Abstract
In a sheet rolling mill having work rolls and backup rolls, rolling of flat sheets is facilitated by controlling constant the transverse rigidity or deflection in the direction of width of rolls. The rolling force is detected, and based on the rolling force thus detected, the value for correcting the crown of the work roll is calculated by a transverse rigidity coefficient and a function determined by sheet thickness to control the transverse rigidity.
