Abstract
A method for manufacturing a one-side electrogalvanized steel strip, which comprises: continuously causing a steel strip to travel through an electrogalvanizing bath in an electrogalvanizing tank; arranging an electrode plate in the electrogalvanizing bath in the electrogalvanizing tank in parallel to a one-side surface to be electrogalvanized of the steel strip; electrogalvanizing the one-side surface of the steel strip; arranging a spray nozzle toward the other surface not electrogalvanized of the steel strip which has passed through the electrogalvanizing tank; ejecting any one of an aqueous solution containing a weak acid of from 0.1 to 5.0 wt. % and a saturated monovalent alcohol having carbon atoms of up to 5 from the spray nozzle onto the other surface of the steel strip to wet the other surface of the steel strip; arranging a brush roll in close proximity to the spray nozzle on the same side as the spray nozzle; and rotating the brush roll while bringing same into contact with the other surface thus wet of the steel strip to eliminate contamination caused by the deposition of an electrogalvanizing solution on the other surface of the steel strip.
