Ａに直接浸漬されるために溶損摩耗が激しく、そ
の溶損部分Ｂは必要に応じて補修されている。"Prior art" and "problems" A degassing tank (RH degassing tank) as shown in Figure 2
Since the immersion tubes 2a and 2b at the lower end of the tube are directly immersed in molten steel A at about 1600°C, they are subject to severe erosion and wear, and the erosion-damaged portion B is repaired as necessary.
第３図は上記溶損部分Ｂの補修を吹付で行うた

の昇降を制御することによつて浸漬管の補修を行
うようになつているのである。 FIG. 3 schematically shows a conventional apparatus for repairing the melted portion B by spraying. That is, on the lifting table 40 of the table lifter 4, the nozzle pipe 5 with the outlet 5' opening in one or both horizontal directions is placed upright so as to be rotatable, and the nozzle pipe 5 is rotated. While being rotated by the device 6, the refractory raw material is spouted from the outlet 5', and the control device 43 controls the table lifter 4.
The immersion pipe can now be repaired by controlling the lifting and lowering of the pipe.

ａ，２ｂの下端部では施工体の面と吹付方向とが
直角にならず、材料のリバウンドが生じて付着率
が悪くなる欠点がある。 However, with this device, when the repaired surface is perpendicular to the blowing direction from the outlet 5', the refractory material can be effectively attached to the repaired surface of the construction body (immersion pipe). Like dip tube 2
At the lower ends of a and 2b, the surface of the workpiece and the direction of spraying are not perpendicular to each other, resulting in material rebound and poor adhesion.
上記欠点を解消するために、ノズル管の先端部
に変角機構を設けて、吹出口からの吹出方向を変
角し得る吹付装置が開発され、一部実用化されて
いるが浸漬管内部は高温（700〜800℃）であり、
また、吹付時にダスト、あるいはシストが発生す
るので上記変角機構に故障が多発していたのであ
る。 In order to eliminate the above drawbacks, a blowing device was developed in which a bending mechanism was installed at the tip of the nozzle pipe to change the direction of the blowout from the blowout port. High temperature (700-800℃)
Furthermore, since dust or cysts are generated during spraying, the angle-changing mechanism frequently fails.

る。 In addition, in Japanese Utility Model Application Publication No. 57-116762, in order to improve the adhesion rate of monolithic refractories, the repaired part of the immersion pipe is covered with a wire mesh held by a predetermined holding means, and then A repair device configured to supply monolithic refractories under pressure is disclosed. However, in the above device, the shape of the wire mesh must be manufactured to match the shape of the immersion tube to be repaired, and the operator must visually check the position of the wire mesh with respect to the end of the immersion tube or the vertical distance of the wire mesh. It is necessary to make decisions and operate the equipment, which has the disadvantage that it does not necessarily lead to more efficient repair work.
そこで最近ではパツチング補修や圧着補修が行
われるようになつている。 Therefore, patching repairs and crimping repairs have recently become popular.
しかしながらパツチング補修は第５図に示すよ
うに作業者が厚い手袋をはめて700℃〜800℃の浸
漬管の下部の摩耗部へ手でプラスチツク耐火原料
を圧付肉付けする方法であるので、作業に危険が
伴う欠点があつた。 However, as shown in Figure 5, patching repair is a method in which the worker puts on thick gloves and manually presses and fills the worn part of the lower part of the immersion tube at 700°C to 800°C with plastic refractory material, so it is difficult to perform the work. It had some dangerous drawbacks.
そこで、第６図に示すような圧着補修が主流に
なつていたのである。すなわち、浸漬管２ａ，２

３１内に、プラスチツク耐火原料Ｃを詰め込んで
おいて該容器を圧縮器（図外）で浸漬管下端部に
押圧し、そのまま使用するのである。 Therefore, crimping repairs as shown in FIG. 6 became mainstream. That is, the dip tubes 2a, 2
The plastic refractory raw material C is packed into a donut-shaped iron plate container 31 that is slightly larger than the end surface of the tube b, and the container is pressed against the lower end of the immersion tube using a compressor (not shown) and used as is.
しかしながら。この方法は表面が鉄板用に３１

となつて脱落が生じる欠点がある。 however. This method is suitable for iron plate surfaces.
Since it remains covered with molten steel, it is difficult for moisture to escape and it is difficult to solidify, and it also has the disadvantage that if it is immersed in molten steel before it is sufficiently solidified, it will become separated and fall off.

るのである。 Next, the table lifter 4 is operated to raise the outlet 5' of the nozzle, but at the same time as the pressure switch 11 is turned off and the lifting starts, the switching valve 10 as a switching means is activated. The actuator is activated and the auxiliary plate 30 is in a state where it can be lowered. (In reality, the absolute position of the auxiliary plate 30 does not change, but the distance between the auxiliary plate 30 and the table 40 becomes smaller.) Then, the table lifter 4 is further raised and provided as another contact pressure adjustment means. The pressure preset in the pressure regulating valve 9 (e.g. 20Kg/
cm 2 ) (at this time, the auxiliary plate 30 receives 50 kg/cm 2 , which is the sum of the pressure of 30 kg/cm 2 from the hydraulic cylinders 3 to 3 and the pressure of 20 kg/cm 2 from the table lifter 4. ) The pressure in the hydraulic cylinders 3 to 3 begins to decrease, and the distance between the auxiliary plate 30 and the table 40 of the table lifter 4 decreases at a speed adjusted in advance by the lowering speed adjustment valve 13.
At this time, the auxiliary plate 30 remains pressed against the end of the immersion tube with a pressure of 50 kg/cm 2 , and conversely, the outlet 5' of the nozzle pipe 5 moves upward within the immersion tube.
