Description
Technical field
The utility model relates to mold casting technique field, especially a kind of sealed feed trumpet.
Background technique
Casting bet steel ingot, generallys use the combination mode structure of feed trumpet, chassis, ingot mould, wherein feed trumpet is adopted at present
With structure integrated or separately, shape is essentially down big up small.Feed trumpet includes tube body (shell), and tube body is mostly by iron casting
It forms, casting channel, the funnel brick that casting vias inner walls are equipped with injecting pipe brick and connect with injecting pipe brick, funnel brick position is equipped in tube body
It is suitable for reading in casting channel, and funnel brick is suitable for reading need to be higher by 50~l00mm of tube body.When casting, ladle nozzle right above funnel brick,
Mouth of a river steel stream is opened just to enter in feed trumpet.
In actual operation due to can not achieve contact sealed cast between ladle and funnel brick, molten steel is from ladle injection
During infusing pipe, pouring beam can be aoxidized by air secondary, to reduce the degree of purity of molten steel, be unfavorable for producing high quality
Bet steel ingot.For steel stream by into oxidation, existing usual way is that guard circle is arranged on feed trumpet in casting process in order to prevent,
It is provided with uniformly distributed gas vent on guard circle, is passed through argon gas to guard circle in ingot steel casting, makes guard circle in ladle and middle note
An annular air curtain curtain is formed between pipe, but since the air curtain curtain uniformity sprayed through gas vent is bad, and air curtain curtain is easy
It is influenced by natural wind, protecting effect is not ideal enough.
Utility model content
The technical problem to be solved by the utility model is to provide one kind, and the sealed of casting can be sealed with ladle
Feed trumpet.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of sealed feed trumpet, including tube body,
It is equipped in the tube body and is poured channel, the funnel brick that the casting vias inner walls are equipped with injecting pipe brick and connect with the injecting pipe brick,
The funnel brick is located at that the casting channel is suitable for reading, the tube body be equipped with its be tightly connected and be higher than the funnel brick it is close
Tube sealing, the seal pipe upper surface are provided with sealing ring, and the seal pipe is additionally provided at least two ventholes.
Further, the seal pipe upper surface is equipped with the groove of annular, and the sealing ring is inlayed in the groove.
Further, the seal pipe side is additionally provided with peep-hole, and the peep-hole is equipped with transparent sealing cover.
Further, the venthole is circumscribed with quick coupling.
Further, the seal pipe and the tube body are separate structure.
The beneficial effects of the utility model are: a kind of sealed feed trumpet of the utility model, seal pipe is set on tube body,
When being poured steel ingot, sealing is contacted with ladle by the sealing ring in seal pipe, so as to completely cut off air and steel pouring stream completely
Without being influenced by the external world, therefore when casting steel ingot, sealing effect is more preferable for contact, it is ensured that the degree of purity of steel quality, raising are poured
Infuse ingot quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the casting schematic diagram of the utility model；
It is as shown in the figure: 1. tube bodies, 2. casting channels, 3. injecting pipe bricks, 4. funnel bricks, 5. seal pipes, 6. ladles, 51. sealings
Circle, 52. ventholes, 53. peep-holes, 54. sealing covers, 55. quick couplings.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of sealed feed trumpet of the utility model, including tube body 1, the tube body 1 is interior to be equipped with casting
Channel 2, the funnel brick 4 that casting 2 inner wall of channel is equipped with injecting pipe brick 3 and connects with the injecting pipe brick 3, the funnel brick 4
It is suitable for reading in the casting channel 2, the tube body 1 be equipped with its be tightly connected and be higher than the funnel brick 4 seal pipe 5, institute
It states 5 upper surface of seal pipe and is provided with sealing ring 51, the seal pipe 5 is additionally provided at least two ventholes 52.
Tube body 1 is equipped with the seal pipe 5 higher than funnel brick 4, i.e. the upper tube of seal pipe 5 when on tube body 1 is arranged in seal pipe 5
Mouth need to be higher by the suitable for reading of funnel brick 4, to can be placed in ladle 6 in seal pipe 5 when being poured without contacting with funnel brick 4.It is close
Tube sealing 5 is equipped at least two ventholes 52, and one can be used as air inlet, another can be used as gas outlet.In Fig. 1, two ventilations
Hole 52 is symmetricly set on the two sides of seal pipe 5.
Specific casting process as shown in Fig. 2, when ingot steel casting, by ladle 6 hang in seal pipe 5, make 6 bottom surface of ladle with
Sealing ring 51 on 5 upper surface of seal pipe carries out contact sealing, while hanging ladle 6 with crane to undertake moiety by weight, so as to
6 held stationary of ladle, safety；Again by being passed through protective gas (argon gas) to the venthole 52 as air inlet to displace casting
Air in channel 2, time swap about 5-30min；After the completion of displacement, the mouth of a river for opening ladle 6 is poured.Due to casting
When, ladle bottom surface is to contact sealing with the sealing ring in seal pipe, so as to completely cut off completely air contacted with steel pouring stream and
Sealing effect is more preferable when not influenced by the external world, therefore being poured steel ingot, it is ensured that the degree of purity of steel quality improves casting steel ingot
Quality.
As shown in Figure 1,5 upper surface of seal pipe is equipped with the groove of annular, sealing ring is set by the mode being embedded in groove
It sets on 5 upper surface of seal pipe, can also directly be bonded on 5 upper surface of seal pipe certainly, but this mode, sealing ring hold below
Easily fall.
It is poured situation for the ease of observation, 5 side of seal pipe is additionally provided with peep-hole 53, and peep-hole 53 is equipped with transparent sealing
Lid 54.Peep-hole 53 can be one or more, preferably 2 and be symmetricly set on 5 two sides of seal pipe.
For the ease of connecting with tracheae, venthole 52 is circumscribed with quick coupling 55.
5 material of seal pipe can be for cast iron or iron etc., and seal pipe 5 can be by being clamped, being bolted or directly the modes such as place
It is set on feed trumpet tube body 1, i.e., the two is separate structure, can be also structure as a whole certainly.Preferably, seal pipe 5 with
Tube body 1 is separate structure, so as to the lifting of feed trumpet.When seal pipe 5 and tube body 1 are separate structure, seal pipe 5 can be with tube body 1
Mounting, both seal pipe 5 and tube body 1 can be directly sealed by the contact surface of the two, certainly can also be in the contact surface of the two
Upper setting sealing structure in figure is sealed by the contact surface of the two.
