Abstract
The present invention describes a device to cool ceiling (10) in electric arch furnaces, of the type comprising a plurality of contiguous panels (27) placed to cover at least a ceiling (10) internal circumferential periphery substantial part, each panel (27) consisting of at least a tube (11) wherein cooling fluid flow, ceiling (10) having at least a central aperture (35) for inserting, placing and moving electrodes (28), and at least a peripheral aperture or fourth orifice (16) to ventilate emanations from furnace interior, each cooled panel (27) covering its own arch defined of ceiling (10) internal circumferential ring, and comprising a spiral-shaped cooling tube (11), spiral windings (15) are located on respective vertical planes substantially radially placed with respect to ceiling (10) center, windings (15) defining a first external layer (17) and a second internal layer (18) of tubes (11), first external layer (17) and second external layer (18) being separated by a hollow space (19) which is located on a suitable plane for furnace ceiling (10) conformation, and works as an inlet ring (19) to circulate emanations and to direct them from furnace interior towards discharging aperture (16).
