摘要: 超大型环件径轴向轧制过程失稳、失圆等异常状态常导致轧环终止和产品质量波动。提出了轧环过程稳定性和圆度自适应控制方法,从历史数据中归纳人工控制经验知识,建立了基于锥辊转速模糊调节的轧制稳定性控制方法,制定了基于导向力反馈的轧制圆度控制策略。运用ABAQUS有限元软件和子程序二次开发,设计了轧环过程稳定性和圆度自适应控制子程序,建立了16 m超大型环件轧制过程控制有限元模型,仿真分析了锥辊转速模糊调节、导向力反馈以及基于限幅滤波的锥辊转速模糊调节+导向力反馈综合控制下的轧环过程偏移量和圆度误差变化规律,结果表明该方法与常规规划控制相比,环件偏移量减小了48.3%,圆度误差减小了61.8%。

Abstract: In the radial and axial rolling processes of super large rings, such abnormal conditions as instability and loss of roundness often led to rolling termination and quality fluctuation. An adaptive control method of stability and roundness of ring rolling processes was proposed, and the experience of manual control was summarized from historical data. The stability control method of ring rolling was established based on fuzzy adjustment of cone roll revolution speed, and the roundness control strategy of ring rolling was developed based on the guide force feedback. Using ABAQUS software and subroutines, the adaptive control subroutines of ring rolling processes were designed, and finite element models of adaptive control of 16 m super large ring rolling processes were established. The rings offset and roundness error change rules were analyzed during ring rolling processes in different methods of cone roller revolution speed fuzzy adjustment, guide force feedback and cone roller revolution speed fuzzy adjusting integrated guidance force feedback comprehensive control. The results show that, with regard to the control method, the rings offset is reduced by 48.3% and the roundness errors are reduced by 61.8% compared with the conventional control methods.

Key words: super large ring, radial and axial ring rolling, stability, roundness, intelligent control
