Description
Technical field
The present invention relates to hot investment casting alloys to melt note field, a kind of high temperature resistant composite crucible is especially provided, as casting
When melt molten metal carrying, play the role of crucible assembly.
Background technique
During alloy melting, the crucible assembly of traditional crucible sleeve method production uses quartz sand as filling branch
Timbering material, sand grains is easily detached from original position after tilting repeatedly, and enters shell so as to cause casting slag inclusion.And due to quartz
Sand filled layer is relatively thin, once crucible liner cracking is run away, molten metal often penetrates quartz sand and is attached to outer lining, at this moment must be whole
Body replacement, influences production efficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of high temperature resistant composite crucibles, can the effective solution above problem.
The technical scheme is that a kind of high temperature resistant composite crucible, comprising: liner 1, rib 2 and outer lining 3；It is described
Outer lining 3 is the tubular structure bottom of with, and the 3 inner wall bottom surface of outer lining is spherical surface, and 3 inner wall of outer lining, which is equipped with the bottom centre of sphere, is
The multiple groups rib 2 that starting point inward wall upper edge extends circumferentially is equidistantly spaced between the multiple groups rib 2, the multiple groups muscle
Item 2 and outer lining 3 are integrally formed, and every group of rib 2 is made of multiple interruption ribs arrangement straggly, and the rib 2 positioned at bottom is arc-shaped；
The liner 1 is set to 3 inside of outer lining and cooperates with multiple groups rib 2.
Preferably, 3 overall diameter of outer lining is 186mm, wall thickness 5mm, a height of 260mm；3 inner wall of outer lining is equipped with
10 groups of ribs 2,2 width of rib is circumferentially 15 °, with a thickness of 8mm.
Preferably, the liner 1 is alumina crucible, outer diameter 160mm.
The compound crucible of the present invention uses 2 structural support liner 1 of rib.Rib 2 is structure as a whole with outer lining 3, can not only
Back-up sand is played to the barrier action of molten metal, and the replacement of liner 1 is extremely convenient, the gap between rib 2 can also accommodate a large amount of races
Fire material, and it is easy to clean.
In use, outer lining 3 need to be only put into furnace skin, then liner 1 is put into, in case of liner 1 and 3 gap of outer lining are larger
The case where, it asbestos cord etc. can be used to stopper, prevent crucible from shaking.
The present invention uses aluminium oxide ceramics integral manufacturing, and coefficient of thermal expansion is consistent, high temperature resistant, once runout situation occurs, only
Liner 1 need to be taken out, after metal charge cleaning remaining in outer lining rib 2, being put into new liner 1 can continue to produce, and greatly improve
Production efficiency.
The present invention has following beneficial effect:
Present invention can apply to various vacuum drying ovens, use it as the container of fusing molten metal, substitution originally make by set
Crucible assembly.With no sand leakage slag inclusion hidden danger, liner replacement is convenient, overall weight is light, equipment loss is small, intensity of packing
The advantages that high, structure is carefully real, choked flow ability is strong, easy to clean is expected in reusable, easy to change, runout.High reliablity, before
Scape is extensive, and it is obvious to reduce slag inclusion effect, while can reduce operator's labor intensity, improve production efficiency, save production cost.
The present invention can effectively eliminate crucible sleeve bring slag inclusion hidden danger, and replacement when crucible runout occurs and conveniently, mentions
High equipment movable rate.Economic benefit estimation: can reduce equipment failure rate 20% every year, reduce casting slag inclusion 60-70%, save more
Change 5 Wan Yuyuan of time cost of crucible.

Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figures 1 to 6, a kind of high temperature resistant composite crucible, comprising: liner 1, rib 2 and outer lining 3.Outer lining 3 is band bottom
Tubular structure, 3 inner wall bottom surface of outer lining be spherical surface, 3 inner wall of outer lining be equipped with prolongs by starting point inward wall upper edge of the bottom centre of sphere
It is circumferentially equidistantly spaced between the 10 groups of ribs stretched, 2,10 groups of ribs 2,10 groups of ribs 2 and outer lining 3 are integrally formed, every group of rib
2 are made of multiple interruption ribs arrangement straggly.3 overall diameter of outer lining is 186mm, wall thickness 5mm, a height of 260mm；10 groups of ribs 2
Width is circumferentially 15 °, with a thickness of 8mm；Rib 2 positioned at bottom is arc-shaped, for matching shape and the carrying of crucible liner 1
Its weight.Liner 1 is set to 3 inside of outer lining and cooperates with 10 groups of ribs 2, and liner 1 is the alumina crucible of unified purchase, and outer diameter is
160mm。
Liner 1 plays the role of containing molten metal；The effect of outer lining 3 is package liner 1 and contains the outer of the runout generation of liner 1
Overflow metal charge, prevents damage equipment；Rib 2 plays the role of supporting liner, while the gap between rib 2 can carry outside more
Overflow metal charge, and is convenient to clean.Outer lining 3 is structure as a whole with rib 2, can not only play back-up sand to the barrier action of molten metal,
And cleaning is convenient, and liner 1 is easy to change.
The compound crucible of the present invention is made of high temperature ceramic material, prepares ceramic model using particular manufacturing craft first,
Then use intensity is reached using sintering furnace sintering and using temperature, that is, can be applied in vacuum drying oven.
The compound crucible of the present invention is compared and analyzed with existing crucible assembly below:
Crucible assembly used in actual production is outer lining, back-up sand, liner 3-tier architecture at present, is made among outer lining and liner
It is stoppered after being filled with quartz sand with asbestos cord, and is blocked with slurry, operation is more complex, and quartz sand easily enters once loosening
Shell causes casting slag inclusion.Once and crucible is run away, it is necessary to integral replacing, it is time-consuming and laborious.
The compound crucible of the present invention is divided into liner 1, rib 2,3 three layers of outer lining, and rib 2 is structure as a whole with outer lining 3.Liner
1 dimensionally matches with rib 2, can directly be put on rib 2, such as liner 1 and the larger situation in 3 gap of outer lining, can make
It is stoppered with asbestos cord etc., prevents crucible from shaking.Entire composite crucible does not use quartz sand, and just there is no sand leakage brings to press from both sides naturally
Slag hidden danger.Once crucible runout occurs, liner 1 need to only be taken out, the runout material between rib 2 is removed, is reloaded into new liner 1 i.e.
It can continue to produce, greatly improve efficiency.
The present invention achieves many things at one stroke, and is widely used, and the alloy suitable for most of vacuum drying oven is poured, and has application prospect wide
General, high reliablity saves time cost, the advantages that Improving The Quality of Products.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
