Germany-based plantmaker SMS Siemag has announced that it has developed a new electric arc furnace called ARCCESS steady EAF (S/EAF) that allows continuous operation for up to one week.
This new type of electric arc furnace yields a 30 percent higher productivity with lower energy consumption thanks to its reliable 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.
The S/EAF is continuously charged with direct-reduced iron ore (DRI/HBI), hot metal or scrap through a material handling system that is also rated for the use of 600°C hot DRI. Continuous operation is interrupted only for regular maintenance work.
