Description

本発明は、コークス炉炭化室の煉瓦を熱間で積替える際に使用する側面防熱装置、及びこの側面防熱装置を構成する側面防熱板を炭化室内に設置する方法に関するものである。   TECHNICAL FIELD The present invention relates to a side heat insulating device used when a brick in a coke oven carbonization chamber is hot-loaded, and a method of installing a side heat insulating plate constituting the side heat insulating device in the carbonizing chamber.

コークス炉は、主に珪石煉瓦で構成された構造体であり、石炭を装入して乾留する炭化室と、ガス燃焼により乾留のための熱を供給する機能を有する燃焼室が、交互に重層する構造を有している。   A coke oven is a structure mainly composed of silica brick, and a carbonization chamber in which coal is charged and carbonized and a combustion chamber having a function of supplying heat for carbonization by gas combustion are alternately layered. It has the structure to do.

コークス炉の寿命は３０〜５０年と言われており、この寿命に至るまでの長年の操業により、図９に示すように、炭化室１の炉壁に破孔１ａのような経年劣化が発生する。なお、図９中の２は燃焼室を示す。   It is said that the life of the coke oven is 30 to 50 years, and as a result of many years of operation up to this end of life, as shown in FIG. To do. In addition, 2 in FIG. 9 shows a combustion chamber.

このように経年劣化した部分への対応方法として、劣化した煉瓦の表面に耐火材を吹き付ける溶射補修や、劣化した煉瓦を新しい煉瓦と差し替える煉瓦積替補修を実施している。なお、煉瓦積替補修は、一般にはコークス炉が高温状態のままで行われるために、熱間煉瓦積替補修とか、単に熱間補修などと称されている。   As a method for dealing with such deteriorated parts, thermal spray repair that sprays refractory material on the surface of deteriorated bricks and brick replacement repair that replaces deteriorated bricks with new bricks are carried out. Brick transshipment repair is generally performed while the coke oven is kept in a high temperature state, and is therefore referred to as hot brick transshipment repair or simply hot repair.

このうち、煉瓦積替補修では、炭化室内で作業する作業者の作業環境（主に暑熱対策）確保のため、煉瓦積替補修を行わない非補修部の炭化室炉壁に、耐火物で構成される防熱板を設置し、高温の炉壁からの輻射熱から作業者を防護している。   Of these, the brick transshipment repair consists of a refractory material in the carbonization chamber furnace wall of the non-repaired part where brickwork transshipment repair is not performed in order to ensure the working environment (mainly heat countermeasures) for workers working in the carbonization chamber. A heat shield is installed to protect workers from radiant heat from the high temperature furnace wall.

コークス炉熱間補修時の防熱板の設置方法として、図１０に示すように、炭化室１内に奥側防熱板３と側面防熱板４を設置して補修部Ａと非補修部Ｂを区分し、非補修部Ｂから補修部Ａへの熱の移動を遮る方法が提案されている（特許文献１）。なお、図１０（ａ）は平面方向から見た断面図であり、紙面左右方向を炉長方向、紙面上下方向を炉幅方向と称し、紙面右側が炉外、紙面左側が炉内であり奥側と称している。   As shown in FIG. 10, as a method of installing the heat insulating plate during hot repair of the coke oven, as shown in FIG. And the method of interrupting | blocking the heat transfer from the non-repair part B to the repair part A is proposed (patent document 1). FIG. 10A is a cross-sectional view as seen from the plane direction. The left-right direction on the paper is referred to as the furnace length direction, the up-down direction on the paper is referred to as the furnace width direction, the right side of the paper is outside the furnace, and the left side of the paper is inside the furnace. It is called the side.

前記奥側防熱板３は、非補修部Ｂである炭化室１の奥側から補修部Ａ側への熱移動を遮るために設置され、前記側面防熱板４は、炭化室１内の補修部Ａに対面する非補修部Ｂである炉壁からの熱移動を遮るために設置されている。本明細書では、奥側防熱板３と側面防熱板４を総称して「防熱板３，４」とも言う。   The back side heat insulating plate 3 is installed to block heat transfer from the back side of the carbonizing chamber 1 which is the non-repairing portion B to the repairing portion A side, and the side heat insulating plate 4 is a repaired portion in the carbonizing chamber 1. It is installed to block heat transfer from the furnace wall, which is a non-repair part B facing A. In the present specification, the back side heat insulating plate 3 and the side heat insulating plate 4 are collectively referred to as “heat insulating plates 3 and 4”.

防熱板３，４の炭化室１内への挿入方法の概要を図１１に示す。先ず、炭化室１の天井部に 防熱板挿入用のガイド装置である天井吊りガイドレール５を設置する。天井吊りガイドレール５は、天井部の装炭孔１ｂを利用して、装炭孔１ｂの上に吊り架台６を置き、吊り架台６と天井吊りガイドレール５を吊りボルト７ａで接続して、固定ナット７ｂで天井吊りガイドレール５の高さ位置を調整して固定する。   An outline of a method for inserting the heat insulating plates 3 and 4 into the carbonization chamber 1 is shown in FIG. First, a ceiling suspension guide rail 5 which is a guide device for inserting a heat insulating plate is installed on the ceiling portion of the carbonization chamber 1. The ceiling suspension guide rail 5 uses the carbonization hole 1b of the ceiling part, places the suspension frame 6 on the carbonization hole 1b, connects the suspension frame 6 and the ceiling suspension guide rail 5 with the suspension bolts 7a, The height of the ceiling suspension guide rail 5 is adjusted and fixed with the fixing nut 7b.

一方、防熱板３，４には上部に対向配置された対をなす上部ガイドローラ３ａ，４ａが設置されており、この上部ガイドローラ３ａ，４ａを介して天井吊りガイドレール５に懸垂して移動する。防熱板３，４は、事前に炉外の作業台車８内に準備されており、作業台車内レール８ａから天井吊りガイドレール５に乗り移ることで、防熱板３，４を炭化室１内に挿入する。   On the other hand, a pair of upper guide rollers 3a and 4a arranged opposite to each other on the upper sides of the heat insulating plates 3 and 4 are installed. The upper guide rollers 3a and 4a are suspended from the ceiling suspension guide rail 5 and moved. To do. The heat insulating plates 3 and 4 are prepared in advance in the work carriage 8 outside the furnace, and the heat insulating plates 3 and 4 are inserted into the carbonization chamber 1 by transferring from the work carriage inner rail 8 a to the ceiling suspension guide rail 5. To do.

しかしながら、側面防熱板４の重心Ｇは、対をなす上部ガイドローラ４ａを案内する天井吊りガイドレール５の中心線よりも炉幅方向にずれている。その結果、対をなす上部ガイドローラ４ａで吊り下げ状に支持される側面防熱板４は、図１２に実線で示すように傾いてしまう。   However, the center of gravity G of the side heat shield 4 is shifted in the furnace width direction from the center line of the ceiling suspension guide rail 5 that guides the pair of upper guide rollers 4a. As a result, the side heat insulating plate 4 supported in a suspended manner by the pair of upper guide rollers 4a is inclined as shown by a solid line in FIG.

側面防熱板４が傾くので、作業台車内レール８ａから天井吊りガイドレール５への上部ガイドローラ４ａのスム−ズな乗り移りが行えないという不具合があった。   Since the side heat shield 4 is inclined, there is a problem that the smooth transfer of the upper guide roller 4a from the work carriage inner rail 8a to the ceiling suspension guide rail 5 cannot be performed.

また、天井吊りガイドレール５に乗り移った後は、炭化室１内で側面防熱板４が傾いているため、作業者Ｍが まだ暑い炭化室１内に入り、図１３に示すように、側面防熱板４の傾きを直して、側面防熱板４を炭化室１の炉壁面に密着固定させる必要があった。   Further, after the transfer to the ceiling suspension guide rail 5, the side heat insulating plate 4 is inclined in the carbonization chamber 1, so that the worker M enters the still hot carbonization chamber 1, and as shown in FIG. It was necessary to fix the inclination of the plate 4 and to fix the side heat insulating plate 4 in close contact with the furnace wall surface of the carbonizing chamber 1.

特開昭５６−１２５４８１号公報JP 56-125481 A

本発明が解決しようとする問題点は、側面防熱板が作業台車内レールから天井吊りガイドレールに乗り移る際に、上部ガイドローラが天井吊りガイドレールにスム−ズに乗り移ることができないという点である。また、乗り移った後は側面防熱板が傾いているため、作業者が まだ暑い炭化室内部に入り、側面防熱板の傾きを直して、側面防熱板を炉壁面に密着固定させる必要があるという点である。   The problem to be solved by the present invention is that when the side heat shield is transferred from the work carriage inner rail to the ceiling suspension guide rail, the upper guide roller cannot smoothly transfer to the ceiling suspension guide rail. . In addition, since the side heat shields are tilted after the transfer, it is necessary for the worker to enter the still hot carbonization chamber, fix the side heat shields, and fix the side heat shields to the furnace wall. It is.

The main feature is that it consists of

After attaching the ceiling suspension guide rail to the ceiling of the carbonization chamber and the lower guide rail to the bottom of the carbonization chamber,
A predetermined position in the carbonization chamber in a state where the upper side guide roller is guided to the ceiling suspension guide rail, the lower side guide roller is guided to the lower guide rail, and the side side heat insulating plate is supported at two upper and lower positions. Move up. This is the method of installing the side heat insulating plate at the time of hot transshipment in the coke oven carbonization chamber of the present invention.

前記本発明において、下部ガイドレールを、炭化室の炉幅方向に拡幅可能に構成したものとすれば、側面防熱板の炉壁面への密着固定が容易に行えるようになる。   In the present invention, if the lower guide rail is configured to be widened in the furnace width direction of the carbonization chamber, the side heat shield plate can be easily fixed to the furnace wall surface.

この炭化室の炉幅方向に拡幅可能に構成した下部ガイドレールを備えた本発明の側面防熱装置を構成する側面断熱板を、炭化室内の所定位置に設置する場合は、側面防熱板を所定位置まで移動した後、下部ガイドレールを、炭化室の炉幅方向に拡幅し、側面防熱板を非補修炉壁に密着させればよい。   When the side heat insulating plate constituting the side heat insulating device of the present invention having the lower guide rail configured to be widened in the furnace width direction of the carbonizing chamber is installed at a predetermined position in the carbonizing chamber, the side heat insulating plate is set at the predetermined position. Then, the lower guide rail may be widened in the furnace width direction of the carbonization chamber, and the side heat insulating plate may be brought into close contact with the non-repair furnace wall.

本発明では、作業台車内レールから天井吊りガイドレールへの側面防熱板の乗り移りが容易に行えるようにするという目的を、天井部と底部の２箇所で側面防熱板を支持することで実現した。   In the present invention, the purpose of facilitating the transfer of the side heat insulating plate from the work carriage inner rail to the ceiling suspension guide rail is realized by supporting the side heat insulating plate at two places, the ceiling portion and the bottom portion.

本発明は、作業台車内レールから天井吊りガイドレールへの側面防熱板の乗り移り時に、側面防熱板が傾いて抵抗が生じる不具合や、天井吊りガイドレールへの乗り移り後に、炉壁と側面防熱板の間で隙間が発生する不具合に対して検討したものである。   The present invention relates to a problem that the side heat insulating plate is tilted when the side heat insulating plate is transferred from the work carriage inner rail to the ceiling suspension guide rail, and a resistance is generated between the furnace wall and the side heat insulating plate after the transfer to the ceiling suspension guide rail. This is a study for the problem of gaps.

以下、本発明の完成に至るまでの経過と共に、本発明のコークス炉炭化室における熱間積替時の側面防熱装置について説明した後、この側面防熱装置を構成する側面防熱板を炭化室内の所定位置に設置する方法について説明する。   Hereinafter, along with the progress up to the completion of the present invention, the side heat insulating device at the time of hot transfer in the coke oven carbonizing chamber of the present invention will be described, and then the side heat insulating plate constituting the side heat insulating device is set in the carbonizing chamber. A method of installing at the position will be described.

前記の側面防熱板４が天井吊りガイドレール５に乗り移る時の重心による傾き対策として、図１４に示すように、炭化室１の炉幅方向に移動可能なレール４ｂを上部に設けた側面防熱板４を用いる方法が考えられる。   As shown in FIG. 14, as shown in FIG. 14, a side heat insulating plate provided with a rail 4 b that is movable in the furnace width direction of the carbonization chamber 1 is provided as a countermeasure against inclination when the side heat insulating plate 4 is transferred to the ceiling suspension guide rail 5. A method using 4 is conceivable.

この方法では、側面防熱板４の天井吊りガイドレール５への乗り移り時は、側面防熱板４を天井吊りガイドレール５の真下に移動させることで重心による傾きを防止できる。また、設置位置では側面防熱板４をレール４ｂに沿って炉壁に押し付けることが可能であると考えられる。   In this method, when the side heat shield 4 is transferred to the ceiling suspension guide rail 5, the side heat shield 4 can be moved directly below the ceiling suspension guide rail 5 to prevent tilting due to the center of gravity. In addition, it is considered that the side heat insulating plate 4 can be pressed against the furnace wall along the rail 4b at the installation position.

しかしながら、側面防熱板４が炉幅方向に移動自在であるということは、同時に望まなくても側面防熱板４が炉幅方向へ移動する可能性があるということであり、炉壁にしっかりと密着させることが難しい。   However, the fact that the side heat insulating plate 4 is movable in the furnace width direction means that the side heat insulating plate 4 may move in the furnace width direction even if it is not desired at the same time, and is firmly attached to the furnace wall. It is difficult to let

仮に側面防熱板４を炉壁に密着させることが一時的に可能であっても、その後に側面防熱板４が熱膨張した場合には、図１５に示すように、上部に設けたレール４ｂによって側面防熱板４が移動し、炉壁と側面防熱板４との間で隙間が発生することもある。   Even if it is temporarily possible to make the side heat insulating plate 4 closely contact with the furnace wall, if the side heat insulating plate 4 is thermally expanded after that, as shown in FIG. The side heat insulating plate 4 may move, and a gap may be generated between the furnace wall and the side heat insulating plate 4.

従って、炉幅方向に移動可能なレール４ｂを設けた側面防熱板４を用いる方法を採用した場合でも、天井吊りガイドレール５への側面防熱板４の乗り移り直後に、作業者がまだ暑い炭化室１の内部に入って側面防熱板４を炉壁面に密着固定させる必要が生じる。   Therefore, even when the method using the side heat insulating plate 4 provided with the rail 4b movable in the furnace width direction is adopted, immediately after the side heat insulating plate 4 is transferred to the ceiling suspension guide rail 5, the worker is still hot in the carbonization chamber. It is necessary to enter the inside of 1 and to fix the side heat insulating plate 4 in close contact with the furnace wall surface.

そこで、発明者らは、図１に示すように、側面防熱板１１の上部に設けた上部ガイドローラ１１ａに加えて、下部に下部ガイドローラ１１ｂを設けることを考えた。一方、炭化室１には、天井部に天井吊りガイドレール５を設置するのに加えて、底部には、側面防熱板１１の挿入用ガイドである下部ガイドレール１２を、前記下部ガイドレール１２に接触するように設置することとした。   Therefore, the inventors considered providing a lower guide roller 11b in the lower part in addition to the upper guide roller 11a provided in the upper part of the side heat insulating plate 11, as shown in FIG. On the other hand, in the carbonization chamber 1, in addition to installing the ceiling suspension guide rail 5 on the ceiling portion, a lower guide rail 12, which is a guide for inserting the side heat insulating plate 11, is attached to the lower guide rail 12 on the bottom portion. It was decided to install it so that it touched.

このような構成の側面防熱装置を使用すれば、側面防熱板１１は天井吊りガイドレール５で支持されると共に、側面防熱板１１の傾きを下部ガイドレール１１ｂによって防止できるようになる（図２参照）。   If the side heat insulating device having such a configuration is used, the side heat insulating plate 11 is supported by the ceiling suspension guide rail 5, and the inclination of the side heat insulating plate 11 can be prevented by the lower guide rail 11b (see FIG. 2). ).

その際、図２、図３の（ｂ）図に示すように、例えば平行リンク機構によって下部ガイドレール１１ｂの幅を炉幅方向に広げることが可能な構造とすることが望ましい。このような構成とすれば、側面防熱板１１を炭化室１の所定位置に押し込んだ後に、下部ガイドレール１１ｂの拡幅を行えば、容易に炉壁に密着できるようになる（図３参照）。   At that time, as shown in FIG. 2 and FIG. 3B, it is desirable to have a structure in which the width of the lower guide rail 11b can be expanded in the furnace width direction by, for example, a parallel link mechanism. With such a configuration, if the lower guide rail 11b is widened after the side heat insulating plate 11 is pushed into a predetermined position of the carbonization chamber 1, it can be easily adhered to the furnace wall (see FIG. 3).

以下、上記構成の本発明のコークス炉炭化室の熱間積替時の側面防熱装置を用いて、側面防熱板１１を設置する方法を、図４を用いて説明する。   Hereinafter, a method of installing the side heat insulating plate 11 using the side heat insulating device during the hot transfer of the coke oven carbonization chamber of the present invention having the above configuration will be described with reference to FIG.

図４は、炭化室１内に設置した天井吊りガイドレール５を用いて、奥側防熱板３を炭化室１内に押し込んだ後、炭化室１の底部に下部ガイドレール１２を挿入・設置し、その後、側面防熱板１１を炭化室１内に押し込んだ状態を示した図である。   In FIG. 4, using the ceiling suspension guide rail 5 installed in the carbonization chamber 1, the rear heat insulating plate 3 is pushed into the carbonization chamber 1, and then the lower guide rail 12 is inserted and installed at the bottom of the carbonization chamber 1. Then, it is the figure which showed the state which pushed the side heat insulating board 11 into the carbonization chamber 1 after that.

ところで、前記側面防熱板１１は、例えば図３（ｃ）に示すように、鋼製の支持枠１１ｃ、石膏ボード１１ｄ、繊維系断熱材１１ｅで構成されている。このうち、繊維系断熱材１１ｅは可縮可能であり、下部を下部ガイドレール１２の拡幅で強く圧縮することで、上部についても側面防熱板１１と炭化室１の炉壁を密着させることができる。この結果、所定位置において、側面防熱板１１と炉壁の隙間を殆ど無くし、隙間に冷気が入るのを防止することができる。これが本発明の側面防熱板１１の設置方法である。   By the way, as shown in FIG.3 (c), the said side surface heat insulating board 11 is comprised with the steel support frame 11c, the gypsum board 11d, and the fiber-type heat insulating material 11e, for example. Among them, the fiber-based heat insulating material 11e is retractable, and the lower heat-resistant plate 11 and the furnace wall of the carbonizing chamber 1 can be brought into close contact with each other even by compressing the lower portion strongly with the widening of the lower guide rail 12. . As a result, the gap between the side heat insulating plate 11 and the furnace wall is almost eliminated at a predetermined position, and cold air can be prevented from entering the gap. This is the installation method of the side heat insulating plate 11 of the present invention.

上記までの作業で、炭化室１内の非補修部Ｂは断熱養生できたことになるので、翌日まで作業を中断して作業環境が冷えるのを待つ。作業環境が冷えたところで、炭化室１内（作業環境）に作業足場１３を組み立てながら、奥側防熱板３とバックステー１５に溶接固定したフラットバー１４で側面防熱板１１を固定する（図５参照)。この作業により、炭化室１内で補修を実施する作業環境を確保することができたことになる。   The non-repair part B in the carbonization chamber 1 has been adiabatic and cured by the above-described work, so the work is interrupted until the next day and the work environment is cooled. When the working environment is cooled, the side heat insulating plate 11 is fixed by the flat bar 14 welded and fixed to the back heat insulating plate 3 and the backstay 15 while assembling the work scaffold 13 in the carbonization chamber 1 (working environment) (FIG. 5). reference). As a result of this work, the work environment in which the repair is performed in the carbonization chamber 1 can be secured.

ところで、補修範囲が炭化室１の窯口近傍で、炉内に入って行う側面防熱板１１の固定作業の暑熱負荷が小さい場合は、図２、図３に示したように、下部ガイドレール１２に拡幅機能を設けなくても良い。この場合、図６に示すように、拡幅機能をもたない下部ガイドレール１２を用いて側面防熱板１１を挿入し、作業者が炭化室１内に入って側面防熱板１１を固定する。   By the way, when the heat load of the fixing work of the side heat insulating plate 11 performed in the furnace is small in the vicinity of the furnace opening of the carbonization chamber 1 as shown in FIGS. 2 and 3, the lower guide rail 12 is repaired. It is not necessary to provide a widening function. In this case, as shown in FIG. 6, the side heat insulating plate 11 is inserted using the lower guide rail 12 having no widening function, and the worker enters the carbonization chamber 1 and fixes the side heat insulating plate 11.

ちなみに、本発明を適用した場合の作業内容として、下部ガイドレールの拡幅を実施する場合としない場合の各作業に要する時間を図７に示す。   Incidentally, FIG. 7 shows the time required for each operation when the widening of the lower guide rail is performed and when it is not performed as the operation content when the present invention is applied.

発明例１は、下部ガイドレールを使用するものの、側面防熱板を炭化室の炉壁に密着させるための下部ガイドレール拡幅を実施しない場合である。   Invention Example 1 is a case where the lower guide rail is used but the lower guide rail is not widened so that the side heat insulating plate is brought into close contact with the furnace wall of the carbonization chamber.

また、発明例２は、拡幅機能を有した下部ガイドレールを使用した場合で、側面防熱板の天井吊りガイドレールへの乗り移り後、すぐに炭化室の炉壁に側面防熱板を密着させて炭化室の炉壁の冷却を防止した場合である。   Inventive Example 2 is a case where a lower guide rail having a widening function is used, and immediately after the side heat insulating plate is transferred to the ceiling hanging guide rail, the side heat insulating plate is brought into close contact with the furnace wall of the carbonization chamber and carbonized. This is a case where cooling of the furnace wall of the chamber is prevented.

これら発明例１、２では、従来例では不要である下部ガイドレールの炭化室内への挿入に３０ 分を要することになった。しかしながら、側面防熱板が重心で傾くことがなかったため、側面防熱板の天井吊りガイドレールへの乗り移り作業は、従来例では２時間かかったものが、約半分の１．２時間で済ませることができた。   In these Invention Examples 1 and 2, it took 30 minutes to insert the lower guide rail into the carbonization chamber, which is unnecessary in the conventional example. However, since the side heat insulating plate did not tilt at the center of gravity, the transfer work of the side heat insulating plate to the ceiling suspension guide rail took 2 hours in the conventional example, but it can be completed in about half of 1.2 hours. It was.

一方、発明例１では、側面防熱板と炭化室の炉壁の間に隙間があるため、炉壁が冷えないように側面防熱板をすぐに固定する必要がある。側面防熱板の固定作業は、暑熱作業で作業能率が悪いので、従来方法と同様、３．０時間 を要した。   On the other hand, in Invention Example 1, since there is a gap between the side heat shield and the furnace wall of the carbonization chamber, it is necessary to immediately fix the side heat shield so that the furnace wall does not cool. Fixing the side heat shield plate took 3.0 hours as in the conventional method because the work efficiency was poor due to the hot work.

これに対して、発明例２では、側面防熱板の天井吊りガイドレールへの乗り移り後に下部ガイドレールを拡幅（５分以下）し、側面防熱板を炉壁に密着させて炉壁温度の低下を防ぐことができたので、側面防熱板の固定作業を翌日（２日目）に行うことができた。２日目には、作業環境の温度が低下したため、側面防熱板の固定作業を従来の作業方法の１／３ の１時間で終えることができた。   On the other hand, in Invention Example 2, after the side heat shield plate is transferred to the ceiling suspension guide rail, the lower guide rail is widened (5 minutes or less), and the side heat shield plate is brought into close contact with the furnace wall to reduce the furnace wall temperature. As a result, the side heat insulating plate could be fixed on the next day (second day). On the second day, since the temperature of the work environment decreased, the fixing work of the side heat insulating plates could be completed in 1/3 of the conventional work method.

本発明は上記の例に限らず、各請求項に記載された技術的思想の範疇であれば、適宜実施の形態を変更しても良いことは言うまでもない。   The present invention is not limited to the above example, and it goes without saying that the embodiments may be changed as appropriate within the scope of the technical idea described in each claim.

例えば下部ガイドレール１２の拡幅機構は、図２、図３に示した平行リンク機構を用いたものに限らず、図８に示すようなスプリング１６を用いたものでも良い。この場合、スプリング１６はストッパー１７で縮めておき、下部ガイドレール１２を拡幅する際にストッパー１７を外してスプリング１６を解放して拡幅を行う。   For example, the widening mechanism of the lower guide rail 12 is not limited to the one using the parallel link mechanism shown in FIGS. 2 and 3 but may be one using a spring 16 as shown in FIG. In this case, the spring 16 is contracted by the stopper 17, and when the lower guide rail 12 is widened, the stopper 17 is removed and the spring 16 is released to widen the width.

以上の本発明は、炭化室の熱間補修だけでなく、その他の炉の熱間補修にも有効である。   The present invention described above is effective not only for hot repair of the carbonization chamber but also for hot repair of other furnaces.
