Abstract

An apparatus for manufacturing a molten metal coated steel strip according to the present invention, the apparatus being configured to control the amount of a metal coated on surfaces of a steel strip S by blowing a gas from gas wiping nozzles 3 to the surfaces of the steel strip S continuously drawn from a molten metal 8, includes molten-metal-reducing members 1 arranged on both sides of the steel strip S below the surface of the molten metal in the coating bath 9 so as to face the steel strip S, each of the molten-metal-reducing members 1 having a length equal to or longer than the steel-strip width, and shields 2 arranged between the molten-metal-reducing members 1 each extending along an extension of a corresponding one of the surfaces of the steel strip S, the molten-metal-reducing members 1 being arranged so as to face the steel strip S. The use of the apparatus reduces an excess amount of molten metal sticking to the steel strip drawn from the molten metal across the entire width of the steel strip, thereby reducing the occurrence of splashing in the gas wiping step.
