Patent abstract
A slag discharge door apparatus for an electric furnace is disclosed. The apparatus includes a door which is operated by a door operator to open or close a slag discharge outlet of the electric furnace, and a door support which supports the door in such a way that a portion of a lower end of the door overlaps with the door support, so that slag is inhibited from leaking out of the electric furnace through the slag discharge outlet.
