Definitions

  • the invention relates to a heat-insulating lining of industrial furnaces with refractory blocks (for example refractory bricks) and steel anchors, which hold the blocks on a metal wall, and a casting with a low-viscosity refractory mass, which causes a flat, circumferential positive locking anchoring of the blocks.
  • refractory blocks for example refractory bricks
  • steel anchors which hold the blocks on a metal wall
  • a casting with a low-viscosity refractory mass which causes a flat, circumferential positive locking anchoring of the blocks.
  • the object underlying the present invention is to propose a heat-insulating lining of industrial furnaces, which is less time-consuming and less expensive than the known linings.
  • each block a circumferential groove is formed, that engages at least one steel anchor with a tip in the groove of a block and that the blocks are circumferentially positively anchored by means of hardened refractory material.
  • the blocks are shaped as blocks of porous refractory material (eg refractory bricks), the length of one side of a square being 200mm to 400mm, the thickness being 110mm to 230mm.
  • the circumferential groove is inserted in each block in the rear half of the narrow sides.
  • temperature-resistant fiber products eg ceramic fiber paper based on aluminosilicate high-temperature wool
  • the temperature-resistant fiber products are advantageously glued to two narrow sides, so that by the contiguity of the blocks creates a circumferential expansion joint for each block. So it does not have to be additional expansion joint can be installed, since the expansion of each block is compensated by the circumferential joint.
  • the front portion of a block between the groove and the outer surface is made slightly larger than the rear portion of the block between the groove and the back, facing the wall to be clad.
  • the steel anchors are advantageously formed of flat iron, the flat iron slotted and punched in the front and have a hole in the rear of the attachment of the steel anchors to the wall.
  • the front section of a steel anchor is bent upwards or downwards so that one tip points upwards and one downwards.
  • the down-facing tip is pushed into the groove of a raised block and holds this block against the wall.
  • each block is secured in this manner by a steel anchor.
  • the upward-pointing tip of a steel anchor causes the attachment of the upper block constructed thereon.
  • the blocks are assembled in combination and, unlike the prior art, are not grouted with mortar.
  • the steel anchors on a flat iron with a hole in the front and rear area.
  • the hole in the rear area is used to attach the steel anchors to the wall.
  • a round iron is inserted and slightly squeezed in the middle, so that it does not fall through the hole of the flat iron.
  • This arranged on the steel support member round steel is approximately perpendicular to the plane of the flat iron, with a tip of the round steel facing up and a tip of the round steel down. If such a steel anchor held by its rear hole on the wall, the downward-pointing tip of the round steel is pressed into the groove of a block erected and keeps this block on the wall. The pointing up the top of the round steel causes the attachment of the built-up upper block.
  • each block is held at its upper and lower sides by two steel anchors each, the tips of which penetrate into the corresponding groove of the block. This causes each block to be anchored at four points.
  • this wall is back-poured with a low-viscosity refractory material, such as concrete.
  • This mass passes behind the blocks, into the gap between the blocks and into the groove of each block and hardens there. Then each block is anchored all around. It is not necessary to install a console. Due to the faster installation, the desired cost savings are given.
  • the refractory mass creates a circumferential positive anchoring of each block.
  • porous refractory blocks 1 are used, the view of the back or perspective view in Fig. 1 respectively.
  • Fig. 2 is shown.
  • the block 1 is cuboid shaped and has in the rear half of his Narrow the circumferential groove 2 on.
  • the temperature-resistant fiber products 4 are glued between the groove 2 and the outer surface.
  • the front portion 3 of the cuboid of the block 1 is designed slightly larger than the rear portion 5 of this block. 1
  • FIG. 3 To produce in the cutout heat-insulating lining, several blocks 1, the in Fig. 1 and Fig. 2 have shown shape, juxtaposed. Each block 1 is shaped the same. It is not necessary to additionally cut or process the blocks.
  • Fig. 4 is the cross section AA according to Fig. 3 Both figures will now be described in detail.
  • Each block 1 has the circumferential groove 2 and is covered with the temperature-resistant fiber products 4 on two narrow sides. Since each block 1 on two sides with the temperature-resistant fiber products 4 (according to Fig. 2 at the top and at the right side), after the blocks are assembled in a composite, a circumferential expansion joint for each block occurs by the juxtaposition of the fiber products 4.
  • the according to Fig. 2 to the left-facing front portion 3 of the block 1 forms according to Fig. 3 the outer surface, so that each block 1 according to Fig. 3 right and above with the temperature-resistant fiber products 4 described is provided.
  • Fig. 4 is the section AA according to Fig. 3 shown.
  • the wall of the industrial furnace has the metal wall 7 and the insulating plates 13.
  • the hooks 8 are fixed to the metal wall 7 in a conventional manner and penetrate the insulating plates 13.
  • At the outer end of the hook 8 is bent upward to receive the hole 11 of the steel anchor 6.
  • the steel anchor 6 is formed of a flat iron whose slotted and punched out front portion is bent in each case to a tip 9 upwards or to a top 10 downwards.
  • Fig. 5 shows the perspective view of such a steel anchor 6.
  • the tip 10 penetrates according Fig. 4 down into the groove 2 of a block 1 a.
  • the tip 9 engages in the groove 2 of the upper block 1.
  • Each steel anchor 6 holds in this way two blocks 1 on the wall 7.
  • In the rear region of the steel anchor 6 is a hole 11, in which the hook 8 engages.
  • Fig. 6 shows the perspective view of a steel anchor 14 can be used as an alternative to the steel anchor 6 just described.
  • the use of such a steel anchor 14 corresponds to the just described manipulations in the description of Fig. 3 and Fig. 4 .
  • the in Fig. 6 shown steel anchor 14 has in its rear region, the hole 15 and in its front region, the hole 16.
  • In this front hole 16 is the round steel 17 which was inserted into this hole 16 and is easily crushed during manufacture, so that it does not fall out of the hole. This results in the bead 20.
  • the down from the steel anchor 14 outstanding tip 19 of the round bar 17 engages when setting up the blocks 1 in the groove 2 of a block 1 a.
  • the upper tip 18 of the round bar 17 engages in the groove 2 of the upper block 1.
  • Each steel anchor 14 holds in this way two blocks 1 on the wall 7 analogous to the representation of the steel anchor 6 according to Fig. 3 and Fig. 4 ,
  • FIG. 3 Several blocks 1 are now set up in the network, as in Fig. 3 is shown. Each block 1 is held with two steel anchors 6 on its upper side and with two steel anchors 6 on its underside. Each steel anchor 6 engages in the groove 2 of each block 1 in the manner described and illustrated.
