<p>PROBLEM TO BE SOLVED: To provide a method for producing an electrogalvanized steel sheet having high corrosion resistance.SOLUTION: A plating bath includes Zn ions of 0.2 mol/L or higher and V ions of 0.1 mol/L or higher, the relative flow velocity of the plating liquid in the plating bath to a steel sheet stock is controlled to 0.5 m/s or higher, further, divided energization is performed to the steel sheet stock for two or more times, and, in each time of the divided energization, current density is controlled to 10 A/dmor higher, and also, continuous energization electric quantity is controlled to 5,000 C/mor lower.</p> |
