The influence of operational variables (such as gas flow rate, gas injection position and slag layer thickness) on phenomena like emulsification and slag-eye opening behaviour was studied with the help of a physical and mathematical model of an argon-stirred ladle, ellipse shaped and in reduced scale. Experiments on the physical model were carried out using water and kerosene simulating the steel and the slag, respectively. Such experiments were recorded on video. The same conditions and fluids employed in the physical model were simulated in the numerical model.
