Definitions

  • DE 28 53 160 C2 discloses a device for applying heat-resistant material to the inner surface of a furnace with an elongated spray tube, at the front end of which is arranged an angled spray nozzle which can be inserted into the interior of the furnace and aligned there by shifting and rotating.
  • a television camera of a surveillance system is located on the spray tube near the spray nozzle and is movable therewith only to be able to observe the eroded or worn portion of the inner surface of the furnace during application.

  • the object of the present invention is to propose a method of the type mentioned at the outset which can be carried out quickly and reliably with little technical effort.
  • this object is achieved in a method of the type mentioned at the outset by the following method steps:
  • a manipulator serving to renovate the lining e.g. B. a spray manipulator

  • the measuring unit only needs to be moved over the metallurgical vessel. In any case, you get optimal measurement results and thus a safe melting operation by simply checking the refractory lining.
  • a safe extension of the service life of the refractory lining can also be achieved by targeted refurbishment.
  • An additional manipulator for the measuring unit is unnecessary, which also saves space.
  • Another advantage of the invention is that the measuring unit can be retrofitted to an existing manipulator.
  • the data of the measured actual profiles can also be used to determine the volume of the refractory lining that has been worn away by wear at selected points (e.g. pre-wear areas).
  • the result can be used to optimize the use of the materials required for renovation (e.g. a spray compound).
  • a measuring unit with non-contact e.g. B. stereoscopic recording technology, which uses at least one stereo matrix camera pair, the two cameras may be variable in their distance from each other.

Abstract

L'invention concerne un procédé de mesure de l'épaisseur résiduelle du garnissage réfractaire recouvrant la zone de paroi et/ou de base d'un récipient métallurgique, par ex. d'un four à arc, au moyen d'une unité de mesure pouvant être placée en position de mesure. Ce procédé comprend les étapes consistant à : monter l'unité de mesure sur un manipulateur servant à rénover le garnissage ; déplacer l'unité de mesure pour la mettre en position de mesure, sur ou dans le récipient métallurgique, au moyen du manipulateur ; mesurer l'épaisseur résiduelle du garnissage recouvrant la zone de paroi et/ou de base ; évaluer les données de mesure et éventuellement utiliser ces données de mesure lors de la rénovation subséquente des zones d'usure déterminées. L'invention se rapporte en outre à un dispositif permettant d'exécuter un tel procédé.
