The FINEX Process :: Total Materia Article

Molten Iron is produced directly using iron ore fines and non-coking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route. In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron

FINEX® — ENVIRONMENTALLY SAFE IRONMAKING

In the Finex process, fine iron ore is 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 – that flows in the counter-current direction to the ore. The DRI fines are processed to hot-compacted iron

FINEX (steelmaking process) - Wikipedia

FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO.Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke.Elimination of preliminary processing is claimed to make the plant for FINEX less expensive to build than a blast ...

Alternative emerging ironmaking technologies for energy ...

01/05/2014  The major difference between the COREX and FINEX processes is that the FINEX process can directly use sinter feed iron ore (up to 0.012 m) , without agglomeration. The FINEX core plant consists of a melter-gasifier and a series of successive fluidized bed reactors that form a counter-flow system in which ore fines are reduced in three or four stages to DRI.

Alternative Iron making processess - SlideShare

18/01/2014  First, iron ore fines are reduced (de-oxidized) step by step in fluidized reduction furnace, and become bigger particles by HCI roller. Coking coals are processed to coal fines using special technology, and these fine particles are where the word FINEX comes from. Mixing these processed iron ores and coal fines in melting furnace completes FINEX process. Alternative Iron making processess

MIDREX Processes - KOBELCO

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with ambient oxygen, generate heat and occasionally ...

Iron Ore Sinter - an overview ScienceDirect Topics

The FINEX process is currently being operated at a scale of 1.5 Mt/yr hot metal [38]. The FINEX process is very similar to the COREX process; the major difference is that the FINEX process enables the direct use of sinter feed fine ore [37]. The scale of typical smelting reduction steelmaking plants is smaller than that of typical BF-based plants.

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and ...
