摘要
RH精炼炉是一种用于生产优质钢水的二次精炼工艺设备,现已成为炉外精炼设备的主流。根据企业管控一体化设计思想,针对RH精炼炉设备分散、现场环境复杂的特点,设计了一种基于工业以太网和Profibus现场总线的四级结构的电气控制系统:生产管理级、操作监控级、过程控制级和现场设备级。该系统综合运用了OPC和ODBC等接口技术实现各级系统之间的数据共享和工艺过程数据的存储管理。使用的PLC程序模块化设计方法便于工程化的管理,缩短了程序开发、调试的时间,使程序具有良好的可读性和扩展性。
RH refining furnace is used to produce molten steel of high quality as secondary refining equipment,and it＇s the mainstream of out-of-furnace refining equipment.Considering integration of management and control systems in enterprises,and the features of RH refining furnace,an electric control system,which has four layers：production management layer,operation monitoring layer,process control layer,field instrument layer,is designed based on Industrial Ethernet and Profibus.Data sharing among different layers and data management are realized through interface technologies such as OPC and ODBC.
