7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Novel measurement systems for gauging the full three-dimensional burden surface and the two-dimensional top gas temperature distribution in a blast furnace in real time with an update period of a few seconds are presented in this paper. An introduction to the radar imaging principle for burden surface measurement and the fast acoustic tomography system for temperature distribution measurement are provided. Measurement results obtained at a test stand, during blast furnace relining, and during standard operation of multiple active voestalpine blast furnaces over a long period of several years are shown and validate the outstanding performance of the sensor systems. The possibility to monitor the blast furnace condition and improve the charging processing both offline and even in real time is discussed.
