    摘要: A method for producing a metal ingot by using an electron-beam melting furnace having an electron gun and a hearth that accumulates a molten metal of a metal raw material, wherein the metal raw material is supplied to the position on a supply line disposed along a second side wall of the hearth that accumulates the molten metal of the metal raw material. A first electron beam is radiated along a first irradiation line that is disposed along the supply line and is closer to a central part of the hearth relative to the supply line on the surface of the molten metal, wherein a surface temperature (T2) of the molten metal at the first irradiation line is made higher than an average surface temperature (T0) of the entire surface of the molten metal in the hearth.

    摘要: 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.
