepaßt sind, so daß sie praktisch ein Spiegelelement der äußeren Fläche der Charge darstellen.
