In this embodiment, by adding the first hydraulic cylinder 22, the first hydraulic cylinder 22 drives the connecting rod 21, and then drives the lifting ring block 24 to lift, so that the RH furnace body 1 is lifted to a certain height, the cooling immersion pipe 4 is aligned and the position is cooled.

[0028] like Figure 5 、 Figure 6 As shown, the cooling unit includes a cooling bin 17, an exhaust hole 18, an air inlet hole 19, and a fan 20. The output end of the second hydraulic cylinder 23 is welded with the cooling bin 17, and the side wall of the cooling bin 17 is provided with an air inlet hole 19. The side wall of the cooling bin 17 opposite to the air inlet hole 19 is provided with an exhaust hole 18. The inner wall corresponding to the air inlet hole 19 is rotatably connected to the fan 20.

[0035] When the immersion pipe 4 needs to be cooled, the button on the control panel 14 is used to control the first hydraulic cylinder 22 to drive the connecting rod 21, thereby driving the lifting ring block 24 to lift, so that the RH furnace body 1 is lifted to a certain height. When the laser ranging sensor 12 detects the distance to the immersion pipe 4, the second cylinder is controlled to drive the cooling chamber 17, so that it moves to the vicinity of the immersion pipe 4 and turns on the fan 20 to cool the immersion pipe 4. When the infrared temperature sensor 13 detects that the temperature of the immersion pipe 4 has been cooled, the fan 20 is turned off, and the operator is prompted to proceed to the next step through the control panel 14.
