Title:
PROCESS FOR PRODUCING TITANIUM OR TITANIUM ALLOY INGOT
Document Type and Number:
WIPO Patent Application WO/2010/021250
Kind Code:
A1
Abstract:
A process for producing a titanium or titanium alloy ingot through consumable-electrode vacuum remelting. The process eliminates the uneven distribution of raw materials among compacts and in the individual compacts, to be used as a consumable electrode in the process, and thereby gives an ingot free from inhomogeneity. Titanium sponge particles and other particulate raw materials are charged, in respective amounts corresponding to one compact, into a mixing vessel (10) from hoppers (21a to 25a) via weighing devices (21b to 25b). The mixing vessel (10) into which the raw-material particles have been charged in an amount corresponding to one compact is biaxially rotated in a mixing part (30) with a mixer. The raw-material particles in the mixing vessel (10) are forcibly stirred efficiently to give a raw material mixture reduced in the uneven distribution of the raw materials.
