An apparatus and a method provided for spraying a coolant to a work piece include a coolant feed line, at least one delivery nozzle for delivering the coolant, and shielding means which surround at least part of said delivery nozzle. The shielding means are arranged with the work piece to form an essentially closed space, and said shielding means includes exhausting means for exhausting gas from the essentially closed space, and means for keeping the outside of the shielding means at a temperature above the dew point.

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.
