ABSTRACT OF THE DISCLOSURE For use with an electric arc melting furnace having a crucible and an upwardly directed mouth covered by a roof, and a device coupled to the roof for projecting it upwardly along an axis and pivotally about the axis to a position out of registry with the mouth for providing access for charging the furnace, and a device for tilting the furnace for tapping and slagging, a fumes exhaust system comprising an exhaust fan, a telescoping main fumes exhaust duct flexibly coupled at one end to the exhaust fan, a coupler flexibly connected to the other end of the main fumes exhaust duct and a tapping and melting manifold and hood flexibly and telescopically connected to the coupler. The tapping and melting manifold and hood are connected to the roof and project vertically along the roof axis and pivot about the roof axis with the roof to a position out of registry with the mouth. A slagging manifold and hood are mounted on the furnace and connected to the coupler. The fumes exhaust system includes a charging hood adapted for movement into close, overlying relationship with the furnace mouth when the tapping and melting manifold and hood axe withdrawn from registry therewith, the charging hood having an opening in its top through which the charging bucket is lowered, the charging hood being in communication with the slagging manifold when the charging hood is in overlying relationship with the furnace mouth. The charging hood is constructed to provide or air movement past the mouth and into the slagging manifold for exhausting fumes and dust evolved during charging of the furnace into the main fumes exhaust duct.
