Abstract
Tailored oxygen use has played a crucial role in EAF process improvement, enabling furnace operators to optimise chemical energy input, to achieve high efficiency and productivity. The fundamentals underlying an optimised chemical energy system, involving scrap oxycutting and melting, decarburisation, post-combustion and slag foaming, are described. This strategy is illustrated with industrial results obtained at the Vallourec and Mannesmann Saint-Saulve site, where a PyreJet and Alarc PC system, using the newly designed Dragon panel, has been recently commissioned.
