MeltCon – Determining process conditions for online monitoring of temperature and carbon content in the electric arc furnace to optimise end point control

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.
