Abstract
The utility model relates to a tundish turbulator which comprises a body (1). The body (1) is cubic and is provided with an open hollow inner chamber. The hollow inner chamber comprises an opening part (3) and a chamber part (4) which is arranged below the opening part (3) and is communicated with the opening part (3). The tundish turbulator is characterized in that the opening part (3) and the chamber part (4) are of circular or elliptical cylindrical cavities, and the two cylindrical cavities of the opening part (3) and the chamber part (4) are transitioned to each other through a smooth transitional part. Since anti-splashing lines can reduce the impact force of molten steel which flows into the tundish turbulator, the situations that the upper part and the right-angle corner part of the turbulator are cracked because of molten steel vortexes can be reduced, the molten steel flowing direction is enabled to be reasonable, the situation that the molten steel is splashed can be effectively avoided, the molten steel is enabled to flow in order, the consumption of the turbulator can be reduced and the service life of a tundish can be prolonged.
Description
Technical field
The utility model relates to metallurgical technology field, particularly a kind of tundish turbulator.
Background technology
Important key equipment of high efficiency continuous casting technology that the continuous casting tundish generally adopts as current international steel industry plays an important role to stabilizing continuous casting production and raising continuous casting billet quality.
Continuous casting injects the process of tundish at molten steel, molten steel flow is rapid and not steady in the tundish, cinder inclusion is involved in molten steel, molten steel secondary oxidation in the middle of can causing, it flows and is made up of three parts, that is: piston flow, complete mixing flow and stagnant area (dead band), wherein piston flow and complete mixing flow are referred to as the region of activation, wherein, the molten steel stagnant area accounts for the 30-50% of whole tundish volume, the molten steel mixed effect is relatively poor in the tundish, is unfavorable for stablize the molten steel supply, satisfies the realization that molten steel composition and temperature evenly, effectively promote function such as field trash eliminating; Simultaneously, in casting process, the molten steel in the ladle constantly flows in the tundish, since the kinetic energy effect of molten steel, the MOLTEN STEEL FLOW rather unstable in ladle nozzle zone, and slag often is involved in the molten steel, causes continuous casting billet internal soundness defective.For addressing the above problem, generally use the tundish turbulator.
But tundish turbulator of the prior art has low shortcoming in service life, and in use be subject to high-temperature molten steel wash away erosion generally between 20-36 hour its service life, thereby causes turbulator broken and floating phenomenon takes place; In addition,, worn the bag accident, cause damage equipment, influence to be produced thereby the bottom of turbulator penetrates to cause easily using the later stage.
Summary of the invention
Cause the tundish turbulator of wearing the bag accident thereby the purpose of this utility model provides and is not subject to the molten steel scouring erosion in a kind of long service life, the use, use the later stage bottom to be difficult for penetrating.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of tundish turbulator, comprise body, and described body is cube shaped; Described body has uncovered hollow lumen, and described hollow lumen comprises the cavity portion that peristome and the below that is positioned at described peristome are communicated with peristome; Described peristome and cavity portion all are circular or oval-shaped cylindrical cavity, and pass through smooth transition part between two cylindrical cavities of described peristome and cavity portion; The bottom of described cavity portion also is provided with water conservancy diversion splashproof line.
Described splashproof line can slow down the impulsive force after molten steel flows into turbulator, thereby reduce molten steel whirlpool caused turbulator top and right angle corner position cracking, make steel flow to rationally, and can prevent effectively that molten steel from splashing, making molten steel to flow in order, therefore can reduce turbulator consumption, prolong tundish service life.
