Abstract
PURPOSE: To obtain one side zinc electroplating steel sheet having a good appearance and adhesive property of coating carried out electrodeposition painting on non- plating face, by polishing non-plating face of steel sheet after carrying out pickling and/or electroplating.
CONSTITUTION: The cold rolled sheet 1 is passed through the alkali fat removing process 4, the water washing process 5 and the pickling process 6 after passing the shear 2 and the welding machine 3. On this occasion, the polishing processes 9, 10 are provided at both or only latter after the process 6 and next zinc electroplating process 8 and one side zinc electroplating sheet is manufactured polishing non-plating face of the sheet 1. Surface reactivity of the sheet 1 lost after passing through the acid washing bath and plating bath, is recovered by polishing the non-plating face and close zinc phosphate chemically-made coating is formed. Accordingly, fresh picturing property and adhesive property of electrodeposition coating of non-plating face, are able to make good.
