Zusammenfassung:PURPOSE:To remove a bad influence (reduction of a plate width) accompanied by tension variation between stands in hot rolling by a tandem rolling mill. CONSTITUTION:At stands at least one before the last stand of a tandem type hot finishing mill, the sheet is passed by setting the shape (flatness) of the material on the outlet side of each stand to at least the shape with its tip part formed to the shape of edge wave, by which the plate width is prevented from being reduced by generation of excessive tension at the time of being bitten into the stand.
