Abstract: In article questions of physical and chemical transformations of starting materials at their heating in metallurgical furnaces are considered. It first of all moisture evaporation, dissociation of the difficult connections, oxidizing and recovery processes, formation of fusible eutectics. An attention to interaction of oxides and sulfides with formation of the new connections having smaller melting point than initial components. It is shown that these connections are the beginning of formation of melts and actually define thermodynamics and kinetics of all process. Transition of firm components of fusion mixture to flux has a great influence on technological indicators of smelting of metal. Considering it, the research on establishment was conducted began courses of these of reaction and a possibility of determination of this criterion without direct the made experiments.
Keywords: Solid Fusion Mixture, Heating, Physical and Chemical Transformations, Moisture Evaporation, Dissociation of the Difficult Connections, Simple Components, Chemical Reactions, Fusible Eutectic, Fusion, Theoretical Definition, Beginning of Chemical Reactions.
