Abstract
Induction smelting crucible furnaces have the advantage of optimal management of the process, regulation of the capacity and have high technical indices. The research of electrical and energetic correlation of induction smelting crucible furnaces is necessary in order to analyze the work and elucidate the optimal condition of exploitation, to work out the methods of projection and determine the optimal constructions of magnet wires. The authors worked out the methods of calculating the energy of electromagnetic field according to the sections of the space of the induction system, to the selection and installation of magnet wires in order to meet the technological requirements in the best way and to achieve high energetic and exploitation indices when building the induction crucible furnaces. The work represents the influence and interrelation of the inductor and the charge with the magnet wire depending on geometrical correlation of the induction system.
