Home Full portfolio DRI Smelting Furnace
The Metso Outotec DRI Smelting Furnace combined with direct reduction plant enables decarbonizing steel industry by replacing blast furnaces. Metso Outotec DRI Smelting Furnace furnace is based on proven proprietary equipment and enables utilizing blast furnace grade iron ore.
Solution introduction
  • High capacity 6-in-line DRI Smelting Furnace to replace blast furnaces (BF).
  • Can use direct reduced iron (DRI) made from BF - grade iron ore by enabling high slag volumes.​
  • Can be implemented next to existing BF for minimal production losses and a significant reduction in CO2 emissions with no changes needed to the rest of the steel plant.
  • An optimal solution based on proven technology for large-scale DRI smelting applications​.
  • Metso Outotec's extensive R&D capabilities have enabled filing of multiple patent applications​.

  • ~35 m length
  • ~11 m width
  • Up to 115 MVA apparent power
  • Up to 110 MW as design power

Efficient:

  • Hot DRI feeding to reduce energy consumption
  • Produced clean CO-gas usable to energy
  • High iron yield minimizing material losses (slag FeO < 3%)
  • Availability typically >95%

Flexible:

  • Metal tapped to granulation, ladles or torpedo car
  • Slag tapped to ground, slag pots or granulation
  • Large hot metal storage, continuous operation and high availability allows blast furnace type supply to downstream processes
  • Slag chemistry adjustable by application
  • Hot metal carbon content adjustable by application
