(57) [Problem] To provide a durable graphite crucible resistant to impact and thermal shock. SOLUTION: A graphite crucible 1 is formed by press-molding by inserting a reinforcing muscle 2. The reinforcing bar 2 is formed by forming a wire 3 made of iron, stainless steel, titanium or the like into a cage shape. Reinforcing reinforcement 3 molded in a cage shape as a reinforcing metal member
And a perforated plate is press-molded and a bowl-shaped part or a cylindrical part is inserted and molded, so that a durable graphite crucible resistant to impact and thermal shock can be provided. Further, it is possible to provide a durable graphite crucible in which a specific portion of the graphite crucible is reinforced by inserting the bowl-shaped portion only into the bottom portion and inserting the cylindrical portion into only the cylindrical portion.

At this time, if an impact is applied to the graphite crucible, cracks or cracks occur. The graphite crucible is placed on a crucible and set in a melting furnace. In this case, a wedge is struck between the inner wall of the melting furnace and the graphite crucible to fix the graphite crucible so as not to move. In this case as well, when an impact is applied, it is similarly broken or cracked. Furthermore, cracking may occur due to thermal shock such as rapid thermal expansion during operation.
