Abstract: Method and control device for controlling a cooling device (10) which is set up to control the temperature of a rolling stock, preferably metal strip (B), which the cooling device (10) runs through along a conveying direction (F), the cooling device (10) preferably in front of a rolling train is arranged and the method comprises: determining a total enthalpy of the system formed by the rolling stock; Determining a measure for the formation of scale, which preferably comprises a scale factor that depends on the chemical composition and the surface temperature of the rolling stock; Calculating a temperature distribution and/or average temperature in the rolling stock on the basis of a temperature calculation model, in which the determined total enthalpy and the measure for the formation of scale are included; and setting a cooling capacity of the cooling device (10) taking into account the calculated temperature distribution and/or average temperature in the rolling stock.

Abstract: A method for open-loop and/or closed-loop control of a heating of a cast or rolled metal product, includes the steps of determining the total enthalpy of the metal product from a sum of the free molar enthalpies (Gibbs energy) of all phases and/or phase fractions currently present in the metal product; determining a temperature distribution within the metal product by means of a dynamic temperature calculation model using the total enthalpy determined; and open-loop and/or closed-loop controlling of the heating of the metal product as a function of at least one output variable of the temperature calculation model.
