Abstract
The present invention provides a kind of feed trumpet, including feed trumpet top comprising upper plane, top lifting lug and lower plane, the upper plane are equipped with the pedestal for docking with argon protective device, and the upper plane is horn mouth；Feed trumpet lower part comprising top and lower part lifting lug, the top are equipped with the steel plate for docking with the lower plane on the feed trumpet top.Feed trumpet of the invention is transformed utilization to original feed trumpet, and reduces the manufacture and manufacture difficulty of new feed trumpet, and manufacturing expense is greatly saved.
Description
Technical field
The present invention relates to casting field, especially a kind of feed trumpet.
Background technique
Tooling when feed trumpet is injected when betting ingot steel casting as molten steel, it is desirable that be higher than bet steel ingot (riser suitable for reading
Top) certain distance, to guarantee that casting can be gone on smoothly, traditional feed trumpet is integral type, and length is unique, structure is simple, different
The feed trumpet of height corresponds to different bet steel ingots, and when corresponding large-scale bet steel ingot, feed trumpet height is especially high, and assembly is tired
It is difficult.It and without argon for protecting pouring device, need in addition place, place difficulty, be easy to happen argon protective device drop event.
With the development of bet steel ingot technology, the tonnage for steel ingot of betting is becoming larger, maximum other up to 100 tonnes, therefore under
The height for infusing steel ingot is also higher and higher, and by taking my 54 tonnes of bet steel ingots of company as an example, the requirement for height of feed trumpet is 4.2 meters, and
It almost corresponds with steel ingot (feed trumpet be higher by steel ingot it is too many if it is unfavorable to casting quality).Excessively high feed trumpet is manufacturing
When manufacture difficulty it is larger, in ingot casting, assembly is also inconvenient, and it is trumpet type that traditional feed trumpet is suitable for reading, is unfavorable for argon gas protection dress
The placement set (easily inclination, when casting are easy to touch down).
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of easy to assembly, use simple, safe and reliable and protecting effect
Better feed trumpet.
In order to solve the above technical problems, the present invention provides a kind of feed trumpet, including feed trumpet top comprising it is upper flat
Face, top lifting lug and lower plane, the upper plane are equipped with the pedestal for docking with argon protective device, and the upper plane is
Horn mouth；Feed trumpet lower part comprising top and lower part lifting lug, the top are equipped with for lower flat with the feed trumpet top
The steel plate of face docking.
Preferably, the diameter of the lower plane on the feed trumpet top is equal with the steel plate diameter.
Preferably, the diameter of the lower plane on the feed trumpet top is 700 millimeters.
Preferably, the steel plate thickness is 80 millimeters.
Preferably, the feed trumpet is for producing 54t bet steel ingot.
Preferably, the pedestal is circular ring shape steel plate, with a thickness of 10 millimeters.
Preferably, the feed trumpet material is grey cast-iron.
Preferably, after the pedestal is docked with argon gas pipeline, then ceramic fibre circle is installed.

Specific embodiment
Feed trumpet of the invention be it is split type, be divided into feed trumpet top 10 and feed trumpet lower part 20.It wraps on feed trumpet top 10
Plane 11, top lifting lug 12 and lower plane 13 are included, the upper plane is equipped with the pedestal for docking with argon protective device
14, the upper plane is horn mouth.
Feed trumpet lower part 20 include top 22 and lower part lifting lug 21, the top 22 be equipped with for the feed trumpet top
Lower plane docking steel plate 23.
Feed trumpet lower part 20 is transformed using the feed trumpet of small-sized bet steel ingot, and when transformation, feed trumpet horn mouth position is cut
It goes, welds upper one block of smooth steel plate, for being docked with the upper half feed trumpet.
Feed trumpet material of the invention is grey cast-iron, and upper and lower opening plane need to be processed by precision, and upper port plane welds argon gas
Protective device pedestal (annulus, steel plate thickness 10mm, inner wall spile, hole diameter 2mm), lower half top remove original annotation pipe loudspeaker
Mouthful, weld a steel plate (thickness 80mm) and lifting lug.
Using this tooling, when producing 54t large size bet steel ingot, lower half feed trumpet is transformed using original 13.7t feed trumpet,
One piece of steel plate (thickness 80mm) is welded after former feed trumpet removal horn mouth suitable for reading, as datum level and feed trumpet the upper half pair
It connects, more convenient, feed trumpet prefabricated argon protective device pedestal suitable for reading when assembly, when use only need to be right with it by argon gas pipeline
It connects, is mounted directly ceramic fibre circle, easy to use, securely and reliably, and protecting effect is more preferable than in the past.
Feed trumpet is split type after improvement, and lower half can be used existing feed trumpet and be transformed, the upper half welding
Argon protective device pedestal, without in addition placing.
Feed trumpet of the invention is transformed utilization to original feed trumpet, and reduce new feed trumpet manufacture and
Manufacturing expense is greatly saved in manufacture difficulty.Upper port plane directly welds the pedestal that argon gas guarantees device, installation argon gas protection
Device is very convenient, and protecting effect also greatly promotes, and using effect is good.
