并基于不同条件的计算结果，回归出轧辊凸度变化对辊缝设定影响的计算模型。
The mathematic model of the influence of roll crown variation on gap setting can be got by regression based on lots of calculation results.
首次推导出了CVC轧辊凸度与轧辊轴向移动量之间的非线性关系，提出了凸度极值的概念。
The nonlinear relationship between roll crown of CVC rolls and their shift amount is first deduced. The concept of crown limit is first given in the paper.
根据影响函数法计算轧辊凸度对辊缝设定的影响，当保持工作辊和支承辊凸度不变，则轧制力与辊系弹性变形呈线性关系，工作辊和支承辊凸度的变化对直线的斜率几乎没有影响。
By the influence function method the influence of plate width, work roll radius, backup roll radius, work roll crown, backup roll radius and rolling force on gap setting were calculated.
