Abstract

PURPOSE:To produce a terne electroplated steel sheet having glossiness and excellent in resistance to scratching by skin pass-rolling a terne electroplated steel sheet under light pressure. CONSTITUTION:A steel sheet 2 plated (Pb-Sn plating) by terne plating equipment 1 is rolled by a skin pass rolling machine 3 under light pressure at about 0.5-1% draft. Consequently, the surface of the plating film is smoothed, an extremely glossy surface is obtained, scratches are made inconspicuous, and a terne electroplated steel sheet with the scratching resistance improved is obtained.

Turn-plated steel sheet (Pb
The plated surface of the -5N plated steel sheet is matte and has a disadvantage in that its appearance is inferior to that of hot-dip plated products.

In addition, since the Pb-5n alloy plating film is extremely soft, it is easily scratched, and if it is scratched like this,
Since the uneven portion is shiny, it is very noticeable and spoils the appearance. Such scratches occur not only during the manufacturing stage but also during the processing stage, and significantly reduce the commercial value of the plated steel sheet.

By carrying out skin pass rolling under such light reduction, the surface of the plating film is smoothed, resulting in a very glossy plating surface. Furthermore, since gloss is imparted in this manner, scratches become less noticeable and the abrasion resistance is improved.
