    • PURPOSE: An alloyed steel plate coated a melted zinc and its production method are provided to simplify a plating process and to improve the processing property of phosphate, an electro coating property, and the corrosion by plating a upper layer of the flash coated steel plate with a vacuum depositing method and by applying a Mn metal as the upper coated group. CONSTITUTION: Mn of a upper layer is needed at least sticking amount because the Mn is converted to a film of phosphate at a processing of the phosphate. In using for a coating growth, the productivity is reduced and a cost of material is increased according to an increase of stuck amount because the unnecessary corrosion is contained when the stuck amount of Mn is over 30g/m2. Therefore, the stuck amount of Mn is desirable within 3-30g/m2. A layer coated the Mn having a fine adhesive property is formed at a temperature of an alloyed steel plate coated a melted zinc as a material over 50°C. When the temperature of the material is over 350°C, the alloyed layer coated the melted zinc is evaporated on a surface of the material. Therefore, the temperature of the alloyed steel plate coated the melted zinc is desirable at 50-350°C.
    • 目的:涂覆熔融锌的合金钢板及其制造方法,以简化电镀工艺,提高磷酸盐的加工性能,电镀涂层性能,以及通过镀上闪光涂层钢板上层的腐蚀 真空沉积方法和通过施加Mn金属作为上涂层组。 构成:由于在磷酸盐的加工中将Mn转化为磷酸盐膜,所以至少需要上限量的Mn需要Mn。 在用于涂层生长时,当Mn的粘附量超过30g / m 2时,由于含有不必要的腐蚀,所以随着粘附量的增加,生产率降低,材料成本增加。 因此,在3-30g / m 2范围内期望Mn的粘附量。 在熔融锌作为材料的合金钢板的温度下,在50℃以上的温度下形成涂覆有具有良好粘合性的Mn的层。 当材料的温度超过350℃时,涂覆熔融的锌的合金层在材料的表面上被蒸发。 因此,在50-350℃下,涂覆熔融锌的合金钢板的温度是理想的。
