Description
i 1 2477690 La présente invention concerne des. modules en matériaThe present invention relates to the present invention. modules in materia
fibreux, utilisés pour le garnissage des parois de fours électrique employant, comme émetteur calorifique, des résistances en fil fibrous materials used for lining electric furnace walls employing, as a heat emitter, wire resistors
boudiné ou en ruban à petites spires. pudding or ribbon with small turns.
Les modules commercialisés sont de forme parallèlépi- pédique à base carrée et à hauteur variable en fonction de la tempé The modules marketed are square parallelepipedic in shape and variable in height depending on the temperature.
rature de la face chaude.erasure of the hot face.
Leur assemblage consiste dans un empilage de petites sections de couches fibreuses(ou d'une nappe à plis multiples), les Their assembly consists of a stack of small sections of fibrous layers (or of a sheet with multiple folds), the
quelles sont pressées, puis sanglées pour le maintien en pression. which are pressed and then strapped to maintain pressure.
L'emploi de nappes en matériaux fibreux pour le garni sage des parois de fours électriques se heurte à la difficulté de l'implantation des résistances émettrices sur les faces vertical Actuellement, on résout cette difficulté soit par l'inclusion, par moulage sous vide, des résistances dans la face chaude des blocs fibreux, soit par l'interposition de murets supports en matériaux réfractaires céramisés porteurs de tubes de The use of plies made of fibrous materials for filling the walls of electric furnaces faces the difficulty of implanting the emitting resistors on the vertical faces. Currently, this difficulty is solved either by inclusion, by vacuum molding, resistances in the hot face of the fibrous blocks, either by the interposition of walls of ceramized refractory materials carrying tubes of
même qualité sur lesquels est placé le fil résistant. same quality on which is placed the resistant wire.
La première solution limite la dimension des fours la seconde complique le garnissage et en augmente l'inertie thermiqI The first solution limits the size of the furnaces the second complicates the packing and increases the thermal inertia
et les déperditions calorifiques.and heat losses.
L'invention remédie à ces inconvénients, en permettant de n'utiliser que des matériaux fibreux, ce qui augmente le rendement thermique des fours et simplifie la mise en place du-garni sage, par un module de garnissage de four constitué de couches en matière fibreuse, superposées en une pile comprimée suivant une direction de compression, caractérisé en ce que, parmi ces couches, il en est au moins une qui dépasse de la pile suivant une direction The invention overcomes these drawbacks, by allowing the use of only fibrous materials, which increases the thermal efficiency of the furnaces and simplifies the installation of the garni-wise, by a furnace packing module consisting of layers of material fibrous, superimposed in a stack compressed in a direction of compression, characterized in that, among these layers, there is at least one which protrudes from the stack in one direction
sensiblement perpendiculaire à celle de compression par un prolonge- substantially perpendicular to that of compression by an extension
ment non comprimé.uncompressed.
Ainsi se trouve réalisées entre les prolongements et la couche adjacente supérieure des corniches enpente, inclinées des prolongements vers la pile, surlesquellesles résistances métalli Thus is realized between the extensions and the upper adjacent layer of the cornices slope, inclined extensions to the pile, on which the metal resistances
ques- trouvent logement et support.they find housing and support.
Suivant une variante préférée, on intercale dans la pile de couches une nappe de plus grande dimension pliée par moitié avec dépose à l'intérieur du pli d'une bande de fibre de même According to a preferred variant, a ply of larger dimension is folded in the stack of layers, folded in half, with removal of a strip of fiber of the same inside the fold.
qualité ou d'un tube céramique.quality or ceramic tube.
Lors du presAage de l'ensemble des couches multiples, s'effectuant seulement par la surface de.- couches de moindre dimension, il se forme un boudin sur la partie libre de compression des nappes en surlongueur. Ce boudin, en saillie de la face chaude, During the presage of the set of multiple layers, taking place only by the surface of smaller layers, a flange is formed on the free compression part of the over-long plies. This boudin, protruding from the hot face,
forme un gouttière dans laquelle peuvent être déposées les résis- form a gutter in which the
tances boudinées,qui sont ainsi d'autant mieux maintenues que le tube céramique impose au boudin une forme arrondie et s'oppose à son affaisement. They are thus all the better maintained because the ceramic tube imposes on the boudin a rounded form and opposes its slackening.

La figure 3 est une vue en perspective de deux modules jointifs constituant une partie d'un garnissage de four à résistance électrique, et La figure 4 est une vue en perspective d'une tige FIG. 3 is a perspective view of two contiguous modules constituting a part of an electric resistance furnace lining, and FIG. 4 is a perspective view of a rod.
demaintien en place d'un enroulement résistant. tomorrowtien in place of a resistant winding.
Le long de la paroi P verticale d'un four, on plie en accordéon une longue nappe 1 en fibres d'alumine, de manière ce que les faces des couches 2 formées soient adjacentes entre elles et à ce que les troisième, neuvième et quinzième plis incluent un tube 3 en fibres d'alumine ou en un autre matériau, éventuellement peu compressible et dépassent horizontalement de la pile en des prolongements formant trois boudins 4 raccordant les Along the vertical wall P of an oven, a long ply 1 made of alumina fibers is folded in accordion so that the faces of the layers 2 formed are adjacent to each other and the third, ninth and fifteenth folds include a tube 3 of alumina fiber or other material, possibly slightly compressible and protrude horizontally from the stack in extensions forming three strands 4 connecting the
deux couches dont ils sont issus.two layers from which they come.
A la figure 2 la pile, au lieu d'être constituée par une nappe en accordéon, est constituée par une succession de couches In FIG. 2 the stack, instead of being constituted by an accordion sheet, is constituted by a succession of layers

gements de certaines couches adjacentes forment des boudins 4. some adjacent layers form bundles 4.
On place les piles dans une forme et on les comprime suivant la verticale. Puis à l'aide de sangles 5 (figure 3), on maintient la compression. Comme celle-ci ne s'exerce pas sur les boudins 4, chacun de ceux-ci reste décomprimé et crée entre lui et The cells are placed in a shape and compressed in a vertical fashion. Then with the aid of straps 5 (Figure 3), the compression is maintained. As this one is not exerted on the rolls 4, each one of them remains decompressed and creates between him and
la couche supérieure adjacente à celle 'qui est munie du prolonge- the upper layer adjacent to that which is equipped with the
ment un logement pour une résistance 6 éléctrique. a housing for electrical resistance.
La figure 4 représente un élément pour parfaire le maintien des résistances 6 électriques hélicoïdaleslorsque les modules garnissent des parois soumises à des vibrations. Cet élément se compose d'une tige 7 terminée d'une part par un crochet 8 en forme d'hameçon et d'autre part par un enroulement 9 en spirale permettant de monter la tige 7 à rotation sur un enroulement 6 de résistance électrique. La tige7 etl'enroulement6 sont en fil métallique FIG. 4 shows an element for perfecting the maintenance of the helical electric resistors when the modules cover walls subjected to vibrations. This element consists of a rod 7 terminated on the one hand by a hook-shaped hook 8 and on the other hand by a spiral winding 9 for mounting the rod 7 to rotate on a winding 6 of electrical resistance. The rod7 and the winding6 are made of wire
de même nature et de même section. of the same nature and of the same section.
Pour maintenir l'enroulement 6 contre la face verticale du module de garnissage, on monte la tige 7 à rotation sur l'enroulement 6 par l'intermédiaire de l'enroulement 9, on place l'enroulement 6 entre le boudin 4 et une couche se trouvant au-dessus de celle qui dépasse, on fait tourner la tige 7 dans un sens jusqu'à ce que le crochet 8 se pique dans une couche et on continue à faire tourner la tige 7 dans le même sens de manière à ancrer le crochet dans les couches suivant la direction de compression. To maintain the winding 6 against the vertical face of the packing module, the rod 7 is mounted to rotate on the winding 6 by means of the winding 9, the winding 6 is placed between the bead 4 and a layer located above the one that protrudes, the rod 7 is rotated in one direction until the hook 8 is pricked in a layer and the rod 7 is continued to rotate in the same direction so as to anchor the hook in layers in the direction of compression.
