Description
Technical field
The utility model relates to a kind of closing device, especially a kind of tundish, which is opened, pours closing device, belongs to metallurgical continuous casting
Field.
Background technique
In the technological process of production of continuous casting, it will be transported to revolving platform equipped with the ladle for having refined molten steel, opened to tundish to pouring
After casting position, revolving platform is turned to tundish position directly above, molten steel is injected into tundish, tundish is again by the mouth of a river by molten steel
It is assigned in each crystallizer.
During ladle molten steel enters tundish, needs each mouth of a river for shunting tundish to block, wait tundish
After liquid steel level reaches 400mm or more, then each shunting mouth of a river opened, allows molten steel to enter crystallizer, one side can be in this way
Guarantee pouring basket liquid level pressure, shunt after the mouth of a river is opened beam will not bifurcated, guarantee after the cold burden fusing in crystallizer with draw it is fixed
Stick sufficiently bonds together, and avoids pulling or bleedout；It on the other hand can uniformly liquid steel temperature and ingredient, it is ensured that field trash has foot
The enough time floats, and plays the role of purifying molten steel.
Have the following problems however, closure mode is poured in traditional opening: (1) object is more, plugging operations are cumbersome: object respectively divides
From needing that successively bracket, stifled cone, sash weight are placed in below tundish when blocking intermediate package operation, be not easy to operate.(2) it hangs
Hammer and stifled cone are easy to fall off, and are caused to open and are poured failure: since ladle nozzle is opened moment, steel stream to tundish can generate impact or
With the increase of Metal Weight in middle packet, middle hired car can generate certain aftershock after being pressurized, and be easy to make to be blocked in middle water containing opening
Interior stifled cone falls off, and causes the molten steel in middle packet also not up to open the condition of pouring and enters crystallizer in advance, at this time steel in tundish
Water level is low, pressure is small, temperature is low, causes beam is soft to dissipate, molten steel cannot lead to the cold burden in crystallizer completely into crystallizer
It is bonded together after cannot melting well with dummy ingot stick, be easy to cause and pull or bleedout, or even copper pipe is caused to scratch or equipment
Damage, increases the labor intensity of worker and opens and pour cost.(3) open casting operation is cumbersome, there are security risks: needing when open casting operation
Successively to withdraw sash weight, stifled cone, bracket, sash weight is easy to fall off when operation, injures operator by a crashing object.
Utility model content
In order to solve the above-mentioned technical problem, the utility model, which provides a kind of tundish and opens, pours closing device, the utility model
Concrete scheme it is as follows:
A kind of tundish, which is opened, pours closing device, it is characterised in that: the sizing water including tundish, on tundish pedestal
Mouth, the folder on tundish pedestal and the body of rod connecting with folder, body of rod one end are equipped with clump weight, and the other end is equipped with stifled
Cone, clump weight drive the body of rod using the interconnecting piece of the body of rod and folder as support motion, and the body of rod drives stifled cone blocking to live sizing nozzle.
Further, sizing nozzle is in T font, is equipped with tundish upper nozzle in sizing nozzle, is blocked up on cone insertion tundish
Mouth of a river bottom.
Further, the clump weight is metal cylinder.
Further, folder and the body of rod are equipped with nut, are connected between folder and the body of rod by metal wire.
Further, folder is along tundish base motions.
Further, cone insertion tundish upper nozzle bottom is blocked up, the tundish upper nozzle for blocking up cone top is filled stuffing sand, prevented
Only molten steel and stifled tapered joint touch.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1), the utility model utilizes bar thick stick principle, and plugging operations and open casting operation are easy.Stifled cone can be positioned firmly
In the mouth of a river of tundish, avoids opening caused by impacting or vibrate because of steel stream and pour failure, raising, which is opened, pours success rate.
(2), labor intensity of operating staff is reduced, security risk is eliminated.Reduce rejection number, reduces to open and pour into
This.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, the technical solution in the present embodiment is carried out it is clear, complete
Site preparation description, it is clear that described embodiment is only the example to a part of example of the utility model, rather than whole.Base
In the embodiments of the present invention, those of ordinary skill in the art institute obtained under that premise of not paying creative labor
There are other embodiments, fall within the protection scope of the utility model.
As shown in Figure 1, the tundish of the present embodiment, which is opened, pours closing device, including tundish 1, it is set on tundish pedestal 3
Sizing nozzle 4, the folder 6 on tundish pedestal 3 and the body of rod 8 being connect with folder 6,8 one end of the body of rod be equipped with round metal
Cylinder 9, the other end are equipped with stifled cone 7, and folder 6 and the body of rod 8 are equipped with nut, are connected between folder 6 and the body of rod 8 by metal wire,
Metal cylinder 9 drives the body of rod 8 using the nut of the body of rod 8 as support motion, and the body of rod 8 drives stifled cone blocking 7 to live sizing nozzle 4.Folder 6
It is moved along tundish pedestal 3.The present embodiment replaces sash weight with the suitable metal cylinder of weight, and cylindrical body is welded on stifled cone
The tail portion of bar.
Sizing nozzle 4 is in T font, is equipped with tundish upper nozzle 5 in sizing nozzle 4, blocks up 7 insertion tundish upper nozzle 5 of cone
Bottom.After insertion, the tundish upper nozzle 5 for blocking up 7 top of cone fills stuffing sand, prevents molten steel 2 from contacting with stifled cone 7.
Folder can be made in the present embodiment of the round tube of opening appropriateness, and folder and stifled cone bar are respectively welded nut, use metal
Folder is fastened the suitable position in stifled cone bar by line, and metal cylinder, the body of rod, stifled cone, folder are connected into an entirety, when operation
Folder is clipped in the middle on the pedestal of packet, the whole operation of mouth of a river closure can be completed, open and remove folder when pouring.
Tundish is opened when pouring plugging operations, and folder is clipped in the middle on packet pedestal, the body of rod, stifled cone and metal cylinder
It hangs on immediately below sizing nozzle of tundish, using lever principle, is blocked stifled cone by folder using metal cylinder self weight
Inside the sizing nozzle, then the filling pipe end that respectively flows from tundish is respectively put into the stuffing sand of 0.5kg, prevents molten steel and stifled tapered joint
Touching, when Metal in Tundish liquid level reaches 400mm or more, folder is removed from pedestal, under the action of ferrostatic pressure (or
Pass through oxygen Tube Drain), molten steel can enter crystallizer by sizing nozzle, smoothly complete the open casting operation of tundish.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
