Abstract

PURPOSE: To improve coating finish appearance and press workability by subjecting the steel plate, which has undergone cold rolling and annealing, to skin pass rolling with the dull rolls in which the surface roughness (μRa) of roll and the number of crests (PPI) have been controlled to the specific conditions.
CONSTITUTION: The annealed plate which has been produced through cold rolled steel plate production process is subjected to skin pass rolling by using the dull rolls having been controlled to the undermentioned conditions. I.e., the surface roughness (μRa) of the roll and the number of crests (PPI) to PPI (cut-off level 1.20W1.30μRa) ≥290-30×(μRa). Here, the unit Ra of the roll surface roughness is the mean roughness at the centerline, the unit PPI of the number of crests is the number of crests per inch length and the cut-off level is the peak of each crest for determining the roughness having been cut to a fixed height level.
