本文研究曲率不对称轧制结合现有的结果，从八个实验和九个数值以前的研究。这些之前的结果被数字化并拟合线性回归模型，该模型解释了这些数据中65%的方差。结果表明，以往的研究结论与其他研究结果相矛盾，对轧制过程中曲率产生的基本机理也没有达成共识。从现有的曲率预测分析板模型的结果也与以前的结果进行了比较，协议被证明是足够的。未来的工作显然需要实现准确的曲率预测，希望这里收集的证据将为未来的调查和模型提供信息，以确保考虑相关的参数范围。
This paper investigates curvature in asymmetric rolling by combining existing results from eight experimental and nine numerical previous studies. These previous results are digitised and a linear regression model fitted which explains 65% of the variance in these data. It is found that conclusions from several previous studies are contradicted by other previous studies, and that there is no consensus on the fundamental mechanism of curvature generation in rolling. Results from an existing curvature-predicting analytic slab model are also compared with the previous results, and the agreement is shown to be adequate at best. Future work is clearly needed to enable accurate curvature prediction, and it is hoped that the evidence collected here will inform future investigations and models to ensure the relevant range of parameters are considered.
