Abstract
A crucible apparatus includes a hollow crucible body which is open at its upper and lower ends and a bottom plate which is formed separately from the crucible body and can close off the lower end of the crucible body. A space for receiving a molten material is formed by placing the crucible body atop the bottom plate. When molten material received in the space has solidified, the crucible body is raised off the bottom plate, and solidified material is pushed out of one end of the crucible body and removed from the crucible body.
Claims20
A crucible apparatus for solidifying a molten material comprising:
- a hollow crucible body which is made of copper or graphite and which is open at its upper and lower ends and which has an exterior wall extending between the upper end and the lower end of the crucible body without any openings communicating between the interior and the exterior of the crucible body, and a separate bottom plate which is made of copper and which can close off the lower end of the crucible body, a space for receiving a molten material being formed by placing the crucible body atop the bottom plate.
A crucible apparatus for solidifying a molten material comprising:
- a plurality of hollow crucible bodies, each of which is open at its upper and lower ends and has an exterior wall extending between its upper and lower ends without any openings communicating between the interior and the exterior of the crucible body, and a rotatable table which can support the plurality of crucible bodies and close off the lower end of each crucible body, a plurality of spaces for receiving a molten material being formed by placing the crucible bodies atop the rotatable table.
A crucible apparatus for solidifying a molten material comprising:
- a plurality of hollow crucible bodies, each of which is open at its upper and lower ends and has a slit extending from its upper end to its lower end, and a rotatable table which can support the plurality of crucible bodies and close off the lower end of each crucible body, a plurality of spaces for receiving a molten material being formed by placing the crucible bodies atop the rotatable table.
