　出銑口は、出銑時以外は粘土状のマッド材により封止されている。出銑する際には、専用の開孔機を用いて外部からマッド材を穿孔し、出銑口を開いて溶銑を流出させている。このような出銑作業は２～３時間毎に行われる。 In the blast furnace for iron making, a hot metal outlet is formed on the wall surface of the furnace body of the hot water reservoir, and the hot metal flows out from the hot metal outlet and is received by a scissor and taken out.
The spout is sealed with clay-like mud material except during spout. At the time of brewing, mud material is drilled from the outside using a dedicated opening machine, and the throat is opened to allow the molten iron to flow out. Such tapping work is performed every two to three hours.
　このような出銑を行うために、例えば特許文献１に示す出銑口装置が利用される。特許文献１を含む従来の出銑口装置は、図７のような構成を有する。
　図７において、高炉の炉体９０は、鉄皮９１の内側に冷却用のステーブ９２を配列し、その炉内側に保護用の耐熱レンガ９３を張って構成される。鉄皮９１とステーブ９２ないし耐熱レンガ９３の隙間には、スタンプ材あるいはキャスタブル等の不定形耐火材９４が充填される。 In order to perform such an output, for example, an output port device shown in Patent Document 1 is used. The conventional tap opening device including Patent Document 1 has a configuration as shown in FIG.
In FIG. 7, a furnace body 90 of a blast furnace is configured by arranging a stave 92 for cooling inside an iron skin 91 and extending a heat-resistant brick 93 for protection inside the furnace. A gap between the iron shell 91 and the stave 92 or the heat-resistant brick 93 is filled with an irregular refractory material 94 such as a stamp material or a castable material.
　高炉の出銑口部分９５には、鉄皮９１を貫通する筒状のハウジング９６が設置される。ハウジング９６の先端はステーブ９２の開口を挿通して耐熱レンガ９３の表面に対向するように配置される。ハウジング９６の内部には鉄皮９１と耐熱レンガ９３との間に充填されたものと同様な不定形耐火材９４が充填され、この不定形耐火材９４および耐熱レンガ９３を貫通して炉内に至る出銑用の通路９７が形成されている。 A cylindrical housing 96 penetrating the iron shell 91 is installed at the outlet portion 95 of the blast furnace. The tip of the housing 96 is disposed so as to face the surface of the heat-resistant brick 93 through the opening of the stave 92. The housing 96 is filled with an irregular refractory material 94 similar to that filled between the iron shell 91 and the heat-resistant brick 93, and penetrates the amorphous refractory material 94 and the heat-resistant brick 93 into the furnace. A lead-out passage 97 is formed.

　前述した特許文献１では、出銑口部分のレンガ目地からの炉内ガスリークの問題が指摘されている。
　図８において、出銑口周辺の耐熱レンガ９３の目地隙間が緩む等により、この隙間を通じて炉内ガスＧ１が耐熱レンガ９３の外側に漏れ出すことがある。漏れ出したガスＧ２は、耐熱レンガ９３の表面に沿って出銑口部分９５に達し、さらに出銑用の通路９７内に入り込むことがある。
　このようにして通路９７内に漏れ出したガスＧ３は、出銑のため通路９７を通されている溶銑を吹き飛ばし、流れを乱す等の好ましくない挙動を示す。その結果、出銑作業に支障をきたし、出銑作業を都度中断させなくてはならないことがある。そして、出銑作業が連続して行えないと、必要量の溶銑を出銑するために、出銑作業の回数を増やさなければならず、出銑口の開閉を無駄に繰り返す必要が生じる可能性がある。 In the above-mentioned Patent Document 1, the problem of in-furnace gas leakage from the brick joint at the taphole is pointed out.
In FIG. 8, the gas in the furnace G <b> 1 may leak to the outside of the heat-resistant brick 93 through the gap due to loosening of the joint gap of the heat-resistant brick 93 around the taphole. The leaked gas G <b> 2 reaches the tap outlet portion 95 along the surface of the heat-resistant brick 93 and may further enter the tap-out passage 97.
The gas G3 leaking into the passage 97 in this manner exhibits an undesirable behavior such as blowing away the hot metal passing through the passage 97 for spilling and disturbing the flow. As a result, the output work may be hindered, and the output work may need to be interrupted each time. If the taping operation cannot be performed continuously, the number of taping operations must be increased in order to output the required amount of hot metal, and it may be necessary to repeatedly open and close the tap port. There is.
　このような問題に対し、特許文献１では、耐熱レンガの積み方を工夫することにより、目地が不連続となるように配置し、ガスリークの抑制を図っている。
　しかし、図８に示すように、出銑口部分９５へのガスリークは、近傍の耐熱レンガ９３の目地だけから生じるものではなく、例えば出銑口部分９５から離れた部位のレンガ目地から漏れ出した炉内ガスが、ステーブ９２の炉内側面に沿って流れ、出銑口部分９５に達することもある。また、漏れ出したガスＧ４がステーブ９２の目地に生じた隙間から鉄皮９１側に達し、鉄皮９１の内側に沿って流れ、出銑口部分９５に達することもある。
　このように、前述した特許文献１で提案されている対策では、出銑時のガスリークの抑制が十分でなく、ガスリークによる出銑障害を十分に解決できないという問題がある。 In order to deal with such a problem, Patent Document 1 tries to suppress gas leak by arranging the heat-resistant bricks so that the joints are discontinuous.
However, as shown in FIG. 8, the gas leak to the taphole portion 95 does not occur only from the joints of the nearby heat-resistant bricks 93, for example, leaks from the brick joints at a site away from the tapport portion 95. The in-furnace gas may flow along the inner surface of the stave 92 and may reach the outlet portion 95. Further, the leaked gas G4 may reach the iron skin 91 side from the gap formed at the joint of the stave 92, flow along the inner side of the iron skin 91, and reach the outlet portion 95.
As described above, the countermeasure proposed in Patent Document 1 described above has a problem in that the gas leak at the time of output is not sufficiently suppressed, and the output failure due to the gas leak cannot be sufficiently solved.
　本発明の目的は、出銑時のガスリークを十分に抑制できる出銑口装置を提供することにある。 An object of the present invention is to provide a tap outlet device that can sufficiently suppress gas leak at the time of tapping.
　本発明の出銑口装置は、鉄皮と、前記鉄皮の内側に沿って張られた耐熱レンガと、前記鉄皮を貫通しかつ前記耐熱レンガに対向して配置された筒状のハウジングと、前記ハウジングの前記耐熱レンガ側端部に設置された環状または筒状のシール体とを有し、前記シール体は、前記ハウジングと前記シール体との間を全周にわたって気密シールするハウジング側シールと、前記耐熱レンガと前記シール体との間を全周にわたって気密シールするレンガ側シールとを有することを特徴とする。 The tap door apparatus of the present invention includes an iron skin, a heat-resistant brick stretched along the inner side of the iron skin, and a cylindrical housing disposed through the iron skin and facing the heat-resistant brick. An annular or cylindrical seal body installed at the end of the heat-resistant brick side of the housing, and the seal body hermetically seals between the housing and the seal body over the entire circumference And a brick-side seal that hermetically seals between the heat-resistant brick and the seal body over the entire circumference.
　このような本発明では、ハウジング側シールによりハウジングとシール体との間が全周にわたって気密シールされ、レンガ側シールにより耐熱レンガとシール体との間が全周にわたって気密シールされる。これにより、ハウジング側シールからレンガ側シールに至る環状または筒状のシール体が、ハウジングの端縁と耐熱レンガの表面との間の空間を包囲し、周囲に対して気密シールすることができる。
　このようなシール体により、ハウジング近傍のレンガ目地から漏れ出した炉内ガスや、ステーブ内側あるいは鉄皮内側に沿って伝わってくる炉内ガスは、シール体の内部ないしハウジング内部に侵入することが防止される。 In such this invention, between the housing and the sealing body is hermetically sealed by the housing side seal, and between the heat-resistant brick and the sealing body is hermetically sealed by the brick side seal. Thereby, the cyclic | annular or cylindrical sealing body from a housing side seal to a brick side seal can surround the space between the edge of a housing and the surface of a heat-resistant brick, and can carry out an airtight seal with respect to the circumference | surroundings.
With such a seal body, the furnace gas leaked from the brick joints near the housing and the furnace gas transmitted along the stave or iron core can enter the seal body or the housing. Is prevented.
　従って、出銑用の通路となるべき開口を、耐熱レンガの表面のうちシール体で包囲される領域、つまりレンガ側シールで囲われた領域に形成することで、この開口からシール体で包囲された空間を通りハウジング内部に至る出銑用の通路を確保することができる。
　この通路は、シール体により周囲に対して気密シールされ、炉内ガスの侵入を防止されているから、出銑時においてもガスリークを抑制することができ、ガスリークによる出銑障害を解消することができる。 Therefore, by forming the opening that should be the passage for brewing in the area surrounded by the seal body on the surface of the heat-resistant brick, that is, the area surrounded by the brick side seal, the opening is surrounded by the seal body. It is possible to secure an exit passage through the open space to the inside of the housing.
Since this passage is hermetically sealed with respect to the surroundings by a sealing body and prevents intrusion of the gas in the furnace, gas leakage can be suppressed even at the time of extraction, and the output failure due to gas leakage can be eliminated. it can.
　本発明において、前記シール体は、前記ハウジングの外周面または内周面に沿って前記ハウジングの軸方向に変位可能に支持され、かつ付勢機構により前記耐熱レンガに向けて付勢されていることが望ましい。
　このような付勢機構としては、ガイドロッドに複数の皿ばねを挿通した構造、ガイドロッドにコイルばねを挿通した構造、ガイドロッドと並列に圧縮ばねを配置した構造が適宜利用できる。さらに、ハウジングを変位可能に支持する構成としては、シール体自体をハウジングの内周面あるいは外周面に対して摺動させる構造としてもよく、このような構造とする場合、付勢機構はガイドロッド等を用いずに、単に圧縮ばねでシール体を付勢する構造などとしてもよい。 In the present invention, the seal body is supported so as to be displaceable in the axial direction of the housing along the outer peripheral surface or inner peripheral surface of the housing, and is biased toward the heat-resistant brick by a biasing mechanism. Is desirable.
As such an urging mechanism, a structure in which a plurality of disc springs are inserted into the guide rod, a structure in which a coil spring is inserted into the guide rod, and a structure in which a compression spring is arranged in parallel with the guide rod can be used as appropriate. Furthermore, as a structure for supporting the housing so as to be displaceable, the seal body itself may be slid with respect to the inner peripheral surface or the outer peripheral surface of the housing. In such a structure, the urging mechanism is a guide rod. It is good also as a structure etc. which energize a sealing body only with a compression spring, without using etc.
　このような本発明では、変位可能なシール体を耐熱レンガに向けて付勢することで、ハウジングと耐熱レンガとの間隔が一定でなくてもこの間隔を塞ぐことができ、さらにシール体を耐熱レンガ表面に押し付けることでレンガ側シールにおける気密シール機能を確実にすることができる。
　なお、ハウジング側シールは、ハウジング内周面の寸法形状に応じて設計することで、気密シールに必要なハウジング内周面に対する圧接性能を確保すればよい。 In the present invention, by energizing the displaceable sealing body toward the heat-resistant brick, the gap between the housing and the heat-resistant brick can be closed even if the distance between the housing and the heat-resistant brick is not constant. The airtight sealing function in the brick side seal can be ensured by pressing against the brick surface.
In addition, what is necessary is just to ensure the press contact performance with respect to the housing inner peripheral surface required for an airtight seal by designing the housing side seal according to the dimension shape of a housing inner peripheral surface.
　本発明において、前記シール体は、耐熱性の弾性材料で形成された環状または筒状のシール部材と、前記シール部材を支持する環状のシールホルダとを有する構造とすることができる。
　このような本発明では、ひとつのシール部材でハウジング側シールおよびレンガ側シールを形成でき、構造が簡素にできる。また、シールホルダでシール部材を支持するため、シール部材の全体が弾性材料でも所定の設置位置を維持することができる。 In the present invention, the seal body may have a structure having an annular or cylindrical seal member made of a heat-resistant elastic material and an annular seal holder that supports the seal member.
In the present invention, the housing-side seal and the brick-side seal can be formed with one seal member, and the structure can be simplified. Further, since the seal member is supported by the seal holder, the predetermined installation position can be maintained even if the entire seal member is an elastic material.
　本発明において、前記シール体は、環状または筒状のシールホルダと、前記シールホルダの表面を被覆する耐熱性の弾性材料で形成されたシール部材とを有する構造とすることができる。
　このような本発明では、ひとつのシール部材でハウジング側シールおよびレンガ側シールを形成できるとともに、弾性材料の被覆の内側のシールホルダには剛性を確保することができ、所定の位置に設置して同位置を維持することができる。さらに、シール部材およびシールホルダをひとつのシール体として扱うことができ、構造が簡素にでき、製造あるいは設置に先立つ運搬等も効率的に行うことができる。 In the present invention, the seal body may have a structure having an annular or cylindrical seal holder and a seal member formed of a heat-resistant elastic material that covers the surface of the seal holder.
In the present invention, the housing-side seal and the brick-side seal can be formed with a single seal member, and the seal holder inside the coating of the elastic material can ensure rigidity, and can be installed at a predetermined position. The same position can be maintained. Furthermore, the seal member and the seal holder can be handled as a single seal body, the structure can be simplified, and transportation prior to manufacture or installation can be performed efficiently.
　本発明において、前記シール体は、環状または筒状のシールホルダと、前記シールホルダに設置されて前記ハウジングに圧接されるハウジング側シール部材と、前記シールホルダに設置されて前記耐熱レンガに圧接されるレンガ側シール部材とを有する構造としてもよい。
　このような本発明では、ハウジング側シール部材およびレンガ側シール部材を個別に設置できるため、ハウジングと耐熱レンガとの距離が大きい場合、あるいは形状が特殊な場合などにも適切に対応することができる。 In the present invention, the seal body includes an annular or cylindrical seal holder, a housing-side seal member that is installed on the seal holder and pressed against the housing, and is installed on the seal holder and pressed against the heat-resistant brick. It is good also as a structure which has a brick side sealing member.
In the present invention, since the housing-side sealing member and the brick-side sealing member can be individually installed, it is possible to appropriately cope with a case where the distance between the housing and the heat-resistant brick is large or the shape is special. .
　本発明において、前記ハウジングの周囲にはステーブが設置され、前記ステーブは前記ハウジングを挿通可能な貫通孔を有し、この貫通孔の周囲には、環状に連続しかつ前記鉄皮に対して気密シールされる鉄皮側シールと、環状に連続しかつ前記ハウジングの外周面に対して気密シールされるハウジング外側シールとが形成されていることが望ましい。
　このような本発明では、鉄皮側シールおよびハウジング外側シールにより、鉄皮に沿って流通する炉内ガスを遮断することができ、出銑時のガスリークの抑制をさらに強化することができる。この際、ハウジングの周囲のステーブがハウジングの全周にわたって連続しているため、鉄皮側シールおよびハウジング外側シールも環状に連続して形成することができ、気密シールを確実なものとすることができる。 In the present invention, a stave is installed around the housing, and the stave has a through-hole through which the housing can be inserted. The periphery of the through-hole is continuous in an annular shape and airtight against the iron skin. It is desirable that an iron skin side seal to be sealed and a housing outer seal which is continuous in an annular shape and hermetically sealed with respect to the outer peripheral surface of the housing are formed.
In the present invention, the gas inside the furnace flowing along the iron skin can be shut off by the iron skin side seal and the housing outer seal, and the suppression of gas leakage at the time of tapping can be further strengthened. At this time, since the stave around the housing is continuous over the entire circumference of the housing, the iron side seal and the housing outer seal can be continuously formed in an annular shape, and the airtight seal can be ensured. it can.

　図１において、高炉の炉体１０は、鉄皮１１の内側に冷却用のステーブ１２を配列し、その炉内側に保護用の耐熱レンガ１３を張って構成される。鉄皮１１とステーブ１２ないし耐熱レンガ１３の隙間には、スタンプ材あるいはキャスタブル等の不定形耐火材１４が充填される。
　高炉の出銑口部分１５には、鉄皮１１を貫通する筒状のハウジング１６が設置される。ハウジング１６の先端はステーブ１２の開口を挿通して耐熱レンガ１３の表面に対向するように配置される。ハウジング１６の内部を通して炉内に至る出銑用の通路１７が形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
In FIG. 1, a furnace body 10 of a blast furnace is configured by arranging a stave 12 for cooling inside an iron skin 11 and stretching a heat-resistant brick 13 for protection inside the furnace. A gap between the iron skin 11 and the stave 12 or the heat-resistant brick 13 is filled with an irregular refractory material 14 such as a stamp material or a castable material.
A cylindrical housing 16 that penetrates the iron skin 11 is installed at the tap outlet portion 15 of the blast furnace. The front end of the housing 16 is disposed so as to face the surface of the heat-resistant brick 13 through the opening of the stave 12. An output passage 17 is formed through the interior of the housing 16 to the furnace.
　ハウジング１６の内部には、鉄皮１１と耐熱レンガ１３との間に充填されたものと同様な不定形耐火材１４が充填されている。
　通路１７は、ハウジング１６内の不定形耐火材１４を貫通し、さらに耐熱レンガ１３をその表面（鉄皮１１側の表面）から炉内側（図中左側）へと延びている。
　通路１７内には、通常は封止用のマッド材が充填されており、出銑時にのみマッド材が除去されて管状の通路となり、炉内の溶銑が自身のヘッド圧および炉内の圧力により炉外（図中右側）へと送り出される。 The housing 16 is filled with an amorphous refractory material 14 similar to that filled between the iron shell 11 and the heat-resistant brick 13.
The passage 17 penetrates the amorphous refractory material 14 in the housing 16, and further extends the heat-resistant brick 13 from the surface (surface on the iron skin 11 side) to the inside of the furnace (left side in the figure).
The passage 17 is usually filled with a sealing mud material, and the mud material is removed only during the extraction to form a tubular passage. The hot metal in the furnace is caused by its own head pressure and pressure in the furnace. It is sent out of the furnace (right side in the figure).
　ハウジング１６は鋼製の筒状部材であり、鉄皮１１の開口を貫通する部位において鉄皮１１に対して固定されている。
　図２にも示すように、ハウジング１６の耐熱レンガ１３側端部内には、同端部の開口縁に沿って環状のシール体２０が配置されている。
　シール体２０は、シールホルダ２１で支持されたシール部材２２を有する。 The housing 16 is a steel tubular member, and is fixed to the iron skin 11 at a portion penetrating the opening of the iron skin 11.
As shown in FIG. 2, an annular seal body 20 is disposed in the end portion of the housing 16 on the heat-resistant brick 13 side along the opening edge of the end portion.
The seal body 20 has a seal member 22 supported by a seal holder 21.
　シールホルダ２１は、断面直角三角形状の鋼材を環状に形成したものであり、断面形状における斜辺部分にあたる傾斜面がハウジング１６端縁と耐熱レンガ１３表面との隙間に向けて配置されている。
　シールホルダ２１には周方向に所定間隔でガイドロッド２３が固定されている。ハウジング１６の内周面にはステー２４が溶接等で固定されており、各ガイドロッド２３はそれぞれ対応するステー２４に挿通されて軸方向に進退可能に支持されている。 The seal holder 21 is formed by annularly forming a steel material having a right-angled triangular cross section, and an inclined surface corresponding to a hypotenuse in the cross-sectional shape is arranged toward a gap between the edge of the housing 16 and the surface of the heat-resistant brick 13.
Guide rods 23 are fixed to the seal holder 21 at predetermined intervals in the circumferential direction. A stay 24 is fixed to the inner peripheral surface of the housing 16 by welding or the like, and each guide rod 23 is inserted into the corresponding stay 24 and supported so as to be able to advance and retreat in the axial direction.
　シールホルダ２１とステー２４との間には、ガイドロッド２３に挿通された複数の皿ばね２５が設置され、この皿ばね２５によりシールホルダ２１はステー２４から離れる方向へ付勢され、つまり耐熱レンガ１３の表面に向けて付勢されている。
　なお、ガイドロッド２３には、ステー２４の耐熱レンガ１３とは反対側にナット２６が螺合されており、このナット２６により外れ止めがなされるとともに、前述した付勢力を発生させるための初期圧縮が行われている。
　これらのガイドロッド２３および皿ばね２５により、付勢機構が構成されている。 A plurality of disc springs 25 inserted through the guide rods 23 are installed between the seal holder 21 and the stay 24, and the disc holder 25 biases the seal holder 21 away from the stay 24, that is, a heat-resistant brick. 13 is biased toward the surface.
Note that a nut 26 is screwed onto the guide rod 23 on the opposite side of the stay 24 from the heat-resistant brick 13, and the nut 26 is prevented from coming off, and the initial compression for generating the biasing force described above is performed. Has been done.
The guide rod 23 and the disc spring 25 constitute an urging mechanism.
　シール部材２２は、断面円形の耐熱性エラストマを環状に形成したものであり、シールホルダ２１の断面形状における斜辺部分に相当する傾斜面に当接されている。
　前述のように、シールホルダ２１は耐熱レンガ１３に向けて付勢されており、シールホルダ２１が耐熱レンガ１３に向けて変位することで、その傾斜面により耐熱レンガ１３表面に向けて押し付けられるとともに、ハウジング１６の端部開口の内周面にも押し付けられる。言い換えれば、シール部材２２は、ハウジング１６端縁と耐熱レンガ１３表面との隙間に向けて押し付けられる。
　なお、シール部材２２の外径は、ハウジング１６内周径よりも幾分大きく形成され、ハウジング１６内にシール部材２２を収容した際にはシール部材２２の外周がハウジング１６の内周面に圧接され、気密シールとして十分な圧接性能が確保されている。 The seal member 22 is formed by annularly forming a heat-resistant elastomer having a circular cross section, and is in contact with an inclined surface corresponding to the oblique side portion in the cross-sectional shape of the seal holder 21.
As described above, the seal holder 21 is urged toward the heat-resistant brick 13, and the seal holder 21 is displaced toward the heat-resistant brick 13 so that the inclined surface is pressed toward the surface of the heat-resistant brick 13. The inner surface of the end opening of the housing 16 is also pressed. In other words, the seal member 22 is pressed toward the gap between the edge of the housing 16 and the surface of the heat-resistant brick 13.
The outer diameter of the seal member 22 is formed somewhat larger than the inner peripheral diameter of the housing 16, and when the seal member 22 is accommodated in the housing 16, the outer periphery of the seal member 22 is pressed against the inner peripheral surface of the housing 16. Therefore, sufficient pressure contact performance as an airtight seal is ensured.
　本実施形態においては、シールホルダ２１によってシール部材２２がハウジング１６の端部開口の内周面に全周にわたり押し付けられることで、ハウジング１６の内周とシール部材２２との間に気密シール性能を有するハウジング側シール２２１が形成される。
　また、シールホルダ２１によってシール部材２２が耐熱レンガ１３の表面にシール部材２２の全周にわたって押し付けられることで、耐熱レンガ１３の表面とシール部材２２との間に気密シール性能を有するレンガ側シール２２２が形成される。 In the present embodiment, the seal member 22 is pressed against the inner peripheral surface of the end opening of the housing 16 over the entire circumference by the seal holder 21, so that an airtight sealing performance is provided between the inner circumference of the housing 16 and the seal member 22. A housing side seal 221 is formed.
Further, the sealing member 22 is pressed against the surface of the heat-resistant brick 13 by the seal holder 21 over the entire circumference of the sealing member 22, so that the brick-side seal 222 having an airtight sealing performance between the surface of the heat-resistant brick 13 and the sealing member 22. Is formed.
　このようなシール部材２２およびシールホルダ２１を有するシール体２０により、ハウジング１６端縁と耐熱レンガ１３表面との隙間が気密状態で封止される。
　従って、耐熱レンガ１３の目地から漏れ出した炉内ガスＧ１が、耐熱レンガ１３の表面に沿って流れるガスＧ２、あるいはステーブ１２の目地から漏れ出して鉄皮１１の内側に沿って流れるガスＧ４となり、ハウジング１６近傍に流れてきたとしても、ハウジング１６端縁と耐熱レンガ１３表面との隙間はシール体２０によって封止され、リークガスがハウジング１６内ないし出銑用の通路１７内に吹き込むことを防止することができる。 By the sealing body 20 having such a sealing member 22 and the seal holder 21, the gap between the edge of the housing 16 and the surface of the heat-resistant brick 13 is sealed in an airtight state.
Therefore, the in-furnace gas G1 leaking from the joint of the heat-resistant brick 13 becomes the gas G2 flowing along the surface of the heat-resistant brick 13 or the gas G4 leaking from the joint of the stave 12 and flowing along the inside of the iron skin 11. Even if it flows in the vicinity of the housing 16, the gap between the edge of the housing 16 and the surface of the heat-resistant brick 13 is sealed by the sealing body 20, and leak gas is prevented from being blown into the housing 16 or the outlet passage 17. can do.
　さらに、本実施形態では、出銑口部分１５を一枚でカバーするステーブ１２が用いられている。
　ステーブ１２は、図３Ａ及びＢに示すように、鋳鉄または銅合金等で形成された板状の本体１２０を有し、その内部には冷却用配管１２２が形成されているとともに、中央部には出銑用開口１２１が形成されている。
　本体１２０の鉄皮１１側の表面（図２参照）には、出銑用開口１２１に沿って環状に連続した凸条１２３が形成され、その先端面には耐熱性エラストマで形成されたシール部材１２４が装着されている。また、出銑用開口１２１の内側には、凸条１２３が形成された側の開口縁に沿って内向きの凸条１２５が形成され、その先端面には耐熱性エラストマで形成されたシール部材１２６が装着されている。 Furthermore, in this embodiment, the stave 12 which covers the spout part 15 with one sheet is used.
As shown in FIGS. 3A and 3B, the stave 12 has a plate-like main body 120 formed of cast iron, copper alloy, or the like, and a cooling pipe 122 is formed therein, and a central portion thereof is formed. An output opening 121 is formed.
On the surface of the main body 120 on the iron skin 11 side (see FIG. 2), a ridge 123 continuously formed in an annular shape along the opening for opening 121 is formed, and a seal member formed of a heat-resistant elastomer on the tip surface thereof. 124 is attached. In addition, an inwardly protruding ridge 125 is formed on the inner side of the protruding opening 121 along the opening edge on the side where the ridge 123 is formed, and a seal member formed of a heat-resistant elastomer on the tip surface thereof. 126 is attached.
　図２に戻って、出銑口部分１５に設置されたステーブ１２は、シール部材１２４が鉄皮１１の内周面に押し付けられ、シール部材１２６がハウジング１６の外周面に押し付けられる。これらのシール部材１２４，１２６により、鉄皮１１の内側に沿ってハウジング１６に向けて流れるガスＧ４を遮断することができる。
　前述のように、ハウジング１６と耐熱レンガ１３との間は、ハウジング側シール２２１およびレンガ側シール２２２を有するシール体２０により気密シールされているが、これらのシール部材１２４，１２６によって鉄皮１１の内側からのガスＧ４が遮断されることで、通路１７に至るガスリークの防止性能を一層高めることができる。 Returning to FIG. 2, in the stave 12 installed in the spout portion 15, the seal member 124 is pressed against the inner peripheral surface of the iron skin 11, and the seal member 126 is pressed against the outer peripheral surface of the housing 16. By these seal members 124 and 126, the gas G4 flowing toward the housing 16 along the inner side of the iron skin 11 can be blocked.
As described above, the housing 16 and the heat-resistant brick 13 are hermetically sealed by the seal body 20 having the housing-side seal 221 and the brick-side seal 222, but the iron members 11 are sealed by these seal members 124 and 126. By blocking the gas G4 from the inside, the performance of preventing gas leakage reaching the passage 17 can be further enhanced.
　なお、既存の高炉においては、一般に出銑口部分１５に配置されるステーブとして、図４に示すような３分割式のステーブ８１，８２，８３が用いられる。
　このような３分割方式とすることで、ハウジング１６を通すための開口８４を形成することが容易である。
　しかし、このような３分割式のステーブ８１，８２，８３では、開口８４の周縁も分割されるため、全周にわたって連続した気密シールを形成することが難しい。
　これに対し、図３Ａ及びＢのような一枚もののステーブ１２を用いることで、全周にわたって連続したシール部材１２４，１２６を設置することが容易にできる。
　なお、従来の出銑口部分１５用のステーブとしては２分割式もあるが、前述した３分割式と同様な問題があり、図３Ａ及びＢのような一枚もののステーブ１２のほうが望ましい。 In existing blast furnaces, three-part staves 81, 82, and 83 as shown in FIG.
By adopting such a three-division method, it is easy to form the opening 84 through which the housing 16 is passed.
However, in such a three-divided stave 81, 82, 83, since the periphery of the opening 84 is also divided, it is difficult to form a continuous hermetic seal over the entire circumference.
On the other hand, by using a single stave 12 as shown in FIGS. 3A and 3B, it is possible to easily install the sealing members 124 and 126 continuous over the entire circumference.
In addition, although the conventional stave for the spout opening portion 15 has a two-split type, there is a problem similar to the above-described three-split type, and a single stave 12 as shown in FIGS. 3A and 3B is more preferable.
　このような本実施形態によれば、以下のような効果がある。
　本実施形態では、シール体２０により、ハウジング１６と耐熱レンガ１３の表面との間の隙間を封止することができる。シール体２０は、ハウジング側シール２２１によりハウジング１６の内周に対して全周にわたって気密シールすることができ、レンガ側シール２２２により耐熱レンガ１３の表面に対して全周にわたって気密シールすることができる。
　これにより、ハウジング１６の内部および出銑用の通路１７は、シール体２０によって周囲に対して気密シールされ、ハウジング１６近傍のレンガ目地から漏れ出した炉内ガスＧ１、耐熱レンガ１３の表面やステーブ１２あるいは鉄皮１１に沿って伝わってくるガスＧ２，Ｇ４等が通路１７まで侵入することを防止でき、出銑時のガスリークを十分に抑制し、ガスリークによる出銑障害を解消することができる。 According to this embodiment, there are the following effects.
In the present embodiment, the seal body 20 can seal the gap between the housing 16 and the surface of the heat-resistant brick 13. The seal body 20 can be hermetically sealed with respect to the inner periphery of the housing 16 by the housing side seal 221, and can be hermetically sealed with respect to the surface of the heat-resistant brick 13 by the brick side seal 222. .
As a result, the interior of the housing 16 and the output passage 17 are hermetically sealed with respect to the surroundings by the seal body 20, and the furnace gas G 1 leaked from the brick joints near the housing 16, the surface of the heat-resistant brick 13 and the stave. 12 or the gas G2, G4, etc. transmitted along the iron skin 11 can be prevented from entering the passage 17, gas leakage at the time of output can be sufficiently suppressed, and output failure due to gas leak can be eliminated.
　とくに、本実施形態では、ハウジング側シール２２１およびレンガ側シール２２２が、同じシール部材２２に形成されるため、シール部材２２の設置によりハウジング側シール２２１およびレンガ側シール２２２を一括して設置することができ、構造を簡素化することができる。
　シール部材２２は全体が弾性部材であるが、これを支持するシールホルダ２１に十分な剛性を確保することができ、シール部材２２を所定の位置に維持することができる。
　シール部材２２においては、ハウジング側シール２２１およびレンガ側シール２２２からシールホルダ２１までの距離が大きく、当該部分で圧縮されるシール部材２２の弾性材料の厚みが大きくなり、気密シール性能を向上することもできる。 In particular, in this embodiment, since the housing side seal 221 and the brick side seal 222 are formed on the same seal member 22, the housing side seal 221 and the brick side seal 222 are collectively installed by the installation of the seal member 22. And the structure can be simplified.
The seal member 22 is an elastic member as a whole, but sufficient rigidity can be secured for the seal holder 21 that supports the seal member 22, and the seal member 22 can be maintained at a predetermined position.
In the seal member 22, the distance from the housing side seal 221 and the brick side seal 222 to the seal holder 21 is large, and the thickness of the elastic material of the seal member 22 compressed in the portion is increased, thereby improving the hermetic seal performance. You can also.
　シールホルダ２１は、ガイドロッド２３に挿通された皿ばね２５により耐熱レンガ１３に向けて付勢されているため、レンガ側シール２２２を耐熱レンガ１３表面に押し付けることができ、レンガ側シール２２２における気密シールを確実にすることができる。
　なお、シールホルダ２１の付勢機構としては、ガイドロッド２３に挿通された皿ばね２５のほか、ガイドロッドにコイルばねを挿通した構造、ガイドロッドと並列に圧縮ばねを配置した構造を利用してもよい。 Since the seal holder 21 is biased toward the heat-resistant brick 13 by the disc spring 25 inserted through the guide rod 23, the brick-side seal 222 can be pressed against the surface of the heat-resistant brick 13. The seal can be ensured.
As the biasing mechanism of the seal holder 21, a disc spring 25 inserted through the guide rod 23, a structure in which a coil spring is inserted into the guide rod, and a structure in which a compression spring is arranged in parallel with the guide rod are used. Also good.
〔第２実施形態〕
　本実施形態は、前述した第１実施形態と同様な構造を有するが、シール体２０とは異なる構成を有する。従って、共通する構成については第１実施形態と同じ符号を付して説明を省略し、以下には相違するシール体について詳細に説明する。 [Second Embodiment]
The present embodiment has a structure similar to that of the first embodiment described above, but has a configuration different from that of the seal body 20. Therefore, the same reference numerals as those in the first embodiment are assigned to the common configurations and the description thereof is omitted, and different seal bodies will be described in detail below.
　図５において、本実施形態のシール体２０Ａは、環状に形成された鋼製のシールホルダ２１Ａを有し、その表面に耐熱性エラストマで形成されたシール部材２２Ａが被覆されている。
　シール部材２２Ａは、前述した第１実施形態のシール部材２２（図２参照）と同様の位置に配置される。その結果、シール部材２２Ａがハウジング１６の端部開口の内周面に全周にわたり押し付けられることで、ハウジング１６の内周とシール部材２２Ａとの間に気密シール性能を有するハウジング側シール２２１が形成される。また、シール部材２２Ａが耐熱レンガ１３の表面にシール部材２２の全周にわたって押し付けられることで、耐熱レンガ１３の表面とシール部材２２Ａとの間に気密シール性能を有するレンガ側シール２２２が形成される。
　これらのシールホルダ２１Ａおよびシール部材２２Ａにより、ハウジング側シール２２１およびレンガ側シール２２２を有するシール体２０Ａが形成され、ハウジング１６と耐熱レンガ１３の表面との隙間はシール体２０Ａにより封止される。 In FIG. 5, the seal body 20A of the present embodiment has a steel seal holder 21A formed in an annular shape, and the surface thereof is covered with a seal member 22A formed of a heat-resistant elastomer.
The seal member 22A is disposed at the same position as the seal member 22 (see FIG. 2) of the first embodiment described above. As a result, the seal member 22A is pressed against the inner peripheral surface of the end opening of the housing 16 over the entire periphery, thereby forming a housing-side seal 221 having an airtight seal performance between the inner periphery of the housing 16 and the seal member 22A. Is done. Further, the sealing member 22A is pressed against the surface of the heat-resistant brick 13 over the entire circumference of the sealing member 22, so that a brick-side seal 222 having an airtight sealing performance is formed between the surface of the heat-resistant brick 13 and the sealing member 22A. .
A seal body 20A having a housing side seal 221 and a brick side seal 222 is formed by the seal holder 21A and the seal member 22A, and a gap between the housing 16 and the surface of the heat-resistant brick 13 is sealed by the seal body 20A.
　このような本実施形態では、シール体２０Ａによってハウジング１６と耐熱レンガ１３の表面との間の気密シールが確保され、前述した第１実施形態と同様の効果を得ることができる。
　さらに、本実施形態のシール体２０Ａは、シールホルダ２１Ａの表面に耐熱性エラストマで形成されたシール部材２２Ａを被覆して構成されるため、これらを一体に取り扱うことができ、設置スペースを小型化できるとともに、製造工程を簡略化することができる。 In this embodiment, an airtight seal between the housing 16 and the surface of the heat-resistant brick 13 is ensured by the seal body 20A, and the same effect as in the first embodiment described above can be obtained.
Furthermore, since the seal body 20A of the present embodiment is configured by covering the surface of the seal holder 21A with a seal member 22A formed of a heat-resistant elastomer, these can be handled integrally, and the installation space can be reduced in size. In addition, the manufacturing process can be simplified.
〔第３実施形態〕
　本実施形態は、前述した第１実施形態と同様な構造を有するが、シール体２０とは異なる構成を有する。従って、共通する構成については第１実施形態と同じ符号を付して説明を省略し、以下には相違するシール体について詳細に説明する。 [Third Embodiment]
The present embodiment has a structure similar to that of the first embodiment described above, but has a configuration different from that of the seal body 20. Therefore, the same reference numerals as those in the first embodiment are assigned to the common configurations and the description thereof is omitted, and different seal bodies will be described in detail below.
　図６において、本実施形態のシール体２０Ｂは、筒状に形成された断面Ｌ字状の鋼製のシールホルダ２１Ｂを有する。
　シールホルダ２１Ｂは、ハウジング１６の内周面に沿う筒状の部分と耐熱レンガ１３の表面に沿う環状の板材とを溶接して製造することができる。ただし、Ｌ形鋼を環状に曲げて製造してもよい。 In FIG. 6, the seal body 20 </ b> B of the present embodiment has a steel seal holder 21 </ b> B having an L-shaped cross section formed in a cylindrical shape.
The seal holder 21 </ b> B can be manufactured by welding a cylindrical portion along the inner peripheral surface of the housing 16 and an annular plate member along the surface of the heat-resistant brick 13. However, the L-shaped steel may be bent into a ring shape.
　シールホルダ２１Ｂのハウジング１６と対向する外周面にはハウジング側シール部材２２１Ｂが設置されている。また、シールホルダ２１Ｂの耐熱レンガ１３の表面に対向する面にはレンガ側シール部材２２２Ｂが設置されている。
　これらのハウジング側シール部材２２１Ｂおよびレンガ側シール部材２２２Ｂは、各々全周にわたって連続した耐熱性エラストマで形成されている。
　ハウジング側シール部材２２１Ｂは、ハウジング１６に押し付けられることでハウジング側シールを形成し、レンガ側シール部材２２２Ｂは耐熱レンガ１３の表面に押し付けられることでレンガ側シールを形成する。
　これらのシールホルダ２１Ｂ、ハウジング側シール部材２２１Ｂおよびレンガ側シール部材２２２Ｂにより、シール体２０Ｂが形成されている。 A housing-side seal member 221B is installed on the outer peripheral surface of the seal holder 21B facing the housing 16. Further, a brick-side seal member 222B is installed on the surface of the seal holder 21B that faces the surface of the heat-resistant brick 13.
Each of the housing side seal member 221B and the brick side seal member 222B is formed of a heat resistant elastomer that is continuous over the entire circumference.
The housing-side seal member 221B forms a housing-side seal by being pressed against the housing 16, and the brick-side seal member 222B is pressed against the surface of the heat-resistant brick 13 to form a brick-side seal.
A seal body 20B is formed by the seal holder 21B, the housing-side seal member 221B, and the brick-side seal member 222B.
　このような本実施形態では、シール体２０Ｂによってハウジング１６と耐熱レンガ１３との間の気密シールが確保され、前述した第１実施形態と同様の効果を得ることができる。
　さらに、本実施形態のシール体２０Ｂは、シールホルダ２１Ｂにハウジング側シール部材２２１Ｂおよびレンガ側シール部材２２２Ｂを別々に設置するため、各々の距離が離れていたり、各々の向きが異なっていたりしても、柔軟に対応が可能であり、設計自由度を高めることができる。
　また、ハウジング側シール部材２２１Ｂおよびレンガ側シール部材２２２Ｂは、各々の表面を幅広い面でハウジング１６あるいは耐熱レンガ１３の表面に圧接させることができ、気密シール性能を一層高めることができる。 In this embodiment, an airtight seal between the housing 16 and the heat-resistant brick 13 is secured by the seal body 20B, and the same effect as that of the first embodiment described above can be obtained.
Furthermore, since the seal body 20B of this embodiment separately installs the housing-side seal member 221B and the brick-side seal member 222B in the seal holder 21B, the distances between the seal bodies 20B are different or the directions are different. However, it is possible to respond flexibly, and the degree of design freedom can be increased.
Further, the housing-side seal member 221B and the brick-side seal member 222B can press the surfaces of the housing-side seal member 221B and the brick-side seal member 222B on the surface of the housing 16 or the heat-resistant brick 13 in a wide range, and can further improve the hermetic seal performance.
