Abstract
A method for refining and casting metals and metal alloys includes melting and refining a metallic material and then casting the refined molten material by a nucleated casting technique. The refined molten material is provided to the atomizing nozzle of the nucleated casting apparatus through a transfer apparatus adapted to maintain the purity of the molten refined material. An apparatus including a melting and refining apparatus, a transfer apparatus, and a nucleated casting apparatus, in serial fluid communication, also is disclosed.
Claims6
An apparatus for providing a preform of a metallic material by nucleated casting, the apparatus comprising:
- a melting and refining apparatus selected from an electroslag remelting apparatus and a vacuum arc remelting apparatus;
- a transfer apparatus including a passage therethrough terminating in an orifice, said transfer apparatus in fluid communication with said melting and refining apparatus;
- and
- a nucleated casting apparatus in fluid communication with said transfer apparatus, wherein the nucleated casting apparatus comprises a mold in which the preform is formed, the mold comprising a side wall and a base.
