Abstract
The invention provides a tundish of a slag baffling device containing a liquid outlet, comprising a tundish body, a liquid inlet at the upper end of the tundish body, and a liquid outlet at the lower end of the tundish body, wherein the slag baffling device covers the liquid outlet, the slag baffling device is a conical hollow base body, and the surface of the conical hollow base body is uniformly provided with a plurality of through holes. The slag baffling device covers the liquid outlet, so that a vortex is effectively prevented from being generated, the purity degree of molten steel is improved and the quality of products is improved.
Description
Technical field
The present invention relates to the refractory material container tundish of steelmaking equipment, relate in particular to a kind of liquid outlet skimming device tundish that contains.
Background technology
Tundish is as the most general a kind of refractory material container of field of steel-making; Present tundish on the market generally includes only inclusion, the inlet of inclusion upper end, the liquid outlet of inclusion lower end, in the steelmaking converter smelting process, because of molten metal continuous-flow; Form whirlpool easily at the liquid outlet place; Eddy current together is involved in the regulus in the molten metal and other foreign material in the casting embryo, has had a strong impact on the quality of steel billet, haves much room for improvement.
Summary of the invention
The present invention is directed to the prior art deficiency, provide a kind of minimizing liquid outlet eddy current to form, what prevent that regulus and other foreign material are involved in strand contains liquid outlet skimming device tundish.
The present invention is for solving the problems of the technologies described above; Following technical scheme is provided: a kind of liquid outlet skimming device tundish that contains; Comprise inclusion, the inlet of inclusion upper end, the liquid outlet of inclusion lower end; It is characterized in that the liquid outlet top is covered with skimming device, described skimming device is conical hollow matrix, and the hollow matrix surface of described taper shape evenly offers several through holes.
As of the present invention preferred, the through hole that matrix surface is offered is a strip, and through this kind setting, molten steel gets into liquid outlet through the strip through hole, thereby avoids producing eddy current, prevents that regulus and other foreign material are involved in strand, improve the quality of products.
For better explaining technical scheme of the present invention; Below introduce operation principle of the present invention in detail: in the casting process; Molten steel in the tundish through behind the filtering-depositing, filters through the through hole obstruct on skimming device surface in tundish, flows into liquid outlet; Slow down molten steel flow speed greatly, thereby effectively reduced the formation of liquid outlet whirlpool.
Beneficial effect of the present invention: the present invention effectively prevents to produce eddy current through above liquid outlet, being covered with skimming device, and the degree of purity of molten steel is provided, and improves the quality of products.
