Abstract

Para obtener una chapa de acero galvanizado por inmersión en caliente de alta resistencia que tiene excelente apariencia superficial aún en el caso donde una tira de acero que contiene Mn a una relación predeterminada o más a Si se somete a tratamiento de galvanización por inmersión en caliente, un método para producir una chapa de acero galvanizado por inmersión en caliente utilizando un aparato de galvanización por inmersión en caliente continua comprende: someter una tira de acero a recocido, llevando ésta en un horno de recocido; y someter la tira de acero descargada de una zona de enfriamiento a galvanización por inmersión en caliente utilizando una línea de galvanización por inmersión en caliente, para obtener una chapa de acero galvanizado por inmersión en caliente. La tira de acero tiene una composición química que contiene, en % en masa, Mn: 1.7% o más y 3.5% o menos y Si: 0.2% o más y 1.05% o menos y satisfaciendo [Si]/[Mn] = 0.30. La composición química, un punto de rocío de una atmósfera en la zona de remojo y una temperatura de salida de la zona de calentamiento satisfacen la Fórmula (1).
