摘　　要：厚度控制是厚板轧制的关键技术,涉及到同板差和异板差两大评价指标。从轧制模型和AGC控制技术着手,提出一套高精度厚度控制策略和方法,运用于江西九钢中厚板生产线在线轧制控制。实践表明,该技术功能完善,精度高,对钢板厚度控制有很好的效果。Thickness control is the key technology of heavy plate rolling,which involves two evaluation indexes of the setup accuracy and the inbar accuracy.Starting from the rolling model and AGC control technology,this paper puts forward a set of high-precision thickness control strategies and methods,which are applied to the on-line rolling control of PXSteel medium plate plant.The practice shows that the technology has perfect function,high precision and good effect on steel plate thickness control.
