Abstract
For controlling the flatness of the strip during the rolling of aluminum strip or foil, the system consists of a full width bank of cryogenic roll cooling devices acting on the roll(s) and a full width bank of roll heating devices also acting the roll(s). Both or either of the cooling and heating banks are divided into individually controllable zones. A process automation system controls the action of the cooling and heating banks via feedback from a strip shape meter and/or a predictive process model, in order, by thermal growth/contraction, to create the best roll profile for rolling flat strip.
