SMS group’s CMT® technology is designed to create an energy-efficient steelmaking system. Scrap metal is charged into the electric arc furnace (EAF), where it is melted and refined into liquid steel. The low carbon footprint from the CMT® process is o further supported by advanced power electronics technology for the electric arc furnace (EAF).This technology minimizes fossil fuel usage during the melting process in terms of carbon/electrode consumption and electrical energy consumption. The entire CMT® mill is designed to be capable of operating fully on renewable energy, provided the local energy infrastructure ensures an efficient supply to the mill. 

Customer challenges addressed

  • Lowest CAPEX: Up to 15% savings, due to its compact design.
  • Flexibility in material charging with scrap, pig iron, HBI/DRI, depending on regional material availability
  • Lowest OPEX: Up to 55 Euro/t savings thanks to increased material yield due to no-scale formation, minimized crop ends and reheating by Elotherm induction furnace (IHF) before rolling
  • High yield: 99% total plant yield compared to a conventional rolling technology (up to 97% considering primary/secondary scale losses, crop ends and short bars)
  • Digitalization: Up to level 4 automation system for planning, control and coordination of the production plant areas. Advanced system connected to human-machine cooperation and sustainability
