Title:
METHOD FOR MANUFACTURING PLATED STEEL HAVING EXCELLENT PROCESSABILITY AND CORROSION RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2023/210909
Kind Code:
A1
Abstract:
A method for manufacturing a plated steel having excellent processability and corrosion resistance according to one embodiment of the present invention comprises: a step for immersing an iron substrate in a molten alloy plating bath; and a step for forming a molten alloy plating layer on the iron substrate by withdrawing the immersed iron substrate from the molten alloy plating bath and performing a cooling process, wherein in the cooling process, a first average cooling rate varies depending on the difference between a first temperature, which is the temperature of the molten alloy plating bath, and a second temperature, which is the solidification initiation temperature of MgZn2 phases constituting the molten alloy plating layer.
