Definitions

  • the invention relates to a method for the metallurgical treatment of Ferrous metals, in particular for the production of molten steel, and a associated steelworks facility with at least one metallurgical vessel, which can be closed by a swiveling cover which can be closed by a Flue gas manifold communicates with and through a gas cleaning system whose lid heart can be guided at least one electrode, and a device for Filling the vessel with batched goods as well as a slag removal and one in Bottom of the vessel arranged melt tap opening.
  • the main hood is independent of the metallic vessel arranged ceiling connected, with which they can be moved to the side as a unit is designed.
  • Electric arc furnaces are usually operated with direct current or with alternating current besides.
  • a double furnace device is included
  • Two-furnace vessels and a method for operating this device are known can be closed by a cover, which is connected to a flue gas manifold Gas cleaning system are connected.
  • a cover which is connected to a flue gas manifold Gas cleaning system are connected.
  • Both furnaces are operated in such a way that one furnace for melting the batch contained therein is supplied with electrical energy and the other is completely disconnected from the electrical network and after charging with the warm flue gases from the other furnace. It is metallurgical this is a one-step process.
  • Metallurgical vessels have also been proposed. So is from the DE34 19 030 C1 a metallurgical reaction vessel, in particular a Steel mill converter, known for each process stage of a process and for operating devices arranged above and / or below the reaction vessel corresponding functional part can be rotated about a vertical axis of rotation is achievable. To the operating facilities pay z. B. exhaust pipe, Charging device, measuring lance, blowing lance and bottom descent device. These are permanently installed, while the reaction vessel is in the corresponding position is rotated.
  • the reaction vessel is each suitable for one method. It is used for production of metal melts, in particular steel melts, and the production of gases such as B. of CO gases from coal and a substance by its presence Supported reaction and used up little or not at all, how e.g. B. of pig iron melting.
  • the aim of the invention is to provide a method and a device suitable therefor create with the energy-saving, environmentally friendly and inexpensive metallurgical work of ferrous metals, in particular for the production of Melting steel, is feasible.
  • all metallurgical work is done in one vessel carried out, this vessel once the function of a converter and immediately afterwards without transferring the melt product the function of a Arc furnace takes over.
  • This can be done in a particularly advantageous manner Process in two metallurgical overlaps of 50% in their work cycles Design vessels.
  • the exhaust gases are extracted during the reduction work. After inflation is complete, the phosphorus-containing slag is slagged off. At this point, an exchange of operating equipment is carried out, namely the lance and the exhaust manifold are removed, instead the electrodes are inserted and the flue gas line is opened in order to then carry out the melting work via the electric arc furnace. At the end of the process, the residual slag is slagged off and the liquid melt is tapped off at the bottom.
  • the bottom cut is cleaned and closed again, the corresponding material is charged, the lid of the furnace vessel is closed, the lance or burner and the exhaust manifold are brought into position and the process can be started again.
  • a melting process takes place using electrodes in the other furnace vessel. These flue gases are passed through a flue gas manifold into a mixing chamber, where they mix with the exhaust gases from the blowing process. Since the blowing process allows very high flue gas temperatures due to afterburning the CO, this ensures that possibly colder flue gases from the electric furnace operation are safely re-burned. This reliably prevents possible odor nuisance and possibly other hydrocarbon compounds such as furans and dioxins.
  • a steel mill device with a metallurgical vessel in which lids are used, the lid hearts of which can be removed.
  • the mouth of an exhaust manifold is placed on the lid heart opening, through this manifold and the opening in the lid at least one lance or at least one burner is brought into the interior of the upper part of the metallurgical vessel.
  • the metallurgical vessel can be converted from an electric arc furnace to a converter in a few simple steps and with extremely simple design.
  • the lance guided through the exhaust manifold is connected to a moving device which, as can be predetermined, immerses the lance head deep into the vessel.
  • the lance used can be designed as a pure oxygen lance, as a pure burner, but also as a multifunctional lance.
  • the flue gas manifold which is customary for the electric arc furnace, has shut-off devices which are closed by the exhaust manifold during the blowing phase and suction.
  • the pivot points of the electrode pivoting device and the rotating device of the Exhaust manifolds are also in an electric furnace system with only one furnace vessel on one Dividing line arranged that exactly the first furnace vessel from the second (Expansion) oven vessel separates.
  • FIG. 1 shows the top view of a single furnace system with the possibility of expanding it as a double furnace system.
  • the lid 13 (23) attached to the lid pivoting device 14 (24) can be seen in the swung-out and in the operating position.
  • the lid heart 25 can also be clearly seen.
  • Flue gas manifolds 51 (52) are connected to the covers 13 (23) and are connected to a main flue gas pipe 55 via a shut-off valve 53 (54).
  • the suction 56 (57) of the bulges 18 (28) are connected to the flue gas main line 52.
  • the lid 13 is detachably connected to an exhaust manifold 61, which has a Rotating device 63 is pivotable.
  • the flue gas main 55 and one Exhaust main line 64 are brought together in an afterburning chamber 71.
  • a lance 41 is guided through the exhaust manifold 61 and is carried by a lance support arm 42 is held.
  • Electrode 31 is guided through the cover heart 25 and is connected via a Electrode support arm 32 is connected to an electrode pivoting device 33.
  • FIG. 2 shows schematically the two operating states, namely the metallurgical vessel in the function of a converter and the other as an arc furnace.
  • a lance 41 is fastened to a lance support arm 42 and is guided coaxially to the main axis I of the vessel through an exhaust manifold 61 and the heart opening 16 into the interior of the upper part 12 of the vessel.
  • the upper part 12 and the lower part 17 together form the furnace vessel 11, which is closed by a lid 13.
  • the lid 13 has a lid heart opening 16, against which the mouth 62 of the exhaust manifold 61 rests.
  • the exhaust manifold 61 is pivotable via a rotating device 63.
  • the lower vessel 17 has a tap opening 19, in this case the bottom tap, for the metal workers.
  • the furnace shown in the left half of the figure shows an electrode arm 32, to which three electrodes 31 are attached in the present case, which are guided through the cover heart 25, which closes the cover heart opening 26.
