Title:
電気亜鉛めっき鋼板および電気亜鉛めっき鋼板の製造方法
Document Type and Number:
Japanese Patent JP7298572
Kind Code:
B2
Abstract:
To provide an electrogalvanized steel sheet having good surface appearance in both the front surface and the rear surface by remarkably reducing metal glossiness formed by conductor roll reduction to make the glossiness difference between the front surface and the rear surface minimum, and a method for producing the electrogalvanized steel sheet.SOLUTION: A surface of the electrogalvanized steel sheet in contact at least with a conduction roll upon electrogalvanizing is jetted with a liquid obtained by mixing microparticles having the average particle diameter of 6 to 150 μm and the average circularity of 0.90 or lower.SELECTED DRAWING: None
