Resumo
The electric arc furnace (EAF) technology has seen a continuous evolution in the last 50 years towards increased efficiency, with halved electric energy consumption, a four-time lower tap-to-tap time, electrodes consumption reduced more than five times (figure 1). These results have been achieved thanks to a combination of added chemical packages (oxygen blowing, burners), design improvement (water-cooled walls, EBT, lances, bottom stirring) and enhanced process controls. Another important tendency is the increase of maximum power for a single furnace, which has led to the development of EAFs capable of producing up to 300 tons of tap steel.
