Abstract

L'invention concerne une chaîne de production de couche de revêtement galvanisé. La chaîne de production comprend la mise en place successive, selon un flux de travaux, d'une machine de sablage, d'une machine de fluxage, d'une première lame d'air, d'un dispositif de préchauffage, d'un bain d'immersion à chaud, d'une seconde lame d'air et d'une chambre de refroidissement. La machine de fluxage, la première lame d'air, le dispositif de préchauffage, le bain d'immersion à chaud, et la seconde lame d'air comportent chacun une voie de passage mobile à travers laquelle une pièce de travail peut passer ; et, disposés entre un appareil, se trouvent des transporteurs à rouleaux le long desquels se déplacent les pièces de travail. Parce que la machine de fluxage, la première lame d'air, le dispositif de préchauffage, le bain d'immersion à chaud et la seconde lame d'air comportent chacune une voie de passage mobile à travers laquelle une pièce de travail peut passer, les barres d'armature sont capables de reposer à plat lorsqu'elles se déplacent une par une entre l'appareil durant le processus. Ceci assure une production hautement efficace et la galvanisation de longues barres d'armature. De plus, chaque appareil dans la présente invention peut être fabriqué plus grand ou plus petit conformément aux exigences de revêtement. La chaîne de production possède une structure compacte, est hautement modularisée et est facile à la fois à agrandir et à améliorer.
