发明名称 ARC TYPE STEEL-MAKING ELECTRIC FURNACE AND STEEL-MAKING PROCESS
摘要 <p>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). <IMAGE></p>
