Production of large homogeneous ingots of macrosegregation sensitive reactive alloys by the vacuum consumable arc remelting process depends on reliable control of the furnace. Such control is possible only when the normal operation is understood. A tightly coupled theoretical-experimental-numerical program has been under way for some time at Sandia in conjunction with other DOE and private facilities, aimed at achieving this understanding. The furnace arc and electrode surfaces have been studied by high speed cinematography, showing that basic arc behavior is similar to that reported in the arc physics literature for vacuum breaker switches with cold (unmelted) electrodes.
