Technical Field

[0001] The utility model relates to the technical field of single crystal manufacturing, and more specifically to a thermal field crucible for recycling waste parts. Background Art

[0002] The main purpose of the hot field crucible for producing single crystals by the direct pulling method is to serve as a hot field component in the process of single crystal growth. In the direct pulling method, the raw material is melted to form a melt, and then the melt is rotated and pulled to form a single crystal in the crucible. In this process, the crucible needs to withstand high temperature and corrosion. In the prior art, the utility model patent of Chinese Patent Publication No. CN217869200U discloses a nested spliced ​​combined insulation cylinder, which includes a cylinder body, a first fixed ring and a second fixed ring. The cylinder body is assembled by a plurality of cylinder pieces, and each cylinder piece is a nested spliced ​​cylinder piece. The first fixed ring is connected and fixed to the first end of the plurality of nested spliced ​​cylinder pieces. The second fixed ring is connected and fixed to the second end of the plurality of nested spliced ​​cylinder pieces. In this solution, a plurality of nested spliced ​​cylinder pieces are assembled to form a cylinder body, which helps to improve the overall connection strength of the insulation cylinder, thereby improving the service life of the insulation cylinder. However, the thermal insulation hot field crucible still has the following defects;

[0003] During the process of producing single crystals by the direct pulling method, the exterior and interior of the hot field crucible are damaged after the hot field crucible is used later, but the interior of the hot field crucible is intact. Therefore, directly discarding the entire hot field crucible will cause waste and greatly increase the cost of use. Therefore, a hot field crucible that can reuse waste parts is needed.
