3000KVA DC Electric Arc Furnace for Ferronickel Smelting
A small direct current smelting furnace for laterite nickel ore and nickel bearing residue. One 300mm graphite electrode against a conductive hearth anode holds a steady reducing arc over a deep bath, which protects nickel recovery in low tonnage operations where every percentage point of yield matters.
Core Selling Points
- Stepless thyristor regulation. DC current is held within plus or minus 1 percent, so arc power stays steady while bath level and slag condition change through the tap cycle.
- Nickel recovery above 92 percent. Steady arc power and deep bath coverage keep the reduction zone intact on screened laterite feed.
- Grid friendly at small scale. Flicker reduction above 50 percent and low harmonic emission let the unit run on a 10kV feeder without a dedicated static var compensator.
- Low graphite spend. Single electrode operation keeps consumption near 9 kg per tonne of alloy and removes two electrode columns from the maintenance routine.
- Small footprint, quick start. The unit ships as a skid mounted package, so installation and commissioning typically complete within six weeks on site.
