Abstract: An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions <1%. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 ?m to the surface of the sheet at low roll force.

Abstract: A rolling mill stand for the production of rolled strip or sheet metal includes working rolls which are supported on respective supporting rolls or on intermediate rolls which are supported on supporting rolls. At least one of the rolls having a barrel contour which runs over the entire effective barrel length and can be described by a non-linear function. The barrel contour of this at least one roll having chamfers in at least one of the marginal regions of its longitudinal extent and the chamfers forming a corrected barrel contour in these marginal regions, so that inhomogeneities in the load distribution along the contact line of two adjacent rolls, and in particular in the region of the edges of the strip, are minimized.

Abstract: A flexible forming device for forming three-dimensional shaped workpieces, comprising a frame, at least two working rollers, one or more working roller driving mechanisms and one or more adjusting mechanisms, wherein the working rollers, the one or more working roller driving mechanisms and the one or more adjusting mechanisms are installed on the frame respectively. At least one of the working rollers is a flexible working roller, which is bendable and adjustable. The forming device need not use mold and can realize the continuous formation of a three-dimensional curved surface of a plate-shaped workpiece, and the gradual formation of a tube-shaped or bar-shaped three-dimensional shaped workpiece. The forming device can save manpower, material and time.

Abstract: The invention relates to the design of multiple piece rolls, in particular backup rolls, for the use in metal rolling. The roll comprises a main part with a center bore for the removal of center defects or flaws arising from the manufacturing process, e.g., from casing or forging and at least an end part, whereas the end part has no center bore or a center bore with a diameter smaller than the bore diameter of the main part.

Abstract: Disclosed is a support roll (1) for a rolling mill, such as a plate rolling mill, flat rolling mill, or similar, comprising a jacket (2) and a roll shaft (3) which is embodied in several parts. The invention also relates to a method for producing a support roll (1).

Abstract: In the case of a rolling stand for producing rolled strip, which is provided with rolls which are axially displaceable with respect to one another, have a curved contour running over the entire effective barrel length and complement one another exclusively in a specific relative axial position of the rolls in the unloaded state, it is intended for the thickness profile of the roll gap over the active roll barrel length to be varied by axial displacement of the rolls provided with a roll barrel contour in relation to one another in such a way that a strip that is planar and free from undulations is obtained. This takes place by the profile of the barrel contour of the rolls of a pair of rolls being formed by a trigonometric function and the roll gap contour also being formed by a trigonometric function in dependence on the profile of the barrel contour and the position of the rolls within the axial displacement region.

Abstract: The invention relates to an apparatus for rolling a metallic product comprising a mill frame (18), a first cantilever roll shaft (19), a second cantilever roll shaft (20), both said roll shafts (19, 20) being mounted on the mill frame (18) with two sets of bearing assemblies (38, 39, 40, 41), a first rolling ring (21) mounted on the first roll shaft (19), a second rolling ring (22) mounted on the second roll shaft (20) said rolling rings (21, 22) forming a nip (23) in between, at least one ring (29) arranged with its inside surface (43) in rolling contact with the first roll shaft (19) and with at least one intermediate roll (27), which intermediate roll (27) is arranged also in rolling contact with the second roll shaft (20) and at least one drive end (42) arranged at the end of either roll shafts (19, 20) for driving the mill (16). The invention also relates to a method of producing a metallic product.

Abstract: A method for the strip-edge-oriented shifting of the intermediate rolls (11, 11?) in a six-roll rolling mill comprising respectively a pair of workrolls (10, 10?), intermediate rolls (11, 11?) and backup rolls (12, 12?), whereby at least the intermediate rolls (11, 11?) and workrolls (10, 10?) have devices for axial shifting cooperating with them and each intermediate roll (11, 11?) has a barrel elongated by the amount of the CVC-shifting stroke and a one sided setback (x) in the region of the strip edge. The method is characterized in that the upper intermediate roll (11) is shifted in the direction of the drive side AS) and the lower intermediate roll (11?) is shifted in the direction of the service side (BS)—or conversely—relative to the neutral shift position (Szw=0 mm) symmetrically to the rolling mill center (y—y) be respectively the same amount in the direction of their (x—x).

Abstract: A plate rolling mill includes a pair of work rolls that hold and press down a plate material therebetween, a plurality of backup rolls that prevent the work rolls from being deformed, and intermediate rolls each of which is disposed between the work roll and the backup roll so as to be shiftable. Each of the intermediate rolls has a contact roll portion that contacts with the backup roll, and an extension barrel portion that is connected to an end of the contact roll portion and does not contact the backup roll at any shifted position. The contact roll is formed to have a convex shape such that a convex center of the contact roll is positioned at a side of the extension barrel portion.

Abstract: The invention relates to an apparatus for rolling a strip (21) comprising a first work roll (24), which is mounted from both ends with bearings (35) to the mill frame, a second work roll (25), which work rolls (24, 25) are forming a nip (26) in between them, one or more ring(s) (19, 20) closing inside at least one of the work rolls (24, 25), at least first intermediate roll (27, 39) mounted to the mill frame from both ends with bearings (36) and arranged in rolling contact between the second work roll (25) and inside surface (22) of the ring(s) (19, 20). The invention also relates to the method of producing a thin strip.

Abstract: An apparatus for manufacturing a band plate has a rolling mill that includes a pair of upper and lower work rolls that roll a slab material having edge drop portions at both ends thereof, and a pair of backup rolls that contact non-rolling side surfaces of the pair of upper and lower work rolls, respectively to prevent the work rolls from being deformed. The work roll includes a reverse taper portion where a roll diameter gradually increases towards a barrel end portion thereof corresponding to the edge drop portion. The upper and lower work rolls are configured to be shiftable individually in the axial direction thereof. The backup roll includes an escape portion whose diameter gradually decreases towards an axial end thereof so as not to contact the reverse taper portion of the work roll, within a shifting range of the work roll.

Abstract: A roll for a roll stand including a roll shaft with at least one roll ring mounted on the roll shaft, wherein the roll shaft is axially displaceable. The roll stand for rolling a metal strip may be, for example, a two-high stand, a four-high stand or six-high stand. The surfaces of at least two of the inner roll components enclosed by an outer roll ring have contours which are curved in the axial direction, wherein the curved contours are turned relative to each other by 180°.
