Abstract: A device and a method for cooling metal strips or sheets conveyed on a conveyor line, in particular hot-rolled strips in the outlet of a rolling train. For these purposes, the device includes at least one cooling beam extending across the width of the conveyor line, and the cooling beam features a connection point to which a supply tube for cooling liquid can be connected, and a number of discharge openings arranged along a longitudinal axis of the cooling beam, such that cooling liquid can be discharged through the discharge openings in the direction of the metal strip or sheet that is to be cooled. Associated with each of the individual discharge openings is a respectively adjusted flow area, such that the flow areas of the respective discharge openings decrease in a direction leading away from the connecting point along the longitudinal axis of the cooling beam.

Abstract: The invention relates to a method for the open-loop and/or closed-loop control of a heating of a cast or rolled metal product, comprising the following steps: —determining the total enthalpy of the metal product from a total of the free molar enthalpies (Gibbs free 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 by using the determined total enthalpy; and —open-loop and/or closed-loop controlling of the heating of the metal product according to at least one initial variable of the temperature calculation model.

Abstract: A method for controlling a cooling device which is set up to control temperature of a rolling stock such as a metal strip, which runs through a cooling device along a conveying direction of a rolling train. The cooling device is arranged upstream of the rolling train. The method includes determining total enthalpy of a system formed by the rolling stock; determining a measure for the formation of scale, which includes a scale factor that depends on chemical composition and surface temperature of the rolling stock, and a heat transfer coefficient of the scale; calculating a temperature distribution and/or average temperature in the rolling stock based on 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 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.
