Abstract  An entire Level Ⅱ computer control system for 2 800 mm medium and heavy mill of LISCO was independently designed and developed. This system was composed by multiple modules, including data communication module, schedule setup module, self-learning module, rolling piece tracking module and data management module, etc. Data communication module took the responsibility of data exchange between Level Ⅱ control system and other systems. Data management module included data acquisition and data recording, which queried model parameters for model calculation and recorded actual technological process parameters of each piece. Rolling piece tracking module was in charge of position and data tracking of each piece in the whole process from heating furnace to rolling finished, and calling other functional modules at different trigger points to realize rolling pieces scheduling of auto steel rolling and rolling rhythm control. Schedule setup module made use of mathematic models to calculate rolling schedules. Self-learning module was divided into long term self-learning and short term self-learning. Based on the above modules, schedule auto setup and full automatic steel rolling control for rolling production process could be realized. This system had been successfully applied to the field of rolling production and the result was desirable.

Key words： medium and heavy plate      roughing and finishing mill      Level Ⅱ control system

柳钢中板双机架轧机Level Ⅱ控制系统开发

针对柳钢2 800 mm 双机架中厚板轧机,自主设计开发了完整的Level Ⅱ计算机控制系统。Level Ⅱ系统由数据通讯模块、模型设定模块、模型自学习模块、轧件跟踪模块、数据管理模块等多个模块组成。数据通讯模块负责Level Ⅱ控制系统和其他系统之间的数据通讯；数据管理模块包括数据采集与数据记录，为模型计算查询模型参数，记录每块轧件的实际工艺过程参数等；轧件跟踪模块负责轧件从出炉到轧制结束全过程位置和数据的跟踪，并在不同的触发点调用其他功能模块，进行自动轧钢的轧件调度控制和轧制节奏控制；模型设定模块利用数学模型，计算轧制规程；模型自学习模块包括长期自学习和短期自学习。通过各功能模块的协作,可以实现轧机生产过程的模型自动设定和全自动轧钢控制。该系统已经成功应用于生产现场，且应用效果良好。
