iEAF~? Technology: Recent Developments and Results at TenarisDalmine, Italy

摘要

Tenova's iEAF~? is an innovative system with the aim of dynamic control & optimization of the EAF. It incorporates off-gas analysis with the addition of continuous process measurement tools and detailed online models. Measurement tools & process models allow for a holistic approach to EAF optimization from the mass balance and energy balance sides. Details on the installation of instrumentation and hardware used to improve the measurement of off-gas flow and calculation of other variables is described as well as further changes to process modeling and dynamic measurement. Results from initial control and optimization trials on combustion control and results from chemical and thermal endpoint prediction are reported. Conclusions and future work, including further instrumentation and hardware additions, are also presented.
