Abstract

There are virtually no published data on the combined effect of the impurities accompanying the dephosphorization process on the structural and physicochemical properties of iron melts. The state of the iron melt was considered as a function of composition and the corresponding values of density and surface tension based on the conditions of metal refining from phosphorus in the presence of manganese. The effect of these elements on the structural and physicochemical properties of melt was estimated according to the density and surface tension in the form of temperature and concentration dependence. In the manganese- and phosphorus-containing melts, compression effects and negative deviations from Raoult's law were observed. A decrease in the surface tension in the iron melts containing phosphorus and manganese was found. The addition of manganese to the iron melt had the opposite effect with respect to decreasing the surface tension and formation of the higher density.
