摘要
An electric arc furnace includes a substantially cylindrically configured melting vessel having an upper shell defining a top opening. A water-cooled roof assembly is supported by the upper shell and positioned over the top opening and can be removed from the top opening for permitting the charging of scrap into the melting vessel. The water- cooled roof assembly includes an annular configured, water-cooled outer roof panel defining a central opening. An annular configured, water- cooled inner roof panel is positioned within the central opening of the outer roof panel and is removably mounted on the outer roof panel. The inner roof panel includes a central opening that removably mounts a central refractory. At least one electrode is mounted in the central refractory and extends into the melting vessel.
