E., D.Sc. (Engineering), Professor, e-mail: levshing@mail.ru I.I. Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation Abstract The results of theoretical and experimental study of electrical and thermal parameters of an electromagnetic induction melting crucible furnace with a curved U-shaped magnetic circuit and a frequency of 50 Hz are presented. Based on these results a furnace was made which induces a horizontal magnetic flux between the two poles of the magnetic circuit acting on the crucible. A possibility of rapid melting of simulina and brass in the laboratory furnace and the need for cooling an electric coil is shown. The results obtained will help to create a method for the design and calculation of basic electrical, magnetic and thermal properties of electromagnetic furnaces of various sizes.
