Abstract
The invention discloses a tundish with a pouring box body and belongs to the technical field of vacuum ingot pouring. The tundish body is circular; a tundish water port is formed at the bottom of the tundish; and the pouring box body is arranged on one side of the tundish. The pouring box body is built by a first special brick, a second special brick and a third special brick; a pouring channel is formed in the middle of the pouring box body; a molten steel outlet is formed at the bottom of the pouring box body; a steel flowing hole is formed in the middle of the pouring box body; a guiding dam is formed at the front end of the molten steel outlet at the bottom of the tundish body; and a steel discharge hole is formed on one side of the guide dam. The pouring channel is formed inside the pouring box; liquid steel flows into the tundish from the bottom of the pouring channel so as to prevent the molten steel from back flowing on the surface in the tundish, the obviously turbulent part of the liquid steel is centralized on the steel pouring side and a steadily flowing molten bath is formed in the tundish. The guiding dam can block the flow of the molten steel along the bottom of the tundish, the flowing direction turns upward, the flow of the liquid steel of the tundish is improved, liquid level fluctuation in the tundish is reduced, the slag entrapment probability is reduced, the residence time of the liquid steel in the tundish is increased, the flotation of impurities is accelerated, a reasonable temperature distribution field is formed, and the inner quality of a steel ingot is improved.
Description
Technical field
the present invention relates to a kind of tundish of Strip casting casing, belong to vacuum-casting casting technique field.
Background technology
When
existing tundish waters molten steel; Flowing of molten steel produces disturbance to liquid steel level in wrapping; Slag in the formation of the surface of molten steel can be impacted darker position below the entering liquid level by molten steel, particularly get into the flow field that forms when the inner slag of molten steel is poured into a mould by middle water containing opening and bring ingot mould generation volume slag into; Owing to when the basket pouring molten steel, impact the molten steel surface, make the interior molten steel of tundish not carry out the liquid level protection with coverture or covering slag, cause the molten steel secondary oxidation serious; Molten steel time of staying in tundish is short, and Temperature Distribution is unreasonable, and the field trash in the molten steel is prone to brought in the ingot mould by molten steel through watering the steel inlet, influences product quality.
Summary of the invention
are in order to overcome above-mentioned technical deficiency; The object of the present invention is to provide a kind of tundish of Strip casting casing, this tundish can not only reduce liquid level fluctuation of molten steel in the tundish, reduces volume slag probability; Increase molten steel time of staying in tundish; And can promote inclusion floating, and form comparatively rational temperature distribution field, improve the internal soundness of steel ingot.
the technical solution adopted for the present invention to solve the technical problems is: inclusion is for circular, and its bottom is provided with middle water containing opening, and the one of which side is provided with the cast casing; The cast casing is built by laying bricks or stones and is processed by special shaped brick one, special shaped brick two, special shaped brick three; Be provided with the cast passage in the middle of the cast casing, the bottom is provided with molten steel outlet, and the middle part is provided with steel outlet hole; Be provided with training dyke at inclusion bottom steel water out front end, training dyke one side is provided with steel discharging hole.
cast casing can also be built by laying bricks or stones and processed by special shaped brick one, special shaped brick three, is provided with the cast passage in the middle of the cast casing, and the bottom is provided with molten steel outlet.
The structure of each special shaped brick is:
It is shaped as rectangle
special shaped brick one, and the both sides front end is to inner bevel relatively, and the centre is provided with the cast passage.
It is shaped as rectangle
special shaped brick two, and the both sides front end be to inner bevel relatively, and the centre is provided with the cast passage, and its front end is provided with steel outlet hole and pours into a mould passage and communicate.
It is shaped as rectangle
special shaped brick three, and the both sides front end is to inner bevel relatively, and its front end is provided with the channel-section steel water out, and channel-section steel water out inside is provided with straight flange and the hypotenuse parallel with special shaped brick three ground.
the invention has the beneficial effects as follows: be provided with the cast passage in the pouring box; Molten steel flows in the tundish from the bottom of cast passage; Prevent that effectively molten steel surface refluxes in the tundish; And make significant partly the concentrating on of molten steel turbulence water the steel side, form the molten bath comparatively stably of flowing in the tundish; Training dyke can stop along wrapping flowing of the end, makes mobile directional steering top.Improve flowing of tundish molten steel, reduce liquid fluctuating in the tundish, reduce volume slag probability, increase molten steel time of staying in tundish, promote inclusion floating, form the rational temperature distribution field.
and; Also possesses the refining effect of further cleaning molten steel: after molten steel enters into tundish via cast channel bottom molten steel outlet; Molten steel is moved to top by the tundish bottom under the effect of training dyke; The field trash of bringing into the floating upward quickly that can move upward makes molten steel pure.
