Abstract

Feuille d'acier laminée à chaud non décapée qui a une noirceur suffisante comme on peut le voir à partir de chaque direction, et qui a une excellente adhérence de calamine. La feuille d'acier laminée à chaud non décapée comprend une feuille d'acier laminée à chaud de matériau de base et une calamine sur une surface de la feuille d'acier laminée à chaud de matériau de base, la calamine comprenant du Fe3O4 et du Fe et ayant une épaisseur de 3,0 à 20 µm. Dans une couche supérieure de la calamine, une taille de grain moyenne n'est pas supérieure à 3,0 µm. Dans une section transversale de la calamine, un rapport de superficie de Fe est inférieur à 1,0 % dans la région de 0 à 1,0 µm à partir d'une couche la plus haute de la calamine dans une direction d'épaisseur de la calamine, et n'est pas inférieur à 1,0 % dans la région de 0 à 1,0 µm à partir de l'interface entre la calamine et la feuille d'acier laminée à chaud de matériau de base dans la direction d'épaisseur de la calamine.
