FINEX: a New Iron-making Technology made by POSCO, S. Korea. Advanced countries started developing various new iron-making processes in the 70s, ten to twenty years earlier than POSCO. Substandard technologies of local partners in S. development projects require much cooperations with local partners.

Advantage: Smelting Reduction Processes They produce hot metal; hence . Level of development. Ability to use ore fines Reductant

Advantage: Smelting Reduction Processes They produce hot metal; hence more relevant to BOF based Integrated Steel Plants Direct use of non-coking coal and Iron ore fines They need much less land as compared to conventional BF complex. Ability to use ore fines Reductant. Oxygen (Nm3, thm), HM Quality. For COREX & FINEX processes, rich off gas generated in the process need to be used either for generation of power or for production of DRI. Hismelt is suitable for steel product with low P. RDCIS 31.

iron-making process → POSCO: the latecomer succeeded in Facility 100%(BF) commercializing 1mt of annual production investment cost(per ton) 80%(FINEX) for the first time in the world.

3 Historical Cyclosteel process. The "pellets" refer to an intermediate product of the steelmaking process used by Tata IJmuiden and other ULCOS partners. Before introducing iron to the blast furnace, they process raw ore into pig-iron/coal pellets. These pellets are very porous, which creates a large reactant surface of pig iron and coal for the hot air in the blast furnace. Similar to ROMELT, but more a mutation of a Blast Furnace and Basic Oxygen Furnace (BOF) vessel is HISMELT developed by a Rio Tinto Group subsidiary (also named HISMELT ).

In the Corex process, all metallurgical work is carried out in two separate process reactors – the reduction shaft and the melter gasifier. Since coking and sintering plants are not required for the Corex process, substantial cost savings of up to 20% can be achieved in the production of hot metal, of a grade similar to that of the blast furnace. Regarding environmental concerns, Corex plant emissions contain only insignificant amounts of NOx, SO2, dust, phenols, sulfides and, ammonia. Emission values are already far below the maximum values allowed by future European standards.

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal. The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place

In the course of a DFG-funded project, the organisation of iron smelting and iron working in the Jastorf culture was characterised for the first time

In the course of a DFG-funded project, the organisation of iron smelting and iron working in the Jastorf culture was characterised for the first time. In the course of a DFG-funded project, the organisation of iron smelting and iron working in the Jastorf culture was characterised for the first time. The project focused on the Teltow area, a morainic landscape south of Berlin which offers diverse natural resources.

This work deals with the topic of how a new smelting reduction process influenced the iron and steel making industry till today. It covers the history of the iron and steel production, the development of the COREX® plant and the influence of environmental restrictions and future perspectives for this iron-making process. COREX® was the first industrial smelting reduction process just driven by normal coal, which is available all over the world. It started with promising test results at a time engineers were of the opinion that this process will revolutionize the whole iron market. Somehow it did but difficulties occurred, technical as well as economical ones, which slowed down the COREX®'s way of success.
