SUSTAINTAP – Blast furnace sustained tapping practice

Blast furnace sustained tapping practice

Initial situation:

  • Unknown position and voidage of the dead man.
  • Uncertainty concerning liquid levels of iron and slag.
  • Hearth wear calculated only in 2D sections.
  • Influence of hearth flow on wear calculations.

Work topics in the project:

  • Estimation of position and voidage of the dead man from operational data.
  • Estimation of liquid levels from EMF data.
  • Calculation of the hearth wear under consideration of the hearth flow and dead man properties.

Expected results

  • Online models for liquid levels and dead man state.
  • 3D hearth wear model.
  • 3D hearth flow model as well as models of the iron – slag interface tilting and tap hole flow.
