Abstract: A rack system (SR) for the storage of rolls of a rolling mill including a support frame (Cha) configured to support several racks (Rac), distributed over the length of the support frame at different positions along the length of the rack, at least one first rack (Ra1) and one second rack (Ra2) configured to rest while bearing on the support frame (Cha). The first rack (Ra1) is configured to pass from a storage position (PS) for which said first rack (Rac1) rests bearing simultaneously on a first support (Cha1) and a second support (Ch2) of the support frame (Cha) up to a transport position (PT) for which the first rack (Rac1) is configured to be stowed in the free clearance (IT) below the level of the second rack (Rac2) resting on said support frame (Cha) at an intermediate position.

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: A method for recycling and filtering rolling oil implemented for a rolling mill M requiring a rolling oil nominal flow rate comprised between 4000 l/min and 30000 l/min in an oil recycling and filtering plant having a circuit including, successively, according to the flow direction of the oil: a dirty oil tank, collecting the rolling oils coming from the rolling mill, a filtering system including several oil filtering devices configured to perform an oil filtering in parallel, a clean oil tank from which the rolling mill is fed with rolling oil at the nominal flow rate. The unclogged muds undergo a secondary treatment by continuous and turbulence-free decantation, thanks to a feed-in of the decanter with mud regulated by a pump.

Abstract: A rolling mill, in particular a cold rolling mill, including: rolls or even sets of rollers comprising at least one pair of work rolls capable of defining a roll gap of a strip to be rolled, at least one bar for spraying a lubricating and/or cooling fluid, disposed near the plane of the strip to be rolled, a stand inside of which the rolls are arranged, at least one device for adjusting the inclination of the at least one bar comprising an actuator, such as a hydraulic cylinder configured to change the inclination of the bar around the pivot axis. The actuator of the device for adjusting the inclination is arranged, on the second side of the stand, opposite to the first side of the maintenance window.

Abstract: A robotic system for a plant for rolling a metal strip, the plant including a rolling mill having a roll stand and a set of rolls, internal to the stand, the roll stand having an access opening, possibly closed by a door system, the metal strip extending longitudinally according to a horizontal direction X, and transversely according to a horizontal direction Y, the direction Y being parallel to the axes of the rolls of the rolling mill. The robotic system is suited to ensure the operations of replacing rolls of the rolling mill, by extraction of the worn rolls from the stand of the rolling mill and the deposition thereof on a rack disposed laterally, and/or insertion of new or rectified rolls into the roll stand from rolls disposed in a rack.

Abstract: Disclosed is a rolling method for rolling a strip including: rolling the strip by a pair of working rolls; transmitting a rolling force to the working rolls by a pair of support rolls; holding each of the working rolls by a pair of side support rollers; supporting each side support roller by two rows formed by rollers; supporting each row formed by the rollers, by a bearing support carrying rollers, the bearing support mounted pivotally on an articulation axis. The dimensions of a first interspace between the side support roller and the support roll and a second interspace between the strip and the assembly consisting of side support roller and bearing support vary in the course of the rolling. The method includes adjusting the dimension separating the axis of the support roll and the axis of the side support roller defining the first interspace.

Abstract: Disclosed is a method for changing the rolls on a rolling mill for rolling a metal strip, carried out using a Quarto rolling mill, including lower and upper working and support rolls. The installation includes a system for extracting the working rolls and the support rolls, including: an actuator pushing the rolls out of the roll stand extraction; a coupling head, secured to the actuator, situated in a position of opening of the roll stand, including: a first coupler driving the chock or the end of the lower working roll, on the rolling-mill drive side; a second coupler driving the chock of the lower support roll, on the rolling-mill drive side. The first and second coupler allow successive extractions of the working rolls and then of the support rolls from the roll stand using the actuator of the extraction system. Also disclosed is a related rolling mill installation.

Abstract: A rolling mill includes a frame, at least one pair of working cylinders capable of defining the air gap of the strip to be rolled, as well at least one line for spraying a lubricant and/or coolant fluid, arranged next to the plane of the strip to be rolled. The line is rigidly connected to the frame via a hinged mechanical link, the mechanical link including a resilient unit forcing the line into at least one operational position, toward the plane of the strip, and allowing, in the event that a force on the line tends to separate the line, greater than a threshold value, the deformation of the resilient unit against the return force thereof, and thus the retraction of the line toward a position separated from the at least one operational position.

Abstract: A device for filtering oil, including: a tank including an oil inlet and a cover; an at least one removable plate, inside the tank, that can be removed from the tank via the upper opening of the cover. The at least one plate removably receives filtering cartridges. The plate is hollow, forming a collector for the oil filtered by the cartridges of the plate. The plate includes an outlet for filtered oil removably connected to a corresponding outlet of the tank via a connector. The connection includes a first portion rigidly connected to the plate and a second portion rigidly connected to the tank, that are capable of mutually cooperating via a seal in order to provide a sealed connection between the oil outlet of the plate, and the corresponding outlet of the tank, and in order to allow maintenance operations to be performed without intervening in the tank.
