Patent number: 7381366Abstract: An electroslag-cold hearth (ESCH) system for refining or producing a desired metal or metal alloy is described. The system includes at least one cold hearth vessel capable of holding a pool of molten liquid metal and an overlying slag layer, and an ingot mold laterally off-set from the cold hearth. A source of raw material, e.g., a feed electrode, is positioned above the cold hearth, and fed into the molten slag in a refining operation. A flow-over dam separates the ingot mold from the cold hearth, preventing the flow of inclusions and other foreign bodies into the ingot mold. In some instances, a non-consumable electrode provides additional thermal energy to the slag. In the production operation, the metal source can be a salt from which the desired metal can be electrochemically extracted. Related methods for refining or producing metals such as titanium alloys are also described.Type: GrantFiled: December 31, 2003Date of Patent: June 3, 2008Assignee: General Electric CompanyInventors: William Thomas Carter, Jr., Mark Gilbert Benz, Clifford Earl Shamblen, Andrew Philip Woodfield
