Calculation of Physical Properties for Use in Models of Continuous Casting Process-Part 1: Mould Slags

This study presents a comprehensive analysis of the physical properties essential for modeling the continuous casting process, focusing specifically on mould slags. The objective is to enhance the accuracy of predictions in mold dynamics and defect mechanisms by leveraging mathematical models that require precise input data. A meticulous methodology is adopted to develop routines that calculate the necessary physical properties from the chemical composition of the materials involved. Given the wide variability in compositions of both steel and mould slag, the study emphasizes the importance of creating reliable estimation techniques. The models introduced establish correlations between chemical and physical properties, thereby facilitating better predictions of heat flux and powder consumption, critical for preventing defects such as slag entrapment and oscillation marks. Preliminary results indicate that the developed relationships provide significant insights into the interfacial tension at the metal/slag interface, offering a transformative perspective to the continuous casting process. This foundational work lays the groundwork for further advancements in the understanding and optimization of casting phenomena.
