    摘要： A lance for top injection of a fluid in metallurgical vessels comprises an inner tube, a refractory sheath surrounding the inner tube, an anchoring point rigidly coupled to said inner tube and at least partially embedded in the refractory sheath, an annular gap separating the inner tube from the refractory sheath; at least one annular guide surrounding the inner tube and comprising: an annular portion circumscribing the inner tube, and at least two anchor protrusions rigidly extending transversally from the annular portion and at least partially embedded in the refractory sheath, wherein a guide gap is formed between the annular portion and an outer surface of the inner tube. The at least two anchor protrusions are distributed over the external surface of the annular portion, separated from one another by an angle comprised between 90° and 270°.

    摘要： The invention relates to a method for operating a blower lance arrangement, in which method hot blast is blown onto the melt bath and/or the bulk material bed in a converter, wherein the hot blast lance is fed via a hot blast line from a hot blast source, according to the preamble of claims 1 and 8. In order to achieve a more effective blowing method and to improve the blower lance in terms of the coupling with the hot blast source, according to the invention the hot blast lance is detachably connected to the hot blast source in such a manner that the connection can be automatically detached and reconnected for each batch, i.e. between the batches.

    摘要： The invention relates to a method for operating an electric arc furnace (1), wherein molten material (3), in particular steel, located in a hearth vessel (2) is heated by at least one arc (4), wherein a cover (5) is arranged on the hearth vessel (2), wherein the electric arc furnace (1) is provided with an outlet opening (7) in at least one location (6), through which outlet opening furnace exhaust gases are led out from the interior of the furnace and supplied to a dust removal system (8), and wherein an oxygen-containing gas (G) is led into the interior of the furnace for post-combustion. In order to achieve an improved post-combustion in the furnace, according to the invention the oxygen-containing gas (G) is led through an inlet opening (9) that is spaced apart from the outlet opening (7), and the oxygen-containing gas (G) is allowed to flow into the interior of the furnace by means of at least one input element (11), wherein the at least one input element (11) is arranged radially oriented in the wall (10) of the hearth vessel (2), or wherein the at least one input element (11) is arranged oriented towards the center of the furnace in the wall (10) of the hearth vessel (2), wherein the outlet direction (S) of the input element (11) encloses a small angle (α) in the downward direction with respect to the horizontal.
