A continuous hot-dip metal plating method is provided with which it is possible to inhibit both non-plating attributable to metal vapor generated inside the snout and non-plating attributable to an oxide film on the molten-metal-bath surface inside the snout and to stably and rapidly change the oxidizing ability of the atmosphere inside the snout. The continuous hot-dip metal plating method according to the present invention is characterized by supplying an oxidizing gas to the inside of a snout 14, regulating the temperature of the inner wall of the snout to a temperature not lower than (plating bath temperature)-150°C, and regulating the temperature of the upper atmosphere inside the snout to a temperature not lower than (plating bath temperature)-100°C. |
