Abstract

La présente invention concerne les dispositifs pour souffler un fluide gazeux sur une surface plane Sp, Le dispositif selon l'invention comporte un caisson 10 de fluide gazeux sous pression, avec au moins une portion de face avant plane 13, un tube creux 20 défini entre deux extrémités proximale 21 et distale 22, une ouverture d'entrée 23 située à l'extrémité 21 définissant un axe d'ouverture 24, une ouverture de sortie 25 située à l'extrémité 22 définissant un axe d'ouverture 26, le tube creux 20 présentant une courbure de façon que les deux axes 24, 26 fassent entre eux un angle a non nul, et des moyens 30 pour fixer l'extrémité proximale 21 à la portion de face plane 13 agencés de façon que l'axe d'ouverture d'entrée 24 soit sensiblement perpendiculaire à la portion de face plane. Application notamment au chauffage/refroidissement de bandes métalliques dans les fours de recuit et de revêtement.The present invention relates to devices for blowing a gaseous fluid on a flat surface Sp, The device according to the invention comprises a box 10 of gaseous fluid under pressure, with at least a portion of planar front face 13, a hollow tube 20 defined between two proximal 21 and distal 22 ends, an inlet opening 23 located at the end 21 defining an opening axis 24, an outlet opening 25 located at the end 22 defining an opening axis 26, the hollow tube 20 having a curvature so that the two axes 24, 26 form a non-zero angle between them, and means 30 for fixing the proximal end 21 to the flat face portion 13 arranged so that the opening axis inlet 24 is substantially perpendicular to the flat face portion. Application in particular to the heating / cooling of metal strips in annealing and coating furnaces.
