Metal and Casting of Ukraine| Резюме: | The experience of solving problems of optimization of metallurgical technologies using the methodology of physicochemical and mathematical modeling, the basic of which is developed by E.V. Pryhodko, is an original method of modeling of slag and metal melts based on the concept of directed chemical bond. The features of creation of information support system of theoretical and applied metallurgy on the basis of retrospective fund of experimental fundamental physicochemical data and fund of models of metallurgical systems and processes of their interaction at macro and micro levels are considered. Possibilities of original systematic mathematical support for creation of document-factual databases and applications of reliability estimation of "noisy" multidimensional arrays of physico-chemical and technological data based on modern methods of statistics and data visualization at different cross sections by purposeful design are described.
The principles of interaction between databases and model databases in the mode of mutual additionality are outlined. The choice of physicochemical criteria by "convolution" of information on the chemical composition of multicomponent iron ore materials, slag and metal melts is substantiated, and approaches to the prediction of their physicochemical properties according to the structure-structure-properties scheme are described. The problems of taking into account the influence of microinhomogeneity of the structure of metal melts on the formation of thermodynamic and thermophysical properties of ferroalloys and special alloys are considered. The methodology of creation of quality management systems of metal products and methods of multi-purpose optimization of metallurgical processes is proposed by constructing complex criteria of their efficiency indicators. An example of a blast furnace charge optimization problem is a generalized multi-purpose efficiency criterion that provides the required quality of melting products and its technical and economic indicators. |
