Definitions

  • the present invention relates, in particular, to blast furnace cowpers, that is to say reversing devices in which the air sent to the blast furnace nozzles is heated.
  • Such an apparatus comprises a side wall consisting of welded sheet plates, surmounted by a dome also made of welded sheet.
  • the enclosure formed by the side wall and the dome houses a combustion chamber and a ruching chamber.
  • the purpose of the present invention is to provide a lining of the double jacket more specially adapted to the thermal stresses to be transmitted, while being easy to implement.
  • the subject of the invention is an envelope for a cowper or similar air heating device comprising a first wall made of welded sheet metal and comprising a second wall of welded sheet metal, external and parallel to the first, these two walls delimiting a space filled with a filling material, characterized in that the filling material is based on shot of a metal or a light alloy, embedded in a binder based on thermosetting resin.
  • the invention also relates to a method of manufacturing such an envelope: in which an inner sheet metal wall is doubled by a second outer sheet metal wall, parallel to the first, this second wall delimiting with the first wall a space, characterized in that this space is filled with a filling material comprising shot of a metal or a light alloy and a binder based on thermosetting resin.
  • a part of a cowper envelope or similar device comprising a metallic inner wall 1 made of welded sheet, the thickness of which may be comprised, for example between 15 and 30 mm.
  • a refractory lining 2 On the face of this wall facing the interior of the device is a refractory lining 2.
  • the outer wall is preferably made in the same grade of steel as the inner wall and has a roughly comparable thickness.
  • the inner wall comprises for example a lower part 1a having a thickness of 24 mm and an upper part 1 having a thickness of 17mm.
  • the thickness of the outer wall 4a, 4b may vary accordingly, as shown in the drawing.
  • the thickness of the interval 5a, 5b of limit between the two walls can vary between for example 3 and 30 mm, a thickness of the order of 10 mm being however preferred.
  • the filling material of the gap between the walls is, according to the invention, constituted by aluminum shot or an aluminum alloy whose particles preferably have the dimensions between 0.2 and 2 mm, for example, a dimension of the order of 0.5 or 1.5 mm being particularly favorable.
  • the average size of the metal granules is chosen so as to obtain optimal filling of the cells and is, in any event, less than the minimum width of the gap between the two walls.
  • aluminum will be used or preferably an aluminum-based alloy or another metal or light alloy with high thermal conductivity.
  • the interstices between the metal granules are filled with a binder based on resin or a mixture of thermosetting resin resistant to a temperature equal to or greater than 110 ° C.
  • This resin can for example be a powdered phenolic polyurethane resin or in the form of a liquid gel, containing the adjuvants necessary for its hardening and possibly a filler as is conventional in the techniques of molding or casting of such resins.
  • the filling of the cells can be carried out as follows: first of all, in a mixer, the metal particles are coated, using the resin in powder or in the form of liquid gel.
  • the mixture thus prepared is put into place, by injection or by pouring, optionally under neutral gas such as nitrogen, through orifices 7 into which tubes such as 8 are introduced, for example by screwing. vent holes are provided, if necessary in this same wall 4.
  • This positioning of the mixture can be carried out cold.
  • a vibration operation is carried out so as to obtain an excellent filling of the cells. This can be done using a high frequency unidirectional vibrator.
  • the curing of the resin takes place between 20 minutes and one hour approximately after the introduction of the mixture, this duration naturally depending on the proportions of hardener contained in the mixture.
  • This hardening can possibly be accelerated by a slight increase in temperature.
  • the orifices such as 7 are then closed, for example by means of screwed or welded plugs, so as to restore the continuity of the outer wall 4.
  • the spacers 3 can be omitted, the method however being implemented under the same conditions.
