OptiBlaFIns – Analysis of blast furnace hearth state

Initial situation:

• bad hearth condition influences energy consumption, operational stability, hot metal quality and productivity.
• from earlier research projects offline simulation tools are available which describe the complex prozesses in the BF hearth.

Working topics:

• operational data interpretation.
• extended modelling of BF hearth processes.
• online application of extended BF hearth monitoring models
• diagnose and control the Dead Man state

Results:

• investigate the actual liquid and solid flow within the hearth using DEM-CFD.
• improve understanding of localized wear events in the hearth
• improve hearth drainage and prolonging hearth life
• decrease energy consumption and raise productivity
