    ENG: The technology of melting metals in an induction furnace allows the production of a wide range of alloyed steels to meet the different needs of society and is more environmentally friendly as it produces fewer emissions. A special interest for modern metallurgy are the processes of alloying and deoxidizing, which occur directly in the induction furnace by introducing lump additives. In this work, the investigation of the process of melting of additives during induction melting has been studied in order to determine the optimal modes of introduction of deoxidizing and alloying additives into the melt, providing their maximum assimilation by the liquid metal. The study was carried out on the physical model simulating the crucible of a laboratory induction furnace equipped with a closed system of hydrodynamic circulation of liquid. The results demonstrate that the most rational place for the introduction of ferroalloys into the induction furnace crucible is the area of the melt located at a distance of 1/2 radius from the center of the crucible. There is also a tendency for the dissolution time to decrease as the depth of introduction into the melt increases. Considering that in practical industrial conditions, it is extremely difficult to organize the introduction of deoxidizing and alloying agents into the volume of metal melt, the necessity of holding the melt when introducing ferroalloy is reasonable.
