Popis:	The concentration regions of the phase equilibria of the components in a metallic Fe–Mg–Al–Ca–C–O melt at a temperature of 1600°C have been calculated and built for low-, medium-, and high-carbon steels by simulating the solubility surfaces of the components in a metal. The conditions of formation of calcium aluminate inclusions in the system are determined. Carbon is shown to influence the sequence of phase formation with the participation of strong deoxidizers, such as calcium, magnesium, and aluminum. The liquid metal is found to contain composition regions in equilibrium with a gaseous CO-based phase or a gaseous phase based on calcium and magnesium vapors.
