  • Patent number: 3941906
    Abstract: The improved hot dip metallizing process of this invention comprises passing the article to be metallized, such as a ferrous metal article, through a bath of a molten heavy metal, such as lead, and conducting the article therefrom through a layer of molten coating metal, such as zinc, confined in a stack-like structure of a cross-sectional area being a small fraction of the surface area of the heavy metal bath. The molten coating metal is continuously supplied to the stack, preferably through orifices or nozzles so as to remove any droplets of molten heavy metal adhering to the surface of the article, thereby causing metallizing of the article and continuous overflow of excess molten coating metal at the top of the stack. Before hot blasting the coated metallic article it may be passed through mechanical removal means, such as counterrotating rollers to remove the major part of excess coating metal, while the remainder is removed by hot blasting.
