During the moving process, the damping honeycomb cylinder 6 and the blocking baffle 9 of the blocking damping assembly 2 will disperse the impact force of the molten steel and reduce the liquid level oscillation; the conical blocking cover 11 and the damping honeycomb ring 13 of the damping splash-proof assembly 3 further suppress the splashing, after the casting is completed, the residual molten steel in the ladle body 1 is cleaned in time, whether each assembly is intact is checked, and preparation for next use is made.

[0021] Specifically, the damping honeycomb cylinder 6 on the blocking damping assembly 2 is fixedly installed on the inner wall of the ladle body 1, the damping honeycomb cylinder 6 is provided with a honeycomb hole, the damping honeycomb cylinder 6 and the connecting rod 8 on the blocking damping assembly 2 are fixedly connected, the inner end of the connecting rod 8 is provided with a connecting clamping groove 10, and the blocking baffle 9 on the blocking damping assembly 2 is inserted into the connecting clamping groove 10 provided at the inner end of the connecting rod 8.
