Siemens Introduces New Electric Arc Furnace for Direct Reduced Iron Melting07:03 EST Thursday, January 19, 2012Simetal EAF FAST DRI Boosts Productivity of Electric Steel Production by up to 15 PercentATLANTA, Jan.19, 2012 /PRNewswire/ -- Siemens (NYSE: SI) today announced that it has developed a new electric arc furnace (EAF) specifically developed for direct reduced iron (DRI) melting. 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. (Photo: )(Logo: )Compared 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. The continuous supply of electrical energy during flat-bath operation not only improves productivity, but also avoids line harmonic distortions such as flicker. Using this technology from Siemens, a 150-ton furnace can increase overall productivity by approximately 15 percent.With the patented furnace advanced slag-free tapping system (FAST), charging, tapping and taphole refilling are possible under power-on conditions. Slag-free tapping results in an enhanced alloys yield and better steel desulfurization, making installation of additional burners unnecessary.  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. Due to the modular design of the new electric arc furnace, existing furnace installations can also be retrofitted with FAST DRI technology.
