Abstract

In a rolling process for reverse thermomechanically rolling an aluminum plate involving a plurality of rolling passes, identifying data are determined for thermally guiding the rolling process. Then a value of a state variable, from which a temperature of the aluminum plate can be deduced, is continuously measured and a pass schedule is determined for the rolling process on the basis of the value of the measured state variable and of the identifying data. The pass schedule provides for a rolling pause between at least two successive rolling passes, during which rolling of the aluminum plate is interrupted for cooling purposes.
