Abstract
The invention relates to a continuous casting tundish, in particular to a continuous casting tundish asymmetrical turbulent flow controller. The outline structure is a cube, and the interior is a cavity structure with a groove; the bottom surface of the cavity is a wavy surface; and the central line of a semicircular protrusion in the middle of the wavy surface does not coincide with the central line of the inner cavity. The invention improves the homogenization of molten steel temperature and components, reduces the process cost and effectively removes non-metal impurities, thereby improving the quality of a casting blank.
Description
Technical field
The present invention relates to the continuous casting tundish, be specifically related to the asymmetric turbulence inhibitor of a kind of continuous casting tundish.
Background technology
Present continuous casting tundish turbulence inhibitor, profile is used frustum structure or cube structure, and wherein frustum structural turbulence controller has a central symmetry axis, and the cube structure turbulence inhibitor respectively has a plane of symmetry in length and width.The turbulence inhibitor of said structure can be realized the homogenization of each flow export molten steel temperature of symmetric form tundish and composition well, but can not satisfy the homogenization requirement of each flow export molten steel temperature of asymmetric tundish and composition.
Summary of the invention
Problem at present continuous casting tundish turbulence inhibitor exists the invention provides the asymmetric turbulence inhibitor of a kind of continuous casting tundish.Solve the problem of each flow export molten steel temperature of asymmetric tundish and composition homogenization effectively.
The asymmetric turbulence inhibitor of continuous casting tundish of the present invention, contour structures is a cube, and inside is cavity structure, and main points are that described internal cavities is fluted, the bottom surface of cavity is a wavy surface, and the center line of the half-circle projection in the middle of the wavy surface does not overlap with the center line of internal cavities.
Described wavy surface has three semicircular projections and two semicircular depressions.
Described internal cavities is suitable for reading to be that circle, rectangle, ellipse or centre are rectangle, and both sides are semicircle.
The beneficial effect of the present invention's outstanding feature and generation compared with prior art is: improved the homogenization of molten steel temperature and composition, reduced the technology cost, effectively removed non-metallic inclusion, improved the quality of strand.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the front view of continuous casting tundish;
Among the figure: 1 cavity is suitable for reading, 2 wavy surfaces, 3 continuous casting tundish, 4 ladle long nozzles, 5 right barricades, the mouth of a river, 6 left side, the mouth of a river, 7 right side, 8 left barricades.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
The asymmetric turbulence inhibitor of example 1. continuous casting tundish of the present invention, contour structures is a cube, inside is cavity structure, internal cavities is fluted, cavity suitable for reading 1 is a rectangle, the bottom surface of cavity is a wavy surface 2, and the center line of the half-circle projection in the middle of the wavy surface 2 does not overlap with the center line of internal cavities, and the center line of the half-circle projection in the middle of the center line of ladle long nozzle 4 and the wavy surface 2 coincides.
Ladle long nozzle 4 departs from continuous casting tundish 3 center line 805mm, and the mouth of a river, left side 6 is apart from ladle long nozzle 4 center line 2250mm, and the mouth of a river, right side 7 has right barricade 5 and left barricade 8 apart from ladle long nozzle 4 center line 3860mm respectively in the both sides of turbulence inhibitor.The wavy surface 2 of cavity floor has three semicircular projections and two semicircular depressions.The center line of middle semicircular projection and the center line of ladle long nozzle 4 coincide.Under the effect of molten steel ladle potential energy, the molten steel that is flowed out by ladle long nozzle 4 is by the turbulence inhibitor that enters suitable for reading of turbulence inhibitor, impact the turbulence inhibitor bottom to around scatter after, move upward along turbulence inhibitor, pass through turbulence inhibitor outflow turbulence inhibitor suitable for reading at last.Turbulence inhibitor at the cavity volume on ladle long nozzle 4 center line right sides greater than the left side cavity volume, therefore the mobile to the right resistance ratios left side that is subjected to of molten steel is little, can guarantee at the turbulence inhibitor molten steel flow that is positioned at ladle long nozzle 4 center lines left sides suitable for reading little like this, the molten steel flow that is positioned at ladle long nozzle 4 center line right sides is big, thereby realize the asymmetric distribution of molten steel, satisfied the homogenization requirement of each flow export molten steel temperature of asymmetric tundish and composition.
Example 2. its structures, connection is identical with embodiment 1 with the course of work, and difference is that cavity suitable for reading 1 is for circular.
Example 3. its structures, connection is identical with embodiment 1 with the course of work, and difference is that cavity suitable for reading 1 is for oval.
Example 4. its structures, connection is identical with embodiment 1 with the course of work, and difference is to be rectangle in the middle of the cavity suitable for reading 1 that both sides are semicircle.
Claims (3)
1. asymmetric turbulence inhibitor of continuous casting tundish, contour structures is a cube, and inside is cavity structure, it is characterized in that described internal cavities is fluted, the bottom surface of cavity is a wavy surface, and the center line of the half-circle projection in the middle of the wavy surface does not overlap with the center line of internal cavities.
2. the asymmetric turbulence inhibitor of a kind of continuous casting tundish as claimed in claim 1 is characterized in that described wavy surface has three semicircular projections and two semicircular depressions.
3. the asymmetric turbulence inhibitor of a kind of continuous casting tundish as claimed in claim 1 is characterized in that described internal cavities is suitable for reading for circle, rectangle, ellipse or centre are rectangle, and both sides are semicircle.
