Abstract
A method and apparatus for rolling a strip by a rolling mill wherein one back-up roll of the pair of back-up rolls is a variable crown roll having a single oil chamber and the other back-up roll is a variable crown roll having a plurality of oil chambers. The strip shape is detected by a shape meter and approximated by a power function which includes terms of the first, second, fourth, and sixth powers of a distance measured from the center in the width direction and then precisely controlled by a calculation and control unit based on the obtained power function.
