Abstract: A cassette intended to be provided on a rolling mill, the cassette (1) forming a self-supporting unit including: a roller intended to constitute one of the two intermediate rollers of the rolling mill; two chocks (3) whereon are mounted the ends of the roller (2); at least one support arm (4) of the at least one side bearing member the support arm extending between the two chocks and being mounted pivotingly in relation thereto. The cassette includes at least one pair of support elements (5) receiving the ends of a rotating shaft (6) of the at least one support arm and the two support elements being detachably fastened, respectively, on the two chocks so as to allow the disassembly of the at least one support arm of the chocks and/or the assembly of the at least one support arm on the chocks independently of the disassembly/assembly of the roller.

Abstract: A method for changing the configuration of a rolling mill of the six-high type in which the rolling mill is changed from a first configuration (C1) of a range of diameters of working cylinders (3?, 4?), keeping the chocks (E1, E2) by turning over the chocks (E2) of the intermediate cylinders (5, 6) and by turning over the chocks (E1) of the working cylinders. A rolling mill as such, suitable for implementing the method is also described.

Abstract: Rolling mill (1) includes: side bearing rollers (5), able to laterally support the working rollers (2) of the rolling mill, with each side bearing roller being carried by a support arm (6), mounted pivoting on an axis (7), load distribution beams (8) extending between the corresponding posts of each pair, and elements (9) for applying a preload force on each support arm (6), intended to engage with one of the support arms on a bearing surface (10), and including at least one preload cylinder (11) integral with one of the load distribution beams (8), one or several spraying nozzles for a lubricant/cooling fluid, at least one of the nozzles (12, 12?), is embedded on one of the support arms (6) and the fluid supply circuit of the at least one nozzle (12, 12?) includes a connection/disconnection device (13) with the support arm (6).

Abstract: A rolling mill (100) includes: —a rolling-mill cage (10) containing a plurality of cylinders, including two working cylinders (12) and two pairs of intermediate cylinders (13), —a main gate (30) on the front face of the rolling mill (100) for accessing all the cylinders, —a device (20) for the lateral movement of the intermediate cylinders (13) of the push-push type including first and second pairs of hydraulic actuators (22, 22?, 21, 21?) each configured so as to exert a thrust force (P) to allow a lateral movement of the intermediate cylinders (13), —a removable small gate (40) fixed to the main gate (30), allowing access to the cylinders (12) and (13), and integrating the second pair of hydraulic actuators (21, 21?) so that opening and closing the small gate (40) does not interfere with the opening and closing of the main gate (30).

Abstract: A shearing device for fragmenting a metal strip includes two counter-rotating drums facing one another, a drive device connecting the drums and synchronising their rotation speed, and at least one pair of drum-supported blades. The blades engage by shearing effect during drum rotation to cut the waste. The blades of the pair have, from the cutting edge thereof, planar surfaces, referred to as overlapping surfaces, overlapping and facing one another during the shearing between blades, each blade being secured transversely to the drum, at an angle to the axis of rotation of the drum, so the plane through the overlapping surface of the blade forms an angle with the axis of rotation of the corresponding drum, producing gradual shearing. The overlapping surface of each blade is tilted so the plane passing through the overlapping surface does not intersect the rotational axis of the drum on its active width.
