Abstract
Bei einem Verfahren zum Verzinken von Draht tritt der Draht (4) senkrecht aus einem Zinkbad (1) aus. Das anhaftende flüssige Zink bildet nach seiner Erstarrung die Zinkschicht. Zwecks Vergrößerung der Schichtdicke des anhaftenden Zinks wird die Oberfläche des Drahtes unmittelbar nach seinem Austritt aus dem Zinkbad durch ein Kühlmedium, vorzugsweise flüssigen Stickstoff, stark abgekühlt.In a method for galvanizing wire, the wire (4) emerges vertically from a zinc bath (1). The adhering liquid zinc forms the zinc layer after it solidifies. In order to increase the layer thickness of the adhering zinc, the surface of the wire is strongly cooled by a cooling medium, preferably liquid nitrogen, immediately after it emerges from the zinc bath.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verzinken von Draht, bei denen der Draht senkrecht aus einem Zinkbad austritt und das anhaftende flüssige Zink nach seiner Erstarrung die Zinkschicht bildet. Je nach Drahtgeschwindigkeit, Badtemperatur, Drahtabmessung und ähnlichen Einflüssen fließt ein gewisser Teil des am Draht anhaftenden flüssigen Zinks in das Bad zurück. Dadurch stellt sich eine bestimmte Dicke der auf dem Draht verbleibenden Zinkschicht ein. Für manche Anwendungsgebiete ist die auf diese Weise erreichbare Zinkschicht zu dünn.The invention relates to a method and a device for galvanizing wire, in which the wire emerges vertically from a zinc bath and the adhering liquid zinc forms the zinc layer after it has solidified. Depending on the wire speed, bath temperature, wire size and similar influences, a certain part of the liquid zinc adhering to the wire flows back into the bath. This results in a certain thickness of the zinc layer remaining on the wire. The zinc layer that can be achieved in this way is too thin for some areas of application.
Man hat versucht, eine dickere Zinkschicht dadurch zu erreichen, daß man den Draht unmittelbar nach Austritt aus dem Zinkbad einer Gasatmosphäre aussetzte, die Schwefelwasserstoff als aktive Komponente enthielt. Schwefelwasserstoff ist jedoch ein sehr giftiges und chemisch sehr aggressives Gas, so daß die Realisierung einer solchen Verfahrensweise in der Praxis Schwierigkeiten bereitet.Attempts have been made to achieve a thicker zinc layer by exposing the wire to a gas atmosphere immediately after leaving the zinc bath Contained hydrogen sulfide as an active component. However, hydrogen sulfide is a very toxic and chemically very aggressive gas, so that the implementation of such a procedure is difficult in practice.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Verzinken von Draht zu schaffen, bei denen der Draht senkrecht aus dem Zinkbad austritt und das anhaftende flüssige Zink nach seiner Erstarrung die Zinkschicht bildet, welche ohne die Zuhilfenahme giftiger und aggressiver Medien eine Vergrößerung der Schichtdicke des anhaftenden Zinks ermöglichen.The invention is therefore based on the object to provide a method and a device for galvanizing wire, in which the wire emerges vertically from the zinc bath and the adhering liquid zinc forms the zinc layer after its solidification, which without the aid of toxic and aggressive media Allow increasing the layer thickness of the adhering zinc.
Erfindungsgemäß wird dies dadurch erreicht, daß die Oberfläche des Drahtes unmittelbar nach seinem Austritt aus dem Zinkbad durch ein Kühlmedium stark abgekühlt wird.According to the invention, this is achieved in that the surface of the wire is strongly cooled by a cooling medium immediately after it emerges from the zinc bath.
Hierdurch wird ein rasches Erstarren des auf dem Draht befindlichen flüssigen Zinks bewirkt, die Menge des vom Draht abfließenden Zinks wird also vermindert. Die Schichtdicke wird dadurch vergrößert.This causes the liquid zinc on the wire to solidify rapidly, thus reducing the amount of zinc flowing off the wire. This increases the layer thickness.
Die Abkühlung kann durch direkten Kontakt der Oberfläche des Drahtes mit dem Kühlmedium, beispielsweise durch Besprühen, erfolgen. Ggf. kann hierbei das verdampfte Kühlmedium auch zusätzlich als Schutzgas für die noch empfindliche Oberfläche des verzinkten Drahtes verwendet werden. Die Oberfläche des Drahtes kann jedoch auch indirekt abgekühlt werden, indem er nach Austritt aus dem Zinkbad durch eine ihn umgebende Kammer geführt wird, deren Innenwand durch das Kühlmedium gekühlt wird. Bevorzugt wird als Kühlmedium ein tiefsiedendes, verflüssigtes Gas, beispielsweise Stickstoff. Der verdampfte Stickstoff kann als Schutzgas für den noch empfindlichen verzinkten Draht verwendet werden. Er kann auch als Trägergas für ein Reaktionsgas wie Amoniak oder Schwefelwasserstoff verwendet werden.The cooling can take place by direct contact of the surface of the wire with the cooling medium, for example by spraying. Possibly. the evaporated cooling medium can also be used as a protective gas for the still sensitive surface of the galvanized wire. However, the surface of the wire can also be cooled indirectly by passing it out of the zinc bath through a surrounding chamber, the inner wall of which is cooled by the cooling medium. A low-boiling, liquefied gas, for example nitrogen, is preferred as the cooling medium. The evaporated nitrogen can be used as a protective gas for the still sensitive galvanized wire. It can also be used as a carrier gas for a reaction gas such as ammonia or hydrogen sulfide.
Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens mit direktem Kontakt zwischen verzinktem Draht und Kühlmedium besteht aus einem Rohr, welches den aus dem Zinkbad austretenden Draht umgibt, in das Zinkbad eintaucht und kurz über der Oberfläche des Zinkbades von einer Ringkammer umgeben ist, die eine Zuleitung für flüssigen Sauerstoff besitzt und auf den Draht gerichtete Sprühöffnungen für flüssigen Sauerstoff aufweist. Im Bereich der Eintauchstelle in das Zinkbad besteht das Rohr vorzugsweise aus einem Isolationsmaterial, beispielsweise einer Oxydkeramik, die den Wärmezufluß in die Ringkammer hemmt.A device for carrying out the method according to the invention with direct contact between the galvanized wire and the cooling medium consists of a tube which surrounds the wire emerging from the zinc bath, dips into the zinc bath and is surrounded by an annular chamber just above the surface of the zinc bath which has a feed line for it has liquid oxygen and has spray openings for liquid oxygen directed onto the wire. In the area of the immersion point in the zinc bath, the tube preferably consists of an insulation material, for example an oxide ceramic, which inhibits the flow of heat into the annular chamber.
Die Zeichnungen veranschaulichen in schematischer Form zwei Ausführungsbeispiele der Erfindung im Schnitt.The drawings illustrate in schematic form two exemplary embodiments of the invention in section.
Es zeigen:
- Fig. 1 eine Vorrichtung für direkten Kontakt zwischen Drahtoberfläche und Kühlmedium,
- Fig. 2 eine Vorrichtung für indirekten Kontakt zwischen Drahtoberfläche und Kühlmedium.
- 1 shows a device for direct contact between the wire surface and the cooling medium,
- Fig. 2 shows a device for indirect contact between the wire surface and the cooling medium.
In Fig. 1 ist ein Zinkbad dargestellt, aus dem mit Hilfe der Umlenkrollen 2, 3 der zxverzinkende Draht senkrecht nach oben austritt. Erfindungsgemäß ist der Draht 4 von einem Rohr 5 umgeben, welches mittels eines konischen übergangsstückes 6 in eine Ringkammer 7 übergeht. Die Ringkammer 7 ist unmittelbar über der Austrittsstelle des Drahtes 4 aus dem Zinkbad 1 angeordnet. In Verlängerung des Rohres 5 schließt sich unterhalb der Ringkammer 7 ein weiteres Rohr 8 an, welches in das Zinkbad 1 eintaucht. Dieses Rohr 8 besteht zumindest im Bereich der Eintauchstelle aus einem Isolationsmaterial 9, welches die Wärmezufuhr aus dem Zinkbad 1 in die Ringkammer 7 hemmt.In Fig. 1, a zinc bath is shown, from which, with the aid of the
An die Ringkammer 7 ist eine Zuleitung 10 für flüssigen Stickstoff angeschlossen. Der flüssige Stickstoff tritt durch Sprühdüsen 11 aus, die auf den Draht 4 gerichtet sind. Wegen der tiefen Kälte des flüssigen Stickstoffs erstarrt das sich auf dem Draht befinddene flüssige Zink im Bereich der Sprühstelle sofort. Es hat keine Möglichkeit, am Draht 4 zurück in das Zinkbad 1 zu fliessen. Es ergibt sich dadurch eine wesentlich dickere Zinkschicht, als sie ohne die erfindungsgemäße Maßnahme erreichbar wäre.A feed line 10 for liquid nitrogen is connected to the annular chamber 7. The liquid nitrogen exits through spray nozzles 11 which are directed onto the wire 4. Because of the deep coldness of the liquid nitrogen, the liquid zinc on the wire solidifies immediately in the area of the spray point. It is not possible to flow back into the zinc bath 1 on the wire 4. This results in a much thicker zinc layer than would be achievable without the measure according to the invention.
Der verdampfte Stickstoff strömt durch das Rohr 5 nach oben und tritt aus der Anlage aus. Er wirkt hier als Schutzgas für die noch empfindliche Zinkschicht. Falls gewünscht, können in das Rohr 5 zusätzlich noch Reaktionsgase wie Amoniak, Schwefelwasserstoff oder gasförmige oder flüssige Kohlenwasserstoffe eingeführt werden.The vaporized nitrogen flows through the tube 5 upwards and exits the system. Here it acts as a protective gas for the still sensitive zinc layer. If desired, reaction gases such as ammonia, hydrogen sulfide or gaseous or liquid hydrocarbons can additionally be introduced into the tube 5.
Fig. 2 zeigt eine Vorrichtung zur indirekten Kühlung des aus dem Zinkbad 1 austretenden Drahtes 4. Diese Vorrichtung besteht im wesentlichen aus einem doppelwandigen Rohr, dessen beide Rohre-i2,13 oben und unten durch Ringflansche 14,15 miteinander verbunden sind. Es wird somit eine Ringkammer 16 gebildet, die vom Kühlmittel durchflossen wird. Die Ringkammer 16 besitzt eine Zuleitung 17 und eine Ableitung 18 für das Kühlmittel.2 shows a device for indirect cooling of the wire 4 emerging from the zinc bath 1. This device essentially consists of a double-walled tube, the two tubes-i2, 13 of which are connected to one another at the top and bottom by
Die Strömungsrichtung ist durch Pfeile 19 angedeutet, desgleichen die Bewegungsrichtung des Drahtes 4 durch einen Pfeil 20. Diese Vorrichtung ist vor allem für solche Kühlmedien gut geeignet, die während des Kühlvorganges nicht verdampfen, sondern flüssig bleiben, also Kühlmedien, die in unterkühltem Zustand in die Vorrichtung eingeführt werden.The direction of flow is indicated by
