Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking and continuous casting, in particular to a novel tundish plugger hanger. Background Art

[0002] There are currently two ways to control the flow of the tundish of the continuous casting machine: one is the tundish stopper control, and the other is the sliding nozzle control. In the tundish stopper control method, due to improper installation of the stopper and poor quality of refractory materials, it is easy to cause the stopper to break, turn around, and crack. If it is discovered in time before pouring, the accident can be avoided in time by replacing the stopper. However, when replacing the stopper, the stopper is lifted by directly lifting the stopper and the mechanism together with a wire rope, which causes the stopper to break, the mechanism to deform, or the mechanism to be placed too large during the lifting process, affecting the personal safety of employees at the post.

When in use, the threaded section of the stopper rod 7 is passed through the through hole 4, and then the stopper rod 7 is clamped and locked by the locking nuts 10 on the upper and lower sides, and then the stopper rod 7 is adjusted. The distance between the telescopic rods 22 is adjusted, and the clamps 21 on both sides are connected by connecting bolts 9, so as to realize the clamping effect on the upper end of the stopper rod 7, effectively preventing the upper end of the stopper rod 7 from swinging during the lifting process, and also reducing the force on the locking nut 10. After passing through the through hole 4, the stopper rod 7 continues to extend, thereby passing through the limit ring 32. Under the action of the limit ring 32, the restriction effect on the lower end of the stopper rod 7 is realized, effectively preventing the lower end of the stopper rod 7 from swinging during the lifting process. Then, the U-shaped rings 8 at both ends of the lifting belt 6 are buckled onto the lifting holes 11, and the electric hoist is used to lift the entire lifting device through the lifting belt 6, so as to realize the lifting of the stopper rod 7. The use of this lifting device can effectively avoid the problems of large swing amplitude of the stopper rod 7 and breakage of the stopper rod 7 during the lifting of the stopper rod 7, thereby ensuring safe production, stable and smooth operation.
