 hervortretenden Bleche tritt. Das dem Bleche anhaftende, flüssige Zink kommt hiedurch zur Erstarrung, bevor es genügend Zeit gehabt hat, abzufliessen. Der Zinkbelag fällt infolgedessen zu dick aus, was bei   geringwertigen   Dachblechen zu teuer wird. 



   Um diesen   Übelstand   zu verhüten, sind im Zinkbad zwei verschiebbare Zwischen-   wände 11,   beispielsweise aus feuerfesten Ziegeln, angeordnet. Diese Zwischenwände. ragen einige Zoll aus dem Zinkbade hervor, so dass ein warmes Luftlager zwischen ihnen gebildet wird, wodurch ein zu rasches   Abkühlen des geschmolzenen Zinkes verhindert   wird. 



   Je näher diese Zwischenwände an das Blech herangeführt werden, desto dünner wird der Zinkbelag. Dies geht jedoch nur bis zu einer bestimmten Grenze, denn wenn die Wände zu nahe aneinander herankommen, hindern dieselben das herabfliessende abgekühlte Zink, sich mit dem heissen Zinkbad zu vermischen, wodurch ein dickerer    Zink-belag, gebildet würde.   



   Da diese günstigste Entfernung teils von der Dicke des Bleches, teils von der Temperatur des Zinkbades und der Luft sowie von der Geschwindigkeit der Bewegung abhängig ist, so ist

 struktion mit der endlosen Kette. Ein weiterer Grund, die Zwischenwände verstellbar zu machen, ist der Umstand, dass man für verschiedene Zwecke verschieden dicken Zinkbelag wünscht.

 protruding sheet metal occurs. The liquid zinc adhering to the sheet solidifies before it has had enough time to flow off. As a result, the zinc coating is too thick, which is too expensive for low-quality roofing sheets.



   In order to prevent this inconvenience, two movable partition walls 11, for example made of refractory bricks, are arranged in the zinc bath. These partitions. protrude a few inches from the zinc bath so that a warm air layer is formed between them, preventing the molten zinc from cooling too quickly.



   The closer these partitions are brought to the sheet metal, the thinner the zinc coating becomes. However, this only works up to a certain limit, because if the walls come too close to one another, they prevent the cooled zinc flowing down from mixing with the hot zinc bath, whereby a thicker zinc coating would be formed.



   Since this most favorable distance depends partly on the thickness of the sheet, partly on the temperature of the zinc bath and the air, and on the speed of movement, so is

 construction with the endless chain. Another reason to make the partition walls adjustable is the fact that you want zinc covering of different thicknesses for different purposes.

 

Claims (1)

PATENT-ANSPRUCH : Verzinkvorrichtung mit Blei-und Zinkbad, bei der in dem das Bleibad enthaltenden Kessel ein kleinerer das Zink aufnehmender Behälter angeordnet ist. dessen Wände durch Ziegel vor dem Angriffe des Zinkes geschützt sind und der durch Zwischenwände unterteilt ist, die über die Oberfläche des Zinkbades reichen, dadurch gekennzeichnet, dass die Zwischenwände (11) verschiebbar angeordnet sind und gleichzeitig zum Ausheben der verzinkten Bleche eine endlose Kette (6) vorgesehen ist, in deren Glieder eine von Hand geführte Greifzange (9) mit einem Ansatz (10) eingehängt wird. PATENT CLAIM: Galvanizing device with lead and zinc bath, in which a smaller container is arranged in the tank containing the lead bath. the walls of which are protected from the attack of zinc by bricks and which are divided by partition walls that extend over the surface of the zinc bath, characterized in that the partition walls (11) are arranged to be displaceable and at the same time an endless chain (6 ) is provided, in the links of which a hand-held gripper (9) with a shoulder (10) is suspended.
