Example Embodiment

[0015] See figure 1 , figure 2 In this embodiment, the thermal insulation cylinder 1 is set as a split structure, and the split structure is to split the entire thermal insulation cylinder 1 into unit components 1a, and the unit components 1a are spliced ​​with each other to form a cylindrical body.

[0016] In specific implementation, the distribution of each unit component 1a in the heat preservation cylinder 1 is:

[0017] In the axial direction, the heat preservation cylinder 1 is a superimposed structure of multiple circular rings, and each circular ring is equally divided into the shape of each tile on the circumference; the adjacent tiles are embedded with each other by step surfaces.

[0018] figure 2 The ring shown is equally divided into six tiles 1b on the circumference. The central angle of each tile 1b is 60 degrees, the height is 50-55mm, the inner radius r is 170-180mm, and the outer radius R is 185. -197mm, the adjacent tiles 1b on the ring are embedded with each ...

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 [0001] The invention relates to a crucible heat preservation device used in the growth process of laser crystals. Background technique [0002] Laser crystals are widely used in aerospace, industry, military, medical and other fields, and the production process of laser crystals has also been perfected and developed in years of improvement. At present, the furnace equipment for laser crystals is mainly made of zirconia. Insulation materials of different specifications and indicators. The process of laser crystal growth is a process with good high temperature stability. If the crucible insulation material is deformed or even cracked due to high temperature, it will change the designed temperature field system, which will greatly increase the production cost and greatly increase the growth rate of the crystal. risks of. [0003] The growth of the laser crystal is divided into upper and lower parts as a whole. For the insulation of the lower part, the original...
