Abstract
In this paper, an integrated rolls system deformation calculation model is established based on the influence function method combining with pass schedule calculation, rolls wear and roll thermal deformation calculation, and the corresponding calculation procedure has been developed. Then the influence of work roll bending, work roll shifting and intermediate roll bending on transverse distribution of strip thickness, strip crown, quadratic flatness, and quartic flatness are analyzed with the procedure. According to the analysis result, flatness control strategy of the single-stand reversing cold rolling mill is determined. The flatness control strategy will provide the basis for flatness control presetting of the mill. The practical application shows that the flatness control strategy is suitable for flatness control of the single-stand reversing cold rolling mill.
