Description

Verfahren und Vorrichtung zum kontinuierlichen kombinierten Glühen und Überziehen von Metalldraht Method and apparatus for the continuous combined annealing and coating of metal wire

Die Erfindung bezieht sich auf ein Verfahren zum kontinuierlichen kombinierten Glühen und überziehen von Metalldraht, insbesondere auf ein Glüh- und Verzinnungsverfahren für Kupferdraht, demgemäss der Metalldraht mittels Hindurchleiten eines elektrischen Stromes geglüht wird, wobei der Strom an zwei im Abstand voneinander befindlichen Eontaktstellen zwecks Erhitzens des Drahtes durch Wirkung seines elektrischen Widerstandes geleitet wird, und der Metalldraht mittels Durchführen durch ein Metallbad überzogen wird. Ferner bezieht sich die Erfindung auf eine Vorrichtung zur Durchführung dieses Verfahrens. The invention relates to a method for continuous combined annealing and coating of metal wire, in particular an annealing and tinning process for copper wire, Accordingly, the metal wire is annealed by passing an electric current through it, the current being applied to two im Eontaktstellen located at a distance from one another for the purpose of heating the wire through the action of its electrical resistance and the metal wire is coated by passing it through a metal bath. Furthermore, the Invention to an apparatus for performing this method.

Bei den heutzutage allgemein üblichen Heissverzinnungsverfahren gelangt der harte Kupferdraht durch Beizungs- und Gerinnungsbäder in einen Behälter mit geschmolzenem Zinn, wo derWith the hot-tinning processes commonly used nowadays the hard copper wire passes through the pickling and coagulation baths into a container of molten tin, where the

Bei einem anderen bekannten Verfahren hat man die Forderung aufgegeben,den Draht im Zusammenhang mit der Verzinnung zu glühen. Das Glühen wird hierbei in einer besonderen Widerstandsvorrichtung entweder vor dem Heissverzinnen oder danach ausgeführt. Another known method has the requirement abandoned annealing the wire in connection with the tinning. The glow is done in a special resistance device carried out either before or after hot tinning.

Die erwähnten bekannten Verfahren weisen verschiedene Nachteile auf. Fach erstgenannten Verfahren muss aufgrund der Glühforderung des Drahtes die Temperatur des Zinns erhöht oder die Tauchstrecke verlängert, d. h. der Behälter vergr-össer-t werden, wenn man die Schnelligkeit des Drahtes steigern möchte. Die Erhöhung der Zinntemperatur führt zur vermehrten Bildung der schädlichen Kupfer-ζinnverbindung, und der Zuwachs der Behältergrösse erfordert einen grösseren Wärmeeffekt und vermehrt die Neigung der Zinriflache zum Oxydieren. Ausserdem verursacht das Einführen der Beizungs- und Gerinnungsmittel mit dem Draht in das Zinn schädliche Zinnsalze und Asche im Behälter.The known methods mentioned have various disadvantages. The first-mentioned procedure must be carried out due to the annealing requirement the wire increases the temperature of the tin or increases the immersion distance, d. H. the container is enlarged if you want to increase the speed of the wire. The increase in the tin temperature leads to increased formation the harmful copper-tin compound, and the increase in container size requires a greater heat effect and increases the tendency of the tin surface to oxidize. Also caused introducing the pickling and coagulants with the wire into the tin harmful tin salts and ash in the container.

' Bei dem anderen Verfahren treten wieder folgende Nachteile auf: Geschieht das Glühen vor dem Verzinnen, ist die VerwendungIn the other method, there are again the following disadvantages on: If the annealing is done before tinning, the use

von Schutzgas zur Verhinderung des Oxydierens des Drahtes nötig. Ausserdem muss der Draht im Wasser nach dem Glühen abgekühlt werden, da es aus praktischen Gründen unmöglich ist, ihn völlig geschützt zum Verzinnen zu bringen. Geschieht das Glühen wieder nach dem Verzinnen, erfordert der Draht bei grösserer Schnelligkeit im Zinnbad eine längere Tauchstrecke oder höhere Zinntemperatur, da die Flächentemperatur des Drahtes wenigstens den Schmelzpunkt des Zinns erreichen muss, ehe das Zinn den Draht angreifen kann.shielding gas is necessary to prevent the wire from oxidizing. In addition, the wire has to be cooled down in the water after it has been annealed, since it is practically impossible to completely remove it to be tinned protected. If the annealing takes place again after tinning, the wire requires greater speed a longer immersion distance or higher tin temperature in the tin bath, since the surface temperature of the wire is at least the The tin must reach the melting point before the tin can attack the wire.

Die vorliegende Erfindung versucht die dargestellten Nachteile zu vermeiden. Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass der Metalldraht nach der ersten Kontaktstelle, jedoch vor der zweiten Kontaktstelle durch das Metallüberziehbad geführt wird.The present invention seeks to avoid the disadvantages shown. The inventive method is thereby characterized in that the metal wire passes through the metal plating bath after the first contact point, but before the second contact point to be led.

Der Vorteil des Verfahrens liegt darin, dass beim Glühen kein Schutzgas erforderlich ist, da die Zinnschicht das Kupfer vor Oxydieren schützt; Dies beruht darauf, dass die Temperatur des Metalldrahtes auf der Zwischenstrecke zwischen der ersten Kontaktstelle und dem Überziehbad noch nicht so weit angestiegen ist, dass schädliches Oxydieren vorkommen kann ,.und dass der Metalldraht auf der Strecke zwischen Überziehbad und der zweiten Kontaktstelle, wo die Temperatur des Drahtes schon genügend gestiegen ist, um ein Glühen zustandezubringen, durch den im Uberziehbad- erhaltenen Metallüberzug effektiv gegen Oxydieren geschützt ist. Die Temperatur des Zinns kann man auch so niedrigThe advantage of the process is that no protective gas is required during annealing because the tin layer is the copper protects against oxidation; This is due to the fact that the temperature of the metal wire on the intermediate distance between the first Contact point and the enrobing bath has not yet risen so far that harmful oxidation can occur, and that the metal wire on the section between the enrobing bath and the second contact point, where the temperature of the wire is already sufficient has risen to bring about a glow through which Effective against oxidation in the metal coating obtained in the coating bath is protected. The temperature of the tin can also be as low as that

wie möglich und die Tauchstrecke sehr kurz halten, da die Temperatur des zu dem Zinnbehälter kommenden Drahtes annähernd dem Schmelzpunkt des Zinns entspricht. Die Bildung von schädlichen Kupferzinnverbindungen ist daher sehr gering. Ausserdem bleibt der vom -,Zinnbehälter benötigte Wärmeeffekt sehr klein, da der Draht keiner Wärmeenergie bedarf, er kann vielmehr im Gegenteil dem Zinnbehälter Wärme abgeben, statt der durch Wärmeverluste verwendeten Energie.as possible and keep the diving distance very short, as the The temperature of the wire coming to the tin container approximately corresponds to the melting point of the tin. The formation of harmful Copper tin compounds is therefore very low. Besides that the heat effect required by the tin container remains very small, Since the wire does not require any thermal energy, it can, on the contrary, give off heat to the tin container instead of through heat losses energy used.

Die Beizungs- und Gerinnungsräder können oberhalb des Zinnbehälters liegen. Andererseits hat man beim Betrieb festgestellt, dass ein Draht,der direkt von der Ziehmaschine zur Vorrichtung nach Fig. 1 geführt ist, keine Überzug- und Gerinnungsstoffe erfordert, weil das Zinn trotzdem gut den Draht angreift.wheels 1 and 2 where the temperature of the wire is slightly above is the melting point of the tin, a tin container 6 is arranged. The pickling and coagulation wheels can be placed above the Tin container. On the other hand, it has been found during operation that a wire that goes directly from the drawing machine to the Device according to Fig. 1 is performed, does not require any coating and coagulants, because the tin is still good for the wire attacks.

Mit Hilfe eines Wärmewiderstandes 12 wird das Zinn geschmolzen, und seine Temperatur wird etwas über dem Schmelzpunkt des Zinns gehalten. Zum Durchführen des Drahtes durch den Zinnbehälter wird der Schieber 9 angehoben, so dass der Ziehstein 8 oberhalb der Zinnoberfläche zu liegen kommt. Wenn der Draht 3 nach Ingangsetzung der Maschine seine Arbeitsgeschwindigkeit erhalten hat und der Glühstrom eingeschaltet ist, schiebt man den Schieber 9 nach unten in die Lage nach Fig. 2. , . . .,,.: The tin container itself is illustrated in FIG.

So that the molten tin 1 does not escape from the container, existing seals 10 made of a heat-resistant material, for example asbestos, are arranged. The tin is melted with the aid of a thermal resistor 12 and its temperature is kept slightly above the melting point of the tin. To lead the wire through the tin container, the slide 9 is raised so that the drawing die 8 comes to rest above the tin surface.
