A/C Graphite Electrode Furnace
  • Arc rotates between three electrodes
  • Rotation of arc imparts stirring to bath, increasing furnace efficiency
  • Brush-arc mode for electrodes concentrates heat at bath’s surface where most needed for gasification reactions
  • Electrode consumption slower compared to DC furnaces
  • Graphite electric arc furnace most commonly used type in steel making and metal smelting operations
  • AST’s extruder type feeder introduces waste at side of furnace, eliminating extraneous air in the system, resulting in cleaner, richer syngas.
