Enhancement of EAF performance with the efficient use of exothermic energy

摘要

Three highly productive EAF shops in S. Korea (Korea Iron and Steel, Inchon Iron and Steel and Kangwon Industries) have upgraded their furnaces with the installation of the PYRETRON Clean Melt System provided by American Combustion. The PYRETRON Clean Melt System is an integrated system for supplying exothermic energy into the EAF via combustion of hydrocarbon fuel, oxidation of the iron-carbon melt and the post-combustion of CO. The system includes a set of side wall burners and a slage door manipulator carrying a water-cooled supersonic oxygen lance and a burner/carbon injector lance equipped with post-combustion oxygen injection nozzles. A dedicated computerized process control allows for integrated operation of all components of the system.
