Graphite sagger is a commonly used container for sintering operations. The inner cavity of the graphite sagger is a rectangular parallelepiped, which includes four side panels and a bottom panel. The sizes of the graphite sagger are: 340×340×210mm, 340×340×170mm, 330×330×200mm, 330×330×170mm, etc. The graphite sagger in the prior art is an integrated structure. During processing, the graphite powder is placed in the corresponding mold, and then extruded into an integrated structure. This integrated structure is difficult to process and has high mold requirements (because the five surfaces need to be processed into one piece, and their strength must be guaranteed, so it is difficult). The integrated structure of this graphite sagger increases the difficulty and cost of manufacturing, and a little damage will cause the entire sagger to be scrapped, etc.

[0003] Therefore, how to provide a combined graphite sagger that reduces manufacturing difficulty and manufacturing cost, facilitates replacement of damaged parts, and is more practical is a technical problem that technicians in this field urgently need to solve. Utility Model Content
