Abstract (en)
[origin: WO2021223937A1] the invention relates to a method for the open-loop or closed-loop control of the temperature of a steel strip during hot working in a hot strip mill. A higher-level open-loop or closed-loop control involves a process model which predicts the temperature development of the hot strip. The target values of the individual units are adjusted on the basis of this predicted temperature development.
