Abstract

<p>With the start-up of the COREX® C-3000 plant with an annual capacity of 1.5 million t 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, India and the two FINEX® 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. In addition to the first COREX Plant C-3000 in operation, Baosteel signed the contract for the second COREX Plant C-3000 in December 2007. Main focus of this presentation is laid on developments of the COREX technology, giving inside views about the operating COREX plants at Mittal Steel South Africa, Jindal South West Steel, especially the COREX plant C-3000 of Baosteel, the COREX plants under construction (Essar Steel), new technological developments and factors endeavouring the COREX technology.</p>
