SMS group Tapped for EAF Power Feeder System
11/27/2024 - SMS group has been contracted to integrate an electrical direct feed system into a new electric arc furnace being built at SSAB’s Oxelösund steel plant in Sweden.
According to SMS group, the GE Vernova-built system will ensure the new electric arc furnace operates smoothly and efficiently without disrupting the grid, thereby contributing to the reduction of CO2 emissions.
The modular multilevel converter system will be an indirect power supply built on injection-enhanced gate transistor technology and designed specifically for EAFs. The system includes two parallel converter lines installed at 300 m and 400 m from the EAF, directly connected to the 34 kV bus. This setup mitigates flicker, maintains very low harmonics, and ensures a unified power factor SMS group said.
“This project is a significant step forward in our journey towards sustainable steelmaking. Powering the furnace with a fast digital control system will enable SSAB to achieve their targets in terms of power quality and efficiency,” said Jan Heimann, executive vice president of SMS group.
Powered by a 280 MVA transformer, the 190-ton EAF will be one of the largest installations in the world with an upper shell diameter of 9.3 meters. SMS group is building the furnace, which is scheduled to go online in the fourth quarter of 2026.
