GAS WIPING METHOD AND GAS WIPING DEVICE

摘要

A gas wiping device is provided with: a pair of wiping nozzles disposed facing each other so as to sandwich a plated steel plate in the direction of thickness of the plated steel plate and such that each sprays wiping gas along the direction of the width of the plated steel plate; gas shielding plates disposed so as to be sandwiched by the wiping nozzles in each of the positions away from both side end parts of the plated steel plate toward the outside; and side nozzles that spray gas so as to form a gas flow along the both sides of the respective gas shielding plates in the reverse direction of the direction in which the plated steel plate is pulled.
