首钢中厚板轧机过程控制系统

针对首钢新建3500mm中厚板轧机,自主设计开发了完整的两级计算机控制系统·在过程控制系统中包括了数据通讯、数据管理、过程跟踪和模型计算等主要功能·数据通讯模块负责过程控制系统和其他系统的数据通讯;数据管理模块负责数据库的读写,为模型计算查询模型参数,记录每块轧机的实际工艺过程参数等;过程跟踪模块负责轧件加工过程位置和数据跟踪,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;模型计算模块利用数学模型,进行轧机的轧制规程计算和控冷系统的控制参数计算·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·该系统已经在现场成功使用·

Process Control System for Plate Mill in Shougang

A two-level process control system was developed independently and applied to the 3 500 mm plate mill in Shougang in Beijing. Covering such functional modules for data communication, management, process tracking and model computation, they are used correspondingly for data communication among the process control system and other system; database reading/writing, model parameter querying for computation and actual process parameter recording for each and every workpiece, position/data tracking for workpieces to actuate other functional models at different points so as to control/schedule all workpieces automatically, and model computing for pass schedule and cooling system control. With those modules working collaboratively, a model-adaptive and fully automatic rolling control is available, which has been used in site successfully.
