ELECTRIC FURNACE

WIPO Patent Application WO/2023/234499

A1

The present invention relates to an electric furnace having double melting furnaces. The electric furnace may comprise: a first upper cell forming a first upper space of a first melting furnace in which a first iron source is inputted and dissolved; a second upper cell forming a second upper space of a second melting furnace in which a second iron source is inputted and dissolved; a lower cell coupled to the lower portions of the first upper cell and the second upper cell so as to enable a first lower space of the first melting furnace and a second lower space of the second melting furnace to be formed into one integrated space; and a partition unit installed between the first upper cell and the second upper cell so as to be vertically movable, thereby separating the first lower space of the first melting furnace and the second lower space of the second melting furnace which are formed so as to be integrated by means of the lower cell.
