ECOPIants Technologies - Revolutionary Continuous S/EAF-Process and Innovative Energy Recovery Solutions

摘要

Metallurgical processes generate either hot and / or combustible exhaust gases which can be used for Energy Recovery. Along the process chain from steelmaking plants to processing lines we can find several process step's where heat is required and waste heat as well as combustible gases are also generated. Therefore SMS Siemag developed several technical solutions to recover the energy from hot off-gas (BOF, EAF, SAF) by evaporation cooled ducts or tailored waste heat boiler solutions, hot slabs by innovative heat exchangers, combustible exhaust gases by industrial power plant technologies. The revolutionary ARCCESS~R steady EAF (S/EAF~R) is the combination of best practice EAF and SAF technologies and enables the continuous (!) operation of the electric arc furnace. This leads to a 30% higher productivity with lower energy consumption. By continuous charging virgin DRI (hot or cold) or pig iron high quality steel grades can be produced. In addition we offer a holistic Energy Management System supporting plant managers to detect current potentials and maintain them in long term.
