With the contract award for a COREX C-3000 plant with an annual capacity of 1.5 million t hot metal by Baosteel Pudong ISCO, PR China, a new milestone for the COREX technology could be reached. This module represents the up-scaling and the experiences made with the COREX currently being in operation. Changes in the raw material sector (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 make it worth today to carefully evaluate the COREX technology in comparison with the blast furnace technology. Another development, the development of the FINEX technology, is currently carried out by the operation of the FINEX Demonstration plant and by the installation of a FINEX 1.5M Plant having an annual capacity of 1.5 million tons hot metal at POSCO Pohang. One main focus of this presentation is laid on developments of the COREX technology, giving inside views about status of the operating COREX plants, new technological developments and factors endeavoring the COREX technology. Another focus is laid on the FINEX process showing the status and the further steps in process development.
