摘要： An electric arc furnace for melting scrap iron is to be of the simplest possible design while preventing thermal loads on the side walls caused by the electrodes and damage to the electrodes during charging. The electric arc furnace is distinguished by the combination of the following elements: a base (2) to take the melt (10); an upper part (13) projecting from the base (2) with a side wall (15); a lid (16) covering the upper part (13); a charging shaft (17) arranged approximately centrally to the upper part (13) with a considerably smaller diameter (21) than that (22) of the upper part (13). The inside (18) of the charging shaft (18) is connected to the inside (20) of the furnace by an aperture (19) in the lid (16) and there are electrodes (31) in approximately symmetrical radial array directed obliquely into the inside of the furnace projecting approximately towards the centre (14) of the electric arc furnace.

摘要： In a process for buring fuel (5) consisting of free hydrocarbons and/or solid fuel in fine-grained to dust form, to attain as eddy-free a mixture of oxygen and fuel as possible, several streams (13) of fuel are blown on curving path in relation to the central longitudinal axis (2) of a cylindrical or slightly conical main stream (14) of oxygen or oxygen-containing gas widening in the direction of flow, said streams (13) of fuel being formed peripherally to surround the main stream (14), penetrating thereinto and sucked into said main stream.

摘要： 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.
