To clarify the relationship between bubble sizes and slag foaming behavior, foaming height of molten slag containing FeO was investigated under gas injection with wide range of flow rate. The slag composition was changed considering the addition of direct reduced iron (DRI), and the bubble size was determined at various flow rates using the frequency of bubble formation. The measurement results revealed that the critical value of flow rate exists and at flow rates higher than the critical value, the bubble size tended to increase as the flow rate increases. Because the phenomena of slag foaming are significantly influenced by the bubble size, it is necessary to carefully consider the change in the bubble size in the estimation of the slag foaming index. Moreover, dimensional analysis was used to derive an expression for the slag foaming index considering the bubble size. [ABSTRACT FROM AUTHOR] |
