Abstract
Disclosed is a method of producing a hot-dip metal coated steel strip capable of sufficiently suppressing generation of bath wrinkles and producing high-quality hot-dip metal coated steel strip at low cost. The disclosed method of producing a hot-dip metal coated steel strip includes: blowing a gas from a pair of gas wiping nozzlesA andB to a steel strip S while being pulled up from a molten metal bathso as to adjust a coating weight of molten metal on both sides of the steel strip S, in which each of the gas wiping nozzlesA andB includes an injection port portion that is installed downward with respect to a horizontal plane such that an angle formed by the injection port portion and the horizontal plane is 10° or more and 75° or less, and has a header pressure below 30 kPa.
