Abstract

PURPOSE:To provide a furnace wall and a furnace partition wall having excellent thermal deformation resistance, work executing ability, and heat cutoff properties by a method wherein long support rods are inserted in the direction of lamination through a heat insulating block formed such that rectangular ceramic fiber blankets are laminated together, and located vertically in juxtaposition. CONSTITUTION:In a furnace wall structure, support rods 5 are inserted through a heat insulating block 4 where ceramic fibers are compressed for lamination. A longitudinal bone 2 suspended from a suspension metal 1 and a lateral bone 3 forming a lattice in corporation with the longitudinal bone 2 are intercoupled by means of a bolt 8, and a support rod 5 of the heat insulating block 4 is locked to a support metal 6 located to the longitudinal bone 2 to locate the heat insulating block 4 in an engaged state in the lattice. A furnace partition wall is formed such that the heat insulating block is locked to the bracket of the longitudinal bone. As a result, the thickness of the wall can be increased to approximately 300mm and since the heat insulating blocks can be closely arranged in the lattice frame, cutoff properties for heat can be increased, no deformation, e.g. a warp, is produced, a work for building and repair of a furnace wall, e.g. mounting and removal of the heat insulating blocks, is facilitated.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a method for forming furnace walls such as heating furnaces and heat treatment furnaces in the metal industry and firing furnaces in the ceramics industry, and a furnace partition wall constructed by this forming method.

[Prior Art] In recent years, furnace walls and partition walls in heating furnaces and heat treatment furnaces in the metal industry, firing furnaces in the ceramics industry, and the like have increasingly been constructed using ceramic fibers.

FIG. 6 shows an explanatory diagram of the entire heating furnace as an example.

FIG. 6(a) is a side sectional view of the heating furnace 21, and FIG. 6(b) is a view taken along the line DD in FIG. 6(a). Entrance door 2 of this furnace

No. 2-64758 and Japanese Utility Model Application No. 63-150295 are disclosed.

FIG. 5 shows a sectional view of the conventional furnace wall 10 as an example. This furnace partition wall 10 has a partition wall main body made up of ceramic fiber blocks 11, each block 11 is supported and penetrated by a rad 12, and the lower surface of each block 11 is supported by an intermediate stop plate 13 attached to a support rod 12. is configured to do so.

Utility Model No. 61-164253, Utility Model No. 62-64758
In the techniques disclosed in Japanese Utility Model Application No. 63-150295, the support rods 12 of each ceramic fiber block have a rigid structure, and cannot withstand deformation of the support rods 12 over a wide temperature range. This is a decisive disadvantage in the case of movable walls such as furnace partitions. Further, since the support rod 12 is configured to extend through each block 11 in the vertical direction, there is a problem that the work of attaching and removing each block is complicated and the workability is poor.

The technique disclosed in Japanese Utility Model Publication No. 61-13543 has problems such as easy gas circulation (poor heat insulation and difficulty in making walls thick) because it is an aggregate of connected small blocks. there were.

[Problems to be Solved by the Invention] In other words, the prior art had problems in heat deformation resistance, workability, and heat insulation properties.

The object of the present invention is to provide a furnace wall forming method and a furnace partition wall that solve all of the above-mentioned opening movements.

[Means for Solving the Problems] The method of the present invention solves the above-mentioned problems, and consists of stacking rectangular ceramic fiber blankets whose sides are the wall thickness dimension and the other sides are the vertically adjacent dimensions to form a rectangular parallelepiped. A support rod that is longer than the lamination thickness is inserted into this insulation block in the stacking direction, and both ends of this support rod are locked to a support to connect the insulation blocks vertically, and the furnace wall is This is a furnace wall forming method characterized by forming a furnace wall.

The furnace partition wall of the present invention is formed by applying the above-mentioned method, and includes a lattice-like frame consisting of a large number of heat-insulating coated vertical ribs equipped with receiving brackets and horizontal ribs connecting the vertical ribs. , laminated rectangular ceramic fiber blankets,
The furnace partition wall is characterized by comprising a heat insulating block constructed by inserting a support rod in the stacking direction, both ends of which are locked to the receiving bracket.

[Operation 1] The method of the present invention is easy to construct, as it is possible to form a vertically connected furnace wall simply by locking a rectangular parallelepiped-shaped heat insulating block formed by laminating ceramic fiber blankets to a support. A dense wall can be obtained.

In the furnace partition wall of the present invention, the vertical and horizontal bones were assembled in a lattice shape as described above, and the intersections were freely joined with bolts. Additionally, a support is provided on the vertical frame to allow the support rod of the insulation block to be attached or removed. Therefore, the sides of each lattice can expand and contract to absorb temperature differences without causing thermal deformation.
Construction of the insulation block becomes extremely easy.

[Example] The furnace wall structure of the present invention and its details are shown in FIGS. 1 to 4. Figure 1 (a) is a front view of the furnace wall, Figure 1 (b) is the first
It is a side view of figure (a).

FIG. 2(a) shows an enlarged view of part A of the first space (a), and FIG. 2(b) is a sectional view taken along line BB in FIG. 2(a). FIG. 3 is a perspective view of the heat insulating block, and FIG. 4 is a detailed view of the bracket that receives the end of the support rod passing through the heat insulating block.

In the present invention, as shown in FIG. 3, a support rod 5 is inserted into a heat insulating block 4 made of compressed and laminated ceramic fibers, and a vertical frame 2 is suspended from a hanging hardware 1 as shown in FIG. The vertical ribs 2 and the horizontal ribs 3 forming a lattice are connected by ports 8, and the support rods 5 of the heat insulating block 4 are attached to the supporting hardware 6 provided on the vertical ribs 2, as shown in FIGS. 2 and 4. The heat insulating block 4 is locked and fitted into the grid.

In such a furnace partition wall, a solid furnace partition wall can be constructed labor-savingly by locking the heat insulating block to the brackets of the vertical frame.

It should be noted that the horizontal ribs 3 do not need to be insulated when buried between the insulation blocks 4, but if necessary, they can be provided with a heat insulating structure, as the vertical ribs 2 in FIG. You can also.

In addition, if the temperature difference between the partition doors is large and warpage in the vertical direction due to the temperature difference becomes a problem, the vertical warpage of the door can be reduced by dividing the vertical beams and freely connecting them.

[Effect of the invention 1 Since the present invention has the above-described structure, ■ The wall thickness can be increased to about 300 mm, and the insulation blocks can be installed within the lattice frame without any gaps, so the heat insulation is great. .

■ No heat-resistant deformation such as warping.

■ Easier construction and repair of furnace walls, including installation and removal of insulation blocks.
