Siemens Industry Sector is the world's leading supplier of innovative and environmentally friendly products, solutions and services for industrial customers. Due to the modular design of the new electric arc furnace, existing furnace installations can also be retrofitted with FAST DRI technology.įor more information about solutions for steel works, rolling mills and processing lines, please visit About Siemens The Simetal EAF FAST DRI is designed in combination with Siemens' Hot Transport System (HTS), enabling it to be fed with hot DRI at temperatures of around 600 degrees C. Slag-free tapping results in an enhanced alloys yield and better steel desulfurization, making installation of additional burners unnecessary. With the patented furnace advanced slag-free tapping system (FAST), charging, tapping and taphole refilling are possible under power-on conditions. Using this technology from Siemens, a 150-ton furnace can increase overall productivity by approximately 15 percent. The continuous supply of electrical energy during flat-bath operation not only improves productivity, but also avoids line harmonic distortions such as flicker. Now available in the North American market, the Simetal EAF FAST DRI is designed for a continuous melting process as electrical energy input and DRI are supplied during tapping, which shortens tap-to-tap times and reduces specific energy consumption.Ĭompared with conventional arc furnaces, tap-to-tap times can be reduced by up to 15 percent, energy consumption is cut by 20 kilowatt-hours per ton and electrode consumption falls by 10 percent. Simetal EAF FAST DRI Boosts Productivity of Electric Steel Production by up to 15 PercentĪTLANTA, - Siemens (NYSE: SI) today announced that it has developed a new electric arc furnace (EAF) specifically developed for direct reduced iron (DRI) melting. Siemens Introduces New Electric Arc Furnace for Direct Reduced Iron Melting Designed in combination with Siemens' Hot Transport System, furnace can be fed with hot DRI at temperatures of 600Â☌. Continuous supply of electrical energy during flat-bath operation avoids line harmonic distortions such as flicker, while Furnace Advanced Slag-free Tapping system enables charging, tapping, and taphole refilling under power-on conditions. With electrical energy input and direct reduced iron supplied during tapping, Simetal EAF FAST DRI supports continuous melting process.
