Current status of the COREX( R )and FINEX( R ) processes
With the start-up of the COREX(R)C-3000 plant with an annual capacity of 1.5 Mt hot metal by Baosteel,China,a new milestone for the COREX technology could be reached.This module represents the up-scaling and the experiences made with the COREX plants in operation at Mittal Steel South Africa,at Jindal South West Steel,India and even the two FINEX(R)plants at Posco,Korea.Considerable changes in the raw material sector (iron ores,price of coke,coking coal and steam coal,etc.)and the general increase of energy cost (natural gas,electric power,etc.)in combination with the positive experiences during the operation and strictly enforced environmental laws make it worth today to carefully evaluate the COREX technology in comparison with the traditional blast furnace technology.Another development,the FINEX technology,is currently carried out by the operation of the FINEX Demonstration plant and by the FINEX 1.5 M Plant having an annual capacity of 1.5 Mt hot metal at Posco Pohang.Both plants operate successfully and will be path breaking for future ironmaking.Main focus of this presentation is laid on developments of the COREX technology,giving inside views about the operating COREX plants,new technological developments and factors endeavoring the COREX technology.Another focus is laid on the FINEX process showing the status,the results of the FINEX 1.5 M plant at Posco and the further steps in process development.
