Definitions
- the invention relates to a metallurgical vessel having a cavity for treating a first liquid metal or for liquefying a metal, the vessel comprising a coolable wall with a hot side facing the cavity and a cold side facing away from the cavity made of a second metal, and wherein optical fibers for Collection of data of the metallurgical vessel or the first metal are introduced into the wall of the vessel.
- the first metal is especially steel, but it may also be another metal.
- the second metal is in particular copper, although it is also possible to provide another metal.
- the invention further relates to a method for producing a wall for the metallurgical vessel and the use of optical waveguides in the wall of the vessel.
- optical fibers As sensors optical fibers are used, is passed through the laser light. On the outside of the copper plates grooves are formed, in which the optical fibers are laid.
- the temperature detection by means of optical fibers allows a significantly lower cable costs than the use of thermocouples in the mold. In addition, considerably less labor and expense is required to install the fibers in the mold copper plate.
- the use of the optical waveguides also allows a higher spatial resolution, as they can be achieved when using thermocouples, which are used in drilling. An optical fiber can replace more than a hundred thermocouples and their cables.
- the optical waveguides are, for example meandering between the cooling channels on the back, d. H. on the cold side, a copper plate of a mold laid in grooves.
- the optical waveguides can be cast in the grooves by means of cast resin. Closure by other components or by electroplated layers is also known.
- DE 1 0 2008 006 965 A1 discloses a method for determining a radiation measure for a thermal radiation emanating from an arc burning between an electrode and melted material in an arc furnace for the production of liquid metal, generally steel, which is then used for Use comes when the radiation is limited to a limitation of the arc oven hits.
- liquid metal produced from a solid melt such as scrap or reduced iron
- energy for melting the melt is introduced into the arc furnace by means of one or more electrodes, usually in the form of an arc between the electrode and the melt.
- the melting attempts are made to introduce as much as possible of the total energy provided by the arc into the melt.
- Melted material is to be understood as melting solid, liquid metal and / or also slag.
- an electrode current supplied to the electrode is detected, whereby structure-borne sound oscillations of the arc furnace are detected and a current evaluation signal assigned to a frequency range of the detected electrode current is determined from the detected electrode current, wherein a vibration test results from the recorded structure-borne sound vibrations.
- evaluation signal is determined, which is associated with a frequency range of the structure-borne sound vibrations.
- a quotient of the vibration evaluation signal and the current evaluation signal for at least one detected frequency of the detected electrode current and the detected structure-borne sound vibrations is formed as a measure of the thermal oscillation in order to determine the radiation measurement.
- this object is achieved in that the optical waveguides are arranged near the surface in the region of the hot side.
- metallurgical vessel for the purposes of the present invention includes all types of metallurgical vessels, including furnaces, in particular E- lektrolichtbogenöfen, and molds, in particular for continuous casting.
- wall in the sense of the present invention also includes individual wall elements, e.g. Wall panels, as part of an entire vessel wall.
- wall plate is to be understood both as a single element as well as the entire wall of the vessel.
- the inventive introduction of optical fibers in the walls of the electric arc furnace, the temperatures or the expansion or vibration behavior of the metallurgical vessel can be represented on the hot side in different heights of the vessel.
- dynamic changes due to the process for example due to flow changes in the melt, are also detected.
- the concept allows a representation of the thermal and mechanical loading of the wall of the vessel in any operating condition, even in time dependence.
- search specifically for (process) errors such as longitudinal cracks in the wall or caking of melt on the hot side, as a cause for characteristic signatures on the subsequent cast product.
- the optical waveguides are not, as previously known, from the cold water-flowed cold side, but introduced directly from the thermally stressed hot side in the wall of the vessel.
- the heating power of the electrode can be reduced. Due to the accurate measurement, the arc furnace can be operated closer to the operating limit with more heating power, since no unnecessarily high safety reserve to protect the staves is necessary.
- a continuous groove is milled on the hot side, which is later closed on the hot side by a filler piece of the base material of the hot side.
- This filler is preferably fused by the friction stir welding again with the body.
- the groove depth is dimensioned such that the thermal stress caused by the welding process can not damage the optical waveguide.
- this concept has the advantage that the measuring fiber is arranged very close to the region in which the casting process takes place.
- optical fibers can be used for temperature measurement or strain measurement without requiring too long rise or fall times in cycles.
- rise times of only 0.1 s are achieved when using a sufficiently thin cladding tube which surrounds the optical waveguide. This means that when introducing an optical waveguide surrounded by a cladding tube in the groove of a hot side / copper plate still an increase in dead time or an additional rise time of another 0.25 s can be accepted without obtaining a result worse than in a known radiometric method.
- the optical waveguides are according to the invention, for example, in the range of 3 - 12 mm behind the hot side.
- grooves are produced, for example by means of a disc milling cutter, which have a width of one to two millimeters.
- the enveloped with cladding optical fiber h can be inserted.
- the grooves are preferably filled by matched to the width of the grooves metal strips as patches.
- the metal strips are connected at their side edges with the material of the copper plates. This can be done by a variety of technologies, such as welding or soldering. Further advantageous developments of the invention will become apparent from the dependent claims, the description and the drawings.
- the patches, which close the grooves made of the same material as the wall panels.
- the grooves have a cross section tapering towards the groove base. This prevents that during friction stir welding, a bolt driving with pressure over the weld metal can depress the filler piece too deeply and thereby crush the optical waveguide jacket tube.
- the grooves advantageously have an at least substantially trapezoidal cross-section. Due to the trapezoidal cross-section, the depression of the filler and the crushing of the cladding tube can be prevented.
- the filler pieces preferably have a cross-section adapted to the grooves, in particular a likewise trapezoidal cross-section.
- the filler pieces have a slight undersize relative to the grooves, in particular in the region which adjoins the surface of the wall pieces. This makes it possible that the filler can be connected by mechanical action, in particular by rolling or welding, with the material of the wall panels without damaging the optical waveguide cladding at the bottom of the groove.
- connection between the filler pieces and the material of the wall panels surrounding them laterally is preferably carried out by a welding operation, preferably by friction welding, in particular by friction stir welding.
- the optical waveguides in cladding tubes are introduced.
- the filler pieces and the wall panels are coated on their externally accessible surfaces with a layer of nickel or chromium.
- the optical waveguides are introduced into bores which run parallel to the hot-side surface of the wall plates and which are produced for example by laser technology.
- the optical fibers have a diameter of about 0.15 mm.
- the matching sheaths have a diameter of about 0.5 to 1 mm.
- the patches have a width of 1 to 2 mm.
- the optical fibers can be used metrologically in many ways. Depending on their purpose they are loosely in the grooves or holes, especially for temperature measurement, because for the temperature measurement, it is important that the optical fibers can contract or expand unhindered themselves due to a change in temperature.
- the optical waveguides are preferably laid in the vicinity of the copper staves. This has the advantage that the heating power of the electric de (n) of the furnace can already be reduced again as soon as the optical waveguides allow a failure of the staves in the near future.
- the optical waveguides are at least selectively, but preferably firmly connected over its entire length with the surrounding material of the wall and / or with the filler pieces. This form of attachment is required so that expansion of the vessel can be transmitted directly to the optical fiber and the optical fiber can emit signals representing the strains of the metallurgical vessel. Also, the temporal course of strains, vibrations and / or temperatures, as they are each detected with the optical waveguides, can be recorded and evaluated. It is understood that in the same metallurgical vessel according to their different uses both loosely laid and glued optical waveguides can be present in the grooves or holes on the hot side of the wall panels.
- the invention also relates to the use of optical waveguides in walls of metallurgical vessels.
- the optical waveguides measure the temperature of the wall, the molten metal of the first metal in the vessel or mechanical strains or vibrations of the wall.
- the data are used, for example, to control the casting level.
- the invention also relates to a method for producing a wall plate comprising a wall of a metallurgical vessel.
- a method for producing a wall plate comprising a wall of a metallurgical vessel.

H . in the representation on the upper side, grooves 2, 3 and 4, which have a rectangular, square or trapezoidal cross section and whose base is preferably rounded.
- grooves 2, 3 and 4 which have a rectangular, square or trapezoidal cross section and whose base is preferably rounded.
- optical fibers 5, 6 and 7 are inserted into it. From the top side / the hot side, the optical waveguides 5, 6 and 7 in the grooves are covered in each case with filling pieces 8, 9 and 10, respectively.
- the optical waveguides 5 to 7 consist of an optically conductive material having a refractive index which decreases in cross-section from the inside to the outside; they are preferably each received by metallic sheaths or sleeves and can endure temperature measurement temperatures up to 600 ° C as a continuous load.
- the wall plate 1 On its back, the wall plate 1 is flowed through by cooling water. The cooling water flows through channels (not shown).
- the optical waveguides 5 to 7 have at the end lens plug to decouple the light waves and supply them to an evaluation unit. As a result of the fact that the light waves are conducted via lens plugs from the housing of the component in the respective measuring position to the evaluation unit, a robust signal transmission is achieved.
- the optical waveguides 5 to 7 have a diameter of, for example, 0.15 mm without the cladding tube and including the Cladding tube, for example, 1 mm.
- the filler pieces 8, 9, 1 0, as shown in FIG. 2 illustrated by the filler 8, a preferably trapezoidal cross-section 20.
- side walls 21, 22 with an upper edge 23 of the filler piece 8 preferably form the same obtuse angle ⁇ , which is also present between the side walls 23, 24 of the groove 2 and the regions 1 6, 1 7 adjoining them laterally.
- the filler 8 may also have a slight undersize relative to the groove 2. It is then mechanically inserted into the groove 2h and, for example, welded or brazed to the regions 1 6, 1 7 surrounding the groove 2.
- a filling piece 27 (FIG. 3) is adapted sufficiently precisely to the shape of a groove 28 in a workpiece 29, for example a copper plate for a casting mold, which it is intended to cover from the hot side, the filling piece 27, after it has become has been put into the groove 28, preferably by friction stir welding with lateral portions 30, 31 connected.
- a Rlicksch spancing 32 is guided above the wall plate 1 in the direction of an arrow A over the course of the groove 28 on the filler 27, wherein a mounted on a tool shoulder 33 welding pin 34 in contact with the filler 27 simultaneously performs rotational movements.
- This heat up Filler 27 and the areas 30, 31 so strong that they enter into a material connection with each other due to the frictional heat, which has a high stability.
- optical waveguides in the region of cooling elements e.g. so- nant Kupferstaves
- introduction of the optical waveguides in the region of cooling elements, e.g. so- nant Kupferstaves, in the hot side of the metallurgical vessel advantageously allows a very fast and efficient way of fiber introduction.
- the time profile of the temperature of the wall of the vessel or of the molten metal in the vessel and / or the time profile of the expansion of the vessel can be detected with the aid of the optical waveguide and used, for example, to optimize / increase the electrode power.
- the electrode power is controlled in accordance with the considered temporal courses so that the walls of the vessel are not damaged.
