Abstract

PURPOSE:To form thin thickness plating layers at high speeds on strip surfaces at the time of applying metal hot dipping on said surfaces at high speeds, by providing the heating air zone of a temperature higher than that of hot dipping metal between the molten metal bath surface and excess plating metal blowing-off nozzles. CONSTITUTION:The strip 2 to be plated is passed in a metal bath 8 of molten zinc or the like and is pulled upward. The excess molten zinc stuck on the strip 2 is removed by the gas injected from excess plating metal blowing-off gas injection nozzles 4, 5. In this case, ceramic radiation burners 11, 12 are disposed between the surface 9 of the molten zinc bath 8 and the above-mentioned nozzles 4, 5, to form heating air zoines 10. The temperature of the heating air zones 10 is held higher than the temperature of the molten zinc for plating, whereby the fluidity of the excess molten zinc stuck on the strip 2 is made higher and is flowed down rapidly from the surface of the strip 2, thus the thin zinc hot dipped strip may be produced at high speeds.
