HOLDING FURNACE Russian patent published in 2012 - IPC F27B3/00 

FIELD: metallurgy.

SUBSTANCE: furnace includes at least one bath with side walls and bottom for arrangement of metal in it, and inductor of electromagnetic mixer, which contains magnetic conductor and at least two-phase winding and installed in the area of bath for application of electromagnetic field to the metal contained in the bath. Inductor winding consists of coils the active conductors of which are located relative to each other at the distance equal to Δx=l_x/(N-1), where l_x - length of the largest side of rectangular bath in which molten metal is contained, N - number of coils, which is determined as the number rounded to the nearest even integer of ratio l_x/h.

EFFECT: invention allows obtaining different structure of convective flows of molten metal depending on connection of coils located around magnetic conductor and providing effective mixing of molten metal with equalisation of its temperature and chemical composition.
