Abstract:

To mitigate instability and out-of-roundness in ring rolling processes, this paper presents an adaptive control approach for roll motion trajectory using ring offset and roundness error as feedback. A finite element model was established to compute these two parameters. Through secondary development of existing software, separate control strategies for guide roll, mandrel, and axial roll were designed, together with an integrated control scheme combining all three rolls. Experimental results demonstrate that the integrated method overcomes the limitations of individual strategies, substantially reduces both offset and roundness error, and effectively improves rolling stability.

Key words: ring rolling, rolls, adaptive control, offset, roundness error

摘要:

针对环件轧制过程中的失稳、失圆问题,提出一种基于环件偏移量和圆度误差的轧辊运动轨迹自适应控制方法。首先建立环轧有限元模型,计算环件偏移量和圆度误差;随后对现有软件进行二次开发,设计了基于偏移量的导向辊控制器、基于圆度误差的芯辊控制器、基于圆度误差的锥辊控制器,以及基于三种辊的综合控制器。结果分析表明,综合控制方法能克服单一控制的局限性,显著减小偏移量和圆度误差,有效提高环件轧制的稳定性。
