摘　　要： 针对中厚板轧机,研究了如何将设定计算功能嵌入过程控制系统,并应用于在线·将设定计算功能划分成轧制规程计算、轧机设定及控制参数计算以及模型自学习计算三个组成部分,分析了各部分的主要功能及其联系·设计了设定计算功能的在线数据流程和调用逻辑,根据具体轧线的检测仪表布置和生产工艺过程,多次调用设定计算功能·通过预设定计算、再设定计算、阶段前修正计算、道次修正计算、自学习计算以及待温时间修正计算,发挥设定计算及生产过程中实测数据的作用· How to function the parameter setup calculation in the process control system for plate rolling was studied. The parameter setup calculation was divided into three parts, i.e., rolling scheduling relevant mill setup and control parameters and model learning control, of which the main functions and relations among them were analyzed. The on-line data flow and calling logic of the setup calculation were designed. According to the arrangement of monitors/probes and scheduled rolling technological process, the setup calculation can be called time and again. By means of the presetting and resetting calculations including the modifications of different rolling phases and passes, learning control and holding time, the parameter setup calculation embedded in the process control system of plate mill has functioned as the on-line actual data during rolling.
