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.

Abstract: In a method for preventing a collision of a load of a crane with an obstacle, a height profile of the obstacle is captured along a trajectory of movement of the load by at least two sensors for distance measurement. Signals of the sensors are transmitted via at least two communication channels to a controller having at least two operating systems. At least one of the operating systems has a safety program in a secure area. The obstacle is identified along the trajectory via the height profile. The controller includes a secure communications interface for transmitting signals from the controller to a crane control.
