Frame S1 and one or more additional frames are selected as virtual indirect measuring instruments for the strip performance. A load cell is provided on the frames that are selected as the indirect measuring instruments for the strip performance, and deformation resistance fluctuation of the supplied materials of the frame S is calculated. Finally, the feed-forward adjustment amount of each frame is calculated. The present invention measures the deformation resistance of each section of the strip of the supplied materials through the selected frame, reducing the fluctuation of the thickness of the finished products of the strip and ensuring stable rolling."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Performance feed-forward thickness control method in tandem cold mill","description":"The present invention relates to the field of strip cold rolling, and in particular to a thickness control method for strips in a tandem cold mill.
