Abstract: In an electric arc furnace arrangement for producing steel by melting scrap (27), in particular scrap iron, and/or sponge iron and/or pig iron as well as additives in a furnace vessel (1), at least one graphite electrode (11), movable in its longitudinal direction, projects into the furnace vessel and an electric arc (26) is struck between the graphite electrode (11) and the charge (27). To achieve a particularly high energy input - the graphite electrode (11) projects into a lower part (8) of the furnace vessel (1) from the side and - in the region of the graphite electrode (11), the lower part (8) has a widened portion (8, 9) projecting radially outwards relative to the upper part (10) (Fig. 1).

Abstract: There is disclosed an electric arc furnace for the production of steel by melting scrap, in particular iron scrap, and/or sponge iron and/or pig iron as well as fluxes in a furnace vessel, into which at least one graphite electrode projects, which is displaceable in its longitudinal direction, wherein an electric arc is ignited between the graphite electrode and the charging stock. To achieve a particularly high energy input, the graphite electrode projects into a lower part of the furnace vessel from aside and the lower part, in the region of the graphite electrode, has an enlargement radially protruding outwardly relative to the upper part.
