Description
【０００１】[0001]
従来、抽出エキストラクタを備えたウォーキングビーム式加熱炉においては、 炉抽出部開口の下方に、エキストラクタのラム進退用開口が設けてあるため、こ の開口から外気が炉内に侵入したり、炉気が炉外に噴出し、熱効率が低下すると いう欠点を有していた。 Conventionally, in a walking beam type heating furnace equipped with an extraction extractor, the ram advancing / retreating opening of the extractor is provided below the opening of the furnace extraction part, so outside air may enter the furnace through this opening. It had a drawback that the furnace air spouted out of the furnace and the thermal efficiency decreased.
【０００２】[0002]
前記欠点を除却するために、特公昭５８−７９１０号公報で外気が炉内に侵入 するのを防止する侵入空気防止装置が提案されている。 すなわち、エキストラクタラムが進退する開口の前端部に、多数の噴出ノズル を配設し、この噴出ノズルから空気等の気体を、エキストラクタラムの挿入ライ ンに集束するように噴出させることにより、外気の炉内侵入を防止するものであ る。 In order to eliminate the above-mentioned drawbacks, Japanese Patent Publication No. 58-7910 proposes an intruding air preventive device for preventing outside air from entering the furnace. That is, a large number of ejection nozzles are provided at the front end of the opening through which the extractor ram advances and retracts, and a gas such as air is ejected from this ejection nozzle so as to focus on the insertion line of the extractor ram. It prevents outside air from entering the furnace.
【０００３】[0003]
しかしながら、前記提案では、噴出ノズルは開口の前端部にのみ配設されてい るためシール性が悪い。また、炉抽出部開口には扉が設けられているが、扉開放 時に炉内ガスが炉外に噴出して熱効率が悪いという課題を有していた。 本考案は、エキストラクタラム進退用開口を、排ガスカーテンによりシールす ることにより、前記課題を解決するウォーキングビーム式加熱炉の抽出部開口用 シール装置を提供することを目的とする。 However, in the above-mentioned proposal, the ejection nozzle is disposed only at the front end portion of the opening, so that the sealing property is poor. Further, although a door is provided at the opening of the furnace extraction part, there was a problem that the gas inside the furnace spouted out of the furnace when the door was opened and the thermal efficiency was poor. An object of the present invention is to provide a sealing device for an opening of an extraction part of a walking beam type heating furnace which solves the above problems by sealing the opening for advancing and retracting the extractor ram with an exhaust gas curtain.
【０００４】[0004]
本考案は、前記目的を達成するために、抽出エキストラクタを備えたウォーキ ングビーム式加熱炉において、炉抽出部開口下方に設けたエキストラクタラム進 退用開口の対向内壁部に、排ガスを噴出する多数の噴出ノズルを配設し、あるい は、さらに炉抽出部開口の天井部にも多数の噴出ノズルを配設したものである。 According to the present invention, in order to achieve the above-mentioned object, in a walking beam type heating furnace equipped with an extraction extractor, exhaust gas is ejected to the inner wall portion of the extractor ram advancing / retreating opening provided below the opening of the furnace extracting section. A large number of jet nozzles are arranged, or a large number of jet nozzles are also arranged on the ceiling of the furnace extraction section opening.
【０００５】[0005]
つぎに、本考案の一実施例を図面にしたがって説明する。 図１，図２は、ウォーキングビーム式加熱炉１の抽出部を示し、抽出部開口２ の天井部には、多数の下方に開口する噴出ノズル４を有するノズルボックス３が 設けられている。 また、抽出部開口２の下方の炉壁には炉内に突出した突壁部５が設けられてお り、この突壁部５にエキストラクタ（ラム）９が進退する複数の切欠き部からな る開口６が形成されている。そして、この開口６の対向する内壁部には、前記開 口６に向かって排ガスを噴出する噴出ノズル７が設けられている。 Next, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show an extraction part of a walking beam type heating furnace 1, and a nozzle box 3 having a large number of downward jet nozzles 4 is provided on the ceiling of the extraction part opening 2. Further, a projecting wall portion 5 that projects into the furnace is provided on the furnace wall below the extraction unit opening 2, and a plurality of notches through which the extractor (ram) 9 moves forward and backward are provided on the projecting wall portion 5. An opening 6 is formed. A jet nozzle 7 for jetting the exhaust gas toward the opening 6 is provided on the inner wall portion facing the opening 6.
【０００６】 なお、前記ノズルボックス３および噴出ノズル７は各々排ガスヘッダ８に連通 している。この排ガスヘッダ８に供給される排ガスは、当該加熱炉の排ガスであ っても、他の設備からの排ガスであってもよい。また、その温度は抽出部温度と ほぼ同じであることが好ましい。その他、１１は抽出テーブルである。The nozzle box 3 and the ejection nozzle 7 are in communication with the exhaust gas header 8. The exhaust gas supplied to the exhaust gas header 8 may be exhaust gas from the heating furnace or exhaust gas from other equipment. Further, the temperature is preferably almost the same as the temperature of the extraction section. In addition, 11 is an extraction table.
【０００７】 前記構成からなるため、材料Ｗの抽出のために抽出扉１０を開放しても、抽出 部開口２は噴出ノズル４からの排ガスでエアーカーテンが形成され、また、前記 開口６も噴出ノズル７からの排ガスでエアーカーテンが形成され、炉気が外方に 噴出することあるいは外気が炉内に侵入することが防止される。Because of the above configuration, even if the extraction door 10 is opened to extract the material W, an air curtain is formed in the extraction part opening 2 by the exhaust gas from the ejection nozzle 4, and the opening 6 is also ejected. Exhaust gas from the nozzle 7 forms an air curtain, which prevents the furnace air from being blown out or the outside air from entering the furnace.
【０００８】 なお、前記噴出ノズル４，７からの排ガス噴出は、抽出扉１０の開閉に連動し て開放的にのみ行ない、閉鎖時には停止するようにしてもよい。The exhaust gas jet from the jet nozzles 4 and 7 may be performed only in an open manner in conjunction with opening and closing of the extraction door 10 and may be stopped when closed.
【０００９】[0009]
以上の説明で明らかなように、本考案によれば、加熱炉のエキストラクタラム の進退用開口は、排ガスカーテンでシールされるので、抽出扉の開放時における 炉気の炉外噴出および外気の炉内侵入を完全に防止でき、熱損失を低減すること ができる。 また、エアーカーテンは排ガスであり、かつ、外気の炉内侵入がないため、炉 内バーナの空燃比が乱れず、炉内Ｏ2制御が行ない易い等の効果を奏する。 なお、排ガスと炉内温度とを同等温度とすれば、熱ロスも軽減することができ る。 さらに、抽出部開口の天井部にも噴出ノズルを設ければ、より一層熱損失の低 減等を図ることができる。As is clear from the above description, according to the present invention, the advancing / retreating opening of the extractor ram of the heating furnace is sealed by the exhaust gas curtain, so that when the extraction door is opened It is possible to completely prevent intrusion into the furnace and reduce heat loss. Further, since the air curtain is exhaust gas and there is no outside air entering the furnace, the air-fuel ratio of the in-furnace burner is not disturbed and the in-furnace O 2 control is easily performed. It should be noted that heat loss can be reduced by making the exhaust gas and the furnace temperature the same. Furthermore, if a jet nozzle is also provided in the ceiling of the opening of the extraction section, the heat loss can be further reduced.
