Presentation Title Thermophysical Properties of Ladle Slag with Different SiO2 Content

Abstract Scope The demand of electric vehicles, driven by decarbonization policies, has increased the global production of electric steel, characterized by high silicon content. Producing this type of steel requires a carefully selected slag composition with high SiO₂ content. This study investigates the thermophysical properties of slag, including viscosity, surface tension, and density, with varying silicon oxide content. Silicon oxide, ranging from 1 to 20 wt%, was added to cleanness slags with a CaO/Al₂O₃ ratio of 1. The results indicate that increasing the silicon oxide content significantly influences the viscosity, density, surface tension, and degree of polymerization of the slags. Understanding these parameters and their dynamics enhances the control over slag-steel interactions in the steel ladle, thereby improving process efficiency and steel quality.
