Abstract

PURPOSE:To prevent the degradation in the quality of plated surfaces owing to the splashes of hot dipping metal by providing suction ports to one end part of gas wiping nozzles for blowing of the excess plating metal in a continuous hot dipping device for steel strips. CONSTITUTION:Gases are blown through gas wiping nozzles 3, 3' onto both surfaces of a steel strip 2 stuck with hot dipping metal on both surfaces coming out from a metal hot dipping cell, whereby the excess hot dipping metal stuck on both surfaces of the strip 2 is blown off. In this case, the one end part of the slip 13 of each nozzle is formed to such a shape as to approach gradually to the strip 2, whereby the edge parts where the excess plating metal sticks much are strongly wiped with the gases and part of the gases injected from the opposite gas wiping nozzles are sucked with gas suction slits 14 opening into another chamber. The splashes of the hot dipping metal occuring in the turbulent flow of the gases in the edge parts are eliminated and the degradation in the quality of the plated surfaces by the splashes is eliminated.
