electrolyte for a moment, for a moment again expose liquid level of electrolyte 7, further exacerbate the unstable of above-mentioned electric field and It is uneven so that the virtual electrode current potential at this compared with theoretical electrode potential difference away from larger, when electrorefining miscellaneous positive plate high, with Theoretical electrode potential difference causes the foreign metal in the junction compared to positive plate main body 301 away from larger virtual electrode current potential Faster, short time interior concentration becomes ion and enters electrolyte so that the junction is internally formed very for interior foreign metal dissolving Multiple hole, appearance seems connection, and in fact internal already close to hollow, with the carrying out of electrorefining processes, above-mentioned hole becomes It is more and more and increasing, when being not enough to suspend in midair the weight of positive plate main body

positive plate main body 301, because by the electrolysis of early stage and mid-term, The overwhelming majority of positive plate main body 301 now has dissolved, 301 thin plates of surplus very thin thickness of positive plate main body, and weight is very Small, the junction of the positive plate main body 301 and hanger 302 that there is hole can sustain this weight, will not be broken, and Dissolving can be re-energised to the position that the upper end of electrolysis mid-term middle-jiao yang, function of the spleen and stomach pole plate main body 301 does not occur electrodissolution in the later stage, entered And ensure that the residual anode ratio of positive plate 3 will not be raised too much because of regulation liquid level of electrolyte up and down, both avoid electrorefining The generation of board falling phenomenon is broken in miscellaneous positive plate high, the residual anode ratio relatively low, in allowed band of positive plate 3 is in
