The invention relates, among other things, to a device for avoiding surface flaws, caused by metal dust, on a metal strip to be coated in a continuous hot-dip coating process, wherein at least some segments of the metal strip to be coated can be conveyed through the device in an axial direction, comprising a blowing/sucking unit, wherein the blowing/sucking unit has a plurality of blow-in openings for applying protective gas to the metal strip, wherein a plurality of blow-in openings are or can be arranged on a first side of the metal strip and a plurality of blow-in openings are or can be arranged on a second side of the metal strip, wherein the blowing/sucking unit has a plurality of suction openings for extracting protective gas laden with metal vapor and/or metal dust, wherein a plurality of suction openings are or can be arranged on the first side of the metal strip and a plurality of suction openings are or can be arranged on the second side of the metal strip. The aim of improving the extraction of metal vapor by means of the protective gas and of reducing the dispersion of metal vapor is solved in that the blowing/sucking unit has a blow-in region, in which the blow-in openings are arranged, and a suction region, which is arranged after the blow-in region in the axial direction and in which the suction openings are arranged.

DEVICE AND METHOD FOR IMPROVED EXTRACTION OF METAL VAPOR
US15575477
[Sridhar Palepu, Michael Peters, Norbert Schaffrath, Sabine Zeizinger]
DE Duisburg
A device minimizes or eliminates surface flaws caused by metal dust on a metal strip to be coated in a continuous hot-dip coating process, where at least some segments of the metal strip to be coated are conveyed through the device in an axial direction. The device may comprise a blowing/sucking unit with blow-in openings for applying protective gas to the metal strip, which blow-in openings are positionable on first and second sides of the metal strip. The blowing/sucking unit may further include suction openings for extracting protective gas laden with metal vapor and/or metal dust, which suction openings are positionable on the first and second sides of the metal strip. The blowing/sucking unit may have a blow-in region in which the blow-in openings are arranged, and a suction region downstream of the blow-in region in which the suction openings are arranged.
