| Vice gun detection is a very important process in the steelmaking process, for itsefficiency is related to the economic benefits of the entire steel mills. The study objectof this paper is vice gun system in Anshan Iron and Steelmaking general factory,mainly analyzing the steelmaking process, the working principle of the sub-gun systemand related technologies of modern automated theory. On the basic of steel-makingprocess ‘s analysis and the working principle of the sub-gun.the parameters of thesub-gun vertical speed control given, and the entire converter system is decomposedinto multiple control subsystem. Meanwhile, according to the characteristics andcorrelation of the control loop, we select the fuzzy control of complex circuits, andestablish a dynamic monitoring interface in the PC. Applly the above controlscheme,and we’ll use the hardware resources rationally, save the cost of engineeringconstruction investment and system operation, Improve the operating systemvisualization capabilities of vice gun converter automation in the steel-making system.Through its host computer operation. we you can complete the real-time display of thevice gun control parameters and settings, automatically switching between manual andvice gun system start and stop operations. According to the analysis of influencingfactors on the vice gun system action, the fuzzy control scheme of the sub-gun liftingsystem is designed. Complete the process and data collection storage based on theS7-400programmable controller. The actual production application of this program vicegun vertical speed and testing the depth of control have a better system stability,responsiveness and accuracy. The research and development of this system can hasexpanded the fuzzy control applications, opened a new one for modern control theory,provided a strong technical support and valuable experience.for automated steelmakingintelligence, information inAnshan Iron and steel-making plant The optimized Sublancesystem get a better validation in the actual production run of the Steelmaking Plant. |
