板形是热轧带钢的主要指标之一,精轧机板形控制是热轧自动化系统的关键技术。本文阐述了某热连轧厂基于CCTS的精轧机板形控制系统,介绍了板形控制的装置和方式,以及控制系统硬件设计和软件设计,详细分析了控制程序结构、APFC控制、弯辊控制和窜辊控制等主要控制,展示了HMI画面和主要功能,进行了数据采集和分析。投运以来,该控制系统运行可靠稳定,操作方便,热轧带钢的板形质量达到国内先进水平。 Strip shape is one of the main indicators of hot strip, strip mill shape control is the key technology of hot rolling automation system. This paper describes the CCTS-based finishing mill profile control system in a hot strip mill. The device and mode of the profile control, the hardware design and the software design of the control system are introduced. The control program structure, APFC control, bending roll control And channeling roller control and other major control, showing the HMI screen and the main functions of the data acquisition and analysis. Put into operation, the control system is reliable and stable operation, easy operation, hot strip shape quality reached the advanced domestic level.
