Beschreibung
Zusammenfassung:	A galvanizing apparatus capable of uniformizing quality of a plated strip by uniformly maintaining temperature of a strip, and a galvanizing apparatus capable of preventing condensation of zinc vapor are provided. A galvanizing apparatus comprises: a heat treatment furnace(120) in which a strip(10) is heat-treated to a temperature suitable for galvanizing operation; a plating bath(140) containing a galvanizing solution for plating the surface of the strip heat-treated in the heat treatment furnace; a snout(130) for guiding the strip from the heat treatment furnace to the plating bath; and a heating member(160) installed at the snout to heat the strip moved to the plating bath through the snout and uniformly maintain temperature of the strip. The heating member comprises heater modules(162) installed in such a way that the heater modules cover an outer peripheral surface of the snout, and a temperature control part(164) for controlling temperatures of the heater modules individually.
