Multiphase Modeling of Steel-slag Mass Transfer through Distorted Interface in Bottom-stirred Ladle

Abstract

A three-dimensional computational fluid-dynamics (CFD) model containing three phases: water, oil, and air was developed to study the mass transfer process at the slag-steel interface in the ladle. The transient mass transfer between slag and metal phases occurred only at the interface and the transient irregular distorted interface was considered. A more realistic concentration distribution and transient variation process of mass transfer in the bottom-blown ladle was obtained.
