In a cooling section having a plurality of coolant outlets, the coolant outlets are supplied with the coolant via transmission lines and a mutual main line. Individually opening and closing valves are disposed in the transmission lines. An automation device of the cooling section opens and closes the valves at valve-specific opening and closing times during the normal operation of the cooling section in order to apply coolant to the rolling stock according to a quantitative target coolant course. During the determination of the opening times, the automation device considers a respective valve-specific characteristic. In calibration operation of the cooling section, the respective characteristic is initially determined at least for some of the valves by opening and closing the respective valve, and detecting the chronological course of the quantitative coolant flow effected thereby by a measuring arrangement disposed in the main line.

Operating method for a cooling section having centralized detection of valve characteristics and objects corresponding thereto

The invention relates to a method for controlling and/or regulating an industrial process for producing or processing products, wherein a physicomathematical model of the industrial process is formed, with which control parameters for controlling or regulating the industrial process are calculated during the production or processing of the product, a number of measurement values is detected, and the model is corrected with a number of primary correction factors, the number of primary correction factors being equal to the number of measurement values. The method is characterized in that the model is corrected with a number of secondary correction factors, such as with a correction factor reflecting the speed of the phase conversion in the rolling mill to be cooled, and in that the number of all correction factors is greater than the number of all measurement values, wherein at least the secondary correction factors are calculated numerically.

Method for controlling and/or regulating an industrial process

In a method for assisting at least partially manual control of a metal processing line (), in which metal () in strip or slab form or a pre-profiled state is worked, the proportion of at least one metallurgical phase of the metal is continuously determined with respect to at least one specific location of the metal processing line while taking into account operating parameters of the metal processing line () that influence the phase state and/or state parameters of the metal, and the proportion of the least one phase with respect to the specific location of the metal processing line is indicated to an operator.
