<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a spangle-fined melted aluminum-plated steel plate. <P>SOLUTION: The method of manufacturing the spangle-fined melted aluminum-plated steel plate is characterized in that: there is used a two-fluid mist nozzle in which an expanding angle of water mist is not larger than 40°, a spay water amount per nozzle is 1 to 5L/hr, an average particle diameter of the water mist is 5 to 9 μm. The water mist is sprayed by setting the nozzle so that a distance between a nozzle tip and the steel plate may be in a range of 100 to 250 mm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
