AST AC Graphite Electrode Furnace
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.
