The technical solution of the utility model is that: the utility model provides a square graphite crucible of pin-connected panel, includes graphite bottom plate and the four graphite curb plates of being connected with the graphite bottom plate, four graphite curb plates enclose into square crucible body with the graphite bottom plate, peg graft each other between two adjacent graphite curb plates and be clearance fit, the socket and the inserted block at position of pegging graft each other are tenon fourth of the twelve earthly branches structure this internal four corners department of square crucible laminates the graphite spliced pole respectively, the graphite spliced pole is interior concave arc face with the face of not laminating of graphite curb plate, and its special character is: the binding face of graphite spliced pole and two adjacent graphite curb plates is vertically link up and is equipped with arch and the recess of mutual grafting respectively, arch and the recess that corresponds are dovetail and clearance fit each other.

Furthermore, the bulges are positioned on the surfaces of the corresponding graphite connecting columns so as to reduce the production cost of the graphite crucible, improve the strength of the whole structure and prolong the service life of the graphite crucible.

Furthermore, the fit clearance between the protrusion and the corresponding groove is less than or equal to 0.1mm.

Furthermore, the fit clearance between the socket of the plugging part and the plugging block is less than or equal to 0.1mm.

Furthermore, the two bulges and the two grooves corresponding to the same graphite connecting column are bilaterally symmetrical along the diagonal plane of the square crucible body passing through the graphite connecting column.

Further, there is the blind hole at the first half of the arc surface of graphite spliced pole along, through inserting when more damaged graphite curb plate the specialized tool of blind hole upwards proposes the graphite spliced pole, installs new graphite curb plate, inserts the graphite spliced pole from top to bottom in the graphite curb plate recess that corresponds again.

Furthermore, the inserting holes and the inserting blocks in the mortise and tenon structure are in a dovetail shape.

Furthermore, the inserting holes and the inserting blocks which correspond to each other in the mortise and tenon structure are connected through graphite screws I.

Furthermore, the graphite side plates are connected with the corresponding graphite connecting columns through graphite screws II.

The utility model has the advantages that: the graphite side plate has a relatively intact integral structure, and has no longitudinal pin holes on the surface, so that the strength of the graphite side plate is not damaged. The two graphite side plates are connected through the tenon-and-mortise structure and then are assembled in a convex-concave mode through the graphite connecting columns, so that the overall structural strength is improved, the connection is firmer, and the service life is long; the graphite connecting column is convenient to assemble, when a certain side plate is broken and lifted upwards, the broken graphite side plate is detached and replaced by a new graphite side plate, and the whole graphite crucible does not need to be replaced, so that the use cost is reduced.
