The Digimelter for sustainable, competitive, green steelmaking
The Digimelter, sustainable, competitive, green steelmaking
A technological breakthrough in electric steelmaking, with lower power and electrode consumption thanks to the Q-One power feeder, for zero impact on the power grid and the possibility to use renewable energies.
Electric arc furnace technology has seen a continuous evolution in the last 50 years (see fig.1), towards increased efficiency, with electric energy consumption halved, tap-to-tap time reduced by four times, and electrodes consumption reduced more than five times. These results have been achieved thanks to a combination of chemical packages (oxygen blowing, burners), design improvement (water cooled walls, EBT, lances, bottom stirring) and enhanced process controls.
