In this paper, Pan Gang 1 # blast furnace overhaul as the background, blast furnace three control modes of study and discussion, the main task is how to form the three blast furnace control system, how the system design, function how to achieve and conduct a study on trends and other issues. First of all, through the introduction of the blast furnace process, analysis of the blast furnace process and its characteristics, the blast furnace production model, and some research and discussion, as well as the function of each model illustrates. According to the control theory point of view, the basic idea of ??the blast furnace control, according to the basic idea of ??the hierarchical structure of the blast furnace control system extremely functional discussed the formation of the basic automation system of blast furnace, blast furnace process control systems, blast furnace production management system based on the three blast furnace control mode. Blast furnace basic automation system to Westinghouse Ovation distributed control system, for example, blast furnace process control system to the VAI VAIRON expert system as an example, blast furnace production management system to LTMIS the system as the basis for the study and exploration work. OVATION system, for example, discussed the basic automation system engineering problems to be considered, the structure and characteristics of the basic automation system, system software and hardware components, combined with the engineering design for various functions realization were discussed, made a certain part of the control algorithm and its application in the blast furnace production process. Furthermore, the Case of VAIRON expert system, discussed the development and significance of the blast furnace expert system expert system for the basic structure and design steps design ideas, explore the characteristics of blast furnace expert system analysis of blast furnace expert system optimize the target of the operation of the expert system to participate in the blast furnace control processes, mode of operation, data processing and the role of the study and discussion of the expert system control functions to achieve. Then, to LTMIS system as an example, the production LAN design steps, design guidelines and design principles, based on the comparison to determine the system network architecture as well as the physical and logical topology; determine the system's communication protocol of communication protocol . Network software system design, including: system software, user functionality and dynamic data acquisition applications such as software design, combined with the network security technology and the actual plant, developed a network security control system. Finally, CIMS, blast furnace model, the blast furnace detection technology, diagnostic techniques, intelligent control technology five blast furnace control technology development, research and outlook.
