“…However, because of very complicated characteristics of the present liquid-solid-gas systems, computational thermochemical software, FactSage TM 6.1 was employed to calculate the equilibrium composition of slag and gas phases at 1600 • C. [21][22][23][24] Here, the FToxid and Fact53 databases were used. This package and databases have been successfully employed to evaluate the slag/refractory interfacial reactions.…”

“…In particular, the Al 2 O 3 -CaO-MnO-SiO 2 system has been optimized. [21][22][23] This system is of interest for inclusion control in Mn/Sikilled steel as will be discussed in more detail in the following sections. The phase equilibria in this quaternary system are illustrated in Fig.…”

Computerized thermodynamic databases for solid and liquid metals, slag, and solid oxide phases in the Al 2 O 3 -CaO-CoO-CrO-Cr 2 O 3 -FeO-Fe 2 O 3 -MgO-MnO-NiO-SiO 2 system (with dissolved S and P) have been developed by critical evaluation/optimization of various available phase equilibrium and thermodynamic data. The databases contain parameters of models specifically developed for molten slags, liquid steel, and solid oxide solutions such as spinel, pyroxenes, olivine, monoxide (wustite, periclase, lime), corundum, etc. By means of the optimization process, model parameters are found which reproduce various thermodynamic and phase equilibrium data within experimental error limits. Furthermore, the models permit extrapolation into regions of temperature and composition where data are not available. The databases are automatically accessed by user-friendly software that calculates complex equilibria involving slag, metals, refractories, and gases simultaneously, for systems with many components, over wide ranges of temperature, oxygen potential, and pressure. A short review of the available databases is presented. The critical evaluation/optimization procedure is outlined using the Al 2 O 3 -CaO-FeO-Fe 2 O 3 -MgO-SiO 2 and Al 2 O 3 -CaO-MnO-SiO 2 systems as examples. Several applications of the databases to deoxidation, dehydrogenation, and dephosphorization of iron and to inclusion control in steel are discussed.
