MeltCon – Melt temperature control in electric arc furnace
Initial situation:
- Electric Arc Furnace has high demand of electrical and chemical energy.
- Precise end point control essential for energy efficient steelmaking.
- Models strongly depend on starting conditions.
- Spot measurements not meaningful in inhomogeneous melts.
Working topics:
- Continuous melt temperature monitoring during refining phase.
- Enhanced dynamic process control using measurement data.
- Develop strategies and model calculations for exact end point control.
- Evaluate performance of continuous measuring.
Results:
- Improve energy efficiency of EAF process.
- Avoid deviations from optimal treatment.
- Achieve tapping temperature and target analysis at same time.
- Improve working conditions.
