Abstract
Most high productivity electric arc furnace (EAF) melt shops employ significant amounts of chemical energy in the melting process. Goodfellow's EFSOP technology uses continuous offgas analysis plus process monitoring to optimise the use of chemical energy in the EAF. Benefits include savings in electrical energy, gas, oxygen and carbon, which result in significant reductions in conversion costs and increased productivity. Recent results from the installation of KT injectors and EFSOP at Tamsa are presented, together with operational results from other recent North American plants. Finally, an innovative development programme based on yield improvements in EAF steelmaking via improved process modelling and control methods is described.
