| The project comes from Hefei Iron and Steel Company' s NO.3 blast furnace control system . Intrinsic control pattern of NO.3 blast furnace control system had more problems, as a result, they infected the control system functions. It used much more manpower and restricted the improvement of output and quality. The project of NO.3 blast furnace's control system uses up to the minute designed idea. Namely IE equipment integration, it makes maintenance easier and less equipments. As well as the lowness cost automated idea. Namely the level of basic automation use PLC method, the level of process automation use IPC, the design of monitor software use industry control configuration software.The task researches blast furnace's monitor system and blast furnace's control system design. In the time of designed the control system, we combine modern blast furnace's control technical and developing trend, as well as the enterprise's actual status. In the precondition of trailing the international modern technical, we preserved moderate advanced technique and fit our country status. Thereby it obtains the best percent of performance and price.All basic character of the control system as follows: The main technical electrical equipment, the instrument equipment and computer constitute the system of information unify and control disperse. Automation system use the class control, except the level of basic automated, it has the level of process automation. We build the real time database and history database of produce . Automation system creates the condition for improving produce technique. We designed the monitor interface . the interface can be easily understand, watched, resolved and manipulated. The control system has two level control system and two communication network. The method assures the system integrality, rationality.
