Abstract: The invention relates to a method for the forming of a workpiece, in particular a blank, composed of sheet steel, in which method the following steps are performed in succession: providing a workpiece composed of multiple steel layers which have been non-detachably connected to one another by roll-bonding and of which at least two steel layers have a different strength and/or elongation at fracture, heating the workpiece, and subjecting the workpiece to hot forming. To ensure a high strength and at the same time the easiest possible formability, the invention proposes that at least one section of the hot-formed workpiece is hardened, and that the workpiece is subsequently subjected to cold forming in the region in which the hardening has been performed. The invention also relates to a corresponding workpiece.

Abstract: The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for at least one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.

Abstract: An outer rim molded material is molded by forging or casting, a portion of the outer rim which extends from a hump to a bead seat is separated from part of a rim flange precursor and is caused to fall in a sloping fashion inwards of a wheel width so as to form a bead seat precursor, and the bead seat precursor so formed is then joined to be welded to a top or side of a rim well rising portion precursor. An external surface is cut to be finished to a proper shape, and an annular hollow portion is formed underneath a lower surface of the bead seat portion.

Abstract: An outer rim molded material is molded by forging or casting, a portion of the outer rim which extends from a hump to a bead seat is separated from part of a rim flange precursor 2a and is caused to fall in a sloping fashion inwards of a wheel width so as to form a bead seat precursor 12a, and the bead seat precursor 12a so formed is then joined to be welded to a top or side of a rim well rising portion precursor 5b. An external surface is cut to be finished to a proper shape, and an annular hollow portion 8 is formed underneath a lower surface of the bead seat portion.
