Abstract: Dual-purpose universal rolling stand, which is suitable to be equipped as a two-high rolling stand (113) and a universal rolling stand (213) and which cooperates with a standardized base plate (29) and comprises four housings (28) with outer support projections (41) and inner arms (47) including lateral position surfaces (48) and specific means to anchor main screwing-down screws (34) and also comprises standardized one-type bearing blocks (36) for the two purposes of the stand, the bearing blocks (36) cooperating with the housings (28) and the main screws (34) to form respectively two first housings/bearing blocks assemblies (30) and two second assemblies (24) of housings/bearing blocks/vertical rolling rings in which the third vertical rolling ring assemblies (25) are included, the first assemblies (30) or the second assemblies (24) being installed facing each other and reciprocally positioned by equipment holder bars (33) and (133) repectively.

Abstract: A time period between slabs entering a rolling stand which are produced by a continuous caster is controlled to enable a plant to be built with a considerable reduction of the overall size as compared to known plants of the same type. The plant optimally controls the speed of a continuous caster used with the rolling plant in conjunction with the speed of the workpiece along the passline through the rolling stands. This minimizes the length of the plant and provides both the minimum time for the slab to reach the rolling stands from the furnaces, as well as provides for the necessary time to change the rolls of the roll stand when required, while allowing continuous operation of the caster.

Abstract: Apparatus (10) to replace sets of rolls and relative equipment in rolling stands having rolls supported as cantilevers, which is able to take from the stand the sets of rolls and relative equipment complete and already used and to deliver to the stand new sets of rolls and relative equipment complete and already prepared, positioned and adjusted, the sets of rolls and relative equipment consisting of the rolls, relative equipment, supports and everything else which can be replaced whenever the rolls are changed, the apparatus (10) comprising in reciprocal cooperation a support device (15), at least one positioner assembly (20) and, at least momentarily, at least two support units (21), the positioner assembly (20) being able to move so as to place opposite and position correctly a support unit (21) in relation to the rolling stand (11).

Abstract: Universal rolling stand with horizontal rolling rings supported as cantilevers on the mill stand, to the front of which stand is fitted a universal device (13) that forms a compact unit, pre-assembled and pre-positioned, comprising horizontal rolling rings (12), means (30) to secure the horizontal rings, vertical rolling rings (23) and equipment (33) to guide the rolled stock.

Abstract: Clamping device for a rolling ring assembly(10') which has a vertical axis and comprises a rotation axle (11') fitted to a bearing block (12'), a jacket (13') secured to the rotation axle (11') and supported by an end support (19') cooperating with the axle (11') and a bearing (14') installed in cooperation with the jacket (13'), a rolling ring (21') that forms a rolling body being fitted to the bearing (14') by means of clamping means including a pair of flanges (23'), the device comprising shoulder rings (30-31) consisting of at least one metallic element capable of being inserted in circumferential grooves (28-29) which are substantially perpendicular to the rotation axle (11') and which are formed in the inner wall of the rolling ring (21'), the shoulder rings (30-31) projecting from the grooves (28-29) by a predetermined distance and cooperating with the flanges (23 ') to clamp and keep in position the rolling ring (21') against the bearing (14').

Abstract: Compensating device able to compensate the load acting on e upper bearings (13-17) of shafts of rolls (10) supported at only one end on rolling stands (18), such rolls (10) comprising shafts (11) having at least two bearings (13-14), an upper bearing (13) and a lower bearing (14), the device comprising springs (20) able to provide a resiliently yielding constraint between such bearings (13-14).
