Embodiment Construction

[0025] The present invention will be further described now in conjunction with accompanying drawing.

[0026] The invention provides a continuous casting tundish turbulator, which is installed under the ladle shroud and inside the tundish. Such as figure 1 As shown, the external structure of the turbulator is an octagonal prism 1, and three bosses 2 are distributed on its eight cylinders at intervals. A cylinder, set the first boss on this cylinder, set the second boss at two cylinders in the clockwise direction, and then set the third boss at one cylinder; three bosses 2 in When the tundish is built, it is built into the bottom of the tundish, which can effectively fix the turbulence device, prevent the turbulence device from floating in the early stage of use of the tundish, and ensure that the turbulence device does not float after the tundish is used in the later stage of use.

[0027] Such as figure 1 and figure 2 As shown, the inside of the turbulator is a cavity, t...

Abstract

The invention relates to a continuous casting tundish turbulator. The external structure of the tundish is an octagonal prism (1), with three bosses (2) spaced on its eight cylinders; the interior of the tundish is is a cavity, the inner side of the cavity is a paraboloid of rotation (3), eight guide holes (4) are evenly distributed on the inner wall of the cavity, and the bottom of the cavity is a paraboloid of rotation (3) at the center of the bottom 5), eight small paraboloids (6) are evenly distributed along the outside of the bottom center rotating paraboloid (5); the turbulator of the present invention has the advantages of enhanced metallurgical function, prevention of floating and long service life.

Description

technical field [0001] The invention relates to iron and steel metallurgical equipment, in particular to a continuous casting tundish turbulence device. Background technique [0002] The continuous casting tundish is the transition device between the ladle and the mold, and the last link before the molten steel enters the mold, which is of great significance to ensure the quality of the continuous casting slab. Since the "tundish metallurgy" technology was proposed in the early 1980s, with the development of continuous casting technology, its role has received more and more attention, and it has now developed into a special comprehensive out-of-furnace metallurgy technology. The "tundish metallurgy" technology improves the flow conditions of molten steel, reduces the occurrence of short-circuit flow and dead zones, improves the flow direction and prolongs the path, and provides favorable conditions for the floating of inclusions in molten steel, thereby ensuring the purity o...
