Improving Acoustic-Based Slag Foam Control Systems in the BOF

The control of slag foaming is vital to optimizing BOF performance. Acoustics systems have been applied to BOF monitoring but there is limited information about their accuracy and reliability. Improved understanding of the fundamental behavior of sound in slag foam will help resolve issues pertaining to reliability. The present study based on physical modeling experiments using scaled models showed that frequencies above 1,000 Hz were more sensitive to varying foam heights. This highlights the importance of the frequency bandwidths monitored for sonic systems. The prospective application of this knowledge on industrial systems to improve accuracy and reliability will be discussed.
