Description
This presentation introduces a scrap-aware adaptive electrode and process control concept for Electric Arc Furnaces (EAFs). The system performs an in-situ scrap classification based on process-integrated signals to identify scrap stratification, density distribution and expected melting behavior. These indicators drive an adaptive control layer that continuously adjusts transformer tap position, reactor step, and phase-specific current setpoints representing arc length. Control characteristics are automatically switched according to prevailing scrap conditions, improving arc stability across bore-down, melting, and refining phases. A simplified melting model estimates remaining scrap height and supports optimized burner coordination. Plant trials show improved arc stability, energy efficiency, and reduced melting time, particularly for heterogeneous scrap mixes.
