Invention Patent: B "COMBINED REGULATION SYSTEM FOR THE PRODUCTION OF PRODUCT PROPERTIES DEFINED, IN THE LAMINATION OF STEEL QUALITIES IN THE AUSTENITIC RANGE, AUSTENICALLY-FERRITICALLY AND FERRITIC MIXTURE" D. The invention relates to a combined regulation system for the production of defined product properties, in the rolling of steel qualities in the austenitic range, mixed austenitic-ferritic and ferritic, using a mediation process to determine the cylinder gap of a pair of cylinders by detecting the absolute position of the working or support cylinders on the side away from the cylinder slot by means of an optical position measurement. In this case, in relation to the absolute measured position of the cylinders, by means of sensors arranged side by side along the cylinder, the upper or lower corner of the lower cylinder, respectively, on the length of the balloon, is detected by segments. The measurement results, using a model, which, in addition to the influences of the bending and cylinder adjustment systems, considers the bending deformations of the cylinders, the flatness between working cylinders, the flatness between the working cylinder and the lamination material, as well as the wear and thermal bulging of the cylinders, are properly regulated, which influences the geometry of the slot of the cylinder and the rolling material, which realizes, in addition to the required absolute thickness, the required thickness profile and flatness criteria.
