The technical solution of the utility model is achieved in that the anti-floating flow straightener of the anti-turbulent flow of a kind of tundish, be shaped as spittoon shape, form the ring outer surface V-shaped groove in one week near horizontal outer bottom (11) position by the conical surface and inverted cone surface on the outer surface, inner surface is by a horizontal inner bottom surface (1), one from above-mentioned horizontal inner bottom surface (1) periphery outside upwardly extending transition sphere (2), a cylinder (3) that upwards vertically extends from above-mentioned transition sphere (2) top edge, one from above-mentioned cylinder (3) the inside upwardly extending transition conical surface in top (4), one upwards extends perpendicularly to the smooth connection of the formed cylinder of upper horizontal surface (6) (5) order from the above-mentioned transition conical surface (4) upper end and forms.Outer surface is to be extended to the smooth connection of the formed cylinder of upper surface (6) (7) order vertically upward from above-mentioned inverted cone surface (8) top edge and form from make progress outward-dipping inverted cone surface (8), one of the above-mentioned conical surface (9) top edge from above-mentioned outer bottom (11) periphery make progress from above-mentioned cylinder (10) the upper end intilted conical surface (9), one of vertically extending cylinder (10), that make progress by a horizontal outer bottom (11), one.
Further preferred version is:
On the outer surface, cylinder (10) upper end is 30～50mm apart from the vertical range of outer bottom (11).
On the outer surface, cylinder (10) upper end is 40mm apart from the vertical range of outer bottom (11).
On the outer surface, the conical surface (9) is 30～45 ° with the angle of horizontal plane.
On the outer surface, the conical surface (9) is 40 ° with the angle of horizontal plane.
On the outer surface, the conical surface (9) is 95～105 ° with the angle of inverted cone surface (8).
On the outer surface, the conical surface (9) is 100 ° with the angle of inverted cone surface (8).
On the outer surface, the conical surface (9) top edge and inverted cone surface (8) top edge horizontal range are 25～35mm.
On the outer surface, the conical surface (9) top edge and inverted cone surface (8) top edge horizontal range are 30mm.
The beneficial effects of the utility model are: the utility model is by means of the design of the conical surface and the inverted cone surface formation V-shaped groove of close bottom position on the outer surface, prevent that effectively flow straightener is floating in steel pouring process, and V-shaped groove is to cave inward, keeping under the constant substantially situation of flow straightener wall thickness, it is bigger relatively to make that flow straightener inner chamber aperture can be done, and then can to a certain degree prevent to water in the steel pouring process partially.
