Gegenstand der Erfindung· ist ein Verfahren zum Bräunieren langer, zu Rollen aufgewickelter Blechstreifen, sogenannter endloser Bleche, in ununterbrochenem Arbeitsgang, bei dem die Blechstreifen entsprechend dem bekannten Lackierverfahren für endlose Blechstreifen von Rollen abgewickelt, durch eine Bräunierungsbeize geleitet, getrocknet und nach geschehener Bräunierung sofort wiederThe subject matter of the invention is a method for browning long ones wound into rolls Sheet metal strips, so-called endless sheets, in an uninterrupted operation which the sheet metal strips according to the known painting process for endless sheet metal strips unwound from rolls, passed through a browning stain, dried and immediately after tanning

ίο aufgewickelt werden. Bei Lackierverfahren ist der Arbeitsgang ein sehr langsamer, da die lackierten Blechstreifen; längere Zeit zum Trocknen brauchen und hierzu bisher in vielen Windungen durch große Trockenöfen oder auch langsam durch stark beheizte Röhren geleitet werden, welche die Gefahr mit sich bringen, daß der aufgetragene Lack verbrennt. ίο be wound up. In painting processes the operation is a very slow one because the painted metal strips; longer time to Need drying and this so far in many turns by large drying ovens or can also be passed slowly through highly heated tubes, which are dangerous bring that the applied paint burns.

ao findung wird der Arbeitsvorgang beschleunigt und außerdem der Blechstreifen auf beiden Seiten mit dem rostschützenden Überzug versehen. Um das Bräunieren in einem Arbeitsgang und in möglichist kurzer Arbeitszeit vornehmen zu können, werden nach der Erfindungf die Blechstreifen, wenn sie dias Bräunierungsbeizbad verlassen haben, undi noch mit der Beize behaftet sind, durch einen Brenn- und Trockenraum mit offenen Flammen geleitet. In diesem Brenn- und Trockenraum wird die Beize, indem die Bänder mehrere offene Flammen durchlaufen, zunächst äußerst konzentriert und dadurch höchst wirksam, und dann werden die Beizrückstände durch die Wärmewirkung der Flammen getrocknet und gleichzeitig in die Oberfläche der Blechstreifen eingebrannt. Die Einwirkung der Beize ist dadurch so groß, daß durch eine einmalige Behandlung der Blechstreifen eine gute und dauerhafte Bräunierung erzielt wird.Ao finding the work process is accelerated and also the sheet metal strips on both The sides are provided with the anti-rust coating. All about tanning in one go and in a short working time is possible, according to the invention f the sheet metal strips when they have left the tanning bath, andi still with the stain are affected, passed through a combustion and drying room with open flames. In this firing and drying room, the stain is made by placing the belts several Passing through open flames, initially extremely concentrated and therefore highly effective, and then the pickling residues are dried by the heat of the flames and at the same time burned into the surface of the metal strips. The action of the The stain is so large that a one-time treatment of the sheet metal strips good and lasting tan is achieved.

Eine zur Ausführung dieses Verfahrens dienende Vorrichtung ist auf der Zeichnung· als Ausfuhrungsbeispiel in schematischer Darstellung veranschaulicht.A device used to carry out this process is shown in the drawing illustrated as an exemplary embodiment in a schematic representation.

Der durch strichpunktierte Linien angedeutete Blechstreifen 1 läuft von der Rolle 2 ab und wird durch den mit geeigneter Bräunierungsbeize gefüllten Beizebehälter 3 in den Brenn- und Trockenraum 4 geleitet. In diesem wird der Blechstreifen über eine Flammenreihe S von geeigneter Länge geführt, welche die dem Blechstreifen anhaftende Beizflüssigkeit trocknet und einbrennt. Die dem Blechstreifen noch lose anhaftenden Rückstände der Beize werden von Abstreichern 6, welche der Blechstreifen beim Verlassen des Brenn-undTrockenraumes 4 passiert, entfernt, und dann wird der fertig bräunierte Blechstreifen durch die Polierwalzen 7 poliert und sofort zu der Rolle 8 aufgewickelt.The sheet metal strip 1 indicated by dash-dotted lines runs from the roll 2 and is filled with the pickling container 3 with a suitable browning stain in the Combustion and drying room 4 passed. In this the sheet metal strip is placed over a row of flames S guided of a suitable length, which the pickling liquid adhering to the sheet metal strip dries and burns in. The residues still loosely adhering to the metal strip the stain are scrapers 6, which the sheet metal strips when leaving the Firing and drying room 4 happened, removed, and then the finished browned sheet metal strip is polished by the polishing rollers 7 and immediately wound up into the roll 8.

In einer Bräunierungsvorrichtung werden zweckmäßig mehrere Blechstreifen nebeneinander! gleichzeitig bräuniert, was durch) Verbreiterung der Vorrichtung ohne weiteres durchführbar ist.In a browning device, several metal strips are expediently next to each other! browned at the same time, which can be easily carried out by) widening the device.
