Abstract

L'invention appartient au domaine de la métallurgie ferreuse et notamment du laminage et peut s'utiliser dans la fabrication d'une feuille mince Fe-Zn destinée à l'industrie automobile, à la fabrication d'articles ménagers et à l'industrie du bâtiment. L'invention comprend le laminage à froid, le nettoyage chimique, le réchauffement préliminaire, le recuit de recristallisation dans un four de circulation, le refroidissement, le plaquage de zinc à chaud, le refroidissement et le redressement, ce dernier stade étant précédé d'un recuit de recristallisation à thermodiffusion de la bande à 600-720 °C dans une atmosphère d'hydrogène pendant une durée permettant la réduction de la teneur en hydrogène à une valeur inférieure à 0,002 %, ainsi que la formation d'un revêtement de fer / de zinc avec une teneur en fer de 40 à 60 % et la diffusion du zinc vers l'intérieur de la base en acier à 8 - 35 micromètres, avec formation d'un ferrite de zinc dans la couche subsurfacique. L'utilisation du procédé de l'invention permet de réduire les coûts (les frais) de fabrication d'une bande d'acier avec un revêtement de Fe-Zn de 20 à 30 % en comparaison à un acier IF avec un revêtement de Fe-Zn et d'augmenter l'adhérence du revêtement de fer / zinc à la base ainsi que sa résistance à l'usure, sa capacité de être soudé, sa capacité d'accepter la peinture, sa résistance à la corrosion; elle permet en outre d'éliminer des défauts de revêtement tels que la formation de poudres ou la formation de cratères.
