【考案の詳細な説明】
本考案は、上吹、および底吹転炉のトラニオン軸受部に
おける流体供給用のスリーブに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sleeve for fluid supply in a trunnion bearing of a top-blown and bottom-blown converter.
上吹、および底吹転炉において、トラニオン軸受部のス
リーブを介して流体を供給する構造は、従来より第１図
に示すものが用いられている。In top-blown and bottom-blown converters, the structure shown in FIG. 1 has conventionally been used for supplying fluid through a sleeve of a trunnion bearing.
第１図において、１は炉体、２はトラニオンリング、６
は軸受、５はスリーブ、１２は流体供給パイプである。In Fig. 1, 1 is a furnace body, 2 is a trunnion ring, and 6
5 is a bearing, 5 is a sleeve, and 12 is a fluid supply pipe.
この従来のものではスリーブ５は軸受部６の内周部分の
みに設けであるため、その出口部１１にて配管７と溶接
、ネジ込み等の方法で接続していた。In this conventional device, the sleeve 5 is provided only on the inner peripheral portion of the bearing portion 6, so that the sleeve 5 is connected to the pipe 7 at the outlet portion 11 by welding, screwing, or the like.
ところがこの部分は炉口フードからの地金落下が多く、
カバー８を設けているが地金が大きい場合カバーを変形
し、配管に損傷を与える。However, there is a lot of metal falling from the furnace hood in this part.
Although a cover 8 is provided, if the base metal is large, the cover will be deformed and the pipes will be damaged.
このため修理に際してはカバーを外し、取外して交換せ
ねばならない。Therefore, when making repairs, the cover must be removed, removed, and replaced.
しかもこの部分は大きな防熱板１０があるためこれを撤
去してがら作業せねばならず、かつ狭い所であるため作
業が困難であるという不利があった。Moreover, since there is a large heat insulating plate 10 in this area, it is necessary to remove it while working, and the work is difficult because it is a narrow place.
本考案はこれらの欠点を解消するためになされたもので
、従来のスリーブをトラニオン軸取付部迄延長しマニホ
ルドブロック型としたところにある。The present invention was devised to eliminate these drawbacks, and consists in extending the conventional sleeve to the trunnion shaft mounting portion to form a manifold block type.
以下本考案を図面で説明する。The present invention will be explained below with reference to the drawings.
第２図において、本考案のスリーブ５′は軸受６の部分
からトラニオン軸取付部３を覆い、更にトラニオンリン
グ２の側面に迄達するマニホルドブロック型の構造とな
っていて、その内部には流体流路９が穿孔されている。In Fig. 2, the sleeve 5' of the present invention has a manifold block type structure that covers the trunnion shaft mounting part 3 from the bearing 6 and further extends to the side of the trunnion ring 2, and has a fluid flow inside. Channel 9 is perforated.
そしてトラニオンリング上面（又は下面）からスリーブ
上端面までの距離１をＯ〜５００ ｍｍにするか、もし
くは更に延長して突出させることが好ましい。It is preferable that the distance 1 from the upper surface (or lower surface) of the trunnion ring to the upper end surface of the sleeve be 0 to 500 mm, or further extended to protrude.
第３図および第４図は本考案の他の実施例を示すもので
第３図の構造においては、スリーブか斗うニオンリング
上面又は、下面より更にｌだけ突出した構造を示したも
のである。Figures 3 and 4 show other embodiments of the present invention, and the structure shown in Figure 3 shows a structure in which the sleeve protrudes further from the upper or lower surface of the onion ring by l. .
第４図は、炉体を９０°Ｃ傾転じた状態の断面図で本構
造においては、スリーブ端面がトラニオンリングの軸取
付部の端面２ａより更に横方向に１だけ延長された構造
を示すものである。Figure 4 is a cross-sectional view of the furnace body tilted by 90°C, which shows a structure in which the sleeve end face is extended by 1 in the lateral direction from the end face 2a of the shaft attachment part of the trunnion ring. It is.
これらの第３図および第４図の構造においては、スリー
ブの製作費は若干割高となるが、流路の破損は更に少な
くなると共に、メンテネナンスも非常にやりやすい構造
とすることが出来る。In the structures shown in FIGS. 3 and 4, the manufacturing cost of the sleeve is a little higher, but the damage to the flow path is further reduced, and the structure is extremely easy to maintain.
本考案は以上のような構造のスリーブを採用することに
より、炉体側配管７との取付溶接作業が容易となるため
、確実な工事が出来信頼性が高く、又万一配管及び配管
接続部に破損が生じても防熱板１０を撤去することなく
トラニオンリング上面より容易に作業が可能となり、炉
体止が短時間ですむ。By adopting the sleeve with the structure described above, the present invention facilitates the installation welding work with the furnace body side piping 7, ensuring reliable construction and high reliability. Even if damage occurs, work can be easily done from the top surface of the trunnion ring without removing the heat shield plate 10, and the furnace body can be stopped in a short time.
本考案は特に底吹転炉、上吹底吹併用転炉においては極
めて有効なものである。The present invention is particularly effective in bottom-blowing converters and top-blowing and bottom-blowing converters.
即ちこれらの転炉ではこのスリーブを通して精錬用酸素
、冷却用のプロパン、天然ガス、灯油を流通させるが、
これらは配管、及び配管接続部の破損により爆発の危険
があることと、又破損によりノズルからの溶鋼の逆流を
起し湯洩れ事故にもつながるからである。In other words, in these converters, oxygen for refining, propane for cooling, natural gas, and kerosene are passed through this sleeve.
This is because there is a risk of explosion due to damage to the piping and piping connections, and damage may cause backflow of molten steel from the nozzle, leading to a melt leakage accident.
本考案によればこれらの不安は解消されることになる。According to the present invention, these concerns will be resolved.
