The model of control the converter process in the decision-making system
Abstract
The principle of constructing a model of relatively static and dynamics control of the oxygen-converter process is shown. The models of heating materials, the model of calculation the bulk for the melting using the final slag and dynamic control (control of the metal mass, the rate of decarburization, slag formation, the model of determination the feasibility and the moment of the slag folding, a dynamic model of melting futher blow). Analyzed the results of industrial tests of the model. The motion pictures (examples) of the control model implementation are shown: video picture "calculation of metal part of the shaft", video picture "recommendations on the melting control" video picture "further blowing". The results of industrial tests of models, which were per-formed for the data of the control of the 350-ton Converter JSC Metallurgical combine "Azovstal", were analized. It showed an increase in the effectiveness of converters work on key indicators: increase in yield casting, lining resis-tance, an increase in the number of controlled meltings.References
