Remote cool down of a purified directionally solidified material from an open bottom cold crucible induction furnace |
摘要 |
Solid or semi-solid feedstock is melted in an open bottom electric induction cold crucible furnace. Directionally solidified multi-crystalline solid purified material continuously exits the bottom of the furnace and may optionally pass through a thermal conditioning chamber before being gravity fed into a transport mold where an ingot of the purified multi-crystalline solid material is transported to a remote holding area after the transport mold is filled with the multi-crystalline material and cut from the continuous supply of material. Cool down of the ingot is accomplished remote from the open bottom of the electric induction cold crucible furnace. |

1. A solidification process for a multi-crystalline material from a melt produced in an open bottom induction cold crucible, the solidification process comprising the steps of:
supplying a feedstock at the top of the open bottom induction cold crucible; forming the melt in the open bottom induction cold crucible by a magnetic flux coupling with the feedstock and melt combination when an alternating current flows through one or more induction coils surrounding the exterior of the open bottom induction cold crucible; forming from the melt a continuous supply of a hot solidified mass of a purified multi-crystalline material at the open bottom of the open bottom induction cold crucible; gravity feeding the hot solidified mass of the purified multi-crystalline material into a mold having a moveable inner bottom; controlling the rate of the gravity feeding of the hot solidified mass of the purified multi-crystalline material into the mold by a powered drive in communication with the moveable inner bottom of the mold; severing the hot solidified mass of the purified multi-crystalline material from the continuous supply of the hot solidified mass of the purified multi-crystalline material at the open bottom of the open bottom induction cold crucible; and moving the mold for remote directional solidification of the hot solidified mass of the purified multi-crystalline material in the mold without application of an external heating or cooling source. |
