Abstract

Inductive annealing of high-alloy welding and resistance wires during drawing is carried out by passing the wires after each cold drawing stage through an induction circuit and subjecting them to intermediate annealing without interrupting the continuity of drawing. The temps. reached during annealing depend on the chemical compsn. of the wires. Method allows drawing to be performed continuously until the desired final size is reached.

Description

Induktives Glühen von Drähten, insbesondere aber legierten Inductive annealing of wires, especially alloyed ones

und hochlegierten Schweißdrähten. während des Ziehprozesses. and high-alloy welding wires. during the drawing process.

Die Erfindung betrifft eine induktive Glühung von Drähten, insbedondere aber von legierten und hochlegierten Schweißdrähten und Widerstandsdrähten. Drähte und insbesondere Schweißdrähte werden bekanntlich überwiegend kaltgezogen. Da sich bei diesem Kaltziehprozess die Drähte, insbesondere abr hochlegierte Drähte stark verfestigen, ist es notwendig, Zwischenglühungen, die ein Entspannen der verzerrten Gitterstruktur bewirken, vorzunehmen. Dieses Zwischenglühen findet je nach chemischer Zusammensetzung der entsprechenden Drähte oft nach jedem Ziehgang statt. Die jeweiligen Zwischenglühungen werden in einem Glühofen durchgeführt, indem man die zu glühenden Drähte auf Spulen unterschiedlichen Gewichtes aufhaspelt und damit den Glühen beschickt.The invention relates to an inductive annealing of wires, in particular but of alloyed and high-alloy welding wires and resistance wires. Wires and in particular welding wires are known to be predominantly cold drawn. That I In this cold drawing process the wires, especially high-alloy wires, are strong solidify, it is necessary to perform intermediate anneals that relax the distorted Cause lattice structure to make. This intermediate annealing takes place depending on the chemical Composition of the appropriate wires often takes place after each draw. The respective Intermediate anneals are carried out in an annealing furnace by adding the ones to be annealed Coiling wires on spools of different weights and feeding them into the glow.

Der Erfindung liegt die Aufgabe zu Grunde, den Ziehvorgang, der bisher durch Zwischenglühungen unterbrochen wird, kontinuierlich bis zum erforderlichen Endmaß durchzuführen.The invention is based on the object, the drawing process, which so far is interrupted by intermediate annealing, continuously until required To carry out final dimension.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß d#r jeweilige Draht, wenn erforderlich, nach jedem Ziehgang durch eine Induktionsechleife geführt wird.This object is achieved according to the invention in that the respective Wire, if necessary, fed through an induction loop after each draw will.

Während des Durchlaufs wird der Draht induktiv kontinuierlich geglüht. Die nach chemischer Zusammensetzung unterschiedlichen Glühtemperaturaturen sind stufenlos regelbar.During the run, the wire is inductively annealed continuously. The annealing temperatures are different according to their chemical composition infinitely variable.
