Abstract

As for the past 200 years, the coke or charcoal for electric blast furnaces has been the major economical basis for steelmaking. We can now introduce a new technological route, beginning with the COPEX® Process, which is a coal smelting reduction process. The COREC® Process is based on the use of a wide range of raw coals, including non-coking coal, which are diretamente fed into the process. The product from the COREC® Process is a hot metal of high purity. A byproduct is a medium BTU gas for export. The COREC® process development started in the late 1970s, and after successful small-scale tests in 1978, Korf Engineering and Voest Alpine AG, the owners of the COREC® Process, decided to build a semi-commercial demonstration plant. This COREC® plant at Kehl (Southern Germany) started the first test campaign in June 1981 with immediate success. The plant has now operated more than 6,000 hours with raw coal and iron ore from a great number of sources from all over the world.
