Rolling mill with roll deflection bi-dimensionally controlled

摘要

The present invention is generally directed to a rolling mill in which the supporting means are arranged in the middle region of the roll body of the working roll with their length(s) not longer than that of the roll body of the working roll. The supporting means supports or abuts against the middle and lateral roll supports at their central region in the axial direction during the operation of the rolling mill so as to provide central support to the roll supports. As a result, the middle and lateral roll supports and hence the rolls will not deflect or bend under the action of rolling force.
