Abstract

An arc furnace enclosure has front, side and rear walls and a roof. A front opening in the enclosure allows a charging bucket to be moved into the enclosure and there is a roof opening for access to the furnace electrodes. A door assembly is movable into and out of a closed position to cover the front and top openings except for a gap which permits the charging bucket support hooks to extend from the enclosure so that the door assembly may be closed during charging. An air curtain seals the roof gaps and a vent withdraws gases and smoke from the enclosure.
