Abstract (en)
[origin: EP3205741A1] To provide a continuous hot-dip metal coating method that uses a gas wiping nozzle to control the coating weight and prevents occurrence of coating surface defects so that high-quality hot-dip metal-coated steel strips can be stably manufactured at a low cost. A galvanized steel strip and a continuous hot-dip metal coating facility are also provided. A continuous hot-dip metal coating method includes continuously immersing a steel strip into a molten metal bath and blowing gas from a gas wiping nozzle onto the steel strip immediately after the steel strip is withdrawn from the molten metal bath so as to control a coating weight, in which a temperature T of wiping gas to be injected from the gas wiping nozzle is controlled on a basis of a D/B value, which is a ratio of a distance D between a tip of the gas wiping nozzle and the steel strip to a gap B of the gas wiping nozzle.
