Description

Verfahren zum Glühen von Metallbändern in Durchziehöfen Wenn man Metallbänder in Durchziehöfen in der Weise glüht, daß sie, auf dem Boden der Öfen aufliegend, durch den Ofen hindurchgezogen werden, so stellt sich bei manchen Metallen, namentlich wenn die Bänder breit oder dick sind, der Übelstand heraus, daß sich auf der Unterseite des auf der Ofensohle schleifenden Bandes Risse oder Riefen bilden, die das Band minderwertig machen.Process for annealing metal strips in pull-through furnaces When using metal strips in pull-through ovens glows in such a way that, lying on the floor of the ovens, be pulled through the furnace, so it turns out with some metals, especially If the ligaments are wide or thick, the nuisance will come out on the underside cracks or grooves in the belt that rubs against the oven sole form, which form the belt make inferior.

Die vorliegende Erfindung verhindert die Bildung solcher Risse und Riefen dadurch, daß auf den Boden des Ofens ein Band aus Asbestpappe oder Asbestgewebe gelegt wird, das eine schützende Zwischenlage zwischen dem Metallband und der Ofensohle bildet. Dieses Asbestband wird zweckmäßig ständig oder absatzweise langsam durch den Ofen hindurchbewegt, damit die Teile des Asbestbandes, an welche sich Metallsplitter, oxydische Abfälle, Sand oder sonstige die Riefenbildung veranlassende Verunreinigungen gesetzt haben, aus dem Ofen entfernt werden.The present invention prevents the formation of such cracks and Scoring by putting a band of asbestos cardboard or asbestos fabric on the bottom of the stove is placed, which is a protective intermediate layer between the metal band and the furnace sole forms. This asbestos tape is expediently continuously or intermittently slowly moves the furnace through so that the parts of the asbestos tape to which metal splinters oxidic waste, sand or other impurities that cause scoring have to be removed from the oven.
