Abstract
The invention discloses a graphite crucible cover. The graphite crucible cover comprises a graphite crucible cover body made of natural graphite. The crucible cover body is of a conical structure. A conical cavity is formed in the crucible cover. Four symmetrical round holes are formed in the curved surface of the side face of the crucible cover body. Outside air is communicated with the cavity in the crucible cover through the round holes. A shackle is arranged on the conical top of the crucible cover body. The conical apex angle in the vertical section of the crucible cover body is an acute angle. In this way, the graphite crucible cover is simple in structure; different from common planar crucible covers, the graphite crucible cover is of a hollow cone shape, the conical apex angle is arranged to be the accurate angle, the through holes are further formed in the conical side surface, and therefore a heated object in a crucible can be effectively prevented from jumping out, and it is also guaranteed that the outside air can freely get into and out of the graphite crucible for an oxidation reaction; the graphite crucible cover is high in practicality and has certain economic benefits and market prospects.
Description
Technical field
The present invention relates to graphite product field, particularly relate to a kind of graphite crucible lid.
Background technology
Graphite crucible has good thermal conductance and heat-resisting quantity; be widely used in the smelting of alloy tool steel and the melting of non ferrous metal and their alloy; graphite crucible lid is then its indispensable supporting goods; for prior art; graphite crucible lid mostly in the market is plane cover plate structure, being difficult to of enclosed construction allows air carry out oxidation reflection, and is provided with through hole; the thing that is heated usually can be jumped out in thermal histories, there is certain defect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of graphite crucible lid, can effectively prevent the thing that is heated in crucible from jumping out, and ensure that extraneous air can free in and out graphite crucible inside and carry out oxidation reaction.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of graphite crucible lid, it is characterized in that, comprise: adopt the graphite crucible lid body that native graphite is made, described crucible cover body is conical structure, crucible cover inside is a conical cavity, the curved surface of described crucible cover body side is provided with four symmetrical circular holes, described circular hole is by extraneous air and crucible cover internal cavities UNICOM, the conical top of described crucible cover body is provided with a shackle, in described crucible cover body vertical cross-section, circular cone corner angle is acute angle.
In a preferred embodiment of the present invention, the making material of described graphite crucible lid body comprises fire clay, aggregate, natural graphite, and its ratio carries out adjustment processing and fabricating according to the not same-action of crucible.
In a preferred embodiment of the present invention, the vertical cross-section angular range of the top conical of described crucible cover body is 15 °-60 °.
In a preferred embodiment of the present invention, described shackle is used for fetching of described crucible cover body.
In a preferred embodiment of the present invention, described center of circular hole is positioned on same level cross section, and symmetrically.
The invention has the beneficial effects as follows: structure of the present invention is simple, be different from common plane crucible cover, this graphite crucible lid is cavity conical shell, circular cone drift angle is arranged to acute angle, and through hole is set at conical side surface, not only can effectively prevents the thing that is heated in crucible from jumping out, and ensure that extraneous air can free in and out graphite crucible inside and carry out oxidation reaction, practical, there are certain economic benefit and market prospects.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the cross-sectional view of a kind of graphite crucible lid one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1-graphite crucible lid body, 2-circular hole, 3-shackle.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of graphite crucible lid, it is characterized in that, comprise: adopt the graphite crucible lid body 1 that native graphite is made, described crucible cover body 1 is conical structure, crucible cover inside is a conical cavity, the curved surface of described crucible cover body 1 side is provided with four symmetrical circular holes 2, described circular hole 2 is by extraneous air and crucible cover internal cavities UNICOM, the conical top of described crucible cover body 1 is provided with a shackle 3, and in described crucible cover body 1 vertical cross-section, circular cone corner angle is acute angle.
Be different from prior art.
In another embodiment, the making material of described graphite crucible lid body 1 comprises fire clay, aggregate, natural graphite, and its ratio carries out adjustment processing and fabricating according to the not same-action of crucible.
In another embodiment, the vertical cross-section angular range of the top conical of described crucible cover body 1 is 15 °-60 °, and the side of described crucible cover body and the angle of horizontal plane are comparatively large, and the thing that is heated in crucible is more not easily jumped out.
In another embodiment, described shackle 3 fetching for described crucible cover body, prevents from scalding, fetches conveniently.
In another embodiment, described circular hole 2 is centrally located on same level cross section, and symmetrically, regularly arranged.
Structure of the present invention is simple, be different from common plane crucible cover, this graphite crucible lid is cavity conical shell, circular cone drift angle is arranged to acute angle, and at conical side surface, through hole is set, not only effectively can prevent the thing that is heated in crucible from jumping out, and ensure that extraneous air can free in and out graphite crucible inside and carry out oxidation reaction, practical.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
