Since beginning of 2012 the newly founded Danieli Cento Met Swiss set-up is covering the field of very small steel plants fulfilling the investor targets of combining simple, reliable process equipment design with a consistent operational concept to produce commodity steel. Based on this vision the Danieli NanoMill concept for steel plants has been studied and developed. Danieli today is the only reliable plant supplier in position to offer the full panel of long product plants: i) the classical Danieli MiniMill configurations from 300.000 t/a to 1.500.000 t/a based on EAF melting; ii) the innovative MiDa - MicroMill Danieli concept with direct charging concept for plants in the range of 250.000 to 450.000 t/a based on EAF melting; iii) the reliable Danieli NanoMill concept based on either a newly developed NanoEAF or Induction Furnaces as melting units for a capacity range of typically 100.000 to 300.000 t/a. High flexibility of the complete NanoMill due to alternating operation of the primary melting units and the fully integrated downstream process lines. Looking particular into the needs of developing regions on the globe, it clearly turn out that we can find locations with a clear local need of long products, but with restriction in power quality and investment capability. Now there is an answer to such investment: the Danieli NanoMill. The Danieli NanoEAF with optimized size ranges called Nano2 (5 t to 15 t tap weight) and Nano3 (15 t to 35 t tap weight) has been developed with a new optimized design concept for such tap sizes allowing optimized Capex costs without compromising the necessary technical performance. The NanoEAF idea has been the driving force also of the overall NanoMill concept to be fully flexible in adjustment to raw materials, utility conditions and power availability and quality. The paper will present very interesting ideas on overall layout, Capex and OPEX comparisons and will present the first orders under implementation for these kind of mills. The response from the market shows that these kind of mills have a potential future and need the a professional attention to ensure the product quality and process requirements. The paper will also present the influence of proper raw material preparation via recycling tools like e.g. shredder; to be in position to efficiently operate such small melting units.
