Mathematical Model and Experiments on Reactive Powders Injection into a Metal Bath in a Pouring Ladle

Abstract

The paper presents a study of the physical and chemical processes that occur when treating liquid steel by inert gas and reactive powders, and a mathematical model using FEM to simulate the stirring state of steel as a result of the injection treatment. The mathematical model is based on the turbulent flow theory and it generates information about velocity conditions, the space distribution of the whirl energy and the current line distribution. The operating parameters are also determined with using this mathematical model.
