Q-One Power Feeder Enhances EAF Performance at Shinkasai Steel, Japan
Danieli Automation’s cutting-edge Q-One power feeder has been successfully implemented at Shinkasai Steel, a prominent Japanese steel manufacturer based in Osaka. This marks the second installation of the Q-One system in Japan, following its earlier deployment at Tokyo Steel in 2021. The installation at Shinkasai Steel further demonstrates the technological advancements driving the efficiency of Electric Arc Furnace steelmaking in the country.
Impressive Operational Efficiency and Performance
The integration of the Q-One power feeder into Shinkasai Steel’s EAF system has had an immediate and significant impact on production. The steelmaker achieved the Final Acceptance Certificate (FAC) just 28 days after startup, a remarkable feat that underscores the seamless operation and quick results the Q-One system delivers. Within this short period, all performance tests were successfully completed, solidifying the efficiency of the new system.
Energy Efficiency and Power Savings
One of the standout features of the Q-One power feeder is its ability to operate with variable frequency down to 20 Hz at full power, which contributes to highly efficient steel melting. This capability leads to robust stirring within the liquid steel bath, promoting better metal quality and heat distribution. In turn, this reduces the overall power consumption during steelmaking, leading to an energy savings of approximately 8%.
The system’s energy efficiency is particularly crucial in areas with challenging grid conditions. The Q-One power feeder’s design ensures that its operation has a minimal impact on the power grid. Unlike many traditional systems, it doesn’t require additional compensation systems. This makes it particularly valuable for industrial areas with weaker power networks, such as the Osaka Sakai industrial region, where Shinkasai Steel is located.
The power system’s minimal grid impact is quantified by its Pst flicker value of about 0.5 and harmonics levels at just 30% of the maximum allowed. These figures represent a drastic reduction in electrical disturbances typically associated with high-power industrial operations, making the system highly compatible with sensitive grid environments.
Expanding the Q-One System in Japan
Following the successful implementation at Shinkasai Steel, Danieli Automation is poised to expand the use of Q-One systems further across Japan. Two additional Q-One installations are planned for Chiyoda Steel in Tokyo and JFE B&S in Himeji. These upcoming installations are expected to deliver similar benefits, further establishing the Q-One system as a key enabler of efficient, sustainable steel production in the region.
Technology Leading the Way
The success of the Q-One power feeder at Shinkasai Steel highlights the growing importance of technological innovation in the steelmaking industry. As manufacturers face increasing pressure to reduce energy consumption and improve operational efficiency, systems like the Q-One power feeder are becoming integral to achieving these goals. Its ability to provide stable and efficient operation in challenging grid conditions while reducing energy costs makes it an attractive option for steel producers worldwide.
Danieli’s commitment to innovation in the steel industry continues to push the boundaries of what is possible in electric steelmaking. With the continued success of the Q-One system in Japan, Danieli is solidifying its position as a leader in sustainable steel production technologies.
The Future of Steelmaking Efficiency
As steel producers strive for greater efficiency and sustainability, the role of digital tools and advanced power systems becomes ever more crucial. The Q-One power feeder represents a significant leap forward in steelmaking technology, offering not only energy savings but also operational improvements and minimal environmental impact. With more installations planned, the future of steel production looks set to benefit from increasingly efficient and sustainable technologies like the Q-One power feeder.
