FIELD: mechanic engineering.
SUBSTANCE: invention relates to equipment for high heat oxidation material production. Electric arc furnace includes water-cooled enclosure and cove provided with holes for electrodes and for feed stock loading, taphole for molten mass discharge and gas vent. Novelty is that gas vent represented with holes describing enclosure perimeter on the level of cove. Holes are combined into collector being outside enclosure and connecting to dust-exhaust system of furnace. Enclosure is not brick lined, thus ensuring gas cooling to 150-185°C and aspiration by sleeve filters.
EFFECT: decrease of temperature and dust content in removed furnace gas.
