针对当今国际先进的AGC控制方法,深入地比较了日立公司和Siemens公司厚度控制策略的不同,从理论上分析了它们为提高厚度控制精度所采取的控制思想差异,特别是在秒流量AGC控制策略方面,充分体现两者对于改善厚度偏差手段的不同。最终通过轧机生产厚度控制结果实绩数据,阐述了控制策略的不同只是在现有硬件配置的基础上实现优化设计,最终提出相关冷连轧机高精度厚度控制方案,给采取何种厚度控制策略以启迪和借鉴。
In view of the current international advanced AGC control methods, the differences between the thickness control strategies of Hitachi and Siemens are compared in-depth. The differences in control ideas adopted by them to improve the thickness control accuracy are analyzed theoretically, especially in the second-flow AGC control strategy Aspects, fully reflect the difference between the two means to improve the thickness deviation. Finally, the thickness of the mill production control results of performance data, described the difference between the control strategy is based on the existing hardware configuration to achieve optimal design, and ultimately proposed high-precision thickness control of tandem cold mill program, to take what thickness control strategy to enlighten And learn from.
