Abstract
The invention discloses an insulation cylinder used in a laser crystal growth process. The invention is characterized in that the insulation cylinder is in a split structure, i.e. the whole insulation cylinder is split into unit components which can be mutually spliced to form a cylindrical body. The invention can effectively avoid thermal deformation due to different thermal expansion systems, thereby ensuring the reliability of the production process.
Description
Technical field
The present invention relates to the crucible insulation device in a kind of process of growth that is applied in laser crystals.
Background technology
Laser crystals is widely used in fields such as space flight and aviation, industry, military affairs, medical treatment, and the production technique of laser crystals also is to improve in improvement for many years and development, and the shove charge equipment of laser crystals mainly still is the different size made of raw material, the lagging material of different indexs with the zirconium white at present.The process of laser crystal growth is a good process of high-temperature stability, if the crucible lagging material is out of shape because of high temperature, or even cracking, the warm field system that has designed moulding then can be changed, this will increase production cost greatly, increase the risk of growing crystal greatly.
The integral body of the growth of laser crystals is divided into two parts up and down, and at the insulation of lower part, original structure is the zirconium white thermal insulation layer cylindraceous that an integral body is arranged in the outside of crucible, and the thickness of thermal insulation layer is 14-17mm, highly is 180-200mm.In the pyroprocess of crystal growth, it is to be in more than 1200 degrees centigrade that most time is arranged.And having the zirconium white thermal insulation layer in the structure owing to adopt one-piece construction, its thickness is bigger, is difficult to guarantee the unanimity of thermal insulation layer density when making.In hot environment, the thermal insulation layer density less place that compares, thermal expansivity will be corresponding littler, the thermal expansivity that density is big is then big, for an one-piece construction, the different thermal expansion meeting on the different positions deforms one-piece construction, even cracking.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of heat-preservation cylinder that is applied in the laser crystal growth process is provided, the thermal distortion of avoiding the difference owing to hot expansion system to take place, thus guarantee the reliability of production process.
Technical solution problem of the present invention adopts following technical scheme:
The constructional feature that the present invention is applied in the heat-preservation cylinder in the laser crystal growth process is: heat-preservation cylinder is set for dividing body structure, described minute body structure is that whole heat-preservation cylinder split is set to each unit member, and described each unit member is spliced to form cylindrical body mutually.
The constructional feature that the present invention is applied in the heat-preservation cylinder in the laser crystal growth process also is:
Being distributed as of each unit member in the described heat-preservation cylinder: described heat-preservation cylinder is set is the overlaying structure of a plurality of annulus in the axial direction, described each annulus is divided into each tile shape on circumference; Be that step surface is rabbeted mutually between the adjacent tile.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention splits the one-piece construction of heat-preservation cylinder, each unit member after the fractionation is because volume is little, itself is very little in the difference of coefficients of the thermal expansion at different positions place, therefore heat distortion amount is very little, therefore greatly reduces in the existing structure because the increase of the production cost that thermal distortion may bring and the risk of crystal growth.
2, of the present invention minute body structure makes and can split arrive each piece tile for the maintenance of heat-preservation cylinder, and, because each piece tile can independently be changed, greatly reduce maintenance cost, and maintenance service is very convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a unit member synoptic diagram of the present invention;
Number in the figure: 1 heat-preservation cylinder; The 1a unit member; The 1b tile;
Embodiment
Referring to Fig. 1, Fig. 2, heat-preservation cylinder 1 is set for dividing body structure in the present embodiment, dividing body structure is that whole heat-preservation cylinder 1 split is set to each unit member 1a, each unit member 1a is spliced to form cylindrical body mutually.
In concrete the enforcement, being distributed as of each unit member 1a in the heat-preservation cylinder 1:
Heat-preservation cylinder 1 is set is the overlaying structure of a plurality of annulus in the axial direction, each annulus is divided into each tile shape on circumference; Be that step surface is rabbeted mutually between the adjacent tile.
Annulus shown in Figure 2 is divided into six tile 1b on circumference, the central angle of every tile 1b is 60 degree, highly is 50-55mm, and interior radius of circle r is 170-180mm, exradius R is 185-197mm, is to rabbet mutually with step surface between the adjacent tile 1b on the annulus; According to present growth technique, the number of plies of synergetic annulus generally is the 4-7 layer, and interlayer keeps verticality can form whole heat-preservation cylinder structure when mounted.
Each piece tile 1b in the present embodiment can change separately, and this form has greatly reduced production cost, and in the design of temperature field, can more easily change and adjust.
In the concrete construction, correct with concentric(al) circles after coincideing each layer well, finally reach vertical and concentric requirement, stack is successively finished up to whole insulation construction again.
