発明の名称
(EN) Galvanized steel sheet and method for manufacturing the same
(ZH) 镀锌系钢板及其制造方法
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 to 100g/l, exposed to an aqueous solution with a pH of 6 to 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.

(ZH)

一种镀锌系钢板的制造方法,使锌离子浓度在1~100g/l范围的含锌的水溶液接触钢板表面,接着,与pH6~14的水溶液接触后,进行水洗干燥。在含锌的溶液中,例如,可以举出含有锌的硫酸盐溶液。通过以上的方法,在钢板表面形成平均厚度为10nm以上、含有锌作为主体的氧化物层,从而能够高速且稳定地节省空间地制造出具有优异的冲压成型性的镀锌系钢板。
