Abstract: Sensors detect states of units of a plant for producing and/or treating a rolled product made of metal and transmit them to an automation system. The state signals (Z) are, in part, dimensional signals. The automation system determines, by taking into account the state signals (Z), control signal signals (S) for actuators associated with the units and actuates the actuators accordingly. The automation system includes at least one model-based system which models the behavior of the system and/or of the rolled product in real time. The automation system transmits the state signals (Z), the control signals (S) and/or signals derived therefrom at least in part via an open data network to a human-machine interface arranged at an operating location. The transmitted signals comprise at least one of the dimensional signals. The automation system takes specifications (V) from the human-machine interface in determining the control signals (S).

Abstract: An automation system (1) determines control data (S?), outputs same to controlled elements (5) of the facility (ANL) and thereby controls the facility (ANL). Sensor devices (2) acquire measurement data (M) of the facility (ANL) and at least partly feed same to the automation system (1) and a man-machine interface (3). Said man-machine interface (3) receives planning data (P) from a production planning system (11) and/or control data (S?) and/or internal data (I) from the automation system (1). The interface outputs the data (M, S?, I) to a person (4). It furthermore receives control commands (S) from the person (4) and forwards them to the automation system (1). The automation system (1) processes the measurement data (M) and the control commands (S) when determining the control data (S?). An artificial intelligence unit (9) receives at least part of the measurement data (M), control data (S?) and/or internal data (I) and the data output to the person (4). It also receives the control commands (S).

A state monitoring system (7) determines previous and future anticipated states (Z1) of components of the plant (ANL). A quality determination system (8) determines states (Z2) of output products (Ai) produced and still to be produced by the plant (ANL) and/or past and future states (Z3) of the plant (ANL) as a whole. A maintenance planning system (9) and/or the production planning system (6) receive, from the state monitoring system (7), the states (Z1) of the components of the plant (ANL), determined by the state monitoring system (7) and, from the quality determination system (8), the states (Z2 and Z3) of the output products (Ai) and/or of the plant (ANL) as a whole, determined by the quality determination system (8).

Abstract: A combined continuous casting and rolling system, a control device for such system, and a method for producing rolling stock, e.g., metal strip, using such system are disclosed. The combined continuous casting and rolling system may include a casting device for casting metal and a roll train having at least one roll stand for hot forming the rolling stock, wherein the system is operated such that the rolling stock extends continuously between the casting device and the roll train, wherein rolling stock is continually supplied to the roll train, and wherein a predetermined target thickness progression for the rolling stock is predetermined. Because the thickness progression has at least two different target thicknesses for different sections in the longitudinal direction of the rolling stock and the thickness progression is designed such that particular target thicknesses are set at least twice, longitudinally profiled rolling stock may be produced relatively inexpensively.

The computer determines the temperatures occurring along a respective rotation part of the respective surface elements of the rotary elements and a rotary element shape which forms in the region of a draw-off point on the respective surface element, by a respective rotary element model and using an exchanged enthalpy quantity, the respective contact time with a metal and a respective cycle time exchanged per time unit of a respective rotary element of a casting device with the environment thereof. The temperature of the metal situated in the die region, and the heat flow from the metal to the respective surface element, are determined by a respective metallurgical solidification model and using a metal temperature, the temperatures of the surface elements, the rotary element shape and characteristic metal values.

Abstract: A method operates a continuous annealing line for the processing of a rolled good, in particular a metal strip. A property of the rolled good in relation to a point or a section of the rolled good is fed to a computer-aided model as an input variable. The point or the section of the rolled good is located before or in the continuous annealing line. For the purpose of precise control of the continuous annealing process, at least one material property of the rolled good after the continuous annealing process is simulated by the computer-aided model and compared with a specified target value. If the simulated material property deviates from the target value, at least one process variable of the continuous annealing process is controlled as long as the point or the section of the rolled good is located before or in the continuous annealing line.

Abstract: In situations where first equipment of a first technical installation could hitherto not be monitored based on condition data of the first equipment from the first equipment alone, it is proposed that a first sensor measures first condition data of the first equipment and that art additional sensor measures additional condition data of an additional equipment of an additional technical installation. The first condition data and the additional condition data are transmitted to a sorting unit and processed by the sorting unit into a ranking list. A corresponding sorting unit and a system as well as a corresponding computer program and a computer program product are also disclosed.

Abstract: In a rolling mill train (2; 30; 56) for processing rolling stock (4, 32), at least three rolling stands (10) are directly adjacent in the rolling direction and are driven by electric motors (20) having superconducting windings. It is thereby possible to keep the distances between the rolling stands smaller than with conventional electric drives, thus reducing energy losses during the rolling process. A combined casting and rolling station (40), which is equipped with such an electric motor (20) in the rolling stands, is configured and/or operated efficiently in terms of the required heating power.

Abstract: It is proposed, in an industrial process to use the waste heat from electric converters and electric machines for the heating in a further process step. For this purpose, liquid cooling is used for the elements producing the waste heat. By this, electric or fossil-stored energy is saved, this leading in turn to a direct or indirect reduction in emitted greenhouse gasses.
