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.
