Definitions

  • the invention relates to a method for restoring the refractory lining of a pan for liquid steel.
  • pans which consist of a Steel tanks with an inner refractory lining.
  • This refractory lining is subject to, especially in the upper Field of slag formation, a chemical and mechanical Wear, so the pan delivery from time to time Time needs to be renewed.
  • the refractory delivery Because the pans fall below a certain minimum thickness the refractory delivery for security reasons not may be used more, but still not one there is insignificant residual layer thickness of the feed the refractory delivery is built up in two layers, that a so-called Permanent food is arranged, which is the inside actual wear lining connects.
  • the permanent feed used according to the state of the art exists made of refractory plates, which are about 20 mm thick and to avoid stuck on top of each other offset by continuous joints become.
  • DE OS 29 14 686 describes a method and a device described for removing used refractory lining, at least one by means of a cutting device extending continuously along the entire vessel wall Slit made in the feed to be removed to the compressive stresses prevailing in the feed exploit to finally facilitate the removal of the feed.
  • a division into a permanent lining and a wear lining is not scheduled.
  • the feed must be power tools are broken open.
  • the invention is based on the object On the one hand to remove used refractory lining, on the other hand also the application of a new one Simplify wear chuck considerably.
  • the permanent lining is monolithic using a formwork template manufacture.
  • prefabricated refractory molded parts as they have been used so far become.
  • the previously required gluing of the individual refractory plates on the inner pan wall are required.
  • the permanent feed applied according to the invention is with the help of Anchor elements arranged on the inner pan wall are firmly connected to it, so that overall the dimensional stability the pan or the permanent feed is raised.
  • the layer thickness of the permanent lining is preferably between 60 and 150 mm, is therefore essential compared to the prior art elevated. For this reason, the rest is to be processed Layer of the wear lining relatively thin, so that the amount of residues to be disposed of is also comparatively is low.
  • the anchor elements already mentioned are preferably dovetail-shaped trained and are, for example with the well-known stud welding process on the inner pan wall welded. These anchor elements ensure excellent Attachment of the permanent feed and an increase in stability the pan. It is with the refractory lining according to the invention possible between the inner pan wall and to provide a fiber insulation material for the actual permanent feed, which is a significant improvement in the insulation effect has the consequence that the outside temperature of the pan of usual approx. 300 ° C to approx. 200 ° C.
  • the fiber insulation mats can in a known manner on the inner surface of the Socket wall between the anchor elements are glued, the anchor elements with the integrated bases of the cast Refractory a compression of the fiber mats prevent.
  • the refractory material used for the permanent feed can Contain steel needles, for example, in an amount of approx. 1% can be added. Through this internal reinforcement z. B. thermal stresses are more easily absorbed or reduced, so that the susceptibility to tearing of the feed decreases.
  • the wear lining to be applied to the permanent lining exists usually from a spinel-forming casting compound, see above that it is advantageous to the permanent feed before applying the Dry the lining so that the spinel-forming Masses not caused by additional water vapor from the permanent feed can be hydrated.
  • the casting compounds used for the permanent and wear lining are preferably set thixotropically, so that they with With the help of well-known pumping and distribution systems in the Gap between the pan wall and the formwork template can be introduced.
  • the drawing figure shows a vertical section through a Steel pan 1 with a refractory delivery 2.
  • the refractory delivery 2 consists of a wear lining 3, which the Melt is facing and a permanent feed 4 that is the inner pan wall 5 connects.
  • the permanent feed 4 is on the pan wall 5 with the help of dovetail anchors 6 attached.
  • the permanent lining 4 with the help of the dovetail anchor 6 or them surrounding base 12 supports against the pan wall 5.
