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.
Claims18
A crucible apparatus for solidifying a molten material comprising:
- a hollow crucible body which is open at its upper and lower ends and a separate bottom plate 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 solidifying method for solidifying a molten material comprising:
- placing a crucible body which is open at its upper and lower ends atop a bottom plate to form a space for receiving a molten material;
- pouring a molten material into the space;
- solidifying the molten material inside the crucible body;
- removing the crucible body from the bottom plate;
- applying a force to one end of solidified material in the crucible body;
- and
- removing the solidified material from the crucible body.
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 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 solidifying method for solidifying a molten material comprising:
- placing a plurality of hollow crucible bodies each of which is open at its upper and lower ends atop a rotatable table to close off the lower end of each crucible body and form a plurality of spaces for receiving a molten material;
- rotating the rotatable table to successively position each of the spaces in a material receiving position and successively pouring a molten material into each of the spaces;
- solidifying the molten material poured into the plurality of spaces;
- removing the plurality of crucible bodies from the rotatable table;
- applying a force to one end of solidified material in each crucible body;
- and
- removing the solidified material from each crucible body.
