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.
