Siemens VAI Metals Technologies offers steelworks operators an electric arc furnace that has been specially developed for the use of DRI (direct reduced iron). The Simetal EAF FAST DRI is designed for a continuous melting process as electrical energy input and DRI are supplied during tapping. This shortens tap-to-tap times and reduces specific energy consumption. An overall productivity increase of around 15 percent can be achieved with a 150-ton furnace. The arc furnace has a modular structure, which also makes it possible to retrofit existing, conventional furnaces. With this new furnace concept Siemens underlines its technological leadership in electric steelmaking.
Simetal EAF FAST DRI from Siemens. The new arc furnace was specially designed for the use of direct reduced iron.
The Simetal EAF FAST DRI electric arc furnace has a tiltable lower vessel with an extensive liquid heel. The resulting continuous flat-bath operation allows electrical energy input and DRI feeding during tapping. Thanks to the patented furnace advanced slag-free tapping system (FAST), charging, tapping and taphole refilling are possible under power-on conditions. 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 ten percent. The continuous supply of electrical energy during flat-bath operation not only improves productivity, but also avoids line harmonic distortions such as flicker.
The continuous operation of the furnace offers a number of other benefits. Coal and oxygen injection as well as foaming slag control can be implemented even more precisely. Slag- free tapping results in an enhanced alloys yield and better steel desulfurization. Installation of additional burners thus becomes superfluous. Thermal stress on the refractory and structure materials also remains constant, prolonging their useful lives.
The Simetal EAF FAST DRI is designed so that, in combination with the Hot Transport System (HTS) from Siemens, it can also be fed with hot DRI at temperatures of around 600 °C. Thanks to the modular design of the new electric arc furnace, existing furnace installations can also be retrofitted with FAST DRI technology.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
