Abstract
The utility model relates to an assembled graphite crucible for induction heating, which is made of graphite, and is characterized in that the crucible is basically divided into an upper part and a lower part which can be detached and assembled, wherein the upper part of the crucible is generally made of electrode graphite, and the lower part thereof is made of high-purity high-density graphite. By adopting the structure, not only the structure size of the crucible is maintained, but also the cost of the whole crucible is relatively low, and the crucible can be stably used.
Description
Technical field
The utility model relates to the technical field of apparatus for melting metal on a small scale, especially for the graphite crucible of eddy-current heating.
Background technology
Graphite crucible is in the extensive use of metal casting melting industry, but occasion at some specific use eddy-current heating, because the thickness to crucible has certain requirement, so in selection, generally select for use density is higher and unfailing performance is comparatively stable high purity graphite as the crucible materials, but the cost of high purity graphite is higher.Based on cost consideration; also once attempted using a little and the electrode graphite that low price is many of material difference as the crucible materials; but because density and porosity problem that the difference of the production technology of electrode graphite material causes; the phenomenon of the seepage that occurs through regular meeting in use; the serious phenomenons such as intermediate frequency coil burns, short circuit tripping operation that directly cause have influenced production efficiency and cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of both kept existing crucible physical dimension, whole crucible cost also relatively low, can stablize the pin-connected panel graphite crucible that is used for eddy-current heating that uses.
The purpose of this utility model is achieved by the following technical solution: a kind of pin-connected panel graphite crucible that is used for eddy-current heating, the material of crucible base is a graphite, it is characterized in that: crucible base is divided into two parts up and down of detachable assembly unit, crucible top is general electrode graphite, and the crucible bottom then is a high-purity high-density degree graphite.Further, the height of crucible top and the bottom binding site is designed to be higher than metal liquid level 5CM after the fusion.Adopt the form of concavo-convex complementation to combine between the higher and lower levels between the crucible top and the bottom.
Adopt above-mentioned improved structure, compare with traditional graphite crucible, the utlity model has following beneficial effect: owing on the structure of graphite crucible, done the adjustment of a collocation material, make level of molten metal be lower than the height of high-purity high-density degree graphite, mix remaining 1/3 high electrode graphite again, the consumption of high-purity high-density degree graphite is greatly reduced, therefore reduced production cost, and then improved production efficiency.
Description of drawings
Fig. 1 is the utility model graphite crucible upper and lower part structure partition schematic diagram;
Fig. 2 is assembling back, a utility model graphite crucible top and the bottom structural representation.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the crucible of present embodiment has adopted the structure of pin-connected panel up and down, and the high high-purity high-density degree graphite of density, the electrode graphite that crucible top 1 then adopts quality to take second place are adopted in crucible bottom 2.Crucible top 1 is to adopt the general layout that goes up under the cover with the erection method method of crucible bottom 2, binding site adopts concavo-convex mode to carry out combination, and the high purity graphite of crucible bottom 2 adopts its recess design---at binding site, car falls outer ring certain size graphite, allow it keep certain thickness, form similar recess; And crucible top 1 graphite adopts the design of protruding position---at binding site, car falls inner ring certain size graphite, allows it keep certain thickness, forms similar protruding position, and the inner ring size of this protruding position is less than recess outer ring, bottom 0.1mm on tolerance.Up and down certain binding agent is smeared in the protruding position of recess when mounted, and it is granted certain pressure pressure gets final product; Simultaneously the height of binding site is designed to be higher than metal liquid level 5CM after the fusion.
Certainly, only enumerated some preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
Claims (3)
1. pin-connected panel graphite crucible that is used for eddy-current heating, the material of crucible base is a graphite, it is characterized in that: crucible base is divided into two parts up and down of detachable assembly unit, and crucible top is general electrode graphite, and the crucible bottom then is a high-purity high-density degree graphite.
2. graphite crucible according to claim 1, the height that it is characterized in that crucible top and the bottom binding site are designed to be higher than metal liquid level 5CM after the fusion.
