FINEX

FINEX® — INNOVATIVE AND ENVIRONMENTALLY FRIENDLY IRONMAKING

Finex is an innovative ironmaking process based on the direct use of fine ore and non-coking coal.

In the Finex process, fine iron ore is directly charged at the top of a cascade of fluidized-bed reactors, where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas derived from the gasification of the coal in the melter gasifier. The DRI fines are processed into hot-compacted iron, transferred in hot condition to a charging bin positioned above the melter gasifier, and then charged into the melter gasifier, where melting takes place. The tapped product—liquid hot metal—is equivalent in quality to the hot metal produced in a blast furnace or Corex plant.
