Japan’s leading flat steel producer Shinkansai Steel Co will implement the patented Danieli Q-One technology on the 74-tonne tapping capacity electric arc furnace in operation at its Sakai plant. Designed by Danieli Automation, Q-One uses the latest digital power electronics technology to maintain the EAF power-factor values close to unity.This power-feeding system will have a five-unit configuration with a total maximum power of 54.6 MVA. By controlling electrical current, voltage and frequency during melting to maintain optimal levels according to changes within the electric furnace, the consumption of electricity and electrodes will be reduced, leading to energy and operating cost savings in the steelmaking process.Thanks to the Q-One design concept, which offers unmatched power control and power management, Shinkasai’s EAF will not require any SVC system.The project is expected to be completed by the fall of 2024.
