Abstract

PURPOSE:To correct the shape of a rolled metallic plate to a prescribed plate shape in the stage of rolling a metallic plate hot or cold, by turning an intermediate roll provided between a work roll and a backup roll on one side in a horizontal direction. CONSTITUTION:A metallic plate work W is rolled hot or cold with a rolling mill provided with a pair of work rolls 2 and a pair of backup rolls 4 as well as an intermediate roll 6 between the rolls 2 and 4 on one side. In this case, the roll 6 is made turnable in a horizontal direction by an angle theta with a barrel center 14 as a fulcrum. It is possible to change the distributions of the forces backing up the work rolls 2 by moving the roll 6 in parallel with the rolls 2 and turning the same horizontally, and it is possible to correct the shape of the plate and the distortions in its width direction easily by changing the rate of bending of the rolls 2 and controlling the rate of bending with the extents of movement and turning of the roll 6.
