摘要 传统的高速棒、线材夹送辊没有在线夹持控制机理和智能伺服控制系统,无法对夹持力进行在线控制和实时调整,对于上游工序造成的料形伸缩、张力变化、钢温差异缺少兼容适应能力,容易在高速轧制下发生堆钢、拉断事故。由于缺少智能夹送辊研发的关键技术,尤其是夹送辊新型传动结构和在线夹持力控制模型和系统,高棒、高线智能夹送辊设备全部依赖进口。通过分析夹持机构夹送原理,建立了智能夹送辊夹持力分析计算模型。根据不同轧制工艺参数计算并确定了夹送辊主要设备参数。通过实际项目的实施,说明夹送辊工艺参数设定、设备结构参数设计合理,夹送辊工作可靠,可以满足高速棒材生产线长期稳定运行的需要。 Traditional high-speed rod and wire pinch roll cannot control and adjust the clamping force online and in real time,because there is not online clamping control mechanism and intelligent servo control system.Thus,it lacks compatibility and adaptability to material type expansion,tension change and steel temperature difference caused by the upstream process,and it is easy to cause steel pile and break accidents under high-speed rolling.Due to the lack of the key technology of intelligent pinch roll research and development,especially the new transmission structure of pinch roll and the on-line clamping force control model and system,the intelligent pinch roll equipment of high-speed bar and wire lines all rely on import.The clamping force analysis and calculation model of intelligent pinch roll is established by analyzing the clamping principle of clamping mechanism.According to different rolling process parameters,the main equipment parameters of the pinch roll were calculated and determined.Through the implementation of the actual project,it shows that the setting of the technological parameters of the pinch roll,the design of the structural parameters of the equipment are reasonable,and the pinch roll works reliably,which can meet the needs of the long-term stable operation of the high-speed bar production line.
