FINEX® — ENVIRONMENTALLY SAFE IRONMAKING

Finex is an innovative ironmaking process jointly developed by Primetals Technologies and the Korean steel producer Posco for the production of hot-metal – based on the direct use of fine ore and non-coking coal. In the Finex process, fine iron ore is charged at

Finex Process for Liquid Iron Production – IspatGuru

20/02/2013  This process is based on the direct use of non-coking coal. The FINEX process can directly use iron ore fines without any kind of agglomeration. In the FINEX process, fine iron ore is preheated and reduced to fine DRI (direct reduced iron) in three stage fluidized bed reactor system with reduction gas produced from melter gasifier. The fluidized bed reactors enable the FINEX process to use fine ores

The FINEX Process :: Total Materia Article

The Finex process is an innovative ironmaking process which has been developed by Siemens VAI and Posco. A schematic of the process is shown below: Figure 1: The FINEX process. 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

Finex Process Industrial Efficiency Technology Measures

Finex is a fluidized-bed smelting reduction process, and is considered to be a more advanced form of Corex process. Its core plant consists a melter-gasifier – which melts the DRI and gassifies the coal – and a series of successive fluidised beds that reduce ore fines to DRI. The technology utilizes fine ore and non-coking coal. Iron ore is first pre-reduced in fluidized-bed reactors by reducing gas coming from melter gasifier. Subsequently, hot metal is produced in the melter gasifier ...

28/06/2020  The FINEX is the latest addition and an optimized fine-ore smelting reduction (SR) iron making process based on the direct use of the coal and iron ore fines. FINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets.

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 furnace facility of the same scale, additionally a 10-15% reduction in production costs is expected/claimed through cheap

28/06/2020  FINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets. This is a process with great potential with regard to productivity and the low cost production of hot metal. In 1992, POSCO and VAI, Austria signed an agreement to work together for a joint development of the FINEX Process. And accordingly, FINEX process

FINEX® INE ORE REDUCTION PROCESS

The key technologies of FINEX are fluidized bed reduction of ore fines, hot DRI fines compaction to HCI(Hot Compacted Iron), briquetting of coal fines, and melting of HCI into hot metal. POSCO has been operating the world’s first commercial FINEX plant, with 1.5 MT of annual capacity, since April 2007 and has added up a new 2.0 MT in January 2014.

The World Leader in Ironmaking Solutions Primetals ...

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, transferred to a charging bin positioned above the ...

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.

System Dynamics Approach for the Impacts of FINEX ...

The new FINEX iron-making process, developed by POSCO,7 uses both fine coal and fine iron ore, making it more cost effective than the similar Corex process, and emission are almost 80% less than those of the blast furnance process (Ramstad, 2008). It is, thus, important to compare the iron and steel industry in Korea with the other Korean industries for GHG emissions 10.1007/s40684-015-0011-1 ...
