Abstract
PURPOSE: To prevent the dross involvement, and to extend the roll life, by prescribing the surface characteristics of the reducing roll for the galvanized steel sheet with the surface roughness 2.5W5.0μRa, the cutoff level 1.2W1.3μ, and PPI 150 or more.
CONSTITUTION: This roll is a temper rolling roll possessing the dull roll surface roughness 2.5W5.0μRa, the cutoff level 1.2W1.3μ, and PPI (number of peak per inch) 150 or more. If the surface roughness as the mean roughness on the center line is less than 2.5μRa, the dull profile can not be satisfactorily transferred to the galvanized steel sheet, and the roll life is shortened. Besides, if above roughness exceeds 5.0μRa, the surface roughness becomes coarse and the appearance is deteriorated. The cutoff level 1.2W1.3μ is in the range permissible to exactly count the number of peak for bringing about the effect. If the value of PPI is smaller, the sectional area of a peak becomes large, the wear of the roll surface becomes irregular, and the amount of dross involvement increases.
