Abstract: A metal strip is guided on transportation rollers through a strip treatment installation. The installation includes successive strip movement control devices along a transportation direction. The strip movement control devices detect and adjust the position of the strip transverse to the transportation direction. A method for operating the installation includes: detecting the position of the strip transverse to the transportation direction by sensors of upstream strip movement control devices; identifying properties that influence the position of the strip transverse to the transportation direction of the strip by the sensors; assigning the identified properties of the strip to corresponding points or segments of the strip; and proactively adjusting the position of the strip transverse to the transportation direction at downstream strip movement control devices based on the properties for the corresponding points or segments of the strip identified by the upstream strip movement control devices.

Abstract: The invention relates to a method for the heat treatment of a metallic product (P), in particular a strip or sheet, in which the product (P) is controlled and/or regulated by means of a control and/or regulating device (100) controlled and/or regulated furnace device (110) is carried out at a predetermined speed in a conveying direction (F), the product (P) being heated up to a first point (I) and then up to a second location (H) or is cooled down to a third location (III). The method according to the invention is characterized in that an austenite content of the product P is predicted for the second location (H) or for the third location (III) and it is then checked whether this austenite proportion is within a desired target range, in which case If a deviation from this is found, for example a zone temperature of the furnace device 110 is adjusted and preferably regulated in such a way that the austenite proportion of the product P predicted for the second location (II) or for the third location (III) is within a desired quality window for the target value of the austenite content.

Abstract: The invention relates to a system (1) for controlling a production plant (3) consisting of a plurality of plant parts (2), in particular a metallurgical production plant for producing industrial goods such as metal semi-finished products and/or metal end products,



wherein each plant part (2) has an input quality window (4), an output quality window (5) and a process window (6),
wherein the input quality window (4) of a plant part (2) defines the quality characteristics of the input product that are required by the plant part (2) and the output quality window (5) of a plant part (2) defines the quality characteristics of the output product that are allowed by the plant part (2) after processing the input product,
wherein, in a production plant (3) consisting of the plurality of plant parts (2), the output quality window (5) of an upstream plant part (2) corresponds to the input quality window (4) of the downstream plant part (2),
wherein the process window (6) defines the setting values (7) that can be implemented by the respective plant part (2) for a plant automation unit of the plant part (2),
wherein each plant part (2) detects the current state by means of sensors (8) and adapts the process window (6) of the plant part (2) to the detected current state, and
wherein the system (1) for controlling the production plant (3) consisting of the plurality of plant parts (2) determines setting values (7) for the respective plant automation unit for each plant part (2), the setting values being within the process windows (6) and that the product produced in the production plant (3) meets the quality characteristics required by the input quality windows (4) and output quality windows (5) of the plurality of plant parts (2).




The invention further relates to a corresponding method and computer program.

Abstract: A method for operating a coating device for coating a metal strip. The corresponding coating device has an electromagnetic strip-stabilizing device having a plurality of electromagnetic actuators or coils for applying forces to the metal strip. In order to ensure that the strip-stabilizing device is operated only within the operating limits thereof, the magnitudes of the set currents for the actuators or the coils are compared with a specified current threshold value or the forces applied to the metal strip by the actuators are compared with a specified force threshold value and the correction roller is moved into such an adjustment position that the magnitudes of the set currents are below the current threshold value or the magnitudes of the forces are below the force threshold value.
