Description
【考案の詳細な説明】 この考案は炉壁冷却装置の改良に関するものである。[Detailed explanation of the idea] This invention relates to an improvement of the furnace wall cooling system.
たとえば、高炉その他の溶鉱炉では、鉄皮およびその内
側に順次に配設したステーブ、煉瓦などの断熱耐火物で
炉壁を構威し、そしてそれらのステーブ、耐火物などに
よって炉内から炉外方向への熱伝達量を低減させること
により鉄皮の保護を図ることが一般的である。For example, in blast furnaces and other blast furnaces, the furnace wall is made up of an iron shell and insulating refractories such as staves and bricks arranged sequentially inside the shell, and these staves, refractories, etc. It is common practice to protect the steel shell by reducing the amount of heat transferred to it.
しかしながら、耐火物は一般に短期間で脱落してしまう
傾向にあり、その脱落後にはステーブだけによって断熱
ならびに鉄皮の冷却を行わなければならず、このためス
テーブの寿命が鉄皮の寿命に極めて大きな影響を与える
こととなる。However, refractories generally tend to fall off in a short period of time, and after they fall off, insulation and cooling of the shell must be carried out only by the stave, and for this reason, the life of the stave is significantly longer than the life of the shell. This will have an impact.
そこで第１図に示すように、鉄皮ａの内側に、通常の平

ステーブｂ′の支持が剛性に乏しく、ステーブｂ′の比
較的早期の脱落を阻止し得ない問題があった。Therefore, as shown in Fig. 1, normal flat staves b and b' are arranged in a multi-layered manner (two layers in the illustrated example) inside the steel skin a, and a refractory material C is further stacked on the inside of the stave. ! jI
! After the IJC falls off, first, only stave b' located inside the furnace is exposed inside the furnace, and then stave b'
A proposal has been made to reduce the amount of heat transferred to the shell by exposing stave b in the furnace when stave b is damaged, but in such a cooling system, each stave b and b' is Since it is customary for each stave b' to be individually attached to the steel shell by a fixing means, the support of the stave b' in particular lacks rigidity, and there is a problem in that it is not possible to prevent the stave b' from falling off relatively early.
この考案は、ステーブを炉壁に多層状に配置した場合に
おいて、とくに炉内側のステーブを堅固に支持すること
によって、そのステーブの早期の脱落を防止して鉄皮の
充分な保護を行い得る冷却装置を提供するものである。This idea is designed to provide sufficient protection for the steel shell by firmly supporting the staves inside the furnace and preventing them from falling off at an early stage when the staves are arranged in multiple layers on the furnace wall. It provides equipment.
以下にこの考案の実施例を図面に基いて説明する。Examples of this invention will be described below based on the drawings.
第２図ａはこの考案の実施例を示す断面図であり、第２
図すは同一の実施例を鉄皮を除去して示す正面図である
。Figure 2a is a sectional view showing an embodiment of this invention;
The figure is a front view of the same embodiment with the iron shell removed.
図中１は鉄皮、２，３はそれぞれ鉄皮の内側に位置する
鉄皮側ステーブおよび炉内側ステーブ、４はステーブの
さらに内側に積み重ねた耐火物であり、これらの鉄皮１
、ステーブ２，３、耐火物４によって炉壁を構成する。In the figure, 1 is the steel shell, 2 and 3 are the shell side stave and the furnace inner stave located inside the steel shell, and 4 is the refractory stacked further inside the stave.
, staves 2, 3, and refractory 4 constitute a furnace wall.
ここで鉄皮側ステーブ２および炉内側ステーブ３は互い
に分離されたそれぞれ別個の冷却管路５および６を有し
ており、鉄皮のすぐ内側に配置したステーブ２はボルト
７および冷却管路５によって鉄皮１に支持され、そして
炉内側ステーブ３は、ステーブ２，２間に貫通させたボ
ルト８および冷却管路６によって鉄皮１に支持される。Here, the shell-side stave 2 and the furnace-side stave 3 have separate cooling pipes 5 and 6, respectively, which are separated from each other, and the stave 2 located just inside the shell has a bolt 7 and a cooling pipe 5. The furnace inner stave 3 is supported by the steel shell 1 by bolts 8 and cooling pipes 6 passed through between the staves 2 and 2.
しかしながら、このような支持だけではとくに鉄皮１か
らの離間距離の大きい炉内側ステーブ３はステーブ自重
および炉内の内容物重量に充分対抗することができず、
早期に脱落してしまうため、この考案では鉄皮側ステー
１２の炉内側表面の中央部に、横方向へ延在する突条９
を設け、各突条間に炉内側ステーブ３を配設することに
より、ボルト８および冷却管路６のみならず鉄皮側ステ
ーブ２によってもまた炉内側ステーブ３を支持してその
早期の脱落を防止する。However, with such support alone, the stave 3 inside the furnace, which has a large distance from the shell 1, cannot sufficiently counter the weight of the stave itself and the weight of the contents in the furnace.
To prevent this from falling off early, this design has a protrusion 9 extending laterally in the center of the furnace inner surface of the shell side stay 12.
By providing a furnace inner stave 3 between each protrusion, the furnace inner stave 3 is supported not only by the bolts 8 and the cooling pipe line 6 but also by the shell side stave 2 to prevent it from falling off at an early stage. To prevent.
ここで各突条９は、二個の炉内側ステーブ３の上端面と
下端面との間に挾まれるので、それらのステー１３によ
ってその冷却を十分に担保される。Here, since each protrusion 9 is sandwiched between the upper end surface and the lower end surface of the two furnace inner staves 3, its cooling is sufficiently ensured by the stays 13.
従って、突条９は炉内側へ突出しているにもかかわらず
、炉内側熱負荷から有効に保護され、その機能は長期間
にわたって維持される。Therefore, although the protrusions 9 protrude toward the inside of the furnace, they are effectively protected from the heat load inside the furnace, and their functions are maintained for a long period of time.
なお、炉内側ステーブ３はステーブ２，２間を通るボル
ト８にて鉄皮に固定されているので、その脱落がステー
１２に直接的な何の影響をももたらすことがない他、ス
テーブ２の強度を低下させることがなく、しかもステー
ブ２の製造を容易ならしめる。Furthermore, since the furnace inner stave 3 is fixed to the steel shell by bolts 8 passing between the staves 2, its falling off will not have any direct effect on the stay 12, and the stave 2 The strength of the stave 2 is not reduced, and the stave 2 can be manufactured easily.
ここで、突条９の突出長さに関し、複数の突条９のうち

火物４内まで突出する必要があり、また、残りの突条９
は、少なくとも炉内側ステーブ３を支持するに足るだけ
突出する必要がある。Here, regarding the protruding length of the protrusions 9, necessary ones of the plurality of protrusions 9 not only support the furnace inner stave 3 but also support the refractories 4 and prevent them from falling off. In order to effectively prevent
needs to protrude at least enough to support the furnace inner stave 3.
また、ステーブ２，３の相対位置は、第２図すに示すよ
うに、４個の鉄皮側ステーブ２の相互に隣接する隅角部
にステーブ３の中央部が位置するように配置することが
、炉壁の均等な冷却、裏風の防止などのために好適であ
る。Furthermore, the relative positions of the staves 2 and 3 should be such that the center portion of the stave 3 is located at the mutually adjacent corners of the four steel shell side staves 2, as shown in Fig. 2. However, it is suitable for uniform cooling of the furnace wall and prevention of back draft.
なお、突条９は必ずしも鉄皮側ステーブ２の全てに設け
る必要はなく、たとえば上下方向に一個もしくは二個お
きに設けることも可能である。Note that the protrusions 9 do not necessarily need to be provided on all of the steel shell side staves 2, and may be provided on every other or every two staves in the vertical direction, for example.
従って、この考案によれば鉄皮側ステーブの中央部に設

脱落を有効に防止することが可能となり、また、鉄皮側
ステーブの比較的冷却効率の低い各隅部を炉内側ステー
ブの中央部にて冷却して鉄皮を有利に保護することが可
能となる。Therefore, according to this invention, since the furnace inner stave can be supported by the protrusion provided at the center of the shell side stave, the attachment strength of the furnace inner stave can be sufficiently increased to effectively prevent it from falling off. In addition, each corner of the stave on the shell side, where cooling efficiency is relatively low, can be cooled at the center of the stave on the furnace side, thereby advantageously protecting the shell.
しかも、鉄皮側ステーブの所要個数の突条を耐火物内ま
で突出させ、その突条で耐火物をも支持することにより
、耐火物の早期の脱落もまた有効に防止されることにな
る。Furthermore, by making the required number of protrusions of the stave on the skin side protrude into the refractory and supporting the refractory with the protrusions, early falling off of the refractory can also be effectively prevented.
なお、各突条はそれらの間に配置した炉内側ステーブに
て冷却されるので、突条による上述した作用効果は長期
にわたって維持されることになる。Note that since each of the protrusions is cooled by the furnace inner stave disposed between them, the above-mentioned effects of the protrusions are maintained over a long period of time.
