FURNACE PLANT Russian patent published in 2000 - IPC

FIELD: furnace plants for melting-down and holding of melt of metal, in particular, aluminium. SUBSTANCE: the furnace plant has at least one furnace tank with lateral walls and bottom, and at least one heat source for heating of the molten metal and/or hard metal placed in the tank by radiation and convection. Installed in the tank wall or near it is at least one lateral two-phase or multi-phase electromagnetic agitator for field application to molten metal through this wall. The lateral agitator has at least two phase windings located around an iron care, whose vertical extent H essentially overlaps zone Dmax between the bottom and upper surface of molten metal at a maximum depth of the bath used in the furnace tank. The lateral agitator is made with pole pitch τ twice exceeding the distance from the iron care to molten metal, i.e. τ > 2d_w. EFFECT: reduced loss of metal and enhanced power utilization factor and furnace capacitance. 8 cl, 3 dwg
