Abstract

Bei einem Verfahren zum Herstellen von Feindraht, insbesondere Kratzendraht, bei dem ein ggf. bereits behandeltes, insbesondere gezogenes, Draht-Ausgangsmaterial durch einen Wärmebehandlungsvorgang in einen ziehfähigen Zustand versetzt, dann gezogen und anschließend zum Erhalt vorgegebener mechanischer Eigenschaften vergütet wird, wird eine Weiterbildung vorgeschlagen, bei der der gezogene Draht zum Vergüten mindestens eine zuvor bereits zur Durchführung des Wärmebehandlungvorganges eingesetzte Ofen- und/oder Abkühleinrichtung durchläuft.In a method for producing fine wire, in particular Scratch wire, in which a possibly already treated, in particular drawn, wire raw material by a heat treatment process put in a drawable state, then pulled and then to get predetermined mechanical Further training is proposed, in which the drawn wire to temper at least one beforehand already used to carry out the heat treatment process Passes through furnace and / or cooling device.
