Acoustic Analysis of Slag Foaming in the BOF

The control of slag foam that is produced during the Basic Oxygen Furnace (BOF) process has been subject significant research. behaviour foams complex. Hence, in dynamic BOF challenging. Acoustic analysis one most promising methods for indirect measurement height. This paper reviews different studies on fundamental acoustics liquid and various acoustic related to determining height process. Studies have carried out using both cold water models plant trials, where measurements taken directly from were analysed. These showed attenuation sound through was influenced mainly by factors such as viscosity, bubble size, Current systems are said be 70 87 per cent accurate detecting and/or predicting slopping events BOF, though there a lack systematic data literature fully quantify this accuracy. There attempts combine with vibration image signals improve prediction BOFs. review substantiates accuracy current need address questions about foam, its reliance factors, relatability comparing model industrial data.
