INDUCTION CRUCIBLE FURNACE WITH AN ASSEMBLED ANNULAR MAGNETIC CORE Russian patent published in 2018 - IPC F27B14/06 F27D11/12 F27D27/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular to an induction crucible furnace with an assembled annular magnetic core, which is intended for using in metallurgy and foundry production for the smelting of various alloys. Furnace comprises connected lined crucible, bottom, cooled inductor with electrically insulated windings and current lead, covering its outer vertical assembled magnetic core and frame with upper and lower plates fastened by ties. Wherein it is provided with a cylindrical shell placed between the crucible and the inductor, and said magnetic core is made in the form of an annular casing, wherein the shell and the magnetic core are placed between the plates to form a closed, sealed annular cavity for accommodating the inductor and the coolant, with the possibility of supply and discharge.

EFFECT: invention provides significantly wider scope of use of said furnace by reducing the energy intensity of the smelting, reducing the operating costs and occupied area, increasing the inductor protection and furnace operation reliability.
