Abstract
The invention discloses a kind of fence type melting kettle, including the fence of crucible body and circular tube shaped, the lower end matching of the fence is extend into the port of the crucible body, and more cross bar legs are also welded with the fence lower sides；The cross bar leg is supported on the port of crucible body, and the end of cross bar leg is bolted and is installed with an annular support；Sprue gate is provided with the port of the crucible body, the lower end of the fence is being provided with opening at sprue gate, and the breach corresponding to the sprue gate also is provided with the annular support.The present invention reduces the dosage of crucible material, the operation such as charging, cleaning clinker when the Fence structure of setting facilitates melting, and it is practical, it is worthy to be popularized.
Description
Technical field
The present invention relates to a kind of fence type melting kettle.
Background technology
At present, sintered NdFeB temperature in melting reaches 1450-1500 DEG C, it is therefore desirable to which crucible being capable of high temperature resistant, length
Life-span, low cost, generally use alumina crucible.During shove charge, raw material are more slightly higher than mouth of pot, after raw material fusing, molten steel position
In crucible bottom, so often causing crucible bottom to be easier loss, cracking, disrepair phenomenon occur, so as to cause whole earthenware
Crucible is scrapped.Crucible of the prior art, it is cylindrical crucible structure, is scrapped once crucible bottom damage will result in entirety, from
And increase production cost.By taking crucibles of the 600kg per stove as an example, its depth is about 800mm, is unfavorable for mending crucible operation.And due to
Crucible limited height, raw material can be higher than mouth of pot during charging, the raw material at mouth of pot in fusion process constantly fusing,
Decline, may be crowded together and arch formation occur, cause device damage, raw material the major accident such as to scrap when serious.
Chinese invention patent（201110271771.0）" a kind of composite crucible for growth of sapphire crystals " discloses one kind
Composite crucible, it is made up of Crucible body and lengthening crucible tube, Crucible body and lengthening crucible tube are connect by location fit surface cover.Should
The wall thickness of crucible tube is lengthened in invention such as Crucible body, it is heavier, it is not easy to dismantle, only when Crucible body is damaged
Just pull down.
The content of the invention
The present invention is in order to solve the above-mentioned deficiency of prior art, it is proposed that a kind of fence type melting kettle.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of fence type melting kettle, including earthenware
The fence of crucible body and circular tube shaped, the lower end matching of the fence are extend into the port of the crucible body, and under the fence
More cross bar legs are also welded with portion's side wall；The cross bar leg is supported on the port of crucible body, and cross bar leg
End is mounted by means of bolts on an annular support；Sprue gate is provided with the port of the crucible body, it is described to enclose
The lower end on column is being provided with opening at sprue gate, and lacking corresponding to the sprue gate also is provided with the annular support
Mouthful.
Further, described crucible body is cylindrical, and the internal depth of crucible body is 650mm, and wall thickness is 20~
35mm。
Further, the use stainless steel of described fence is made, and the fence height is 300mm, wall thickness 1.0mm.
Compared with prior art, it is an advantage of the invention that：The crucible material dosage is few, about the 85% of conventional crucible, can
Save crucible manufacturing cost.Crucible depth only has the 75~85% of conventional crucible, and hand can be easily deep into earthenware by operator
Crucible bottom mend crucible operation, the timely good repairing of crucible extends its service life, about conventional crucible service life
1.5~2 times, reduce the use cost of crucible.In fusion process, molten steel is located inside the crucible of stainless steel, the bottom of fence
At a distance of 100~200mm, the temperature of fence is far below the temperature of molten steel for portion and liquid steel level, but due to fence have it is corrosion-resistant, resistance to
The characteristics of high temperature, it ensure that fence, still in solid-state, has the characteristics of durable in use in fusion process.In addition, crucible adds
The total height of fence is more than the height of conventional crucible, easily charging, can avoid building bridge now to the utmost in fusion process
As may caused by device damage, raw material the major accident such as scrap.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Invention is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, fence type melting kettle proposed by the present invention, including the fence 2 of crucible body 1 and circular tube shaped, enclose
The lower end matching on column is extend into 1 port of crucible body, and is also welded with more cross bar legs 3 on the lower sides of fence 2；
Cross bar leg 3 is supported on the port of crucible body 1, and the end of cross bar leg 3 is mounted by means of bolts on a ring-type
On support 4；Sprue gate 11 is provided with the port of crucible body 1, the lower end of fence 2 is being provided with opening at sprue gate 11
21, and the breach corresponding to sprue gate 11 also is provided with the annular support.Crucible body 1 is cylindrical, and crucible body
Internal depth is 650mm, wall thickness 25mm.Fence 2 is made of stainless steel, and the fence height is 300mm, and wall thickness is
1.0mm.The external diameter of fence 2 is more smaller than the internal diameter of crucible body 1, can be put into crucible body, and easily can be taken out of crucible body
Go out.
In actual production, after melting terminates, fence 2 is first removed, removing slag simultaneously repairs crucible body 1, is loaded on one
Part raw material, then fence 2 is fixed on annular support 4, finally loaded remaining raw material in fence 2.Using this
After kind structure, it is easy to mend crucible operation, extends the service life of crucible body 1, so as to save the use cost of crucible body,
The height of fence 2 is enough, facilitates charging operation, and also avoiding arch formation to the utmost in fusion process may cause
Device damage, raw material the major accident such as scrap.
Above-described embodiment only expresses the several embodiments of the present invention, and its description is more specific and detailed, but can not
Therefore understands that it is the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
On the premise of not departing from present inventive concept, various modifications and improvements can be made, these belong to protection scope of the present invention.
Therefore, patent of the present invention and protection domain should be defined by appended claims.
