Abstract

A cold rolling mill has groups of paired working rollers (10) with supporting rollers (12), followed by six pairs of roller frames with intermediate rollers (11). The working rollers and intermediate rollers have limited axial sliding freedom. The cold rolling mill combines CVC/CVC(plus technology, Per Cross Technology, and the use of strip edge-orientated axial slip of the working and intermediate rollers. The CVC/CVC(plus technology employs CVC roller contours, in which each working roller or intermediate roller has an extension that embraces the side shift zone. The Per Cross technology facilitates azimuth swivel movement of the working and intermediate rollers parallel to the plane through which the strip advances. The strip edge-orientated axial slip of the working and intermediate rollers facilitates equal and opposite shift of these rollers relative to a neutral position.
