步骤，以确保变得均匀增加比所述镀覆层的表面粗糙度，浸泡钢板的热浸镀浴中，以制备表面处理钢板，其特征在于所述涂覆的钢带移动到上部分从所述热浸渍浴撤出，并在钢板的镀覆钢带表面的上运动过程电镀步骤 调整意图金涂层重量，在步骤涂覆重量时，表皮光轧，以赋予在表皮光的表面粗糙度轧制，冷却的表面处理钢板，以及冷却所述涂覆的钢带的步骤，以冷却控制镀层钢板的镀层 前的镀覆钢板完全冷却，以提供一个热浸镀方法，包括初步的表皮光轧用于施加预皮肤通轧制步骤的镀覆层。

Increase than the surface roughness of the plating layer to be uniform, the method comprising soaking the steel sheet in the hot dip coating bath to prepare a coated steel sheet was drawn out of the coated steel strip in a hot dipping bath comprising: moving the upper portion, the coated steel strip in the upper movement process of the coated steel strip adjusting the coating weight of the surface, comprising the steps of coating weight to cool the plating layer of the controlled-plated steel sheet, and skin pass rolling, the cooled coated steel skin pass rolling to impart a surface roughness, and a step of cooling the coated steel strip the plating layer of the plated steel sheet to provide a hot dip coating method including a preliminary skin pass rolling step for applying a pre-skin pass rolled before it is completely cooled in.
