本考案は、容器底部から容器内の溶融金属にガ
スを吹込みバブリングを行うガス吹込みプラグの
構造に関する。[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a gas blowing plug that blows gas into molten metal in a container from the bottom of the container to effect bubbling.
従来、溶鋼のような溶融金属に、ガス吹込みを

内部にスリツト状のガス通気孔を設けた通気性れ
んがを装着したものがある。
Conventionally, the mechanism for blowing gas into molten metal such as molten steel was to install a porous plug in which the entire plug was made porous for air permeability, and the structure for blowing a relatively large amount of gas was ,
Some are equipped with breathable bricks with slit-shaped gas ventilation holes inside.
これらの通気性れんがを装着したガス吹込み構
造においては、比較的脆弱な耐火物によつてガス
吹込み口が形成されているため、ガス吹込み時の
溶融金属との撹拌によつて、通気口が破損し耐久
性において問題があつた。 In gas injection structures equipped with these permeable bricks, the gas injection ports are made of relatively fragile refractories, so the ventilation is prevented by stirring with the molten metal during gas injection. The mouth was damaged and there was a problem with durability.
また、このガス吹込み構造として、緻密質のれ
んがに鋼製の細管を埋込んで形成された通気性れ
んがを使用することも提案されている。 It has also been proposed to use a permeable brick made by embedding steel tubes in a dense brick as the gas blowing structure.
しかしながら、この鋼製の細管を埋込んだれん

れんがを得ることは極めて困難で、このため、埋
込み鋼管と耐火物の間に溶融金属が侵入し、その
部分での損耗が進み、安定した長寿命のガス吹込
み構造を得ることができないという欠点がある。 However, manufacturing bricks with embedded steel tubes is difficult, and the embedded tubes and the molded refractory become separated during firing, making it extremely difficult to obtain bricks that are completely integrated. Therefore, there is a drawback that molten metal enters between the embedded steel pipe and the refractory, and wear and tear progresses in that part, making it impossible to obtain a stable and long-life gas injection structure.
本考案の目的は、組立が簡単で、且つ、長寿命
の溶融金属へのガス吹込みプラグを提供すること
にある。
It is an object of the present invention to provide a plug for blowing gas into molten metal that is easy to assemble and has a long service life.
本考案のガス吹込みプラグは、溶融金属容器の
内張りに設けられたガス吹込みプラグにおいて、
複数のガス吹込み用細管が上面に開口し、且つガ

とを特徴とする。
The gas blowing plug of the present invention is a gas blowing plug provided on the lining of a molten metal container.
It is characterized in that a plurality of thin tubes for blowing gas are embedded in a monolithic refractory with an opening on the upper surface and converging on the gas supply pipe side to form a connecting part with the gas supply pipe.
本考案のガス吹込みプラグは、炉外においてガ
ス吹込み用細管を配置し、そこに不定形耐火物を
流し込むだけで簡単に形成できる。
The gas injection plug of the present invention can be easily formed by simply arranging a gas injection thin tube outside the furnace and pouring the monolithic refractory into it.
また、各ガス吹込み用細管の噴出端は不定形耐
火物の上面から突出した状態で配置しておくのが
不定形耐火物を流し込むに当たつて、閉塞の問題
を生じることがなく成形できる。 In addition, by arranging the ejection end of each gas injection capillary so as to protrude from the top surface of the monolithic refractory, it is possible to form the monolithic refractory without causing blockage problems when pouring the monolithic refractory. .
以下、添付図に示す実施例に基づいて本考案を

The present invention will be described below based on embodiments shown in the accompanying drawings.

時の細管の閉塞防止の点から好ましい。In these figures, 1 is the outer shell of the container, 2 is the lining brick of the container, 3 is the joint made of the lining brick 2 and the monolithic refractory molded body 24, and 4 is the part embedded in the part made of the monolithic refractory material. The installed gas injection capillary tube is shown. The gas injection tube 4 has an inner diameter of 0.1~
2.0mm stainless steel, copper, aluminum, heat-resistant resin, etc. are also possible materials for the pipe, and depending on the mode of gas injection, it is made up of a set 5 of multiple pipes, and can be attached or detached from the container. Depending on the width of the gas inlet of the molded body 24 of the shaped refractory, a plurality of wires are arranged in parallel with wires 6 and bent at a point close to the outer shell 1 side of the molded body 24 to match the length. The ends are inserted into the hole 9 of the socket section 7, and a filler is embedded therein and fixed as the connection section 8. Note that the cross-sectional shape of the thin tube 4 may be other than a perfect circle. Filling materials for the connecting portion 8 include organic binders, inorganic binders, sealants, frits, cermets, and other metals with relatively low melting points, such as solder, tin, lead,
Aluminum etc. are easy to construct. Note that a material with a high melting point may be used, although processing is troublesome. In addition, the ejection end of each gas injection thin tube 4 is connected to a molded body 2 as shown in the figure.
It is preferable for the tube to protrude from the upper surface of the tube 4 from the viewpoint of preventing clogging of the capillary tube during filling with the monolithic refractory.

簡単な作業ですむ利点がある。 This mounting bracket 11 is provided on the outside of the outer shell 1 of the container, and the assembly 5 of gas blowing thin tubes 4 fixed thereto is located at a position away from the outer shell 1 of the container for high-temperature molten metal. Since it is connected to socket 7,
Its assembly and maintenance will be relatively simple. Furthermore, since it is connected to the socket 7 at a remote location, an organic binder or the like that can be used at room temperature can be used to seal the connection. Furthermore, it has the advantage of being a very simple process, such as being able to melt and seal metals with low melting points, inorganic materials, etc.
なお、２６は成形体２４を流込み等で成形して

る。 In this example, a thin tube 4 for blowing gas is arranged in advance in a molded body 24 made of a monolithic refractory, and the molded body 24 made of a monolithic refractory is inserted and set from the outside of the outer shell 1 of the container. This makes it possible to increase work efficiency. That is, the molded body 24 made of the above-mentioned monolithic refractory is inserted into the mounting opening 19 through the joint 3, and is tightened and fixed with the clasp 21 through the spacer 22. Further, even during hot operation, if there is no molten metal, the gas injection thin tube 4 can be easily assembled from the outside. Of course, it is possible to fill the outer shell of the container with the monolithic refractory without forming it into a molded body.

のである。 In addition, in FIG. 4, a cooling air inlet 15 is provided in the mounting bracket 11, and an outlet 16 is provided in the socket 7 of the assembly 5 of the thin gas inlet tubes 4.
This shows a type that cools the connection part 8 with. In the figure, the pipe 10 of the socket 7 is lengthened, and a connection part 8 with a blowing gas supply pipe (not shown) is provided on the blowing side to separate it from the thermal influence from the outer shell 1 of the container. This is designed to extend the life of the built-in structure.

る。 In this example, the mounting bracket 11 is directly attached to the metal case 26 that houses the monolithic refractory, thereby serving as a socket and pipe. This is the thin tube 4 for gas blowing.
It also serves as a protective pipe to prevent damage due to crushing, etc.
また、この例のように、連結部８は上方に向か
つて拡がつた倒立截頭円錐状のテーパ孔とすると
施工が容易となる。 Further, as in this example, if the connecting portion 8 is formed into an inverted truncated conical taper hole that widens upward, construction becomes easier.

I can do it. That is, the molded body 24 made of the above-mentioned monolithic refractory is inserted into the mounting opening 19 through the joint 3, tightened with the clasp 21, and fixed together with the spacer 22. Also,
Even during hot operation when molten metal is not flowing,
The assembly work of the gas blowing thin tube 4 can be easily performed from the outside. Of course, the monolithic refractory can be filled into the outer shell of the container without forming it into a molded body.
