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
