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: In order to produce molten metal from all types of metal carriers used in metallurgy, and in particular from a wide range of quantitative combinations, an installation for producing molten metal comprises the following components: an electric arc furnace (1) having a charge opening (11, 21) for molten metal and/or scrap and/or directly-reduced metal, especially directly-reduced iron and/or ore, and at least one electrode (16) and a slag tapping unit (22); and an oxygen lancing converter vessel (3) fitted with a slag tapping unit (41). Said oxygen lancing converter vessel (3) forms a single unit with the electric arc furnace (1) which unit is connected by means of an overflow weir (34) and rigidly mounted on the base. The bath surface specifically related to bath volume is smaller in the oxygen lancing converter vessel (3) than in the electric arc furnace (1). Lastly, the oxygen lancing converter vessel (3) shares a common reaction chamber with the electric arc furnace (1), which chamber is situated above the bath level of the two vessels.

Abstract: A plant for the production of molten metals, includes a melting vessel and a metallurgical vessel receiving the melt from the melting vessel for aftertreating the melt and closed by a lid. The melting vessel has a tap opening for the melt provided on the bottom level of the melting vessel and located on the periphery of the melting vessel. The tap opening is positioned above a pour-in opening of the metallurgical vessel. In order to ensure a continuous melting procedure, the pour-in opening of the metallurgical vessel following the melting vessel is provided above a melt guiding chute arranged within the metallurgical vessel.

Abstract: There are disclosed a method and an arrangement for preventing the agglomeration of crusts in a lance opening passing a wall of a metallurgical vessel and provided for a lance carrying a measuring and/or sampling probe. During the metallurgical process proceeding within the metallurgical vessel and during the taking of a measurement and/or sample by means of a lance introduced into the metallurgical vessel through the lance opening, a gas that is inert relative to a melt bath contained in the metallurgical vessel, or air, is injected into the lance opening from outside, which gas produces a gas veil at the mouth of the lance opening facing the melt bath.
