ELECTROMAGNETIC CRUCIBLE MELTING FURNACE WITH HORIZONTAL MAGNETIC CIRCUIT AND MAGNETIC FLUX Russian patent published in 2015 - IPC F27B14/06 F27D11/12 F27D27/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and to foundry production, namely to design features of electromagnetic induction crucible furnaces for melting of cast metals and alloys. A furnace includes a housing, a crucible with a bath, a magnetic circuit with opposite poles, which is made as an integral part of the housing and located horizontally around the crucible, two inductors with coils enveloping the magnetic circuit are installed between the poles at two opposite sides of the crucible and opposite connected; poles of the magnetic circuit, which create horizontal magnetic flux, face to each other and to two other opposite sides of the crucible. The magnetic circuit has an O shape.

EFFECT: invention allows reducing losses due to wear of a crucible and defects of casts as to non-metallic inclusions and energy consumption of the melting process, reducing overall dimensions of the unit, as well as increasing safety and reliability of an induction crucible furnace.
