CA 1073712

ABSTRACT A rolling mill having a roll stand with back-up rolls and two cylindrical work rolls. The work rolls have roll- pass grooves associated in pairs with different roll-pass areas. The driving mechanism of the rolling mill is coupled to the back-up rolls which excercise constant pressure on the work rolls during rolling so that these are in hard mutual contact and rotate with the back-up rolls. The work rolls are axially displaceable in the roll stands between the back-up rolls when the latter are open so that a desired roll-pass groove can be positioned with its centre line coinciding with the central plane of the rolling mill.
