Systems and methods of electromagnetic influence on electroconducting continuum
View Patent ↗Thus, as shown by an exact electrodynamic computation of EMBF and the estimations described above of the velocity of turbulent flows arising due to their effect, application of amplitude- and frequency-modulated helically traveling (rotating and axially traveling) electromagnetic fields in metallurgical and chemical technologies and foundry can considerably increase the hydraulic efficiency of MHD facilities, intensify the processes of heat and mass transfer in technological plants, significantly increase their productivity, considerably decrease energy consumption for the production of metals, alloys, cast articles, and chemical products, and improve their quality.
1. A melting chamber of an electric-arc furnace comprising:
a jacket;
a lined cylindrical part;
a floor and a roof, the floor having a lining;
wherein a rotating magnetic field inductor is arranged in the floor lining with a magnetic circuit of the inductor being made of a ferroceramic with a high Curie temperature and wherein coils of the inductor are made in the form of ceramic boxes filled with a metal whose melting temperature is lower, and boiling temperature higher than the melting temperature of molten material in the furnace.
