形成される。2. Description of the Related Art Inorganic fiber blocks are widely used as furnace wall materials (lining materials) for various industrial furnaces. In general, the inorganic fiber block is formed using, as materials, alumina silica fibers, mullite fibers, alumina fibers, and inorganic fibers obtained by mixing one or more of these fibers after heat treatment.

A through hole is formed in the metal substrate. A large-diameter mounting hole is provided in the center of the block to communicate with the through-hole of the metal substrate. On the other hand, a large number of studs are welded to the inner surface of the furnace shell to fix the blocks.

Fit the through hole in the metal fitting board of the block. Next, a nut is screwed into the stud to fix the block together with the metal substrate to the furnace shell. At this time, a nut is fastened by inserting a tool through a mounting hole provided in the center of the block. Finally, a small piece, a bulk, or the like of a blanket of the same material as the block is filled in the mounting hole to close the mounting hole.

ある。As described above, the mounting hole of the inorganic fiber block is a space previously reserved for inserting a tool. The mounting holes are formed by removing the material of the block with a drill or the like, or by embedding a paper tube. When this block is lined in a furnace, it is necessary to fix the inorganic fiber block to the stud of the furnace shell and then fill the mounting hole with a refractory heat insulating material to close the hole.
【０００６】従来、取付穴は、無機繊維のブランケット
やバルク等を単に押し込んで塞ぐのが一般的であった。Heretofore, it has been general that the mounting hole is simply closed by simply pushing in a blanket or bulk of inorganic fibers.

In addition, much work and time are required for blanket and bulk filling operations. Furthermore, heat insulation properties were not sufficient because uniform filling was difficult.

を目的としている。[0008] In view of the problems of the prior art, the present invention makes it possible to substantially improve the work efficiency during construction as compared with the conventional filler, without the danger of falling off due to the tight fit in the mounting hole. It is an object of the present invention to provide an inorganic fibrous filler and a furnace using the inorganic fibrous filler and having excellent heat insulating properties.

る。According to a first aspect of the present invention, there is provided an inorganic fibrous filler for filling a mounting hole of an inorganic fiber block, wherein a flammable holding member is arranged outside the inorganic fiber material,
The gist of the present invention is an inorganic fibrous filler characterized in that the inorganic fiber material is held at least in a state of being compressed in the radial direction.

機繊維材の半径方向の膨脹によって生じる充填材繊維と
ブロック繊維間の絡みや繋がりである。The inorganic fibrous filler of the first invention has some degree of entanglement or connection with the block fibers in the opening of the holding member. Furthermore, since the inorganic fiber material is kept in a radially compressed state by the flammable holding member, the holding member is burned out at the first operation, and the inorganic fiber material expands. Due to this expansion, the filler fiber and the block fiber adhere to each other, the entanglement and connection between the two become more reliable, and the filler is firmly fixed to the block. Particularly important here is the entanglement or connection between the filler fibers and the block fibers caused by the radial expansion of the inorganic fiber material.

填材は、取付穴の大きさに合せて適宜作製できるので、
充填作業を容易にかつ短時間で完了できる。As described above, since the filler fibers and the block fibers of the homogeneous filler are firmly entangled in the radial direction of the filler, a furnace having excellent heat insulating properties can be obtained. For the same reason, it is possible to reliably prevent the filler from falling off. Also, the filler can be made appropriately according to the size of the mounting hole,
The filling operation can be completed easily and in a short time.
【００１３】保持部材として燃性糸を用いた場合には、
燃性糸が無機繊維と比較して滑り易いので、取付穴への
挿入が容易となる。When a flammable yarn is used as the holding member,
Since the flammable yarn is more slippery than the inorganic fiber, it can be easily inserted into the mounting hole.

【実施例】以下、図面を参照して本発明の実施例を説明
する。Embodiments of the present invention will be described below with reference to the drawings.

方向に圧縮された状態になっている。FIG. 1 is a perspective view showing an inorganic fibrous filler 1 of the first invention. The inorganic fibrous filler 1 (hereinafter, referred to as a filler) is mainly composed of an inorganic fiber material (blanket) 2 and is formed in a columnar shape. The outside of the filler 1 is covered with the holding member 3, and the inorganic fiber material 2 is in a state of being compressed at least in the radial direction.
【００１７】圧縮率は、体積圧縮率で５％〜４０％程度
が望ましい。圧縮率をこの範囲に設定することによっ
て、充填材繊維とブロック繊維の間に繋がりを持たせる
ことが可能となる。The compression ratio is desirably about 5% to 40% by volume. By setting the compression ratio in this range, it is possible to provide a connection between the filler fiber and the block fiber.
【００１８】充填材１は、無機繊維ブロック（５）と同

維材２はアルミナシリカ繊維、ムライト繊維、アルミナ
繊維、及びこれらの繊維を熱処理したものを一種又は二
種以上混合して得た無機繊維を材料として形成される。The filler 1 is preferably made of an inorganic fiber material 2 of the same material as the inorganic fiber block (5). The inorganic fiber material 2 is made of alumina silica fiber, mullite fiber, alumina fiber, and heat treatment of these fibers. It is formed using inorganic fibers obtained by mixing one or two or more of these materials.
【００１９】無機繊維材２の形状は、円柱状が好ましい

の他の形状でも良い。なぜなら、無機繊維材は保持部材
３で圧縮状態に保持する際に、断面形状はある程度自由
に変形して円に近くできるからである。The shape of the inorganic fiber material 2 is preferably cylindrical, but may be a square pillar obtained by cutting an inorganic fiber blanket or other shapes. This is because, when the inorganic fiber material is held in a compressed state by the holding member 3, the cross-sectional shape can be freely deformed to some extent and become close to a circle.
【００２０】保持部材３としては、燃性糸３を用いるの
が望ましい。燃性糸３は、炉の稼働時に焼失する糸であ

きる。もちろん、これらの混紡糸であっても良い。As the holding member 3, it is desirable to use a flammable yarn 3. The flammable yarn 3 is a yarn that burns out when the furnace is operated. For example, natural organic yarns such as hemp and cotton and synthetic organic yarns such as rayon, acetate and nylon can be used. Of course, these blended yarns may be used.
【００２１】燃性糸３は、充填物１の外側に網状（メッ
シュ状）に配置するのが好ましい。燃性糸３の交点は、
固定しても良いし、固定しなくても良い。網目の形状は
正方形、菱形、その他の形状にすることができる。The flammable yarn 3 is preferably arranged in a net shape (mesh shape) outside the filler 1. The intersection of the flammable yarn 3 is
It may be fixed or not fixed. The shape of the mesh can be square, rhombic, or any other shape.
【００２２】無機繊維材２の表面積に対して網状の燃性

十分でなく、充填材が抜け落ちる危険があり、また、５
％未満の場合には充填材１の均一な圧縮及び形状保持が
困難になるためである。It is desirable that the ratio of the net-like fuel yarn 3 to the surface area of the inorganic fiber material 2 be set to 5 to 60%. The reason is that if the occupied area of the flammable yarn 3 is larger than 60%, the connection between the block fiber and the filler fiber is not sufficient, and there is a risk that the filler may fall off.
%, It is difficult to uniformly compress and maintain the shape of the filler 1.

ープが好都合である。As shown in FIG. 1, tape-like members 4 are arranged near both ends of the filler 1. Tape member 4
Can also be arranged on the end face of the filler 1. Similarly to the holding member, the tape-shaped member 4 is formed of a material that is burned out when the furnace is operated. For example, a tape, paper,
An adhesive tape obtained by applying an adhesive to a vinyl resin or other tape is convenient.

業を容易にすると共に、ブロックの保護にも役立つ。FIG. 2 is a view showing a construction state of a furnace wall using the filler 1 shown in FIG. A large number of studs 8 are welded to the furnace shell 7. A metal substrate for attaching the block to the furnace shell 7 is provided on a surface of the inorganic fiber block 5 on the furnace shell side, and a through hole is formed in the metal substrate.
A paper tube 6 is inserted into the center of the block 5, and a cylindrical mounting hole (space) is formed. The paper tube 6 facilitates the mounting operation and also helps protect the block.

At this time, the stud 8 of the furnace shell 7 is penetrated through the through hole of the metal base of the block 5. Then, the nut 9 is screwed into the stud 8 to fix the metal substrate to the furnace shell 7. At this time, a nut is fastened by inserting a tool from the mounting hole.
【００２６】次に、ブロック５と同じ材質の充填材１を
取付穴内に充填する。挿入する充填材１は、取付穴の深
さより１０〜３０ｍｍ程度（５％〜１５％程度）長いも
のを使用することが好ましい。Next, a filler 1 of the same material as that of the block 5 is filled in the mounting hole. It is preferable to use a filler 1 to be inserted that is longer by about 10 to 30 mm (about 5% to 15%) than the depth of the mounting hole.

体が縮小する場合には、前記効果がさらに大きくなる。The filler 1 is compressed in the radial direction in advance, and is further compressed in the axial direction upon insertion. For this reason,
When the holding member 3 is burned out by the operation of the furnace, the connection between the fibers of the block and the fibers of the filler is further ensured. Therefore, good heat insulating properties can be obtained, and the filler 1 can be reliably prevented from falling off. Further, when the mounting hole itself is reduced by removing the paper tube 6, the above effect is further enhanced.

The column was cut into a size of m to obtain a columnar material (inorganic fiber material). While compressing the four sides of this columnar material of 30 × 220 mm with 0.5 mm diameter cotton yarn, the yarn is covered in a mesh shape in a manner that the yarns are almost orthogonal, and both ends are wound with a vinyl resin adhesive tape to form a columnar inorganic fiber. A porous filler was obtained. The filler had a diameter of about 24 mm and a length of 220 mm, with an average yarn spacing of about 5 mm.

After filling, the paper tube was pulled out, and the protruding portion of the filler was pushed into the hole. The time required for this filling operation was about one-fifth of the conventional method for filling bulk or blanket. Thereafter, when the inside of the furnace was heated, the cotton yarn and the tape were burned out, the filler was in close contact with the block, and there was no dropout.

け落ちが防止できる。According to the first aspect of the present invention, since the filling operation of the inorganic fiber block into the mounting hole of the inorganic fiber block is simple, the work efficiency can be greatly improved. The working time can be reduced, for example, to about one-fifth as compared with the conventional bulk or blanket filling. In addition, since the compatibility between the inorganic fiber block and the filler is good, good heat insulating properties can be obtained and the filler can be prevented from falling off.

い。In the furnace according to the second aspect of the present invention, since the homogeneous filler is well blended with the block, the entire block has uniform characteristics, is excellent in heat insulation characteristics, and does not fall off the filler.
Therefore, the service life is longer than that of a furnace using a conventional filler.
