<p>Cold rolled steel strip is treated, prior to annealing, with a dilute aqueous rinse solution containing soluble calcium salt or a soluble ferricyanide or ferrocyanide salt or a mixture of soluble calcium salt with sodium nitrite or soluble ferricyanide or soluble ferrocyanide. The residues of said rinses inhibit rust formation on the annealed strip during storage and transit.</p> |
