Calculation-Experimental Method of Manganese Losses

Three tasks have been consistently solved in this paper. A thermodynamic analysis of the high-carbon ferromanganese smelting was carried out. The associated solutions theory was used to describe a thermodynamic activity of components in the metal and slag. Comparison of the calculated and technological data shows that the melting ends in conditions close to chemical equilibrium.
