Abstract: A system for the continuous casting and subsequent flat rolling of a steel strip with an austenitic and/or ferritic microstructure and a thickness of less than 1.0 mm comprises a casting device with which a raw steel strip with a thickness in the range of 1.50 to 4.0 mm can be continuously cast. At least one hot rolling stand is coupled to the casting device, with which the raw steel strip can be roughed into the steel strip immediately after the casting process while still in the austenitic and/or ferritic microstructure range. At least one rolling module is arranged immediately after the hot rolling stand coupled to the casting device. The rolling module includes, in this order, a cooling device, a heating device and a hot rolling stand with which the roughed steel strip can be hot-rolled in the austenitic and/or ferritic microstructure range to specifications into the steel strip.

Abstract: A method for producing steel strip, in particular hot strip in the form of coiled coils or in the form of folded individual sheets, in which a steel melt is first produced, this is then formed into a strand in a continuous casting system, the strand is then fed into a heating unit and the heated strand is then rolled into hot strip in a subsequent rolling mill. The casting of the strand, the passage through the heating unit, and the rolling take place in a continuous process. To be able to produce hot-rolled steel strips in the most energy-efficient way possible and to make these strips available for further processing into high-quality cold-rolled and, if necessary, coated strips, the invention provides that, first of all, a steel melt is produced.

Abstract: A method for controlling a metallurgical plant in an open-loop and/or closed-loop manner. In order to enable simple, robust, and economical open-loop and/or closed-loop control of a metallurgical plant, the method includes the following steps: detecting a metal microstructure of a metal product after the performance of a processing step on the metal product by the plant; producing at least one microstructure characterization that characterizes the detected metal microstructure; comparing the produced microstructure characterization with at least one specified limit criterion; and performing a further processing step, which follows the processing step, on the metal product by the plant only if the produced microstructure characterization meets the specified limit criterion.
