作業が大変であつた。 A large amount of slag adheres to the outer circumferential surface of a molten metal immersion tube, such as a immersion tube attached to a vacuum degassing tank, while it is immersed in a ladle. Conventionally, the immersion pipe section was first cooled, a slag removal rod was placed against the sludge and supported manually, the slag removal rod was driven up and down by a lifting mechanism to remove the sludge, and a replacement stand was attached to the immersion tube. The dip tube is then removed from the vacuum degassing tank and another dip tube is attached to the vacuum degassing tank. Cooling is performed by an air cooling fan, and sludge removal is carried out by placing a sludge removal jig with teeth on the upper end on a traveling trolley, supporting it manually, and driving it upwards with a hydraulic cylinder. After removing the sludge, the sludge removing jig on the traveling truck is lowered and a dipped tube replacement stand is placed on it, and the dipped tube is supported by this pedestal, and then the dipped tube is removed from the vacuum degassing tank. Therefore, in the past, sludge removal was dangerous and labor-intensive, and it was difficult to attach the sludge removal jig to the traveling truck and to replace the sludge removal jig with the replacement frame.

2の上表面に乗つている。 FIG. 1 shows an embodiment of the present invention. In FIG. 1, a flange 3 of a cylindrical crown 2 having a ring-shaped deposit removal tooth 1 is fixed to an upper flange 22 of a cylindrical main body 4. As shown in FIG. A water cooling pipe 11 is wound around the outside of the cylindrical body 4, and the lower end is fixed to a cylindrical pedestal 5. Four spring seats 6 are fixed to the outside of the cylindrical pedestal 5. A coil spring 7 in the body 6 is received by an air discharge platform 8 of an air pallet.
A ring-shaped block 10 for receiving the lower end of the immersion tube 9 is fixed to the upper surface of the air discharge table 8.
The air release table 8 is the air receiving table 1 of the air pallet.
It rests on the upper surface of 2.

に取り付ける。 The air pedestal 12 is fixed on a lifting table 14 of a traveling carriage 13. The lifting table 14 is
It is guided in a vertically movable manner by a lifting guide 15 of a traveling carriage 13, and is supported by piston rods of hydraulic cylinders 16 1 and 16 2 . 17 is a motor for driving the vehicle, and 18 is a handle for operating the air pallet. Next, to explain the operation, the hydraulic cylinder 16 1 ,
After removing the pressure oil from the hydraulic cylinders 16 2 and lowering the table 14, the starting cart 13 is positioned below the vacuum degassing tank 19. Next, while supplying pressure oil to the hydraulic cylinders 16 1 and 16 2 , the air pallet is removed. Operate the operating handle 18 to release the air release table 8 to the air receiving table 12.
The air release table 8 is slidably connected to the air receiving table 1.
2 to position the crown 2 directly below the dip tube 9. As a result, the crown 2 rises in such a manner that the dipping tube 9 passes through the crown 2, and hits the base metal or slag attached to the outside of the dipping tube 9, thereby peeling it off. If the bare metal and slag are not removed sufficiently in one lift, drain a little pressure oil from the hydraulic cylinders 16 1 and 16 2 , lower the tooth crown 2 a little, and energize the air pallet to rotate the tooth crown 2 a little. The table 14 is then raised again. After removing the slag in this way, the table 14 is raised and the tip of the tooth 1 is brought into contact with the flange 21 of the immersion tube 9, so that the coil spring 7 is compressed and the upper end of the block 10 approaches the lower end of the immersion tube 9. to stop table 14 from rising. Then, the flange 21 of the dip tube 9 is removed from the flange 20 of the vacuum degassing tank 19. At this time, the coil spring 7 is further compressed by the weight of the immersion tube 9, and the lower end of the immersion tube 9 comes into contact with the upper end of the block 10, and the immersion tube 9 is supported by the crown 2 and the block 10. The coil spring 7 thus acts as a cushion material supporting the dip tube 9. Next, drive the traveling trolley to lower the dip tube 9 at another location, place another dip tube on it, return the traveling trolley to the vacuum degassing tank 19, and place the dip tube in the tank 19.
