SMS Siemag developed a new electric arc furnace (EAF) for continuous operation.
The ARCCESS® steady EAF (S/EAF®) allows real continuous operation for up to one
week. It yields 30% higher productivity with lower energy consumption thanks to
its continuous process. The integrated energy recovery system further improves
efficiency by utilizing the thermal energy of the hot furnace off-gas. All
components have been designed to allow continuous power-on operation for around
one week. Uninterrupted operating practice is made possible by a patented system
derived from SAF technology, which allows the electrodes to be clamped and
slipped continuously. Whenever an electrode has been used up, a fresh piece of
electrode is joined on at its end.
