Yakov GordonHatchRising And Failure Of Gas Based Direct Reduction Processes Poveromo International Symposium (8th Intl. Symp. on Advanced Sustainable Iron & Steel Making) Back to Plenary Lectures » |
Abstract:The first industrial application of DRI production was Wiberg-Soderfors DRI shaft furnace process. The history of development and implementation of various gas based direct reduction processes was studied. The strength and week features of this processes were evaluated. It was shown that economics of the direct reduction process depends on cost of raw material and reducing agent, reliability of equipment and strict application of direct reduction principles. Results of evaluation allowed to show, why Midrex and HYL are the only successful DRI gas-based processes, while other lost their competitive position and stop operation |
