The four groups of workbench supporting legs 11 are evenly distributed on the lower surface of the balancing workbench 10. The purpose of setting multiple groups of workbench supporting legs 11 is to effectively support the auxiliary argon blowing device so that the auxiliary argon blowing device is in the best argon outlet position.

[0029] See also Figure 2 A position control guide single rod 3 is fixedly arranged inside the component protective shell 2. There are two groups of position control guide single rods 3. Both ends of the two groups of position control guide single rods 3 are fixedly arranged inside the component protective shell 2.

[0032] Working principle: During the continuous casting process, the molten steel flows from the ladle body 16 to the tundish body 18 to the subsequent crystallizer. The sleeve body 17 with argon seal is used between the ladle body 16 and the tundish body 18. At this time, the external argon gas pipeline is connected to the argon gas connection module 14, and the control valve 15 is opened to allow the argon gas to pass through the argon blowing ventilation hard pipe 1 through the argon blowing head 12 and discharge from the argon hole 13 to the specified position, thereby effectively controlling the aluminum loss and nitrogen addition, and greatly improving the gas component hit rate of the steel variety. At this time, the argon blowing ventilation hard pipe 1 is in the middle of the component protective shell 2, through The external power causes the external control turntable 6 to rotate, so that the one-way screw rod 5 pushes the hard tube clamping module 4 to move horizontally on the control position guide single rod 3, so that the two groups of hard tube clamping modules 4 are in close contact with the argon blowing ventilation hard tube 1, thereby effectively fixing the argon blowing ventilation hard tube 1 for use, reducing the work intensity of the staff holding it, and pushing the linkage balance bottom plate 7 by external force. Through the mutual restriction between the linkage control position module 8 and the guide control position track 9, the position of the argon blowing ventilation hard tube 1 in the component protective shell 2 can be effectively changed, making the auxiliary argon blowing device more practical.
