Abstract
PURPOSE: To prevent the generation of a gold-dust flaw, and to make a dividing process and a grinding process unnecessary, by employing a roll having a limited surface roughness prescribed with an upper limit and a lower limit of Hmax for rolling a blank material having a ≤30μ surface roughness as Hmax.
CONSTITUTION: For the purpose of reducing the roll marks in the surface of a rolled sheet to ≤6μ as Hmax, a roll having a surface roughness ≥0.5μ and ≤6μ as Hmax is employed in a cold rolling pass except its final pass, for reducing a blank material having a ≤30μ surface roughness as Hmax. Then, a roll having ≤6μ surface roughness as Hmax is employed in the final pass for reducing a sheet finished to a ≥0.5μ surface roughness as Hmax just before the final pass. Accordingly, even if the surface roughness of the roll to work in the final pass is made ≤0.5μ as Hmax, the sheet surface can retain the lubricant oil, so that the heat scratches do not generate in the sheet surface.
