Abstract
A sheet rolling method uses a rolling mill (10) for rolling a sheet (x). The rolling mill (10) includes upper and lower backup rolls (13, 14), and a pair of work rolls (11, 12) respectively having different diameters and disposed between the upper and the lower backup roll (13, 14). A small-diameter work roll (11) of the pair of work rolls is disposed so that a rotational axis thereof is positioned on a mill center or a downstream side with respect to the mill center in a rolling direction, and the large-diameter work roll (12) is disposed so that a rotational axis thereof is positioned on a downstream side with respect to the rotational axis of the small-diameter work roll (11) in the rolling direction. Thus, mechanical load on the work rolls (11, 12) can be reduced even when a high rolling force is necessary for rolling a wide sheet.
