Definitions

  • the invention relates to a method in particular for determining the state of the tapping of a metallurgical vessel according to the preamble of claim 1.
  • WO 2007/107242 is a method for determining the wall thickness or wear of the lining of a metallurgical melting vessel with a non-contact scanning system Detection of the lining surface with determination of the position and orientation of the scanner system and assignment to the position of the melting vessel revealed by the detection of spatially fixed reference points.
  • a perpendicular reference system is used and the inclinations of two axes with respect to a horizontal plane are measured by inclination sensors.
  • the measurement data of the scanner can be transformed into a perpendicular coordinate system and thus an automated measurement of the respective actual state of the lining of the melting vessel is possible.
  • the present invention has the object to provide a method according to the type mentioned, by means of which the durability of the refractory lining of the tapping of a metallurgical vessel and the process itself can be optimized and reduces manual decisions for it or virtually eliminated.
  • the method according to the invention provides that data of a respective vessel are collected and stored in a data structure, and from all the measured and determined data or parameters, in particular the refractory lining of the tap, a computer model is created by means of which these data or parameters Calculations and subsequent analyzes are evaluated.
  • the method relates in particular to metallurgical vessels, such as such a vessel 10 as an embodiment in Fig. 1 is shown cut.
  • the vessel is a known converter 10 for steelmaking.
  • This converter 10 consists essentially of a metal housing 15, a refractory lining 12, a tapping 20 and gas purging 17, 18, which can be coupled with a gas supply not shown in detail.
  • molten metal is metallurgically treated, for example by a blowing process, which is not explained in detail.
  • a plurality of such converters 10 are in use in a steel mill for steel production at the same time and it is to capture the data for each of these converters.
  • This tapping 20 is composed of a tapping channel 21, the latter forming sleeve-shaped tapping blocks 22 and a metal outlet pipe 24 together.
  • this tap can also be configured differently than shown.
  • the method can in principle be applied to various metallurgical vessels, such as electric furnace, blast furnace, steel ladle, non-ferrous metal vessel such as aluminum smelting furnace, copper anode furnace or the like.
  • the method is characterized by the fact that it can be applied for different different vessels.
  • the refractory linings of the taps of all standing in operation converter and possibly pans are determined in which the same melt is first treated in a converter and subsequently poured into steel pans.
  • the data divided into groups of a respective tap 20 of the converter 10 are comprehensively collected and stored in a data structure.
  • a recording takes place during the period of use of the respective converter 10, such as melt quantity, temperature, composition of the melt or slag and their thickness, tapping times, temperature profile, treatment time and / or metallurgical parameters; like special additives in the melt.
  • melt quantity such as melt quantity, temperature, composition of the melt or slag and their thickness, tapping times, temperature profile, treatment time and / or metallurgical parameters; like special additives in the melt.
  • tapping times temperature profile, treatment time and / or metallurgical parameters; like special additives in the melt.
  • the invention is characterized in particular by focusing primarily on the tapping time for the recurrent calculations or analyzes by the computer model. With the measurements of the tapping times very reliable conclusions about the wear and other factors, such as changes with increasing service life of the refractory tapping stones, can be drawn.
  • a measurement of the inner diameter of the refractory lining in the tapping 20 advantageously sections. It is sufficient if the measurement of the wall thicknesses of the lining 12 is carried out after a number of taps. It can then be determined other process parameters, such as filling or Abstichart the molten metal in or out of the melting vessel.
  • a mathematical model is created from at least part of the measured and determined data or parameters, by means of which these data or parameters are evaluated by calculations and subsequent analyzes.
  • the maximum duration of use, the wall thicknesses, the materials and / or the care data of the refractory lining of the tapping 20 or, conversely, the process sequences in the treatment of the melt can be optimized. It can be from these analyzes sometimes on the further use without or with repairs of the refractory lining of the tapping 20. It requires no more or only a limited experience manual interpretation of the duration of use of the refractory lining of the tapping 20 and the other sizes to be determined, such as wall thickness, choice of material etc ..
  • the tapping 20 is expediently subdivided into several sections, for example into an inlet in the container interior, into a plurality of sections in the tapping channel 21 and into an outlet at the outlet connection 24.
  • the data is checked for plausibility after the acquisition, and if one or more values are missing or torn out, these are respectively corrected or deleted. After preferably individually checking the data, these are saved to a merged valid record.
  • a reduced number is selected from the measured or determined data or parameters for the recurrent calculations or analyzes, this taking place as a function of empirical values or by calculation methods.
  • This selection of the measured or determined data or parameters for the recurrent calculations or analyzes takes place by means of algorithms, for example a random feature selection.
  • the data is used for statistical purposes or for later recording for the reconstruction of production errors or the like.
  • the calculation model is adapted as a further advantage of the invention, by which the wear can be calculated or simulated taking into account the collected and structured data.
  • This adapted calculation model is especially suitable for use of test purposes in order to test or simulate process sequences and to carry out targeted changes.
