Abstract

A continuous hot-dip plating equipment comprising first constituent metal supply means (14a-14c) for supplying of zinc (101) to aerial pot (11); second constituent metal supply means (15a-15c) for supplying of aluminum (102) to the aerial pot (11); analyzer (18) for measuring of the concentrations of constituent metals in molten metal (100) within the aerial pot (11); and control unit (19) for controlling of the first and second constituent metal supply means (14a-14c,15a-15c) on the basis of information from the analyzer (18) so as to realize such a concentration of aluminum (102) in the molten metal (100) within the aerial pot (11) that the concentration of aluminum in a coating layer formed on the surface of band plate (1) becomes a target value, the above concentration of aluminum (102) determined from predetermined correlationship, thereby accomplishing regulation of the amount of zinc (101) and aluminum (102) supplied into the aerial pot (11).
