Abstract To obtain a better strip shape, this paper proposes a new micro-scale roll profile control technology. According to the principle of the technology, it can be called roll profile electromagnetic control technology (RPECT). To achieve multi-point and real-time measurement the profile of electromagnetic control roll, the new roll profile test technology is proposed. Relying on the RPECT and new roll profile test technology, a φ270 mm×300 mm roll profile electromagnetic control experimental platform (RPECEP) is designed and built. An electromagnetic-thermal- mechanical coupled axisymmetric simulation model with the same size is established. Through experiments and simulations, RPECT is confirmed to achieve micro-scale flexible roll profile adjustment. An all-around comparison of experimental results and calculated results confirms that the new roll profile test technology is feasible and the calculatde results agree well with the experimental results. Based on the model, the variation of the roll profile is analysed for different electromagnetic parameters; the structures and positions of the electromagnetic stick, reasonable electromagnetic parameters and optimal time period for the roll profile control are determined, and methods for changing the number of roll profile curves are given.

柔性辊型电磁控制规律的理论与实验研究

摘要 为了获得更好的带钢形状，本文提出了一种新的微尺度辊型控制技术。根据该技术原理，可称为辊型电磁控制技术（RPECT）。为实现电磁控制轧辊轮廓的多点实时测量，提出了新的轧辊轮廓测试技术。依托RPECT和新型辊型测试技术，设计并搭建了φ270 mm×300 mm辊型电磁控制实验平台（RPECEP）。建立了相同尺寸的电磁-热-机械耦合轴对称仿真模型。通过实验和模拟，确认RPECT可以实现微尺度柔性辊型调整。实验结果和计算结果的全面比较证实了新的辊型测试技术是可行的，计算结果与实验结果吻合良好。在该模型的基础上，分析了不同电磁参数下轧辊轮廓的变化；确定了电磁棒的结构和位置、合理的电磁参数和辊型控制的最佳时间段，并给出了改变辊型曲线数量的方法。
