Abstract

PURPOSE:To make it possible to carry out partial melt plating with high quality by a method wherein, in case of forming a coating for preventing plating on a surface of a steel strip not requring plating and immersing said steel strip in a molten metal plating bath to plate said steel strip, a free carbon plating prevention coating is used to prevent said steel strip from being contacted with dross and detached carbon in said bath. CONSTITUTION:An impurity removing duct 2 is provided in a plating bath tank 1 and a propeller 3 is immersed. When said propeller is rotated, a surface of a metal bath is raised and impurities are floated to a bath surface and overflowed and discharged automatically from an impurity removing port 5 of a snout 4. Therefore, the impurities are not contacted with a steel strip 9.
