For controlling the temperature of the working rolls and hence the flatness of the material during the rolling of aluminium strip or foil, the system consists of a set of internally cooled work rolls 3 , and a means 7 to externally heat these rolls by induction heating. The rolls are internally cooled by means of circulation of cooling medium 6. An additional strip lubrication device 5 applies a dedicated lubricant to the roll and/or material to lubricate the process. The induction heater(s) may be split into individually controllable zones, controlled by a process control system which determines the control strategy from either a strip flatness measuring device or a predictive process model in order, by thermal growth/contraction, to create the best roll profile for rolling flat strip.
