EAF AC
PROVEN TECHNOLOGY –HIGH PRODUCTIVITY
Based on decades of experience in designing electric arc
furnaces, Primetals Technologies offers steel producers
a broad range of powerful options for high-performanceelectric steelmaking.
This includes EAFs of all sizes and types, twin-shell
furnaces, and shaft furnaces in addition to all related
processes, automation, and environmental systems. The
AC EAF from Primetals Technologies is the ideal melting
unit for the production of all types of steel, from standard
carbon grades to high-alloyed and stainless steel grades. Itsoverall furnace performance can be further enhanced withthe latest oxygen and carbon injection technologies. Twinshell EAFs are a highly attractive solution for increasing aplant‘s productivity, especially when the lifting and loading
capacities of existing cranes and other infrastructurallimitations do not allow an increase in the tapping weight.
Poweroff times can be reduced to less than three minutes.

FEATURES• Gantry design for self-supporting furnace roof
• Prismatic roller guide system for electrode masts• High-current conducting electrode arms in copper-cladbox design• State-of-the-art electrode control system• Split-shell design• Copper or combi-panels with high-speed cooling waterflow• Oxygen and carbon injection• All bottom tapping systems (EBT, EO-EBT, RBT, OBT)
• Special hot-metal charging facilities• Continuous DRI/HBI feeding systems• DRI fines and dust injection
