【Abstract】 Comprehensive function of varying contact length backup roll(VCR)is analyzed by using the finite element model for elastic deformation of rolls.VCR can evidently improve the shape control performance of rolling mill and make the quality of strip shape better.ln addition,VCR has an excellent self contour holding,and can reduce the maximum of contact pressure between rolls to avoid spalling of backup roll.Meantime,long time systemic tests were proceeded on large industrial mills,and these functions of VCR were verified.更多还原
