Description
【０００１】[0001]
本考案は、無機繊維質不定形耐火物を支持部材によって炉殻に取付ける構成の 炉壁支持構造体に関する。 The present invention relates to a furnace wall support structure having a structure in which an inorganic fibrous amorphous refractory is attached to a furnace shell by a support member.
【０００２】[0002]
無機繊維質不定形耐火物は、品質の向上及び製造・施行技術の急速な進歩にと もない、使用頻度が増加する傾向にある。熱処理炉等に用いられる炉壁支持構造 体は、無機繊維質不定形耐火物を支持部材によって炉殻の内側に支持・固定する 構成になっている。 Inorganic fibrous amorphous refractories tend to be used more and more due to the improvement of quality and rapid progress of manufacturing and implementation technology. The furnace wall support structure used in heat treatment furnaces, etc., has a structure in which an inorganic fibrous amorphous refractory is supported and fixed inside the furnace shell by a support member.
【０００３】 一般に、高温用の炉の場合には耐火煉瓦製の支持部材が用いられ、比較的低温 の用途には金属製の支持部材が用いられる。Generally, in the case of a high temperature furnace, a refractory brick support member is used, and in a relatively low temperature application, a metal support member is used.
【０００４】 金属製の支持部材としてはＹ型、Ｌ型、棒状、板状と多種多用の金属部材が用 いられるが、その周囲には所定の厚さの膨脹代を設ける必要がある。すなわち、 施工時に支持部材の周囲にビニールテープを巻き付けたり、タールを塗布したり するのである。Various types of metal members such as Y-shaped, L-shaped, rod-shaped, and plate-shaped metal members are used as the metal support member, but it is necessary to provide an expansion margin of a predetermined thickness around the metal member. That is, vinyl tape is wrapped around the support member or tar is applied during construction.
【０００５】 一方、耐火煉瓦製の支持部材としては、四角柱または四角錐台状に凹凸を付し た高アルミナ煉瓦が用いられることが多い。耐火煉瓦製の支持部材の場合にも、 同様の膨脹代が必要である。また、不定形物からの水分の吸収を防止する防水対 策も兼ねて、耐火煉瓦製の支持部材には、施工の際にタールや樹脂等を塗布する のが一般的である。On the other hand, as the supporting member made of refractory brick, a high alumina brick having irregularities in the shape of a quadrangular prism or a truncated pyramid is often used. A similar expansion allowance is required for refractory brick support members. In addition, it is common to apply tar, resin, etc. to the supporting member made of refractory bricks at the time of construction, also as a waterproof measure to prevent absorption of moisture from irregular shaped objects.
【０００６】[0006]
しかしながら、膨脹代の厚みが適当でない場合には、支持部材と不定形耐火物 の熱膨張差を完全に吸収できない。他方、支持金物や支持煉瓦は、不定形耐火物 に比べて熱伝導率が大きい。このため、加熱冷却時に構造体に応力が発生して、 亀裂、脱落やガスリーク等が生じる恐れもある。 However, if the thickness of the expansion margin is not appropriate, the difference in thermal expansion between the support member and the amorphous refractory cannot be completely absorbed. On the other hand, supporting hardware and bricks have higher thermal conductivity than irregular refractory materials. Therefore, stress may be generated in the structure during heating and cooling, which may cause cracking, falling off, gas leakage, or the like.
【０００７】 このような問題の対策として、従来は専ら支持体に膨脹代を設けることが行わ れてきたが、この方法は手間がかかる割には効果が小さく、亀裂、脱落、ガスリ ーク等を完全に防止することができなかった。また、支持体から逃げる熱量も大 きく、従来の炉壁構造体は省エネの面でも問題があった。Conventionally, as a countermeasure against such a problem, an expansion allowance has been provided exclusively on the support, but this method is time-consuming, but the effect is small, and cracks, falling off, gas leaks, etc. Could not be completely prevented. In addition, the amount of heat that escapes from the support is large, and the conventional furnace wall structure also had a problem in terms of energy saving.
【０００８】 このような問題点に鑑み、本考案は、手間がかかる膨脹代を支持部材に設ける 必要がなく炉壁の施行が簡単であり、しかも不定形耐火物に亀裂、脱落、ガスリ ーク等が発生せず、従って熱損失の少ない炉壁構造体を提供することを目的とし ている。In view of the above problems, the present invention does not require a troublesome expansion allowance in the supporting member, the furnace wall is easy to implement, and cracks, omissions, and gas leaks occur in the amorphous refractory. Therefore, the objective is to provide a furnace wall structure with less heat loss.
【０００９】[0009]
本考案は前述の課題を解決したものであり、第一考案は、無機繊維質不定形耐 火物（４）を支持部材によって炉殻（５）に取付ける構成の炉壁支持構造体にお いて、断面が丸みをおびた柱状の支持煉瓦（１）を支持部材として用い、支持煉 瓦（１）は見掛気孔率が５０〜９０％の断熱煉瓦であることを特徴とする炉壁支 持構造体を要旨としている。 The present invention solves the above-mentioned problems, and the first invention is a furnace wall support structure configured to attach an inorganic fiber amorphous refractory (4) to a furnace shell (5) by a supporting member. A furnace wall support characterized in that a pillar-shaped support brick (1) having a round cross section is used as a support member, and the support brick (1) is an insulating brick with an apparent porosity of 50 to 90%. The structure is the main point.
【００１０】 また、第二考案は、無機繊維質不定形耐火物（４）を支持部材によって炉殻（ ５）に取付ける構成の炉壁支持構造体において、支持部材として無機繊維質の支 持紐（７）を用い、支持紐（７）の所定部分（３）を炉殻に固定し、別の部分を 無機繊維質不定形耐火物（４）内に埋設してこれを支持する構成にしたことを特 徴とする炉壁支持構造体を要旨としている。A second invention is a furnace wall support structure in which an inorganic fibrous amorphous refractory material (4) is attached to a furnace shell (5) by a supporting member, and an inorganic fiber supporting cord is used as the supporting member. (7) was used to fix a predetermined part (3) of the support cord (7) to the furnace shell, and another part was embedded in the inorganic fiber amorphous refractory (4) to support it. The main feature is the furnace wall support structure.
【００１１】[0011]
第一考案では、断熱材または発砲剤等によって、支持煉瓦１の見掛気孔率を所 定の値に調整し、支持煉瓦１の熱膨張率及び熱伝導率を小さくすることができる 。断熱材または発砲剤等の含有率を適宜調整することにより、支持煉瓦１と不定 形耐火物の熱膨張率及び熱伝導率の差を小さくすることも可能である。さらに、 支持煉瓦１の断面形状が丸みを帯びているので、仮に不定形耐火物４に応力が発 生した場合にも、その応力が特定の場所に集中することがない。 In the first invention, the apparent porosity of the supporting brick 1 can be adjusted to a predetermined value by using a heat insulating material or a foaming agent, and the thermal expansion coefficient and the thermal conductivity of the supporting brick 1 can be reduced. It is also possible to reduce the difference between the coefficient of thermal expansion and the coefficient of thermal conductivity of the supporting brick 1 and the amorphous refractory by appropriately adjusting the content of the heat insulating material or the foaming agent. Furthermore, since the cross-sectional shape of the supporting brick 1 is rounded, even if stress is generated in the irregular refractory material 4, the stress will not be concentrated in a specific place.
【００１２】 第二考案では、無機繊維の支持紐７を不定形耐火物４と同じくセラミックス質 で構成することができ、従って両者の熱伝導率の差を充分に小さくすることがで きる。さらに、無機繊維の支持紐７は断面積が小さく柔軟性に富んでいる。この ため、加熱や冷却の過程で不定形耐火物に多大な応力が発生することはない。ま た、支持紐７を通して炉外へ逃げる熱量も少なくなる。In the second invention, the support string 7 made of inorganic fiber can be made of the same ceramic material as the amorphous refractory 4, and therefore the difference in thermal conductivity between the two can be made sufficiently small. Further, the inorganic fiber support cord 7 has a small cross-sectional area and is highly flexible. Therefore, a large amount of stress does not occur in the amorphous refractory during the heating or cooling process. Also, the amount of heat that escapes through the support cord 7 to the outside of the furnace is reduced.
【００１３】[0013]
以下、図面を参照して本考案の実施例を説明する。図１は本考案に使用する支 持煉瓦を示す斜視図、図２は図１の支持煉瓦を用いた炉壁構造体の第一実施例を 示す斜視図である。 Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view showing a supporting brick used in the present invention, and FIG. 2 is a perspective view showing a first embodiment of a furnace wall structure using the supporting brick of FIG.
【００１４】 第１実施例 炉壁支持構造体６は、無機繊維質不定形耐火物４を支持煉瓦１によって炉殻５ に取付ける構成になっている。[0014]First embodiment The furnace wall support structure 6 is configured such that the inorganic fiber amorphous refractory 4 is attached to the furnace shell 5 by the support brick 1.
【００１５】 支持煉瓦１は円柱状または円錐台状の断熱煉瓦である。断熱煉瓦としては、例 えば、軽量シャモット、バブルアルミナ等の多孔質軽量骨材，又は、岩錦、スラ グウール、石錦、セラミック繊維、炭素繊維等の無機繊維を含むものが使用でき る。この他に、原料に発砲剤又は有機物の添加剤を加えて作った断熱煉瓦も使用 可能である。The support brick 1 is a heat insulating brick having a columnar shape or a truncated cone shape. As the heat insulating brick, for example, a lightweight lightweight chamotte, a porous lightweight aggregate such as bubble alumina, or a material containing inorganic fibers such as Iwaniki, slag wool, stone brocade, ceramic fiber, and carbon fiber can be used. In addition to this, it is also possible to use insulating bricks made by adding foaming agents or organic additives to the raw materials.
【００１６】 断熱材または添加剤の量は、支持煉瓦１全体の見掛気孔率が５０〜９０％とな るようにする。その理由は、支持煉瓦１全体の気孔率が５０％未満の場合には、 断熱材を含有させる効果が十分に得られず、反対に気孔率が９０％を超える場合 には、支持煉瓦１の強度に問題が生じるからである。気孔率は、さらに望ましく は５５〜７０％の範囲に調整する。使用する断熱材および添加剤の種類や含有割 合は、不定形耐火物４の特性により適宜決めることができる。The amount of the heat insulating material or the additive is such that the apparent porosity of the entire supporting brick 1 is 50 to 90%. The reason is that when the porosity of the whole supporting brick 1 is less than 50%, the effect of including the heat insulating material cannot be sufficiently obtained, and conversely, when the porosity exceeds 90%, This is because problems occur in strength. The porosity is more preferably adjusted in the range of 55 to 70%. The type and content ratio of the heat insulating material and the additive to be used can be appropriately determined according to the characteristics of the amorphous refractory material 4.
【００１７】 不定形耐火物４としては、既知のキャスタブル耐火物やプラスチック耐火物等 を用いることができる。これらの不定形耐火物は、粒状耐火物を組み合わせたも のの他に、セラミック繊維と高アルミナ質耐火骨材及びアルミナ質結合材を適量 組み合わせた無機繊維質不定形耐火物等でも良い。As the amorphous refractory material 4, a known castable refractory material, a plastic refractory material, or the like can be used. These amorphous refractories may be a combination of granular refractories, or an inorganic fibrous amorphous refractory in which an appropriate amount of ceramic fibers, high alumina refractory aggregate and alumina binder are combined.
【００１８】 壁殻５の内面の所定位置には、支持煉瓦１を壁殻５に固定するための取付部材 ９が設けられている。支持煉瓦１の固定部３に取付部材９を係合させることによ って、支持煉瓦１を炉殻５に固定する。支持煉瓦１の取付け方法は、他の方法で も良い。An attachment member 9 for fixing the support brick 1 to the wall shell 5 is provided at a predetermined position on the inner surface of the wall shell 5. The supporting brick 1 is fixed to the furnace shell 5 by engaging the mounting member 9 with the fixing portion 3 of the supporting brick 1. The method of attaching the support brick 1 may be another method.
【００１９】 支持煉瓦１の形状、寸法などは、炉壁構造体の施行条件、施行箇所、施行厚さ 及び炉の仕様などによって適宜設定することが望ましい。支持煉瓦の形状は断面 が丸みをおびた形状にする。支持煉瓦は前述したように、円柱状や円錐台状に形 成することができる。円柱状または円錐台状とは円柱、円錐台に類似の形状も含 むものとする。断面が円や楕円に近く、明確な角部を持たない丸みのある滑らか なものであればよい。It is desirable that the shape, size, etc. of the supporting brick 1 be appropriately set according to the working conditions, working location, working thickness of the furnace wall structure, specifications of the furnace, and the like. The shape of the supporting brick shall be round in cross section. The support brick can be formed in a cylindrical shape or a truncated cone shape as described above. The columnar shape or the truncated cone shape includes a columnar shape and a shape similar to the truncated cone shape. It is sufficient if the cross section is close to a circle or an ellipse and has a rounded and smooth surface with no distinct corners.
【００２０】 支持煉瓦１の一端には、取付け用の固定部３が設けてあり、固定部３は炉殻５ の取付部材９に係合可能である。支持煉瓦１の外周には、不定形耐火物４を支持 するための凹部２が設けてあるが、支持煉瓦１の形状が円錐台状の場合には必ず しも凹部２を設けなくてよい。凹部２は、線状の溝や点状の窪み等であり、不定 形耐火物４に係合してその支持に役立つ。ただし、支持煉瓦１の周面と凹部２の 境界部は明確な角部を持たない丸味のある滑らかなものであることが望ましい。A fixing portion 3 for attachment is provided at one end of the supporting brick 1, and the fixing portion 3 is engageable with the attachment member 9 of the furnace shell 5. Although a concave portion 2 for supporting the irregular refractory material 4 is provided on the outer periphery of the supporting brick 1, the concave portion 2 does not necessarily have to be provided when the supporting brick 1 has a truncated cone shape. The concave portion 2 is a linear groove, a dot-shaped depression, or the like, and engages with the irregular refractory material 4 to help support it. However, it is desirable that the boundary between the peripheral surface of the supporting brick 1 and the recess 2 be round and smooth without any distinct corners.
【００２１】 第２実施例 次に、図３を参照して本考案の炉壁構造体の第２実施例を説明する。 Second Embodiment Next, a second embodiment of the furnace wall structure of the present invention will be described with reference to FIG.
【００２２】 図３の炉壁構造体は、無機質繊維の支持紐７を用いて無機繊維質不定形耐火物 ４を炉殻５に取付ける構成になっている。The furnace wall structure shown in FIG. 3 has a configuration in which the inorganic fiber amorphous refractory 4 is attached to the furnace shell 5 by using the inorganic fiber support cord 7.
【００２３】 無機質繊維の支持紐７は、耐熱性を有し、柔軟性に富みかつ引張強度の大きい 細長い形状の紐状部材である。これらの条件に適合する支持紐７としては、例え ばガラスウール、岩綿、スラグウール、石綿、セラミック繊維、アルミナ繊維、 炭素繊維等をヤーン状、ロープ状、テープ状としたものがある。The inorganic fiber support cord 7 is a long and slender cord-shaped member having heat resistance, rich flexibility and high tensile strength. Examples of the support cords 7 that meet these conditions include glass wool, rock wool, slag wool, asbestos, ceramic fibers, alumina fibers, carbon fibers, etc., which are yarn-shaped, rope-shaped, or tape-shaped.
【００２４】 支持紐７は、その大部分を不定形耐火物４の内部に埋め込むようにする。埋め 込む方法としては、耐火物を流し込む枠にあらかじめ固定しておくとよい。埋め 込んだ支持紐７には、途中に例えばコブ状の結び目１０を設けたり、炉の内側に 閉じたＵ字状やＶ字状の部分を設けることが望ましい。これにより、不定形耐火 物をより一層確実に支持することができる。また、支持紐７を図３に示すように 、二次元または三次元の網状としても良い。Most of the support string 7 is embedded in the amorphous refractory material 4. As a method of embedding, it is advisable to fix the refractory in a frame beforehand. The embedded support cord 7 is preferably provided with, for example, a knot-shaped knot 10 or a closed U-shaped or V-shaped portion inside the furnace. This makes it possible to more reliably support the irregular refractory material. Further, the support cord 7 may have a two-dimensional or three-dimensional mesh shape as shown in FIG.
【００２５】 支持紐７の一部は炉外側に配置して固定部３とし、炉殻に結び付けるか、引っ 掛けるなどして固定する。さらに、支持紐７の一部を炉の内側にも飛び出させて 突出部８を設けておくと、プレハブ工法で炉壁構造体を製作および移動する際の 取り扱いに都合が良い。A part of the support cord 7 is arranged outside the furnace to form the fixing portion 3, which is fixed to the furnace shell by being tied or hooked. Furthermore, if a part of the support cord 7 is also protruded to the inside of the furnace to provide the protruding portion 8, it is convenient for handling when manufacturing and moving the furnace wall structure by the prefabricated method.
【００２６】 このように構成した第２実施例の炉壁構造体を試験炉に組み込み、１２００℃ で１６８時間（一週間）加熱試験をしたところ、炉壁に亀裂、脱落が生じたり、 ガスがリークするなどの不具合は見られなかった。When the furnace wall structure of the second example configured as described above was installed in a test furnace and subjected to a heating test at 1200 ° C. for 168 hours (one week), cracks and omissions occurred in the furnace wall, and gas was generated. There were no problems such as leaks.
【００２７】[0027]
第一考案の炉壁構造体においては、支持煉瓦が断熱煉瓦であるため、支持煉瓦 の熱伝導率を小さくし断熱性を大きくすることができる。従って、炉の熱効率を 向上することができる。また、支持煉瓦に断熱材を含有させることによって、不 定形耐火物と支持煉瓦の熱膨脹の差を小さくすることができ、さらに支持煉瓦は 断面が丸味のある形状であるため応力が集中せず、炉壁に亀裂や脱落が生じるこ とがなく、ガスリークも防止できる。 In the furnace wall structure of the first invention, since the supporting brick is the heat insulating brick, the thermal conductivity of the supporting brick can be reduced and the heat insulating property can be increased. Therefore, the thermal efficiency of the furnace can be improved. In addition, by including a heat insulating material in the supporting brick, the difference in thermal expansion between the amorphous refractory and the supporting brick can be reduced, and since the supporting brick has a rounded cross section, stress is not concentrated, The furnace wall will not be cracked or fallen off, and gas leakage can be prevented.
【００２８】 第二考案の炉壁構造体で用いる無機繊維の支持紐は、断面積が小さく柔軟性が あるので、加熱冷却の際にも不定形耐火物を損傷することがない。また、支持紐 の一部を炉内側に飛び出させておくとプレハブ工法の際に、取り扱いに便利であ る。Since the inorganic fiber support cord used in the furnace wall structure of the second invention has a small cross-sectional area and flexibility, it does not damage the amorphous refractory during heating and cooling. In addition, it is convenient to handle the prefabricated method if a part of the support cord is made to project inside the furnace.
【００２９】 いずれの場合にも、支持体にタール、樹脂などを塗布する必要が全くないため に炉壁組立て時の作業性が向上する。In any case, since it is not necessary to coat the support with tar, resin, etc., workability in assembling the furnace wall is improved.
