Abstract
The invention belongs to the field of cast melt containers and particularly discloses an anti-overflowing continuous-casting tundish. The anti-overflowing continuous-casting tundish comprises a tundish body and further comprises a baffle, a rotary rod, a floating block, a supporting rod and a slide. An overflow opening is formed in the side wall of the tundish body. The supporting rod is fixed to the inner wall of the tundish body. The rotary rod is hinged to the supporting rod. The baffle is hinged to one end of the rotary rod. The floating block is fixed to the other end of the rotary rod. The overflow opening can be closed through the baffle. The slide is obliquely arranged. The high end of the slide is fixed to the tundish body. The slide is located under the baffle. Compared with a traditional continuous-casting tundish, the anti-overflowing continuous-casting tundish has the advantages that the overflow opening can be opened automatically by means of the buoyancy force of the floating block and the lever principle when the amount of molten steel is overlarge, manual attendance is not needed, the molten steel is effectively prevented from overflowing from a liquid inlet of the tundish, and safety accidents are reduced.
Description
Technical field
The invention belongs to casting fused mass field of containers, particularly relate to a kind of continuous casting production preventing overflowing.
Background technology
Continuous casting production is important metallurgical technology equipment, it is not only distribution, ensures the buffer of molten steel direct casting, it is still removed non-metallic inclusion, evenly liquid steel temperature, prevents slag from entering the key equipment of the guarantee slab qualities such as crystallizer, and its metallurgical effect directly affects the quality of strand.Molten steel enters in tundish from the inlet of tundish, and then flow in crystallizer from the liquid outlet of tundish pass in and out next step operation, thus realize continuously operate.And in actual mechanical process, need the amount in strict control inflow tundish.When the equipment controlling molten steel flow breaks down, then the amount in tundish may be caused too much, and molten steel overflows from the inlet of tundish, causes security incident.
So, be badly in need of a kind of when controlling the equipment of molten steel flow and breaking down, the device that molten steel overflows from the inlet of tundish can be avoided.
Summary of the invention
Object of the present invention is providing a kind of continuous casting production preventing overflowing.
In order to achieve the above object, base case of the present invention is: can prevent the continuous casting production overflowed, comprise tundish body, wherein, also comprise baffle plate, dwang, floating block, pole and slide, the sidewall of described tundish body is provided with overfall, described pole is fixed on the inwall of tundish body, described dwang is hinged on the middle part of pole, panel hinge is in one end of dwang, floating block is fixed on the other end of dwang, described baffle plate can close overfall, described slide is obliquely installed, it is high-end is fixed on intermediate plate body, and slide is positioned at immediately below baffle plate.
The principle of this base case is: when the equipment controlling molten steel flow breaks down, when the amount of the intrinsic molten steel of tundish increases, then illustrate that molten steel is excessive.Now, molten steel contacts with floating block, and because floating block has certain buoyancy, the amount of molten steel continues to increase, and impel dwang to rotate, baffle plate moves, then overfall is in open mode, and molten steel then can flow into slide from overfall and be transported to other places and reclaim.
The beneficial effect of this base case is: baffle plate can block overfall, avoids air to enter in tundish, makes the state that tundish body remains airtight, reduces the thermal loss in tundish.Compared with traditional continuous casting production, when molten steel is excessive, this programme utilizes buoyancy and the lever principle of floating block, then can automatically realize automatically opening of overfall, without the need to artificial guard, effectively avoid molten steel and overflow from the inlet of tundish, decrease the generation of security incident.
Scheme two: based on this, scheme is preferred, the hinge of described dwang and pole near baffle plate away from floating block.According to lever principle, floating block can make baffle plate move being subject to less power, the effective volume reducing floating block.
Scheme three: this is the preferred of scheme two, described floating block is the Refractory blocks being provided with cavity.The design of cavity effectively adds the buoyancy of Refractory blocks.
Scheme four: based on this, scheme is preferred, described baffle plate is silica fire resistant baffle plate, and described dwang and pole are silica fire resistant bar.Because the intrinsic temperature of tundish is higher, baffle plate, pole and dwang that silica refractory is made have good high temperature resistant and acid-resistant corrosion, high life.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention can prevent the continuous casting production embodiment of overflowing.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: tundish body 10, inlet 11, liquid outlet 12, baffle plate 20, pole 21, dwang 22, floating block 23, slide 30.
As shown in Figure 1, the continuous casting production overflowed can be prevented, comprise tundish body 10, baffle plate 20, dwang 22, floating block 23, pole 21 and slide 30.The top of tundish body 10 is processed with inlet 11, and bottom is processed with liquid outlet 12.In addition, the sidewall of tundish body is provided with overfall.Pole 21 is welded on the inwall of tundish body 10, dwang 22 passes through high temperature resistant pin-hinges on pole 21, baffle plate 20 passes through high temperature resistant pin-hinges in 22 upper ends of dwang, cavity is provided with in floating block 23, floating block 23 is welded on the lower end of dwang 22, the size of baffle plate 20 is greater than the aperture of overfall, and when floating block 23 is not by buoyancy, then baffle plate 20 can close overfall.Slide 30 is obliquely installed, and it is high-end is welded on intermediate plate body 10, and slide 30 is positioned at immediately below baffle plate 20.Baffle plate, pole, floating block and dwang are made by silica refractory, have good high temperature resistant and acid-resistant corrosion, high life.
During specific works, when the equipment controlling molten steel flow breaks down, when the amount of the molten steel in tundish body 10 increases, then illustrate that molten steel is excessive.Now, molten steel contacts with floating block 23, because floating block 23 has certain buoyancy, the amount of molten steel continues to increase, then impel dwang 22 to rotate clockwise, 20, baffle plate moves down, then overfall is in open mode, and molten steel then can flow into slide 30 from overfall and be transported to other places and reclaim.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
