Next, the operation of this embodiment will be explained. Before converter blowing, the oil pressure inside the cylinder 35 is adjusted in advance so that the piston 3
6 is advanced, and the skirt device 30 is lowered to position this device 30 at the blowing position. In this case, since the solidified molten steel 70 is attached to the furnace mouth 22 of the converter 21, the portion of the upper pipe 32b of the cooling water flow pipe 32 closest to the converter is pressed against the solidified molten steel 70. It will be done. Then, the upper tube 32b can move upward by the length of the engaging member 55, so there is less risk of the portion of the upper tube 32b pressed against the solidified molten steel 70 being damaged or deformed. Moreover, since each upper tube does not come into contact with other adjacent upper tubes, there is no possibility that the upper tubes will be pressed against each other by other upper tubes. Furthermore, since each upper pipe is divided into four pipe members, if solidified molten steel is locally attached, only the pipe member corresponding to the part to which the solidified molten steel is attached can be moved up and down. I can do it. Therefore, the risk of damage to the upper tube can be further reduced.

After the blowing is completed, the oil pressure in the cylinder 35 is adjusted to move the piston 36 back and forth, and the skirt device 30 is raised to the converter moving position. In this state, the converter is tilted to tap the molten steel in the converter.
