Resumo
Q-ONE TECHNOLOGY, DEVELOPED AND PATENTED BY DANIELI, REPRESENTS A BREAKTHROUGH INNOVATION IN POWER TRANSFER TO THE ARC FURNACE. BY USING LATEST POWER ELECTRONICS, THE Q-ONE IS CAPABLE OF HANDLING THE IRREGULAR LOADS OF THE ELECTRIC ARC FURNACES AND CONTROL IN REAL-TIME ARC VOLTAGE, CURRENT AND FREQUENCY. ALSO, Q-ONE MINIMIZES THE IMPACT ON THE GRID COMPARED TO THE TRADITIONAL SOLUTION, LIMITING THE NEED OF ADDITIONAL COMPENSATION SYSTEMS. THE UNIQUE ARC CONTROL FEATURES OF THE Q-ONE IMPROVE FURNACE PERFORMANCES, REDUCING ELECTRIC CONSUMPTION AND ELECTRODE CONSUMPTION, EXTENDING REFRACTORY LIFE, AND MINIMIZING MAINTENANCE COSTS. ON TOP OF THIS, THE Q-ONE TECHNOLOGY ALLOWS FOR DIRECT CONNECTION OF RENEWABLE ENERGY SOURCES SUCH AS PHOTOVOLTAIC TO THE EAF, OPENING AN EXCITING OPPORTUNITY FOR AN EVEN MORE SUSTAINABLE AND DIGITAL MELTING PROCESS. MORE THAN 40 REFERENCES PROVE THE EXCEPTIONAL INTEREST IN THIS INNOVATION IN STEELMAKING. THIS PAPER, AFTER A BRIEF INTRODUCTION OF THE Q-ONE PRODUCT, PROVIDING TECHNICAL DESCRIPTIONS OF ELECTRICAL EQUIPMENT AND CONTROL FUNCTIONS, ILLUSTRATES THE RESULTS ACHIEVED ON THE RECENT APPLICATION OF Q-ONE TECHNOLOGY TO BOTH EAF AND LF. PARTICULAR ATTENTION IS DEDICATED TO THE PRINCIPLES OF ARC FREQUENCY VARIATION—THE UNIQUE FEATURE OF Q-ONE TECHNOLOGY—THE FREQUENCY CONTROL STRATEGY ADOPTED, AND THE BENEFITS OF THIS EMPOWERED EAF PROCESS CONTROL.
