Title (EN) APPARATUS FOR TREATING A METAL STRIP
(FR) DISPOSITIF POUR LE TRAITEMENT D'UNE BANDE MÉTALLIQUE
(DE) VORRICHTUNG ZUM BEHANDELN EINES METALLBANDES
Abstract:
(EN) The invention relates to an apparatus for treating a metal strip after said metal strip has exited a coating tank having liquid coating material, such as zinc. Known apparatuses of said type have: a cleaning blower (110) arranged above the coating tank (300) and having an air outlet gap (112) for blowing out excess parts of the still liquid coating material (310) from the surface of the metal band (200) after passing the metal strip (200) through the coating tank (300) and an electromagnetic stabilization device (140) arranged above the blower (110) and having a plurality of individual magnets (144) for stabilization of the metal strip after exiting the coating tank (300) and the blower (110). In order to further increase the efficiency of the device, according to the invention, at least individual magnets (144) of the stabilization device (140) are designed as pot magnets having a pot coil.
(FR) L'invention concerne un dispositif pour le traitement d'une bande métallique après la sortie de celle-ci d'une cuve de revêtement contenant un matériau de revêtement liquide, p. ex. du zinc. Des dispositifs connus de ce genre comprennent : un dispositif de soufflage (100) disposé au-dessus de la cuve de revêtement (300) comprenant une fente de sortie d'air (112) pour éliminer par soufflage des partie excédentaires du matériau de revêtement (310) encore liquide de la surface de la bande métallique (200) après le passage de la bande métallique (200) à travers la cuve de revêtement (300) et un dispositif de stabilisation électromagnétique (140) disposé au-dessus du dispositif de soufflage (110), comprenant une pluralité d'aimants individuels (144) pour la stabilisation de la bande métallique après sa sortie de la cuve de revêtement (300) et du dispositif de soufflage (110). Pour augmenter l'efficacité du dispositif, au moins certains des aimants (144) du dispositif de stabilisation (140) sont réalisés selon l'invention sous forme d'aimants cuirassés avec une bobine à noyau en pot.
(DE) Die Erfindung betrifft eine Vorrichtung zum Behandeln eines Metallbandes, nachdem dieses aus einem Beschichtungsbehälter mit flüssigem Beschichtungsmaterial, z. B. Zink, ausgetreten ist. Bekannte Vorrichtungen dieser Art weisen auf: Eine oberhalb des Beschichtungsbehälters (300) angeordnete Abblaseinrichtung (110) mit einem Luftaustrittsspalt (112) zum Abblasen von überschüssigen Teilen des noch flüssigen Beschichtungsmaterials (310) von der Oberfläche des Metallbandes (200) nach dem Durchleiten des Metallbandes (200) durch den Beschichtungsbehälter (300) und eine oberhalb der Abblaseinrichtung (110) angeordnete elektromagnetische Stabilisierungseinrichtung (140) mit einer Mehrzahl von einzelnen Magneten (144) zur Stabilisierung des Metallbandes nach dem Verlassen des Beschichtungsbehälters (300) und der Abblaseinrichtung (1 10). Um die Effizienz der Vorrichtung noch weiter zu steigern, sieht die vorliegende Erfindung vor, dass zumindest einzelne der Magnete (144) der Stabilisierungseinrichtung (140) als Topfmagnete mit einer Topfspule ausgebildet sind.
