<P>PROBLEM TO BE SOLVED: To attain a current efficiency of 90% or more by appropriately designing the structure of a tank corresponding to the scale of pickling equipment. <P>SOLUTION: A stainless steel strip after annealed is descaled in a neutral salt solution or an acidic aqueous solution by anode electrolyte using indirect energizing method. In such descaling equipment (electrolytic pickling equipment), the electrolytic pickling method satisfies the following formula: L >0.6 DW/I, wherein a distance between anode and cathode is L (mm), current energizing among electrodes is I(A), a substantial width of a pickling tank between the anode and cathode is W (mm), a substantial depth thereof is D (mm), and the substantial width W and substantial depth D are dimensions after the size of insulation substance is subtracted from the actual sizes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
