Outotec® SAF Smelting Plant

Get low raw material consumption, high metal recovery, and low CO₂ and dust emissions. The Outotec submerged arc furnace (SAF) is a closed-type, environmentally friendly, and energy-efficient solution for ferroalloys. Preheating removes water and volatiles, stabilizing process conditions and decreasing the specific energy consumption of the furnace.

  • Minimizes energy, coke, and electrode paste consumption    
  • Offers high productivity and metals recovery, especially with pellets    
  • Enables effective utilization of cleaned CO gas in different plant applications    
  • Preheats up to 600ºC, with every 100ºC saving 70 kWh per metric ton of metal in smelting    
  • Gives you low operational costs and low CO₂ and dust emissions
