Abstract

Se resuelven los problemas causados por óxidos formados sobre una superficie de una lámina de acero que contiene Cr. Se proporcionan un método para la producción de una lámina de acero galvanizada por inmersión en caliente de alta resistencia que tiene una buena adherencia del recubrimiento y un aspecto de superficie bueno y un método para la producción de una lámina de acero recocida después de galvanizada de alta resistencia. Una lámina de acero galvanizada por inmersión en caliente de alta resistencia se produce mediante un método que incluye una primera etapa de calentamiento para mantener una lámina de acero a una temperatura específica durante un tiempo específico en una atmósfera que tiene una concentración específica de H2 y un punto de rocío específico, el lámina de acero tiene una composición específica, una etapa de enfriamiento para enfriar la lámina de acero después de la primera etapa de calentamiento, una etapa de tratamiento electrolítico para someter la lámina de acero después de la etapa de enfriamiento a tratamiento electrolítico bajo condiciones específicas, una segunda etapa de calentamiento para mantener la lámina de acero después de la etapa de tratamiento electrolítico a una temperatura específica durante un tiempo específico en una atmósfera que tiene una concentración específica de H2 y un punto de rocío específico, y una etapa de tratamiento de recubrimiento para someter la lámina de acero después de la segunda etapa de calentamiento a tratamiento de galvanización por inmersión en caliente.
