Abstract (en)
[origin: EP3276037A1] Provided is a continuous hot-dip galvanizing apparatus that can inhibit roll pick-up in a soaking zone caused by condensation or the like in a humidified gas pipe, and with which favorable coating appearance can be obtained. The continuous hot-dip galvanizing apparatus includes an annealing furnace in which a heating zone, a soaking zone, and a cooling zone are arranged in this order, and a hot-dip galvanizing line adjacent to the cooling zone. Gases supplied to the soaking zone (12) are: mixed gas obtained by mixing gas that is humidified by a humidifying device (50) and gas that is not humidified by the humidifying device; and dry gas that is not humidified by the humidifying device. The continuous hot-dip galvanizing apparatus includes a draining device (80) for draining circulating water from the humidifying device (50) when the mixed gas is not supplied to the soaking zone (12).
