Abstract: A plurality of flat metal items to be rolled (3) are fed to a plurality of rolling stands (1, 2) of a rolling installation, one after the other over a feed path (4). The items (3) are rolled by the rolling stands (1, 2) past which they are fed. In the rolling stands (1, 2), the flat item to be rolled (3) is first rough-rolled in at least one roughing pass with a wedge-type roll gap adjustment (ds) and then finish-rolled in finishing passes. After the finish-rolling of the flat item, a thickness taper (dd) that is present in the respective finish-rolled flat item is recorded by measuring instruments. The thickness taper (dd) is compared with a target taper (dZ). On the basis of a deviation of the thickness taper (dd) from the target taper (dZ) and the wedge-type roll gap adjustment (ds), a new wedge-type roll gap adjustment (ds) is determined for the at least one roughing pass.

Abstract: Provided is a forging method capable of preventing a vibration state from being disturbed during forming. The present invention relates to a forging method in which, when a forging material W1 in a forming hole 12 of a die body 11 is plastically worked by driving a punch 2 into a forming hole 12 of the die body, ultrasonic vibrations are applied to the die body 11. The contact state of the forging material W1 with respect to a forming hole inner peripheral surface during the plastic working of the forging material W1 is classified into an insufficient contact state, a sufficient contact state, and a full contact state in order from the forming start time. An application of ultrasonic vibrations is started after shifting from the insufficient contact state to the sufficient contact state.
