(EN) GALVANIZED STEEL SHEET AND METHOD FOR MANUFACTURING THE SAME
(FR) TÔLE D’ACIER GALVANISÉ ET SON PROCÉDÉ DE PRODUCTION
(JA) 亜鉛系めっき鋼板およびその製造方法
要約
(EN)
Provided is a method for manufacturing a galvanized steel sheet, wherein the surface of the steel sheet is exposed to an aqueous solution that contains zinc with a zinc ion concentration in the range of 1-100g/l, exposed to an aqueous solution with a pH of 6-14, and then washed and dried. An example of a zinc-containing solution would be a solution that contains zinc sulfate. The aforementioned method enables an oxide layer, mainly composed of zinc with an average thickness of no less than 10nm, to be formed on the surface of the steel sheet, thereby enabling a galvanized steel sheet with excellent press formability to be manufactured quickly, in a stable manner, and in minimal space.
(FR)
L’invention concerne un procédé de production de tôle d’acier galvanisé, dans lequel la surface de la tôle d’acier est exposée à une solution aqueuse qui contient du zinc selon une concentration en ions zinc comprise entre 1 et 100g/l, puis exposée à une solution aqueuse à pH compris entre 6 et 14, et enfin lavée et séchée. Un exemple de solution contenant du zinc est une solution qui contient du sulfate de zinc. Le procédé précité permet de former une couche d’oxyde, essentiellement composée de zinc d’épaisseur moyenne égale ou supérieure à 10nm, sur la surface de la tôle d’acier, ce qui permet de produire une tôle d’acier galvanisé présentant une excellente aptitude au formage sous presse rapide, de manière stable et dans un espace minimum.
(JA)
亜鉛系めっき鋼板の製造方法は、鋼板表面に、亜鉛イオン濃度として1~100g/lの範囲で亜鉛を含有する水溶液を接触させ、次いで、pH6~14の水溶液に接触させた後、水洗・乾燥を行う。亜鉛を含む溶液中としては、例えば、亜鉛の硫酸塩を含む溶液が挙げられる。以上の方法により、鋼板表面に、平均厚さが10nm以上であり、亜鉛を主体として含む酸化物層が形成され、優れたプレス成形性を有する亜鉛系めっき鋼板が、高速かつ安定的に省スペースで製造できる。
