| description | According to the present invention, it is possible to provide a method for manufacturing a hot-dip galavanized steel sheet which has a high Si content and which has good plating adhesion. This method for manufacturing a hot-dip galavanized steel sheet includes: a step of hot rolling a steel raw material containing 1.0 mass% or more of Si and then winding the same at 500â¿¿-700â¿¿; a step of subjecting the surface of the steel sheet after the winding to an oxidation treatment at a heating temperature of no more than a steel plate temperature of 750â¿¿ and then subjecting this surface to a reduction treatment; and a step of subjecting the steel sheet after the reduction treatment to a hot-dip galvanizing treatment to form a hot-dip galvanization layer on the surface of the steel sheet.
De acuerdo con la presente invención, es posible proporcionar un método para la fabricación de una chapa de acero galvanizada en baño de zinc caliente que tenga un alto contenido de Si y una buena adhesión del placado. Un método para fabricar una chapa de acero galvanizada en baño de zinc caliente según la presente invención incluye los pasos de: laminación en caliente de una materia prima de acero con un contenido de 1.0 % en masa o más de Si y enrollado de una chapa de acero a 500 ?C a 700 °C; someter una superficie de la chapa de acero después del enrollado a un tratamiento de oxidación a una temperatura de calentamiento de una temperatura de chapa de acero de 750 ?C o menos, y posteriormente someter la superficie a un tratamiento de reducción; y someter la chapa de acero después del tratamiento de reducción a un tratamiento de galvanización en baño de zinc caliente para formar una capa de placa de Zn en la superficie de la chapa de acero. |
