Abstract
The invention provides a roll profile for work rolls for both shape control and free ruled rolling. Each of the work rolls has a tapered end. The curve of respective tapered end is a quartic curve represented by a formula y(x)=a+ax+ax+ax+ax, xε[0,Le], y(x)ε[0,He]. It is possible to partially eliminate the asymmetric deformation due to the difference between abrasion of the upper and lower rolls. Further, closed type abrasion of conventional roll is changed into open type abrasion and box shaped abrasion of conventional roll is eliminated, which eliminating 'cat ear' hole and fulfilling the requirements of free ruled rolling.
