Description
Die Erfindung betrifft ein Verfahren .und. eine Vorrichtung zum kontinuierlichen Glühen und Vergüten von Bändern oder D.rä&hten insbesondere aus Aluminium oder Aluminiumlegierungen.The invention relates to a method .und. a device for continuous Annealing and quenching and tempering of strips or wires, in particular made of aluminum or Aluminum alloys.
Es sind Verfahren zur Vergütung von metallenen Bändern bekannt, wobei das zu behandelnde Gut aufgewickelt in einem Glühofen auf die erforderliche Temperatur gebracht und nachträglich, z. B. durch Tauchen in ein Wasserbad, abgeschreckt wind.There are known methods for the remuneration of metal strips, wherein the material to be treated is wound up in an annealing furnace to the required temperature brought and subsequently, z. B. by immersing in a water bath, wind deterred.
Bei einem anderen bekannten Verfahren werden ,die Bänder durch einen Durchziebofen gezogen und bei ihrem Austritt aus dem Ofen abgeschreckt.In another known method, the tapes are through a Pulled through the pull-through furnace and quenched as it exits the furnace.
Obwohl durch diese Verfahren eine ziemlich gleichmäßige Erhitzung tdes Glühgutes erfolgt, lassen -sie bei der Vergütung von Aluminium deswegen zu wünschen übrig, weil die blankgewälzten Alumin.i,wm@bänder bzw. -drähte tretsprechend ihrer niedrigen- Strahlungszahl ein ungünstiges Wärmeaufnahmevermögen haben. Dies bringt den Nachteil mit sich, @daß große Schwankungen in der Materialqualität auftreten und daß, um mittels eines Durchziehofens eine hinreichende Glühungherbeizu@führen, diese letzteren sehr lang und umständlich in der Bedienung werden.Although by this procedure a fairly uniform heating When the annealing material takes place, allow them to be used in the tempering of aluminum to be desired, because the bright-rolled alumin.i, wm @ strips and wires are appropriate their low radiation number have an unfavorable heat absorption capacity. this has the disadvantage that there are large fluctuations in the quality of the material and that, in order to achieve sufficient annealing by means of a pull-through oven, the latter become very long and cumbersome to use.
Die Erfirndiung hat sich zur Aufgabe gestellt, unter Beseitigung der vorstehend beschriebenen Nachteile ein kontinuierlich. arbeitendes Verfahren zu .entwickeln, ,das mittels einer besonders einflachen un:d'einen,geringen Raum erfordernden Vorrichtung durchgeführt werden kann.The invention has set itself the task of eliminating the disadvantages described above a continuously. working procedure too .develop, that by means of a particularly flat un: d'requiring little space Device can be carried out.
Das Verfahren nach oder Erfindung kennzeichnet sich dadurch, daß die Glühun@g der Bänder bzw. Drähte dadurch bewirkt wird,daß indem eine kurzgeschlossene Schleife bildenden Band bzw. Draht ein Induktionsstrom erzeugt wird. Am zweckmäßigsten ist es, wenn. das zu behandelnde Band bzw. -der Draht unter Bildung einer Schleife durch ein Triowalzwerk geführt wird, dessen, Walzen den elektrischen Kurzschl.uß ider Band- bzw. Drahtschleife bewirken.The method according to or invention is characterized in that the Annealing of the strips or wires is effected by adding a short-circuited Loop-forming tape or wire an induction current is generated. Most convenient is it when. the tape or wire to be treated, forming a loop is passed through a trio rolling mill, the rollers of which the electrical short-circuit cause the ribbon or wire loop.
Eine besonders zweckmäßige und gedrängte Vorrichtung zur Ansführu.ng des Verfahrens nach -der Erfindung ergibt sich, wenn,die Band- :bzw. Drahtschleife ;die Primärspule und den Kern eines elektrischen Transformators umfaßt. Ein Verfahren zum fortlaufenden Erwärmen (Glühen) von Metallbändern mittels mehrphasigen Wechselstroms normaler oder höherer Frequenz ist bekannt. Das Band wird bei idem .bekannten Verfahren dadurch erwärmt, @daß es ein Wanderfeld .durchläuft, wobei die Fortbewegungsrichtung des Banides mit der Wanderrichtung des Feldes gleich ist, so daß Idas Band dadurch ein Triebmoment erhält.A particularly useful and compact device for Ansführu.ng of the method according to the invention results when the tape: or. Wire loop ; comprises the primary coil and the core of an electrical transformer. A procedure for continuous heating (annealing) of metal strips by means of multiphase alternating current normal or higher frequency is known. The tape is in the. Known method heated by @ that it. passes through a traveling field, the direction of movement of the banides is the same as the direction of travel of the field, so that Ida's bond through it receives a driving moment.
Die Zeichnung zeigt beispielsweise eine Au@sführüngsform der Erfindung.The drawing shows, for example, an embodiment of the invention.
Das Band i- durchläuft in Richtung .der eingezeichneten Pfeile die Walzspalte des Triowalzwerkes, 2. In der geschlossenien Bandschleife, die das Band zwischen dem Eintrittsspalt und dem Austrittsspalt der Walzen 2 bildet, befinden sich die ,Primärspule 3 mit ,dem lamellierten eisernen Blechkern ¢. Die benötigte elektrische. Eniergie zur Erwärmung des Bandes i wind mit Hilfe der Klemmen 5 der Primärspule 3 einem Wechselstromnetz entnommen. ZurAbkühlu:ng bzw. Abschreckung des Bandes Bind an der Austrittsseite des Walzwerks 2 Sprührollen 6 angeordnet.The band i- runs in the direction of the arrows Roll gap of the trio rolling mill, 2. In the closed belt loop that the belt between the entry gap and the exit gap of the rollers 2 are located the, primary coil 3 with, the laminated iron sheet core ¢. The one needed electrical. Energy for heating the band i wind with the help of the clamps 5 of the Primary coil 3 taken from an alternating current network. For cooling or deterrence of the band Bind on the exit side of the rolling mill 2 spray rollers 6 arranged.
