We are pleased to announce that our paper written by Mr. Kento Nakanishi (PhD. cand.) has been accepted and published in the international journal Metallurgical and Materials Transactions B, a leading journal in the fields of materials science and metallurgy.

In this study, we investigated fluoride-reduced mold fluxes, focusing on how chemical composition (the SrO/CaO ratio) and shear flow (rotation) affect their viscosity (fluidity) and crystallization behavior.

Our results revealed that adding SrO does not change viscosity in a simple, linear way; instead, the viscosity exhibits a non-linear response to composition changes. We also found that crystallization during cooling is strongly influenced by whether shear is applied, and that the primary crystalline phase can switch from cuspidine to akermanite depending on the flux composition.

These findings provide important insights into the relationship between structure, properties, and kinetics in mold fluxes. Ultimately, this work contributes to a deeper understanding of high-temperature materials and supports the development of more environmentally friendly continuous casting processes.

We would like to express our sincere appreciation to all co-authors and collaborators for their outstanding contributions to this research.
