PROBLEM TO BE SOLVED: To provide a clogging prevention method which can surely prevent clogging caused by adhesion of molten zinc to a wiping nozzle, and to provide a clogging prevention apparatus.SOLUTION: When a welding point between a preceding steel sheet and a subsequent steel sheet passes through a wiping nozzle part of a continuous molten zinc plating line, a clogging prevention plate is inserted between the steel sheet and wiping nozzles at the same time when a baffle plate adjacently arranged along a traveling steel sheet edge is evacuated, or immediately before the evacuation, to prevent scattering of molten zinc, whereby clogging of the wiping nozzles is prevented. |
