APPARATUS AND METHOD FOR MANUFACTURING HOT DIP COATED METALLIC STRIP

摘要

PROBLEM TO BE SOLVED: To provide a apparatus and method for manufacturing a hot dip coated metallic strip making it possible to suppress the amount of molten metal lifted from a coating bath by being excessively stuck to the metallic strip pulled up from the coating bath in manufacturing the hot dip coated metallic strip. SOLUTION: The apparatus for manufacturing the hot dip coated metallic strip is provided with: a coating bath 1 for holding a hot dip metal coating bath 2; a sink roll 3 for changing the direction of the metallic strip S entering the inside of the coating bath 2; and a gas throttle device 6 for regulating the amount of the hot dip metal coating sticking to the metallic strip S. The apparatus is further provided with molten metal throttle members 5 facing both sides of the metallic strip S without coming in contact therewith between the sink roll 3 or an in-bath supporting roll 4 and the device 6. More particularly, the members 5 are preferably disposed across the top and bottom of the coating bath surface. COPYRIGHT: (C)2004,JPO
