AGC技术是现代热连轧机的关键技术之一,其控制效果直接影响到成品的质量和精度.结合在某钢厂600 mm九机架热连轧精轧机上的应用,介绍了Dynamic Setting AGC (DAGC)控制系统的原理,给出了DAGC控制系统结构,分析了轧件塑性系数对辊缝调节量的影响.实际应用证明,DAGC系统控制效果明显,带钢厚度偏差均可控制在±40μm之内.%AGC technology is one of the key technologies of modern hot strip mill. Its control effect directly affects the products' quality and accuracy. In combination with application of a 600 mm nine-stand hot strip finishing mill, the principle of DAGC is introduced and the structure of DAGC control system is given. The influence the plastic coefficient of rolled pieces on roll gap's regulating-variable is analyzed. The practical application proves that control effect of DAGC system is obvious, and the strip thickness deviation can be controlled within ± 40 μm.
