This paper analyzes the latest results achieved in scrap-based EAFs in terms of application of chemical energy, starting from the observation that the general trend is a reduction of oxygen utilization. If the maximization of productivity is to remain one of the major goals, then some aspects of the present market situation, including the price of raw materials, are required to maximize process yield. Based on performance figures of selected plants and theoretical considerations, the effect of chemical energy input intensity is analyzed, focusing on transformation cost, productivity and total energy input. The effect of present practices with lower oxygen utilization is considered also in terms of global CO2 emissions. Finally, Danieli's latest concepts and technological tools for optimization of chemical input are presented.
