ABSTRACT:
Metallic articles, for instance, ferrous strips are metallized, for instance, zinc coated by passing the heated article through a coating chamber and applying thereto a continuous stream of the molten coating metal so as to uniformly and evenly metallize said article. Thereafter, excess molten coating metal is removed from the coated article by hot gas blasting and the hot gas blasted article leaving the coating chamber is immediately cooled. Wiping means may be provided before applying the molten coating metal so as to deflect any molten coating metal dropping from the metallic article passing therethrough, while rollers may be arranged between the coating metal applying means and the hot gas blasting means. Said rollers serve to remove the major part of excess coating metal from the coated metallic article and to stabilize movement of the metallic article passing through the coating chamber. In contrast to known application of coating metal by atomizing or spraying, no gas is admixed to the continous stream of the molten coating metal which is, so to say, gently poured onto the surface of the metallic article. Thus coating is effected within a short period of time and a non-porous coating is achieved.
