Abstract
The present invention relates to a method of reducing a band mark on an electroplating steel sheet, which can also reduce plating defects and damages to the materials caused by the differences in the physical characteristics of composition materials of a conductor roll used during electroplating Zn or Ni onto a steel sheet. In other words, the present invention comprises ceramic coating portions of circular bands, placed respectively in a thin strip at the both edge regions of the metal band position at the central portion of a conductor roll. In this manner, the present invention has the effects of reducing a band mark on a plating steel sheet, and also suppressing the generation of static electricity by eliminating the level difference between the conductive material (metal band portion) and the non-conductive material (rubber section). The present invention is also cabaple extending the life of a conductor roll by enhancing the wear and corrosion resistances thereof.
