Description

Verfahren zum kontinuierlichen Wärmebehandeln von Drähten, Bändern, Rohren od. dgl. Die Erfindung bezieht sich auf ein Verfahren zum kontinuierlichen Wärmebehandeln von vergütbaren Metallegierungen, insbesondere zum Vergüten von Drähten, Bändern, Rohren od. dgl. aus Stählen, unter Anwendung der elektrischen Widerstandserwärmung durch Stromdurchgang, wobei die Erwärmung zum Härten und Anlassen in einem einzigen Stromdurchgang hintereinander vorgenommen wird und durch entsprechende - Verschiebung einer Abschreckdüse insbesondere die Anlaßtemperatur geregelt wird, nach Patent 886 6o5.Process for the continuous heat treatment of wires, strips, Tubes od. The like. The invention relates to a method for continuous Heat treatment of heat treatable metal alloys, especially for heat treatment of wires, Strips, pipes or the like made of steels, using electrical resistance heating by passage of current, with heating for hardening and tempering in a single Current passage is made one after the other and by corresponding - shift a quenching nozzle, in particular, the tempering temperature is regulated, according to patent 886 6o5.

Sie bezweckt, bei solchen Metallegierungen bzw. Stählen, deren Festigkeit nach dem eigentlichen Anlassen noch zu hoch liegt, eine Nacherwärmung vorzunehmen, d. h., die Anlaßtemperatur einige Zeit aufrechtzuerhalten oder aber die Abkühlungs< geschwindigkeit nach dem eigentlichen Anlassen durch eine zusätzliche geringere Widerstandserhitzung nach dem Durchgang durch den bisher vorgesehenen Auslaufkontakt zu verlangsamen.The purpose of such metal alloys or steels is to increase their strength is still too high after the actual start-up to carry out reheating, d. That is, to maintain the tempering temperature for some time, or else to keep the cooling temperature up speed after the actual starting by an additional lower Resistance heating after passing through the previously provided outlet contact to slow down.

Letzteres kann in einfacher Weise dadurch erfolgen, daß entweder als Stromquelle für die Nachwärmung ein vom Haupttransformatorunabhängiger weiterer Transformator verwendet oder eine zweite Sekundärwicklung des Haupttransformators benutzt wird. Die letztere Anordnung hat den Vorteil, daß sich die Spannung zwischen den nach dem Hauptpatent vorgesehenen Hauptkontakten bzw. dem letzten .Hauptkontakt und dem nachzuschaltenden Nebenkontakt, wobei letzterer aus dem Antriebsaggregat, bestehend aus der Aufwickelhaspel, den_ Transportwalzen od.dgl. öder einer weiteren besonderen Kontaktvorrichtung bestehen kann, in gleicher Weise verändern läßt, wenn z. B. mit verschiedenen Durchlaufgeschwindigkeiten gearbeitet wird.The latter can be done in a simple manner that either as Power source for reheating is an additional one that is independent of the main transformer Transformer used or a second secondary winding of the main transformer is used. The latter arrangement has the advantage that the voltage between the main contacts provided for in the main patent or the last main contact and the secondary contact to be connected, the latter consisting of the drive unit, existing from the take-up reel, den_ transport rollers or the like. or another special one Contact device can exist, can change in the same way if, for. B. with different throughput speeds are used.

Die Nachwärmtemperatur bzw. die Abkühlungsgeschwindigkeit können hierbei durch Veränderung des Abstandes zwischen dem letzten Hauptkontakt und dem nachzuschaltenden Nebenkontakt in einfacher Weise geregelt werden. ...-The reheating temperature or the cooling rate can be used here by changing the distance between the last main contact and the one to be connected Secondary contact can be regulated in a simple manner. ...-
