The thermodynamic-diagram analysis method has proven to be a valuable tool in the realm of complex theoretical research of multi-component systems. This method simplifies the study of phase transformations in multicomponent systems by breaking them down into thermodynamically stable elementary partial subsystems of equal dimensionality as the main ones. The practical implications of this approach, as evidenced by studies in the field of refractories and ferroalloys production, are significant. It aids in interpreting chemical interactions in complex systems, thereby contributing to the development and optimisation of manufacturing processes. Technological research was carried out in an ore-thermal furnace with a capacity of 150 kVA. As a result of the study, quantitative data were obtained on the ratio of components of complex alloys with an average content, %: Mn – 26-50; Si – 30-48; Al – 2-3; Fe – 15-21.
