Description

【０００１】
【発明の属する技術分野】
本発明は、高炉炉壁内面に周設される高炉炉壁冷却パネルに関する。
【０００２】
【従来の技術】
高炉操業において、炉内の高温反応から鉄皮を保護するため、ステーブクーラーを使用して冷却している。近年、高炉の羽口からの微粉炭吹き込み量が増えるにつれて、高炉炉壁への熱負荷が増大し、かつ変動するようになり、従来の鋳鉄製ステーブクーラーに代わって銅製ステーブクーラーが一部に採用され始めてきている。
【０００３】
図５は従来の銅製ステーブクーラーのステーブ下部拡大図で、鉄皮１２の内側に金属製のステーブ本体２１を配し、ステーブ本体２１内に設けられた冷却水路２２に冷却水を流して鉄皮１２を冷却する。図５はステーブ本体２１の下部のみを示しているが、上部は下部とほぼ対象になっていて、冷却水は下部の冷却水配管２６から給水口２３を経て流入し、上部の排水口を経で冷却水配管から流出する。
【０００４】
従来の銅製ステーブクーラーの構造として、例えば、特公昭６３−５６２８３号公報には、鍛造または圧延された銅または銅合金からなるステーブ本体にドリル加工により水路を穿ち、水路両端を栓溶接するとともに、冷却水配管をステーブ本体に溶接した構造が記載されている。
【０００５】
また、特開平１１−２９３３１２号公報には、鋳造された銅または銅合金からなるステーブ本体で、鋳造時に中子により水路を造形し、凝固後に複数の開口箇所から中子を破壊除去して水路を形成し、ステーブ本体に冷却水配管を溶接した構造が記載されている。
【０００６】
【発明が解決しようとする課題】
このような従来の銅ステーブ構造においては、
（１）銅母材の重量が重く、コスト高となる。
【０００７】
（２）高度な深孔ドリル加工技術や、鋳造技術および栓溶接技術と厳重な検査が要求される。
【０００８】
（３）水路はステーブ本体の母材により形成されていて伝熱性には優れる反面、万一、材質欠陥や使用中に発生する微細クラックから亀裂が進展すれば、直ちに水路の密封性は失われ、炉内への漏水をひきおこす。
【０００９】
（４）密閉水路形成時に図５に示すように栓２４の溶接を避けることができず、長期間の過酷な条件での信頼性に不安が残る。
【００１０】
（５）図５の例のように、冷却水配管２６はステーブ本体２１に直角に近い角度で溶接されることから、冷却水の流れ方向が急変するため、圧損の上昇や水路端部で冷却水の滞留を招くことが懸念される。
【００１１】
（６）図５の例のように、冷却水配管２６は給排水口２３に配管２６の端部を差込み、ステーブ本体２１の給排水口外縁部に開先をとってレ型隅肉溶接により接合されており、曲げや引張りに対する溶接強度は必ずしも十分とは言えない。このため、ステーブ本体の冷却水配管２６が鉄皮１２を貫通する箇所を密封接合する際に、伸縮管２５を介して行い、鉄皮炉外側にその為のスペースが必要であった、という問題があった。
【００１２】
そこで本発明が解決しようとする課題は、高炉炉壁等の冷却に使用される炉壁冷却装置において、ステーブクーラーに代わり、より軽量安価で製作が容易な高炉炉壁冷却パネルを提供するものである。また、冷媒径路上に溶接箇所がなく、漏水の危険性が極めて低く、冷却水の圧損も低く、滞留もなく、伸縮管を省略できて、冷媒の通る配管の長さを短縮できる高炉炉壁冷却パネルを提供するものである。
【００１３】
【課題を解決するための手段】
本発明の高炉炉壁用冷却パネルは、高炉炉壁内面に周設される炉壁冷却パネルにおいて、上下左右に隣接する高炉炉壁冷却パネルの板の外縁を互いに重なり合うように斜面で構成し、高炉炉壁冷却パネルの前面に縦横のリブを格子状に構成するとともに、背面に縦横のリブを格子状に設け、冷媒を通す銅、銅合金または鋼からなる冷媒配管を給水側から排水側まで１本の管材を曲げて炉内側に溶接箇所を設けることなく配置し、銅または銅合金の板に冷媒配管に合わせて切り抜いた切り抜き部に冷媒配管をはめ込んで、板との接線を溶接し、冷媒配管が板から立ち上がる部分を冷媒配管よりも径の大きい鋼管で２重管としたことを特徴とする。
【００１５】
【発明の実施の形態】
以下に、本発明の高炉炉壁冷却パネルを図面に示す例に基づき説明する。図１は本発明の高炉用炉壁冷却パネルの一例を示す正面図、図２は高炉炉壁冷却パネルを炉壁に取り付けた状態を示す水平断面図、図３は冷媒配管が高炉炉壁冷却パネルから立ち上がる部分の二重管構造を示す断面図、図４は冷媒配管の別実施例を示す断面図である。
【００１６】
図１において、銅または銅合金の板１に冷媒を通す冷媒配管２をはめ込むために、冷媒配管に合わせて切り抜いた切り抜き部を形成し、切り抜き部に冷媒配管２をはめ込んで、冷媒配管２と板１との接線をアーク溶接、ガス溶接、ろう付け等の公知の溶接により接合することで高炉用炉壁冷却パネル（以下「冷却パネル」という。）を形成する。冷媒配管２は銅、銅合金または鋼からなり、１本以上のできるだけ少ない本数でパネル面積をむらなく冷却するために、１本以上の管を鉛直や水平に配置したり、鈎型状や蛇行状に曲げて配置する。
【００１７】
炉内面を形成する冷却パネル前面には、補強のために、横リブ３と縦リブ４を格子形状に配置する。また、冷却パネル背面にも横リブ９と縦リブ１０を格子形状に構成する。あるいはリブ３，４に変えて図４に示すようにスタッド５を配置してもよい。
【００１８】
また、冷却パネルの板の外縁を斜面６で構成して、隣接する冷却パネルの外縁の斜面６と互いに重なる構造とすることにより、外縁を垂直に形成するのに比べて伝熱を促進することができ、冷却効果の低下を防ぐことができる。
【００１９】
冷媒配管２が冷却パネルの板１から立ち上がる部分には、冷媒配管２よりも径の大きい鋼管７を外管にして２重管となし、２重管部の鋼管７にて鉄皮１２とシール部材８にて密封接合する。
【００２０】
格子形状のリブ３，４，９，１０またはスタッド５と冷媒配管２を避けた位置には冷却パネルを鉄皮１２に固定する取付ボルト１１が設けられている。冷却パネルを鉄皮１２にボルトで取付した後、鉄皮１２との隙間にキャスタブル１３を流し込む。
【００２１】
冷却パネル前面の格子形状のリブ３，４で形成される溝部またはスタッド５の間には、高炉稼働前にキャスタブル１４を吹き付け、火入れ当初の高熱負荷に対する緩衝効果を持たせる。この吹き付けたキャスタブル１４は、暫時後に脱落するが、すぐに炉内の溶融物等が付着し、前面を覆う。冷却パネル前面の格子形状のリブ３，４またはスタッド５はこの付着物層を安定保持するためにも配置されることが望ましい。
【００２２】
図４において、冷媒配管２を曲げ加工後にプレスし、冷媒配管２の断面形状を楕円形とした場合を示す。冷媒配管２の断面形状を楕円または長円形とすることで、パネル面積に占める管面積の割合を増やすことができ、冷却効果を高めることができる。なお、図４では冷却パネル前面にスタッド５を配置することによって、キャスタブル１３と冷却パネルとが強固に結合される。
【００２３】
【発明の効果】
本発明による高炉用炉壁冷却パネルにより以下の優れた効果が得られる。
【００２４】
（１）銅または銅合金の板と銅、銅合金または鋼からなる冷媒配管とから構成され、極めて軽量、安価に製作することができる。
【００２５】
（２）冷媒配管は給水側から排水側まで、１本の管材を曲げて使用し、炉内側に溶接箇所を設けることなく構成することができるので、長期間の使用に、十分耐えるものである。
【００２６】
（３）冷媒配管は適切な曲げ半径を選ぶことで断面形状の急激な変化なく曲げ加工できるので、冷却水の圧損の上昇や、滞留部をつくることがない。
【００２７】
（４）ゾンデ用開口や出銑口開口の近傍に冷却パネルを設置する場合にも任意の形状に設計・製作できる。また、冷却盤の鉄皮を流用して冷却パネルを設置する場合にも、既設の開口形状に応じて、設計・製作できる。
【００２８】
（５）管の断面形状を楕円または長円形とすることで、冷却パネル面積に占める管部分の面積の割合を増やすことができ、冷却効果を高めることができる。
【００２９】
（６）冷却パネル前面に縦横のリブを格子状に構成するか、またはスタッドを配置し、高炉稼働前にキャスタブルを吹き付け、火入れ当初の高熱負荷に対する緩衝効果を持たせ、稼働後には、炉内の溶融物等が付着保持し易くできる。
【００３０】
（７）冷却パネルの板の外縁を斜面で構成し、上下左右に隣接する冷却パネルの板の外縁斜面部が互いに重なり合うように周設できるので、冷却パネルの目地部での冷却効果の低下を防ぐことができる。
【００３１】
（８）冷媒配管が冷却パネルの板部から立ち上がる部分に冷媒配管よりも径の大きい鋼管を外管にして２重管となすことで補強効果を高めており、鉄皮貫通部の密封も簡単なものでよく、伸縮管を用いる必要はない。そのため、冷却水配管の鉄皮外側での長さを短縮でき、スペースを小さくできる。
【００３２】
（９）冷却パネル背面にも縦横のリブを格子状に構成して熱変形に対する補強効果を高めることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a blast furnace furnace wall cooling panel provided around an inner surface of a blast furnace furnace wall.
[0002]
[Prior art]
In blast furnace operation, a stave cooler is used to cool the iron skin from high temperature reactions in the furnace. In recent years, as the amount of pulverized coal blown from the tuyere's tuyere increased, the heat load on the blast furnace wall increased and fluctuated, and instead of the conventional cast iron stave cooler, a copper stave cooler became part of it. It has begun to be adopted.
[0003]
FIG. 5 is an enlarged view of the lower portion of a stave of a conventional copper stave cooler. A metal stave body 21 is arranged inside the iron skin 12, and cooling water is supplied to a cooling water passage 22 provided in the stave body 21. 12 is cooled. FIG. 5 shows only the lower part of the stave body 21, but the upper part is almost the same as the lower part, and the cooling water flows from the lower cooling water pipe 26 through the water supply port 23 and passes through the upper drainage port. To flow out of the cooling water pipe.
[0004]
As a structure of a conventional copper stave cooler, for example, in Japanese Patent Publication No. 63-56283, a water channel is drilled in a stave body made of forged or rolled copper or copper alloy, and both ends of the water channel are welded by plugs. A structure in which the cooling water pipe is welded to the stave body is described.
[0005]
Japanese Patent Application Laid-Open No. 11-293312 discloses a water channel formed by casting a stave body made of copper or a copper alloy, forming a water channel with a core at the time of casting, and destroying and removing the core from a plurality of openings after solidification. A structure in which a cooling water pipe is welded to the stave body is described.
[0006]
[Problems to be solved by the invention]
In such a conventional copper stave structure,
(1) The weight of the copper base material is heavy and the cost is high.
[0007]
(2) Sophisticated deep hole drilling technology, casting technology and plug welding technology and strict inspection are required.
[0008]
(3) The water channel is formed by the base material of the stave body and is excellent in heat transfer. However, if a crack develops due to a material defect or a fine crack that occurs during use, the water channel seal is immediately lost. , Causing water leakage into the furnace.
[0009]
(4) When the sealed water channel is formed, welding of the plug 24 cannot be avoided as shown in FIG. 5, and there remains anxiety about reliability under severe conditions for a long period of time.
[0010]
(5) Since the cooling water pipe 26 is welded to the stave body 21 at an angle close to a right angle as in the example of FIG. 5, the flow direction of the cooling water changes abruptly. There is a concern of causing water retention.
[0011]
(6) As in the example of FIG. 5, the cooling water pipe 26 is joined by laminar fillet welding with the end of the pipe 26 inserted into the water supply / drain outlet 23 and a groove at the outer edge of the water supply / drain outlet of the stave body 21. Therefore, the welding strength against bending and tension is not always sufficient. For this reason, when the location where the cooling water pipe 26 of the stave body penetrates through the iron shell 12 is hermetically joined, the expansion pipe 25 is used, and a space for that is required outside the iron furnace. was there.
[0012]
Accordingly, the problem to be solved by the present invention is to provide a blast furnace furnace wall cooling panel that is lighter, cheaper and easier to manufacture in place of a stave cooler in a furnace wall cooling apparatus used for cooling blast furnace furnace walls and the like. is there. Also, there are no welding points on the refrigerant path, the risk of water leakage is extremely low, the cooling water pressure loss is low, there is no stagnation, the expansion and contraction pipes can be omitted, and the length of the piping through which the refrigerant passes can be shortened A cooling panel is provided.
[0013]
[Means for Solving the Problems]
The blast furnace wall cooling panel of the present invention, in the furnace wall cooling panel provided around the inner surface of the blast furnace furnace wall, is configured with slopes so that the outer edges of the plates of the blast furnace wall cooling panel adjacent in the vertical and horizontal directions overlap each other, The vertical and horizontal ribs are configured in a grid pattern on the front of the blast furnace wall cooling panel, and the vertical and horizontal ribs are provided in a grid pattern on the back, and a refrigerant pipe made of copper, copper alloy, or steel that passes the refrigerant from the water supply side to the drainage side. One pipe is bent and arranged without providing a welding point inside the furnace, and a refrigerant pipe is fitted into a cut-out portion cut out in accordance with the refrigerant pipe on a copper or copper alloy plate, and a tangent to the plate is welded. A portion where the refrigerant pipe rises from the plate is a double pipe made of a steel pipe having a diameter larger than that of the refrigerant pipe .
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a blast furnace wall cooling panel according to the present invention will be described based on an example shown in the drawings. FIG. 1 is a front view showing an example of a blast furnace wall cooling panel for a blast furnace according to the present invention, FIG. 2 is a horizontal sectional view showing a state in which the blast furnace wall cooling panel is attached to the furnace wall, and FIG. Sectional drawing which shows the double pipe structure of the part which stands | starts up from a panel, FIG. 4 is sectional drawing which shows another Example of refrigerant | coolant piping.
[0016]
In FIG. 1, in order to fit the refrigerant pipe 2 through which the refrigerant passes through the copper or copper alloy plate 1, a cutout part cut out in accordance with the refrigerant pipe is formed, and the refrigerant pipe 2 is fitted into the cutout part. A furnace wall cooling panel for blast furnace (hereinafter referred to as “cooling panel”) is formed by joining tangents to the plate 1 by known welding such as arc welding, gas welding, brazing, or the like. The refrigerant pipe 2 is made of copper, copper alloy, or steel, and in order to cool the panel area evenly with one or more as few as possible, one or more pipes are arranged vertically or horizontally, or in a bowl shape or meandering Bend into a shape.
[0017]
On the front surface of the cooling panel forming the furnace inner surface, the horizontal ribs 3 and the vertical ribs 4 are arranged in a lattice shape for reinforcement. Further, the horizontal ribs 9 and the vertical ribs 10 are also formed in a lattice shape on the rear surface of the cooling panel. Alternatively, the studs 5 may be arranged as shown in FIG.
[0018]
Further, the outer edge of the cooling panel plate is composed of slopes 6 and overlaps with the slope 6 of the outer edge of the adjacent cooling panel, thereby promoting heat transfer compared to the case where the outer edges are formed vertically. It is possible to prevent the cooling effect from being lowered.
[0019]
At the part where the refrigerant pipe 2 rises from the plate 1 of the cooling panel, a steel pipe 7 having a diameter larger than that of the refrigerant pipe 2 is used as an outer pipe to form a double pipe. The steel pipe 7 is sealed with the steel pipe 7 of the double pipe portion. The member 8 is hermetically sealed.
[0020]
Mounting bolts 11 for fixing the cooling panel to the iron skin 12 are provided at positions avoiding the lattice-shaped ribs 3, 4, 9, 10 or the stud 5 and the refrigerant pipe 2. After the cooling panel is attached to the iron skin 12 with bolts, the castable 13 is poured into the gap with the iron skin 12.
[0021]
A castable 14 is sprayed between the grooves or studs 5 formed by the grid-shaped ribs 3 and 4 on the front surface of the cooling panel before the blast furnace is operated, so as to have a buffering effect against a high heat load at the beginning of firing. The sprayable castable 14 falls off after a while, but immediately the molten material in the furnace adheres and covers the front surface. It is desirable that the lattice-shaped ribs 3 and 4 or the studs 5 on the front surface of the cooling panel are arranged in order to stably hold the deposit layer.
[0022]
In FIG. 4, the refrigerant | coolant piping 2 is pressed after a bending process, and the case where the cross-sectional shape of the refrigerant | coolant piping 2 is made into an ellipse is shown. By making the cross-sectional shape of the refrigerant pipe 2 elliptical or oval, the ratio of the pipe area to the panel area can be increased, and the cooling effect can be enhanced. In FIG. 4, the castable 13 and the cooling panel are firmly coupled by arranging the stud 5 on the front surface of the cooling panel.
[0023]
【The invention's effect】
The following excellent effects can be obtained by the furnace wall cooling panel for a blast furnace according to the present invention.
[0024]
(1) It is composed of a copper or copper alloy plate and a refrigerant pipe made of copper, copper alloy or steel, and can be manufactured at a very light weight and at a low cost.
[0025]
(2) Refrigerant piping can be constructed by bending one pipe material from the water supply side to the drainage side without providing a welding point inside the furnace, so that it can sufficiently withstand long-term use. .
[0026]
(3) Since the refrigerant pipe can be bent without a sudden change in the cross-sectional shape by selecting an appropriate bending radius, there is no increase in cooling water pressure loss and no stagnant portion.
[0027]
(4) Even when a cooling panel is installed in the vicinity of the opening for the sonde or the tap hole, it can be designed and manufactured in an arbitrary shape. In addition, when the cooling panel is installed by diverting the iron skin of the cooling panel, it can be designed and manufactured according to the existing opening shape.
[0028]
(5) By making the cross-sectional shape of a pipe into an ellipse or an oval, the ratio of the area of the pipe part to the cooling panel area can be increased, and the cooling effect can be enhanced.
[0029]
(6) The vertical and horizontal ribs are arranged in a lattice pattern on the front of the cooling panel, or studs are placed, and castable is blown before the blast furnace is operated to provide a buffering effect against the high heat load at the beginning of firing. It is possible to easily adhere and hold the molten material.
[0030]
(7) Since the outer edge of the cooling panel plate is composed of slopes, and the outer edge slopes of the cooling panel plates adjacent to the top, bottom, left, and right can be placed around each other, the cooling effect at the joints of the cooling panel is reduced. Can be prevented.
[0031]
(8) Reinforcement effect is enhanced by using a steel pipe with a diameter larger than that of the refrigerant pipe as the outer pipe at the part where the refrigerant pipe rises from the plate part of the cooling panel. There is no need to use a telescopic tube. Therefore, the length of the cooling water piping outside the iron skin can be shortened, and the space can be reduced.
[0032]
(9) Vertical and horizontal ribs can also be formed in a lattice shape on the back side of the cooling panel to enhance the reinforcing effect against thermal deformation.
