Abstract
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).
