SOLIDIFICATION OF MOLTEN MATERIAL OVER MOVING BED OF DIVIDED SOLID MATERIAL |
摘要 |
Systems and methods for converting a powder to a solid mass are disclosed. A furnace is provided to melt the powder and deliver a stream of resulting molten material to a bed of beads on a vibratory conveyor. Cooling gas flows through nozzles positioned above and along the conveyor to cool the beads and liquid. The liquid solidifies and forms a solid mass, incorporating beads from the bed. The conveyor can be periodically stopped to produce a plurality of discrete solid masses. Masses and unincorporated beads fall into a collection container. Unincorporated beads pass through a screening device and are returned to the bed of beads. A make-up bead system adds beads to the bed as needed to maintain a suitable bed depth. In some embodiments, the powder and beads consist essentially of silicon, and the solid masses formed are suitable for preparing silicon ingots. |
