摘要： A rolling mill comprising at least two work rolls supported by chocks (4, 40) mounted so as to slide, with clearance, between two fixed guide faces (13a, 13b). Each chock (4, 40) is thrust laterally against the guide faces (13a, 13b) in order to take up the clearance when in service. Each chock (4, 40) is surrounded by two intermediate pieces (6a, 6b) mounted so as to slide without clearance along the corresponding guide faces (13a, 13b). These intermediate pieces are rigidly locked vertically with the chock (4) so as to move with it. Lateral thrustors (7) are interposed between at least one side of each chock (4) and the facing intermediate piece (6b) in order to push the chock back against the other intermediate piece (6a) and corresponding guide face (13a). The two guide faces (13a, 13'a) against which the two chocks (4, 4') of a roll (2) are pressed define a reference plane (P1) for the positioning of the axis of the roll (2) with the possibility of sliding parallel to that plane (P1).

摘要： The bending and balancing mechanism for axially shiftable rolls of a roll stand, especially the working rolls of a four-high roll stand, comprises a guiding block rigidly mounted in a stand window of each roll stand and roll supporting members supported horizontally slidable adjacent both ends of the rolls on an upper and/or lower lifting housing guided vertically on the guiding block. The roll bending forces are transmittable from bending cylinders to the roll supporting members and at least one bending cylinder, advantageously hydraulic cylinder, engages on the upper and lower lifting housing, this bending cylinder being supported on a stationary guiding block. Because of this latter structure the bending and balancing forces are better transmitted to the working or other rolls.

摘要： A rolling mill with axially movable rolls, comprising a supporting frame (4), at least two working rolls (1, 1') and at least two back-up rolls (2, 2'), at least one of the working rolls (1) being associated with means (42) for moving the roll (1) along its axis (10) and, for each chock (3), with two symmetrical sets of at least two bending jacks (6, 66). The offset of the roll (1) in relation to a centering position is measured continuously, and the pressure exerted by each bending jack (6) is adjusted at each moment as a function of the offset measured and of the position at the same moment of the particular jack (6) in relation to the mid-plane (P5) of a bearing (12), such that the resultant of the bending forces exerted by all the jacks (6, 66) remains directed at each moment in the mid-plane (P5) of the bearing (12), the bending jacks bearing on the chocks by sliding faces.
