Filed: 1985-02-14
Abstract: PURPOSE:To prevent the plating defect of a strip owing to the foreign matter such as floating dross in a snout and to improve the quality and productivity of a plated steel plate by discharging molten zinc toward the transverse direction of the strip thereby removing adequately said foreign matter. CONSTITUTION:A discharge port 6 of a supply pipe 5 for the molten zinc in a plating bath 3 is disposed on one end side in the transverse direction within the snout 4 and the molten zinc is discharged from the port 6 toward the transverse direction of the strip 2 to generate the flow of the molten zinc along the transverse direction of the strip 2.
