iEAF® Net Energy Control
Tenova’s i EAF® Dynamic Net Energy Control is based on novel sensors combined with mathematical models to achieve a mass energy balance. Heat control is based on real-time calculation of melting percent which is a ground-breaking innovation in the pacing of EAF operations.
Overview
iEAF® dynamic melting control uses fundamental thermodynamic and kinetic relationships along with traditional “kWh per ton” control logic to pace every heat the same way irrespective of the heat’s actual energy efficiency. Using novel sensors combined with mathematical models to achieve a mass energy balance. Novel sensors include:
Off-gas temperature/pressure/flow-rate
Slag and liquid weight measurement or calculation
iEAF® dynamic refining control uses endpoint detection to facilitate temperature and carbon conditions to be reached in a dynamically optimized way. The module uses data from the novel sensors combined with Bath & Slag process control models to:
Dynamically monitor and evaluate refining scenarios
Dynamically optimize the refining path by selecting optimum chemical and energy profiles
Determine when the endpoint condition (T and C) is reached
