Abstract

PROBLEM TO BE SOLVED: To produce a thin steel sheet with good surface quality using the large diameter roll in high-speed and high-efficiency. SOLUTION: A roll profile is formed by conducting a circumferential direction polishing on the surface of the roll 3, and circumferential direction polishing grain 4 is given at circumferential direction average roughness of within Ra1=0.2-0.5 μm and afterwards an axial polishing grain 5 is given at axial average roughness within Ra2=Ra1×20-100% by axial polishing. On this occasion, if Ra1 is 0.2 μm or less the roughness of the roll is small and as a friction coefficient between the roll and the sheet lowers, a slip easily arises in the rolling. On the other hand, if Ra1 exceeds 0.5 μm, the slip flaws of the product after rolling by the polishing grain in the circumferential direction becomes noticeable. And if Ra2 is Ra1×20% or less, discharge effect of the filling oil is not sufficiently obtained, and on the other hand, if Ra2 exceeds Ra1×100% the circumferential direction polishing grain 4 does not remain on the surface of the roll 3.
