Abstract
A method of supplying a Zn—Al alloy to a molten zinc pot which accommodates a molten zinc bath in a hot dip galvanizing line, includes: supplying the Zn—Al alloy from a supply portion provided at a lower portion of an insertion guide having a pipe shape, in which the supply portion is immersed between an inner wall of the molten zinc pot on a downstream side in a travelling direction of a steel sheet and a front support roll installed in the molten zinc bath at a depth within ±400 mm from a lower end of the front support roll, and an inside of the insertion guide is pressurized by inert gas to prevent the molten zinc bath from advancing to the inside of the insertion guide.
