Abstract
The utility model discloses a current stabilizer of a continuous casting pouring basket of which the structure is in shape of a container with a hollow inner chamber. The bottom portion of the inner chamber of the current stabilizer is big, while the mouth part of the inner chamber of the current stabilizer is small. The current stabilizer of the continuous casting pouring basket which employs the structure capable of avoiding molten steel slag entrapment of an entry nozzle area of a ladle with obvious and stable effect, and the pouring basket is high in quality of the molten steel and low in consumption of fireproof material.
Description
The utility model relates to a kind of constant-current stabilizer of continuous casting tundish, belongs to Ferrous Metallurgy continuous casting field.
In casting process, molten steel in the ladle constantly flows in the tundish, because the kinetic energy effect of molten steel, the MOLTEN STEEL FLOW rather unstable in ladle nozzle zone, slag often is involved in the molten steel, cause continuous casting billet internal soundness defective, for preventing the generation of this phenomenon, at present, in the steel ladle pouring zone of tundish, generally take to be provided with the way of shock plate, stiffener and barricade, pouring molten steel is in the space that shock plate, stiffener and barricade surround, spill in the tundish through barricade, the impact of alleviating molten steel is seethed again.The setting of barricade, the molten steel volume slag phenomenon that the reduction steel ladle pouring causes is played a role, but also exist the unsettled shortcoming of effect simultaneously, barricade constantly is subjected to the erosion of washing away of molten steel in the process of cast, it is more and more shorter that barricade can become, the effect of barricade is just not obvious behind the cast certain hour, even do not worked.In addition, because the impact erosion that shock plate directly bears molten steel connects under the situation of drawing time length at continuous casting billet, cause the generation of wearing the bag accident easily, adopt this way, the refractory consumption rate that barricade, shock plate etc. use is bigger.
The purpose of this utility model is to provide a kind of continuous casting tundish flow straightener that prevents that ladle nozzle zone molten steel volume slag effect is obvious, stable, refractory consumption rate is low.
The utility model is achieved in that this flow straightener structure is the container-like structure with hollow lumen, and the big oral area of flow straightener intracavity bottom is little.
As further improvement of the utility model, the longitudinal section of this flow straightener inner chamber is divided into two sections, and the outlet position is a flat segments, and the bottom surface is a contraction section to exporting the position, and the bottom is big, and is more upwards more little, adopts rounding off to be connected between contraction section and the flat segments.
The utility model has the advantages that: the tundish flow straightener adopts the structure of container of hollow lumen, and the bottom is big, oral area is little, be collapsed shape, pouring molten steel is in flow straightener, upwards overflowed by oral area along chamber wall, steady flow result is good, and molten steel inclusion floating situation is good, the steel quality height, by design suitable containers height and chamber wall thickness, can make the long enough in service life of flow straightener, molten steel is all the time by overflowing in the flow straightener, can guarantee stable steady flow result, it is stable to prevent to roll up slag, and in addition, the refractory consumption of using the flow straightener tundish is low.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model cutaway view.
Fig. 2 is the A-A view of Fig. 1.
As shown in Figure 1, tundish flow straightener inner chamber is divided into two parts, exit portion is a flat segments 1, the bottom is a contraction section 2 to exit portion, more upwards more little, contraction section 1 is a rounding off with outlet section 2 junctions, to reduce the impact erosion of molten steel to flow straightener, the current stabilization wall is more and more thicker from bottom to top, adapt to molten steel to the increasing from bottom to top requirement of the impact of current stabilization wall, the wall thickness of flow straightener, height are set according to actual production requirement and steady flow result, and the flow straightener outer shape is definite according to the impact zone position of tundish, generally manufacture to be cuboid.
Shown in Figure 2, flow straightener inner chamber shape of cross section is, the two ends semicircle middlely is the straight line connection, and the design of flow straightener cavity shape, position is well a principle with all even steady flow result of wall thickness.
Claims (2)
1. continuous casting tundish flow straightener, it is characterized in that: this flow straightener structure is the container-like structure with hollow lumen, and the big oral area of flow straightener intracavity bottom is little.
2. continuous casting tundish flow straightener according to claim 1, it is characterized in that: the longitudinal section of described flow straightener inner chamber is divided into two sections, the outlet position is flat segments (1), the bottom surface is contraction section (2) to exporting the position, the bottom is big, more upwards more little, the employing rounding off is connected between contraction section (2) and the flat segments (1).
