Physical Modeling of Metal Drop-slag Reactions with Gas Evolution
A room temperature model has been used to study the behavior of single reacting drops in liquids with gas evolution at the interface. This reaction is particularly important in light of the emerging bath smelting technologies, where a significant amount of iron-carbon drops are dispersed in an oxidizing slag. The present study was aimed at gaining a better understanding of the physical nature of the gas evolution reaction at the interface, which closely resembles the evolution of CO at the iron-carbon drop interface. Distinct regimes of behavior of the reacting drops have been observed, the primary variable being the drop size. The effect of the presence of surface active impurities in the slag on the nature of bubbles produced at the interface was also studied. Experiments were carried out at a lower pressure to study the effect of increased volume rate of gas evolution at the interface on the size distribution of bubbles.
