EAF In recent years, EAF process promoted the use of chemical energy for both enhancing productivity and reducing electricity consumption. Combined burners and sidewall oxygen lances are now currently operated in modern EAF. However, these tools are operated following pre-set patterns, without any feedback information from the process. This leads both to non-optimised operations and to occasional blow-back problems, resulting in damages to burners, lances, water-cooled panels and refractory lining.
