Local erosion of solids in contact with gas/liquid or liquid/liquid interfaces is well known in many process industries. In pyrometallurgical furnaces these erosion patterns are referred to as slag-line or flux-line erosion. In many attempts to model fluid flow in these furnaces the importance of Marangoni flows at the slag-metal interface have, to a large extent, been ignored completely. The results of modelling studies presented here show that these flows are of considerable significance and must be included in fluid flow simulations in order to account for the classical flux-line erosion profiles seen in many furnaces.
