Abstract
A method and device for removing metal fumes inside a snout in a continuous hot-dip plating plant are provided, which are capable of reliably removing metal fumes causing unplating from the snout without heating an outer wall of the snout. Heated inert gas is supplied to an inside of a snout which is formed between a continuous annealing furnace outlet and a hot-dip metal plating bath. Atmospheric temperature of the inside of the snout and temperature of an inner wall of the snout are maintained, gas having a flow rate greater than a gas supply flow rate is exhausted. A gas stream is formed which flows from the continuous annealing furnace to a surface of the hot-dip metal plating bath, which prevents quality defect from occurring caused by metal fumes generated from molten metal surface.
