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: 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.
