Description

Technical Field

[0001] The utility model relates to the technical field of graphite insulation barrels, in particular to a graphite insulation barrel with high efficiency in insulation. Background Art

[0002] At present, the production of graphite insulation barrels for molten single crystals and metals is achieved by mechanical processing of cylindrical graphite blanks. When making the finished graphite insulation barrels, the middle part of the cylindrical graphite blank needs to be hollowed out into a hollow cylinder, which results in a large waste of materials and a long production cycle during the production of the graphite insulation barrels. Most of the existing graphite insulation barrels have only one insulation layer, and the insulation effect is poor. In addition, the existing graphite insulation barrels have poor use strength, and are prone to rupture when subjected to external collisions. Therefore, we propose a graphite insulation barrel with high efficiency insulation. Utility Model Content
