    摘要： 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).

    摘要： A strip rolling mill includes a pair of upper and lower work rolls for rolling a strip, intermediate rolls for supporting each of the paired work rolls, and back-up rolls for supporting each of the intermediate rolls. Each of the work rolls is provided with a tapered portion at a vicinity to one end thereof in such a way that the tapered portions of the work rolls are on opposite sides of roll bodies thereof with respect to roll axis directions. The rolling method for the strip rolling mill comprises the steps of: when the material with a constant width is being rolled, setting axial positions of the work rolls at appropriate positions and changing axial positions of the intermediate rolls to control a thickness distribution in a width direction of the material being rolled. This arrangement significantly improves an edge drop and at the same time minimizes edge drop variations, thereby preventing surface defects from occurring on the surface of the material being rolled and performing an efficient rolling operation.

    摘要： A rolling mill stand having a pair of side shiftable rolls defining a roll gap profile therebetween varying along the length of the rolls according to a sixth order polynomial equation. The flatness of the strip exiting the rolling mill stand is controlled by determining the temperature profile of the rolls and adjusting the side shift positions of the rolls to compensate for the expansion of the rolls due to changes in the temperature of the rolls.

    摘要： In a multi-roll rolling stand having two intermediate rolls 3 to 6, which each have only one tapered roll barrel end, in each case two tapered roll barrel ends lie on each side of the rolling stand. The intermediate rolls 3, 4 and 5, 6, the two roll barrel ends of which lie on the same side of the rolling stand, are independently displaceable in an axial direction. Due to the axial offset of the tapered roll barrel ends which can be achieved in this manner, the support curve of the work rolls 1, 2 in the edge regions of the rolled strip can be finely adjusted. In addition, the support curve in the center region of the strip can also be adjusted if in each case one of the two work rolls 3, 4 associated with each work roll 1, 2 is contoured.

    摘要： A roll stand has a support frame, a pair of similar small-diameter working rolls rotatable about respective vertically spaced axes and defining a workpiece nip receiving a workpiece to be rolled, and a pair of similar large-diameter backup rolls rotatable about respective axes vertically flanking the working-roll axes and each bearing vertically on the respective working roll. These working rolls have ends and each have therebetween an effective axial length equal to at least 1.3 times the effective axial length of the respective backup rolls. Actuators are connected to the working rolls for displacing same axially relative to the backup rolls through an axial distance equal to about their own effective axial lengths between end positions each engaging only about half of the respective backup roll. A selector feeds to and through the stand a group of strips comprised generally of pairs of strips wherein the combined width of the strips of each pair is generally equal to the working-roll width. A controller is connected to the actuator for positioning the working rolls of the stand with their ends at one edge of one of the workpieces of each pair and at the opposite edge of the other workpiece of the pair.

    摘要： 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.
