Abstract
The utility model discloses a slab continuous casting tundish, which comprises a concave tundish body; wherein, one side of the tundish body is a steel-pouring side; the other side of the tundish body is a steel-pouring opening side; a steel-pouring opening is arranged on the bottom of the tundish body of the steel-pouring opening side; a slag-blocking wall is arranged close to the steel-pouring side in the tundish body; a diversion opening is arranged between the slag-blocking wall and the bottom of the tundish body; two slag-blocking dams are arranged between the slag-blocking wall and the steel-pouring opening; a circulating opening is arranged on the slag-blocking dam close to one side of the steel-pouring opening; one end of the circulating opening faces the steel-pouring side; and the other end of the circulating opening faces the steel-pouring opening side. The utility model can improve the quality of the produced steel product, and moreover, the finished product rate of molten steel is high, so that the cost can be reduced.
Description
Technical field
The utility model belongs to smelts the casting field, is specifically related to a kind of sheet billet continuous casting tundish.
Background technology
Smelting the casting field, in the sheet billet casting cycle, can not online replacing continuous casting tundish because of the characteristics of its quick cooling and shaping, cause its quantity of using tundish to be much higher than conventional conticaster, thereby make the finished product rate of molten steel also be starkly lower than conventional conticaster.At present, the continuous casting tundish major part that most of thin-slab caster adopted is the rectangle inclusion, the inclusion of indent wherein a side for watering the steel side, opposite side is for watering the steel oral-lateral, be provided with in the inclusion bottom of watering the steel oral-lateral and water the steel mouth, be provided with slag blocking wall near watering the steel side in inclusion, slag blocking wall is provided with flow-guiding mouth between bottom inclusion, at slag blocking wall and water and be provided with two dams between the steel mouth.In continuous casting production process, the effect of tundish is to receive the molten steel that ladle flows into, and to crystallizer injection molten steel, it makes molten steel shunt, reduced the impact of molten steel, adopted the technology of Buffer Pool, played the effect that separates field trash to a certain extent at the inside of tundish distribution dam to crystallizer, preventing effectively that the slag of tundish flow in the crystallizer when watering eventually goes, thereby produces the steel product of high-quality.
But, the filling remaining liquid steel amount is more in the tundish also can influence the molten steel finished product rate, what play pushing off the slag and restriction tundish filling remaining liquid steel amount in tundish is dam, in the prior art, what the continuous casting tundish used is whole dam, and the two all must have certain height, the gap, bottom that promptly will be higher than slag blocking wall, such structure more can effectively be separated the field trash in the molten steel on the one hand, but make the liquid level of filling remaining liquid steel in the tundish can not be lower than the height of dam on the other hand, just the filling remaining liquid steel amount of tundish must remain on the higher tonnage when watering eventually, thereby cause the filling remaining liquid steel amount too much, thereby reduce the molten steel finished product rate, increase manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of sheet billet continuous casting tundish, and this tundish can improve the quality of the steel product of producing, and molten steel finished product rate height, to reduce cost.
The utility model is achieved through the following technical solutions:
A kind of sheet billet continuous casting tundish, the inclusion that comprises indent, a wherein side of inclusion is for watering the steel side, opposite side is for watering the steel oral-lateral, be provided with in the inclusion bottom of watering the steel oral-lateral and water the steel mouth, be provided with slag blocking wall near watering the steel side in inclusion, slag blocking wall is provided with flow-guiding mouth between bottom inclusion, at slag blocking wall and water and be provided with two dams between the steel mouth; Be provided with communication port near the described dam that waters steel mouth one side, this communication port one end is towards watering the steel side, and the other end is towards watering the steel oral-lateral.
Described communication port is nick shaped or poroid.
Described communication port is at least two.
Described communication port is uniform on described dam.
On described communication port, be equiped with the metal derby that adapts with its shape.
Described communication port is cylindrical, corresponding, and described metal derby also is cylindrical.
Before casting, adopt metal derby to block communication port earlier, molten steel waters the steel side from inclusion and enters in the inclusion, and flow out through the flow-guiding mouth of slag blocking wall bottom, behind two dams, flow out from watering the steel mouth more successively, the utility model adopts the Buffer Pool technology, and the impurity in the molten steel blocks through slag blocking wall, dam, has improved the quality of steel product.Water through one time water steel after, be blocked in metal derby on the dam communication port and can meet high temperature and melt, after casting is finished, remaining molten steel just from communication port, water the steel mouth and flow out, and reduce the amount that remains molten steel, improve the molten steel finished product rate, to reduce manufacturing cost.

The specific embodiment
As shown in Figure 1, 2, a kind of sheet billet continuous casting tundish, the inclusion 1 that comprises indent, a wherein side of inclusion 1 is for watering the steel side, opposite side is for watering the steel oral-lateral, is provided with in inclusion 1 bottom of watering the steel oral-lateral and waters steel mouth 5, is provided with slag blocking wall 2 near watering the steel side in inclusion 1, be provided with flow-guiding mouth 3 between slag blocking wall 2 and inclusion 1 bottom, at slag blocking wall 2 and water and be provided with two dams 4 between the steel mouth 5; Be provided with communication port 6 near the dam 4 that waters steel mouth 5 one sides, these communication port 6 one ends are towards watering the steel side, and the other end is towards watering the steel oral-lateral.
Wherein, communication port 6 is two, and these two communication port 6 are uniform on dam 4, and it is poroid that communication port 6 is cylinder, before casting, adopt columned metal derby to block communication port 6 earlier, molten steel waters the steel side from inclusion 1 and enters in the inclusion 1, and flows out through the flow-guiding mouth 3 of slag blocking wall 2 bottoms, behind two dams 4, flow out from watering steel mouth 5 more successively, the Buffer Pool technology is adopted in this enforcement, and the impurity in the molten steel blocks through slag blocking wall 2, dam 4, has improved the quality of steel product.Water through one time water steel after, be blocked in metal derby on dam 4 communication port 6 and can meet high temperature and melt, after casting is finished, remaining molten steel just from communication port 6, water steel mouth 5 and flow out, and reduce the amount that remains molten steel, improve the molten steel finished product rate, to reduce manufacturing cost.
