Anti-floating device for tundish turbulence promoter

The utility model relates to the technical field of ferrous metallurgy, and provides an anti-floating device for a tundish turbulence promoter. The anti-floating device comprises a lining protection board which is arranged between a tundish working layer and the turbulence promoter, wherein the outer wall of the lining protection board is attached to the inner wall of the tundish working layer; the bottom of the inner wall of the lining protection board is provided with a groove corresponding to the turbulence promoter; the turbulence promoter is a rectangular; the upper edge of the turbulence promoter is provided with a rectangular through hole in the height direction; the turbulence promoter is positioned in an impact zone on the inner bottom surface of a tundish; the turbulence promoter is embedded into the groove. By adopting the anti-floating device for the tundish turbulence promoter provided by the utility model, the problem of floatation of the turbulence promoter due to the floating force of molten steel on the outer surface of the turbulence promoter in a steel casting process is solved.
