摘要：
The crucial role of foamed slag in improving the effectiveness of the arc furnace process is beyond any doubt. However, there is no consistent approach to the description of the slag foaming mechanism despite the wide application of this process in modern electric-arc furnaces. Aspects of assessing the effectiveness of slag foaming are considered. A new index characterizing the slag foaming rate is introduced. It allows determining the superficial gas velocity that ensures effective foaming of slag depending on its physical and chemical properties.
