Abstract (en)
[origin: WO2023275488A1] The invention relates to a method for preheating at least one working roll for rolling, involving phases of: - determining a target thermal expansion profile, - determining an effective mean temperature profile of longitudinal segments of the working roll and for determining a target mean temperature profile; - activating a plurality of inductors distributed along the working roll in order to reduce a difference between the effective mean temperature and the target mean temperature.
