Abstract

The invention relates to metallurgy and can be used in gas flue section of electric arc furnace. A flue has afterburning chamber, dust sedimentation chamber, cooled gas duct and inlet nozzle. It is connected to afterburning chamber and is equipped with movable drive sleeve for connection to roof nozzle of electric arc furnace with possibility of dozed suction of fresh air. At that inlet nozzle is inclined at angle 40-50° to horizon to side of connection to the roof nozzle. Area of its cross section is 1.02-1.12 times larger than area of cross section of the roof nozzle. To remove scar after end of melting the sleeve is shifted up. Cold air quickly cools the scar, it is cracked due to thermal stresses, detaches from surface of inlet nozzle and poured by inclined surface thereof without additional forces. The invention promotes decrease of losses for purification of receiving branch pipe with removal of scar.
