Abstract
The utility model discloses a crucible for producing optical glass, comprising a metal matrix. The crucible for producing optical glass is characterized in that a high-temperature resisting sleeve is arranged in the metal matrix, and a vacuum cavity is arranged between the high-temperature resisting sleeve and the metal matrix, wherein the high-temperature resisting sleeve has a thickness of 6-15 mm, and the metal matrix and the high-temperature resisting sleeve are molded integrally. Compared with the prior art, the crucible for producing optical glass can meet the high temperature resisting requirement because the high-temperature resisting sleeve is arranged in the metal matrix and the metal matrix and the high-temperature resisting sleeve adopt vacuum isolation. In addition, the material cost of the crucible for producing optical glass is reduced, and the heat resistance is improved.
Description
Technical field
The utility model relates to optical field and makes the field, specifically is a kind of crucible of lanthanum.
Background technology
Crucible is a kind of device of founding opticglass, and the glass melting temperature of opticglass is general all at the above high temperature of 1000 degree, so crucible need adopt resistant to elevated temperatures material to process, generally adopts platinum.But the platinum material costs an arm and a leg, and requires investment big, and difficulty or ease are born.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and provides low being used to of a kind of cost to produce the crucible of opticglass.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of crucible that is used to produce opticglass; Comprise metallic matrix, it is characterized in that: in described metallic matrix, being provided with high temperature resistant cover, is vacuum cavity between this high temperature resistant cover and matrix.
The thickness of described high temperature resistant cover is 6～15mm.
Described matrix and high temperature resistant cover are one-body molded.
Compared with prior art, the utility model crucible is provided with high temperature resistant cover in matrix, and between matrix and high temperature resistant cover, adopts vacuum insulation, makes crucible can satisfy high temperature resistant requirement, and has reduced material cost, and resistance toheat also is improved.
Description of drawings
Fig. 1 is the utility model crucible structural representation.
Embodiment
Below in conjunction with accompanying drawing; The utility model is elaborated: as shown in Figure 1; A kind of crucible that is used to produce opticglass comprises integrated metallic matrix 1 and high temperature resistant cover 2 in the metallic matrix is set, and between this high temperature resistant cover 2 and matrix 1, is vacuum cavity 3; High temperature resistant cover 2 is generally made raw material by silica sand, clay, magnesite, rhombspar etc. and is made, and thickness is generally 6～15mm.
Claims (3)
