Abstract：For 2250 mm hot continuous rolling mill,the investigation was carried out to study on the work roll end contact during rolling at last stand using Finite Element Method(FEM),Roll contact deteriorates shape controling performance.The influence of strip specification and rolling force on roll contact was obtained by calculation, and negative effect of roll contact on shape controling performance was also revealed. By comparative study, varying contactlength backup roll(VCR) as a technical countermeasure was proposed and, good effect was obtained in production.
