Abstract
The utility model is related to a kind of bottom separate type gas-atomized powder insulation crucible, and the insulation crucible is constituted by crucible body, every liquid funnel and mozzle.The crucible body is threadedly connected with mozzle, described to set crucible body bottom every liquid funnel, is brought into close contact every liquid funnel with crucible body bottom, crucible body every liquid funnel by mozzle with being fixed.Separate type gas-atomized powder in bottom of the present utility model is with insulation crucible, it is crucible body, detachable every liquid funnel and mozzle, after the completion of powder by gas-atomization, it will can be pulled down every liquid funnel with mozzle from crucible body, without apparent damage crucible body, the service life of crucible body is improved, the cost of powder by gas-atomization is reduced.
Description
Technical field
The utility model is related to a kind of bottom separate type gas-atomized powder insulation crucible, belongs to field of material preparation.
Background technology
Gas atomization is widely used in the preparation of metal dust, particularly globular metallic powder.In powder by gas-atomization
During, the molten metal of melting need to successively flow through tundish inside holding crucible pot and mozzle, then be atomized through atomizer.Such as
The U of the Chinese utility model patent CN 203495240 and U of CN 203992414 are provided with insulation crucible, and are set in crucible bottom
It is equipped with mozzle.Because molten metal soaks the presence with surface tension effects, after the completion of powder by gas-atomization, crucible pot is incubated
Last-to-freeze liquid solidification in bottom and mozzle inevitably in the residual of some molten metal, particularly mozzle
It can not generally be melted again during next powder by atomization afterwards, it is necessary to changed, to avoid that blocking package occurs during next powder by atomization.However,
Insulation crucible pot is connected with each other with mozzle usually using screw thread, after the molten metal solidification of insulation crucible bottom of pot body residual,
Because adhesive attraction physically or chemically, insulation crucible pot can be sticked together with mozzle so that mozzle is difficult to take
Under, or causing insulation crucible bottom of pot body significantly to break ring after removing, influence is reused, and is incubated crucible as gas atomization
The critical component of powder manufacturing apparatus, it is overall frequently to change, it will to be obviously improved powder by gas-atomization cost.
Utility model content
The purpose of this utility model be overcome the shortcomings of above prior art exist there is provided a kind of bottom separated gas mist
Change powder processed insulation crucible, solve after powder by gas-atomization insulation crucible pot with mozzle because liquid bonding in frozen metal is difficult point
From the problem of, improve insulation crucible pot service life, reduce production cost.
The technical scheme of the insulation crucible is：A kind of bottom separate type gas-atomized powder insulation crucible, including crucible body,
It is described that every liquid funnel, crucible body bottom is set every liquid funnel and mozzle, it is brought into close contact every liquid funnel with crucible body bottom, crucible
Body every liquid funnel by mozzle with being fixed.
Crucible body is with being to be threadedly coupled by way of mozzle is fixed every liquid funnel.
Crucible body, the optional graphite of material and the ceramic material of aluminum oxide, zirconium oxide high-melting-point every liquid funnel and mozzle
Material.
Compared with prior art, the beneficial effects of the utility model：
(1) crucible body of the present utility model, detachable every liquid funnel and mozzle, can after the completion of powder by gas-atomization
It will be polished off every liquid funnel with crucible body and mozzle bonding part, replacing can be directly removed every liquid funnel and mozzle.
(2) the utility model change mozzle when, will not apparent damage crucible body, improve the use longevity of crucible body
Life, reduces the cost of powder by gas-atomization.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model bottom separate type gas-atomized powder is incubated crucible, and 1 is crucible in figure
Body, 2 be that 3 be mozzle every liquid funnel.
Embodiment
Principle of the present utility model and feature are described below in conjunction with the accompanying drawings, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
A kind of bottom separate type gas-atomized powder insulation crucible, as shown in figure 1, including crucible body 1, every the and of liquid funnel 2
Mozzle 3.The crucible body 1 is threadedly connected with mozzle 3, and the crucible body 1 is close to bottom and is provided with one
Every liquid funnel 2, it is brought into close contact every the lower surface of liquid funnel 2 with the bottom of crucible body 1, upper surface is reassembled into the bottom of crucible body 1
Funnel-form, it is described to be connected every liquid funnel 2 with mozzle 3 also by engagement thread.
Crucible body 1, the optional high-melting-point such as graphite and aluminum oxide, the zirconium oxide pottery of material every liquid funnel 2 and mozzle 3
Ceramic material.
After the completion of powder by gas-atomization, it will be polished off every liquid funnel 2 with the bonding part of mozzle 3, mozzle 3 is directly twisted
Under, crucible body 1 is removed every liquid funnel and given with being polished off every the junction overhead surface a thin layer metal of liquid funnel 2 afterwards
Change, last crucible body bottom will not substantially be destroyed, can be continuing with, and improve the service life of crucible body, reduce
The cost of powder by gas-atomization.
Embodiment 1
It is high-quality graphite that the present embodiment insulation crucible, which makes selected material, and metal used in gas atomization is 7075 aluminium alloys
(Si：≤ 0.40%, Fe：≤ 0.50%, 1.2%≤Cu≤2.0%, Mn：≤ 0.30%, 2.1%≤Mg≤2.9%, 0.18%
≤ Cr≤0.28%, 5.1%≤Zn≤6.1%, Ti：≤ 0.20%；Surplus is Al；Mass percent).Prepared in gas atomization
After the completion of 7075 Al alloy powders, it will be polished off every liquid funnel 2 with the bonding part of mozzle 3, mozzle 3 is directly backed out, afterwards by earthenware
Crucible body 1 is removed every liquid funnel 2 and changed with being polished off every the junction overhead surface a thin layer metal of liquid funnel 2, last earthenware
The bottom of crucible body 1 will not substantially be destroyed, and can be continuing with, while because of aluminium alloy low melting point, and the spy of different graphite reactions
Point, the reuse life-span of crucible body 1 is up to more than 10 times.
Embodiment 2
It is high-purity zirconia that the present embodiment insulation crucible, which makes selected material, and metal used in gas atomization is 304 stainless steels
(C：≤ 0.08%, Mn：≤ 2.00%, P：≤ 0.045%, S：≤ 0.030%, Si：≤ 1.00%, 18.0%≤Cr≤
20.0%, 8.0%≤Ni≤11.0%；Surplus is Fe；Mass percent).304 stainless steel powders are prepared in gas atomization to complete
Afterwards, it will be polished off every liquid funnel 2 with the bonding part of mozzle 3, mozzle 3 is directly backed out, afterwards by crucible body 1 and every liquid funnel 2
Junction overhead surface a thin layer metal is polished off, and is removed and is changed every liquid funnel 2, and the last bottom of crucible body 1 will not be by
To obvious destruction, it can be continuing with, while because stainless steel has high-melting-point, and ceramic material is through easy fragmentation of repeatedly expanding with heat and contract with cold
The characteristics of, the reuse life-span of crucible body 1 is still up to more than 5 times.
