| 摘要 |
An apparatus for melting an electrically conductive metallic material comprises an auxiliary ion plasma electron emitter configured to produce a focused electron field including a cross-sectional profile having a first shape. The apparatus further comprises a steering system configured to direct the focused electron field to impinge the focused electron field on at least a portion of the electrically conductive metallic material to at least one of melt or heat any solidified portions of the electrically conductive metallic material, any solid condensate within the electrically conductive metallic material, and/or regions of a solidifying ingot. |
