ANALITICAL AND EXPERIMENTAL STUDIES OF PROPERTIES OF SLAG AND SLAG-FORMING MIXTURES OF STEEL MAKING PRODUCTION<\/strong><\/strong><\/p>\n\n\n\n

Abstract. <\/strong>The aim of the study is to analyze and generalize the properties of slags within the CaO-SiO2<\/sub>-Al2<\/sub>O3<\/sub>-MgO-CaF2<\/sub> system in different ratios of components and their concentrations, which is the basis of refining slags in modern steelmaking. To ensure the technological functions, the slag melt should have a set of optimal values of physical and chemical properties, in particular: viscosity, surface tension, electrical conductivity, melting temperature (beginning and end), enthalpy, density and others, which significantly affect the kinetics of heat and mass transfer processes in the “metal-slag” system. The information resource of researches is provided by own experimental data and data of databases “Slag” and “SFM” containing information about technological properties of melts of slag and oxide systems. The analysis of the data on the dependence of the properties of oxide systems on their chemical composition and temperature was performed. Oxide systems within the chemical composition CaO-SiO2<\/sub>-Al2<\/sub>O3<\/sub>-MgO-CaF2<\/sub> are considered. The connection of the chemical composition of slag systems with the properties of their melts from the point of view of the concept of directed chemical bonding using integral parameters is established: \u03c1 is the stoichiometry index; \u2206e is the average number of electrons localized in the direction of the cation-anion (K-A) bond; d is the average inter-nuclear distance K-A; tg\u03b1 is the change in the electron density in the direction of the K-A bond; ZA(A-A)<\/sub>, ZK(K-A)<\/sub>, ZK(K-K)<\/sub> are the weighted average values of cation and anion charges in the A-A, K-A, K-K bonds. Based on the results of experimental and analytical studies, predictive models of the properties of the considered oxide systems were obtained, namely for the calculation of viscosity, electrical conductivity, crystallization temperature and density of slag melts in the range of their temperatures from 1200\u00b0C to 1800\u00b0C. The presented method of predicting the properties of refining slags can be used to evaluate the use of slags of different composition in the ladle, for example, in ladle-furnace installations.<\/p>\n\n\n\n
