ABSTRACT:
An electric arc melting furnace for metal has a roof liftably positioned on a funnel-shaped refractory mouth portion, has conventional electrode openings therethrough, and provides for a smoke hole through which fumes may be exhausted. A cooling fluid-receiving circulating metal duct is positioned to extend along and in a somewhat supporting relation with respect to an outer periphery of the funnel-shaped mouth portion for introducing cooling fluid into J-shaped, heat chambers that are positioned in a circumferentially spaced relation within and about a refractory side wall in such a manner as to provide for a maximum cooling action adjacent a sill area of the furnace. Cooling-fluid-receiving and circulating chambers in the side wall are, in effect, closed or sealed-off with respect to each other. Warmed fluid or air exhausting from the chambers in the side wall may be used for heating cooler areas inside the furnace, for outside furnace discharge for room heating, etc., or may be employed for supplying air to burners located about the furnace to heat colder areas therewithin.
