Abstract
There are provided a rolling machine and a rolling method in which the strip crown and shape control capability for a narrow-width strip is improved, so that the adequate strip crown and shape control capability for strips of various widths from a narrow width to a larger width can be secured. In the rolling machine, a pair of upper and lower working rolls are supported respectively by a pair of upper and lower intermediate rolls, and the intermediate rolls are supported respectively by a pair of upper and lower reinforcing rolls. The reinforcing rolls have an effective barrel length which is smaller than an effective barrel length of the working rolls and the intermediate rolls, and is larger than a width of a minimum-width strip to be rolled. The intermediate rolls are arranged in such a manner that their axes, disposed respectively in substantially horizontal planes, cross each other, and are crossed relative to the working rolls and the reinforcing rolls. The maximum cross angle of the intermediate rolls are increased and decreased in accordance with the width of the strip.
