A rolling mill has a work roll (1), a back-up roll (2) for supporting the work roll (1) vertically and driving it. A plurality of horizontal support rollers (4,6) contact the work roll at barrel diameter outside the rolling region and at both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal ...

For instance, at the top levels, productivity of the rolling mill is one of many issues to be considered, while at lower levels, for example, the determination of the number of passes and the form of grooves must be obtained ([12], [13], [14]). A parameter or an objective function can also be of singular or multiple hierarchical level in nature.

Since cross-sectional area is reduced progressively at each set of rolls, the stock moves at different speeds at each stage of the mill. A rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 160 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long ...
