  • Method for manufacturing molten metal plated steel strip
    Patent number: 8529998
    Abstract: A gas wiping nozzle includes a primary nozzle portion and at least one secondary nozzle portion provided either or both above and below the primary nozzle portion. The secondary nozzle portion jets a gas in a direction tilted from the direction in which the primary nozzle portion jets the gas and at a lower flow rate. The gas wiping nozzle has a tip whose lower surface forms an angle of 60° or more with the steel strip. The gas jetting port of the secondary nozzle portion is displaced in the direction opposite to the steel strip at least 5 mm apart from the gas jetting port of the primary nozzle portion, and the secondary nozzle portion jets the gas so that the flow rate of the secondary gas jet comes to 10 m/s or more at the confluence with the primary gas jet from the primary nozzle portion.
