Abstract

Procédé de réglage de l'épaisseur d'un revêtement métallique (1) déposé par immersion sur un produit tel qu'une bande ou un fil d'acier consistant à créer un courant gazeux (5) dirigé vers le bain de métal de revêtement (2) et de direction sensiblement parallèle à la direction du mouvement du produit revêtu, à faire circuler le produit à contre-courant dans ce courant gazeux et à ajuster le débit du courant gazeux, de façon à régler l'épaisseur du dit revêtement. Le courant gazeux traverse une tuyère de Venturi; il résulte de l'insufflation d'un flux gazeux (6) sous pression immédiate­ ment avant le col de la tuyère et transversalement à celle-ci.
