基于中厚板轧制过程中头部厚度超差原因，分析了传统的头部补偿方法的不足之处。
Based on the cause of gauge oversizing of plate head, the traditional head gauge compensation methods were analyzed.
厚度控制系统特别是AGC系统对中厚板板形的开环控制有一定影响，特别是刚度偏小的轧机在轧制宽薄中厚板时容易出现边浪。
The gauge control system especial AGC system can deteriorate open loop control of plate shape especially when the mill rigidity is small, making edge wave of rolling plate.
