Description
The EAF process reach different results during the different production periods depending by variabilities in operating practices applied, equipment’s efficiencies, scraps charged and hot heel present.
A mathematical tool for continuous monitoring of process performances and technological phenomena in EAF has been developed in collaboration between Feralpi Group and CSM to monitor steel/slag composition and temperature and also slag foaming effectiveness, energy losses, energy efficiency.
This approach has been used to evaluate the effectiveness of the new system for lime injection implemented in Acciaierie di Calvisano and to improve the necessary injection management to optimize process performances and final results of the application.
