Abstract (en)

[origin: EP1302738A2] Electric arc furnace comprises a lower vessel (2); an upper vessel (3); and a waste gas bend (5) connected to a combustion chamber (7) or a stationary waste gas line via a flap valve (6), which can be adjusted to introduce air. The waste gas bend is formed on one side of the furnace vessel as a hood (5a) extending toward a suction opening (5b). A lid hole (4a) covers an electrode (10). <??>Preferred Features: The furnace lid (4) has no lining or has a reduced lining. A recess for the electrode is in the hood. The hood formed channel-like openings for introducing entrained air on its front sides.
