Definitions

  • the present invention relates to furnace walls, more particularly to a process for producing a roof wall and the right foot of an industrial oven.
  • Industrial ovens in which ceramics, earthenware (bricks or other) are fired, etc. consist of a gas-tight metal wall from the outside towards the inside, then of a series of refractory materials arranged in successive layers.
  • the stack of insulating materials is held against the metal wall by anchors which are on the one hand welded to the internal ribs of the sheet and on the other hand anchored in the refractory lining, as shown in FIG. 1.
  • the materials are the same dimensions as the plate on which they are previously stacked.
  • the object of the invention is to overcome this drawback and an object is an industrial oven wall of the type comprising an external metal shield, characterized in that it comprises a layer of elastic insulating material compressed in the direction perpendicular to the shield.
  • the slab is presented obliquely and rests on the shoulders of the hooves closest to the previous row.
  • the layer of compressed fibers is introduced on the inclined surface; remove the straps and straighten the slab.
  • the wall according to FIG. 1 represents a known vault: it comprises an outer metal sheet 100, this sheet having a succession of grooves 101 and ribs 102.
  • the anchors 105 are arranged, on the inner side, at the top of the ribs, and are there welded.
  • the refractory materials are arranged in successive layers and held by the anchors. The compaction of the materials and the progressive collapse of the layers allows the passage of gases and their accumulation at the bottom of the grooves.
  • the water in vapor condenses and runs on the edge of the ribs. This condensate is very corrosive and attacks the welds and the shell.
  • the number of layers of panels is provided so as to leave a substantial space 14 between the last layer and the lower pavement, into which the compressed stretch layer is introduced.
  • the dimension of this space 14 and the initial compression of the layer of fibers 11 are chosen so that the layer 11 can be easily introduced and, after expansion, it is still compressed. Thus all of the layers between the paving and the metal wall are permanently in compression.
  • the space 14 is approximately 220 millimeters and the layer 11 of compressed fibers consists of superimposed strips; before compression the thickness is of the order of 275 millimeters.
  • This layer is compressed, the thickness being reduced to 200 millimeters, and thus maintained by straps. It is introduced, placed on the paving and the straps are removed. The layer relaxes and fills the space of 220 millimeters.
  • the compressed layer can be produced in various ways without departing from the scope of the invention; the sheet can in particular be compressed without being cut into superimposed strips, but wound or folded over itself several times, etc.
  • the flattening of the paving and the compressed layers is carried out, in the embodiment, as follows: first of all the rods 6 (without shoe 9) and the first inextensible layers 12, 13 are flat . The tiles are then installed one by one with the layers compressed, and held by the shoes.
  • the tiles have on at least two opposite edges connecting means allowing each of them to rest and / or restrain on its neighbor.
  • These connecting means are for example made by concordant shape, of the tenon-mortise type, recess-projection in general, tile profile, free hinge, etc.
  • the wall is in compression throughout its thickness, which avoids the formation of pockets and passages allowing gas leaks.
  • This oven wall can be made both for the vaults, which are substantially horizontal, and for the vertical walls.
