Baosteel Special Steel has recently ordered from Danieli Service China the innovative Q-PANELS, an eco-friendly OPEX-saving technological package, for its existing stainless steel EAF, to limit specific electrical consumption, reduce unplanned down-times and increase operational safety.
After three months of its production, the FAC was signed, proving the Q-PANELS potential and allowing, thanks to the process improvement resulting from the Q-PANELS installation, an OPEX saving of approx. EUR 4 on, thus enabling a fast return on investment (ROI < 2 months).
All this was possible because of the innovative design that entraps the slag between the two layers of spaced tubes. The slag acts as a heat insulator, thus decreasing the water-cooled surface exposed to heat radiance, resulting in 25% less energy loss and a lifetime of more than 20,000 heats.
