Abstract: A 20-high rolling mill configured for rolling a metal strip, which includes a housing system comprising two parts capable of moving relative to one another, respectively forming an upper housing part, configured to transmit a clamping force to the four backup roller assemblies, of the upper group, and an upper housing part, configured to transmit a clamping force to the four backup roller assemblies of the lower group, and a door cooperating, in a closed position, with a peripheral frame of a fixed frame structure of the housing system surrounding the maintenance window, said door closing, in a sealed manner, said maintenance window. A system of axial stops for the second intermediate rolls accompanies the movements of the upper and lower housing parts.

Abstract: A tool intended to be handled by a handling system, the grasping tool including: a support frame forming at least one pair of compartments for the storage of two work rolls, independent gripping systems including a first gripping system configured to secure one end of a work roll in a first compartment and a second gripping system configured to secure one end of a work roll in a second compartment, a push/pull system including one or more actuating cylinder(s) configured to extract or insert the worn/new rolls from/into the compartment by a selective movement of each of the gripping systems associated with the compartments, by causing a movement of the work roll according to an axis of the roll.

Abstract: A method for changing work roll in a rolling mill which limits the risk of scratching the work roll, or even the risk of scratching the metal strip, upon extracting or inserting the work roll, by virtue of a mechanical separation element, in particular of the branches of a fork system, inserted by a robotic element.

Abstract: Disclosed is a rolling mill including: a stand; two working rolls, two support rolls, and two intermediate rolls; lateral support rolls, able to support the working rolls laterally, each lateral support roll being borne by a support arm, mounted with the ability to pivot; load spreading beams and a mechanism for applying a preload on each support arm, including at least one preload actuating cylinder; one or more spray nozzles for a lubricating/cooling fluid, and wherein at least one of the nozzles, is carried on one of the support arms and in which the fluid supply circuit for the at least one nozzle comprises a device for connection/disconnection with the support arm with actuator. The actuator is an actuator distinct from the actuating cylinder of the mechanism for applying a preload.

Abstract: A treatment device for drying a laminated strip includes: lower and upper crosspieces extending transversely to and on either side of the metal strip, the upper crosspiece embedding an upper pressure cylinder with supporting rollers, the lower crosspiece embedding a lower pressure cylinder with the supporting rollers, the actuator and guide enabling the crosspieces to pass from a retracted idle position to a close working position, for which the lower and upper pressure cylinders, arranged on either side of the strip, transversely to the direction of travel, are each intended to be pressure-applied on the strip by the supporting rollers distributed along the length of the pressure cylinder, and along at least two rotating axes parallel to the longitudinal axis of the pressure cylinder. A first compartment supports all the supporting rollers. A second compartment supports the pressure cylinder. Each compartment is a removable element of the crosspiece.

Abstract: Disclosed is a spray ramp intended to lubricate and/or cool a laminated strip and/or pressure cylinders of a mill, including: a tubular shaft of which the hollow interior volume forms a fluid admission chamber; a chassis rigidly connected to the external wall of the shaft, extending along the tubular shaft; a plurality of nozzles distributed over the length of the chassis and supported by the chassis, arranged such that the jets form a fluid curtain; and a pipe system, inside the chassis, ensuring the supply of the nozzles from the through-bores provided in the tubular wall of the hollow shaft. The pipe system includes at least one pressure levelling chamber extending over the whole active length of the chassis and through which all the fluid supplying the plurality of nozzles passes.

Abstract: Disclosed is a rolling mill for a metal strip, including: a holding cage; an assembly of superimposed rolls with substantially parallel axes, including lower and upper working rolls, defining the gap for passage therethrough, and two respectively lower and upper supporting rolls respectively applied to the working rolls on the opposite side to that of the gap, each roll having two rotatably mounted ends, each on a bearing carried by a chock; and a system for clamping the chocks of the working rolls along the axis of the roll, while allowing the chocks to slide along a guide, following the clamping plane including a mechanical unit using the closing movements of the holding cage in order to switch from a retracted position, allowing the withdrawal, along the axis thereof, of the working rolls out of the holding cage, into a locking position, ensuring locking of the chocks.
