Abstract: The invention relates to a method for the direct reduction of oxidic iron carrier particles to a reduction product in a fluidized bed through which a reduction gas containing 30-100 mol % hydrogen H2 flows in crossflow. At least 90% by mass of oxidic iron carrier particles introduced into the fluidized bed have a particle size of less than or equal to 200 micrometers. The superficial velocity U of the reduction gas flowing through the fluidized bed is set between 0.05 m/s and 1 m/s such that, for the particle size d equal to d30 of the oxidic iron carrier particles introduced into the fluidized bed, it is above the theoretical suspension velocity Ut and is less than or equal to Umax.

Abstract: A dynamic production planning method for a continuous casting plant for casting a strand with a production system which has a predefined production plan, which method includes comparing target production parameters with actual production parameters. If the actual production parameters deviate from the target production parameters, a strand image is created on the basis of actual production parameters. With the aid of the calculated strand image, a check is carried out within the predefined production plan and, if possible, a new production plan is created. If no solution can be found from the predefined production plan, the strand image is transmitted to a production planning system. The production planning system creates a new production plan from all available orders on the basis of a predefined optimization criterion. The new production plan is subsequently transmitted to the production system.

Abstract: A method for cold rolling rolled stock (2) in a mill train (1) with multiple roll stands (3 to 7). An upper limit temperature and/or a lower limit temperature is provided for a rolled stock temperature of the rolled stock (2) for at least one rolling pass, and the rolled stock temperature is controlled and/or regulated by at least one control or regulating measure such that during the at least one rolling pass, the rolled stock temperature does not exceed the upper limit temperature specified for the rolling pass and/or the rolled stock temperature does not fall below the lower limit temperature specified for the rolling pass.

Abstract: A cooling bar (1) for cooling rolled material (5) being moved in a transport direction (3) and in particular for reducing temperature differences in the temperature of the rolled material (5) transversely to the direction of transport (3). The cooling bar (1) has several full jet nozzles (11) by means of which a coolant beam of a coolant with an approximately constant jet diameter can be distributed to the rolling stock (5) in the direction of distribution (15). A cooling device has at least two cooling bars (1) of that type. The cooling bars extend transversely to a transport direction, one behind the other. Each cooling bar has a respective different pattern of jet nozzles and selection of applicable pattern of jet nozzles in their respective bars selectively cools the rolled material transversely to the transport direction.

Abstract: A stripping device (7) for a roll stand (1) includes a stripper carrier (15) and a stripper (17) arranged on the stripper carrier (15). The stripper (17) has a main body (19) produced from a fiber-plastic composite. The main body has a main body bottom side (23), which contacts the stripper carrier (15). A felt layer (21) is arranged on a main body top side (25) of the main body (19) which is opposite the main body bottom side (23).

Abstract: Energy-efficient production of a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1), which modifies the known processes for producing a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1) so that the ferritic hot-rolled strip (6) can be produced significantly more energy-efficiently but nevertheless has good metallurgical properties and a good surface quality.

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). The artificial intelligence unit (9) processes the data (M, S′, I) and control demands (S) received and determines evaluation results (A) therefrom and makes the latter available to the person (4) and/or to the production planning system (11) and/or sets them for the automation system (1) in the form of control commands (5″) directly or via the man-machine interface (3). The data (M, S′, I) received by the artificial intelligence unit (9) are at least to some extent dimensional data. Said dimensional data (M, S′, I) comprise at least one image captured by a sensor device (2) or an image output via the man-machine interface (3), part of such an image, a time sequence of such images or a time sequence of a part of such images or an acoustic oscillation or an acoustic oscillation spectrum.

Abstract: A device (1) for inductive heating of a workpiece (2) in a rolling mill, the device (1) including: a converter (3) for creating an alternating voltage, a capacitor bank (6) electrically connected to the converter (3), and having a plurality of capacitors (7) connected in parallel, a working field (8), in which an upper coil (10) and a lower coil (11) are arranged. The workpiece (2) is able to be passed between the coils (10, 11) and is thereby inductively heated by cross-field heating. A housing (4) arranged next to, below or above the working field (8). The converter (3) and capacitor bank (6) are arranged in the housing (4). The coils (10, 11) are each electrically connected to the capacitor bank (6) by a flexible cable (12, 13). The cable (12, 13) is a coaxial cable (27), with one phase of the alternating voltage applied to an inner conductor (28) and the other phase of the alternating voltage applied to an outer conductor (29) of the coaxial cable (27). The cables (12, 13) are cooled by a fluid, such as air or water (21).
