Abstract

An electrode assembly for an electric arc furnace incorporates a water cooled sleeve (24) which extends downwardly from an electrode clamp (18) around a portion of a consumable electrode (14) held by the clamp. During normal electrode movement, the sleeve is preferably telescopically received within, but spaced from, a water cooled annulus (34) defining an opening in a furnace roof. A sliding seal (40, 42) is provided acting between the sleeve and the annulus, of a form which allows the sleeve to be lifted upwardly out of and re-inserted into engagement with the annulus. The annulus may be extended vertically to shroud the sleeve.
