PROBLEM TO BE SOLVED: To provide a manufacturing apparatus capable of manufacturing a hot-dip galvanized steel sheet having less surface defects, and having less restrictions on equipment arrangement.SOLUTION: An apparatus 100 for manufacturing a hot-dip galvanized steel sheet comprises a container 10 for storing molten zinc, a snout 14, a sink roll 16, a support roll 18 and a current plate 20. In the current plate 20, one surface 22 faces a steel sheet P1 between the snout and the sink roll above the sink roll and in a molten zinc bath 12, and the other surface 24 is positioned so as to face a steel sheet P2 after passing the sink roll. The current plate has a shape in which the shortest distance between the one surface 22 and the steel sheet P1 facing the one surface is gradually increased in the horizontal direction toward both end portions from a central portion of the one surface.SELECTED DRAWING: Figure 1 |
