Spliced combined crucible edge for single crystal furnace

The utility model relates to the technical field of Czochralski single crystal, and provides a spliced combined crucible edge for a single crystal furnace, which comprises an outer-layer component and an inner-layer component, the outer-layer component is integrally of a cylindrical structure, and the inner-layer component is integrally of an arc-shaped structure and is attached to the inner side wall of the outer-layer component; a plurality of inner-layer components are evenly distributed around the middle of the outer-layer component and completely cover the inner side wall of the outer-layer component. The inner-layer component is combined with the outer-layer component in a splicing mode to form the crucible edge with the splicing structure, compared with a traditional integrated crucible edge, the cost is reduced, only a damaged part needs to be replaced if the crucible edge is damaged, the whole crucible edge does not need to be replaced, and maintenance is very convenient. 本实用新型涉及直拉单晶技术领域，提供一种单晶炉用拼接组合
