Abstract
- A transient 3D mathematical model is developed to study the surging auxiliary slag skimming process in molten iron ladle. A new mathematical model using the large eddy simulation is built for the gas–metal–slag three‐phase flow in the ladle. The Eulerian volume of fluid model is used for tracking the liquid–slag–air free surfaces, and the Lagrangian discrete phase model is used for describing the bubble movement. The procedure of bubble coming out of the liquid and getting into the air is modeled using a user‐defined function. The results show that optimizing the distance of the lance L and the injection volume Q can better the shape of the slag eye, increase the curvature radius of the slag eye on the side of the iron mouth, and broaden the area of the slag eye. At the same time, it can also improve the fluctuation of the slag layer and the liquid surface of molten iron, and reduce the splashing of molten iron and slag entrapment phenomenon, thus improving the slag skimming efficiency.
