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.
