摘　　要：以首钢顺义冷轧薄板有限公司1850mm冷连轧机为研究对象,根据AGC控制基本原理,给出了AGC系统中前馈AGC、监控AGC及秒流量AGC的算法。同时,分析研究了AGC系统的控制策略,给出了前部机架常规秒流量、扩展秒流量控制模式和后部机架A、B、C3种控制模式的控制方式及特点。应用效果表明,采用前部机架扩展秒流量模式结合后部机架模式C控制,成品厚度精度满足现场生产要求。Based on the fundamental of automatic gauge control, the algorithms of feed forward AGC, monitor AGC and mass flow AGC are presented for Shougang Shunyi 1850mm tandem cold mill. Meanwhile, the strategy of AGC system is detailed studied. The control methods and characteristics are presented for the control modes of foreside stands included conventional mass flow control and advanced mass flow control, and the three gauge control modes of rear stand included A, B and C. The application result indicates that the accuracy of thickness of product satisfies the requirement of the practical production with the combination of modes ad- vanced mass flow control of foreside stands and C of rear stand.
