Abstract
ABSTRACTEnsuring product quality requires the accurate detection of strip flatness during cold rolling. For cold rolling mills with intermediate roll shifting control, the uneven stiffness induced by the shifting process can cause the strip to tilt in the mill, which can affect the accuracy of strip flatness detection. In this study, the strip tilt is defined, and a finite element model of the S6-high mill is constructed using ABAQUS software to study the strip’s deflection and flattening behaviour during the rolling process and the effect of different rolling process parameters on the strip tilt. The specific spatial position of the rolls during the rolling process is also examined, and the main structure of the mill is identified as the primary cause of strip tilt. This research provides a theoretical basis for the strip’s absolute position change in the rolling process, which can enhance the measurement accuracy of flatness detection roll in the future.KEYWORDS: Tilting of stripfinite element analysisroll deflection Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe authors confirm that the data and material supporting the findings of this work are available within the article.Additional informationNotes on contributorsTieheng YuanTieheng Yuan, Male, 1997-, Doctoral candidates, University of Science and Technology Beijing.
