Document Type and Number:
WIPO Patent Application WO/2006/132016
Kind Code:
A1
Abstract:
A process for producing an ingot, in which even when a high-melting-point active metal, such as Ti, is contained, a large homogeneous ingot can be obtained economically. A large ingot is produced by casting an ingot from a melt obtained according to a cold crucible induction melting method, forming a consumable electrode from the ingot, re-melting the consumable electrode according to a vacuum arc re-melting method and casting the large ingot from the obtained melt.
