The viscosity of the reference powder (the mold powder applied in high-speed continuous casting in steel industry), as well as the viscosity of the above-mentioned samples, was evaluated using hot stage microscope analysis. The results of hot stage microscope analysis revealed that the viscosity of the reference powder was similar to that of low-fluorine and fluorine-free samples. Finally, a fluorine-free sample containing a combination of Fe2O3 and TiO2 was introduced as an optimized composition which could be a substitute for the currently-used mold powder applied in the continuous casting of steel with high speed, considering its similar viscosity to be that of the reference powder.}, keywords = {Mold powder,Viscosity,Hot Stage Microscope}, title_fa = {The Impact of MnO, Li2O, ZnO and TiO2 on Mold Powders Viscosity Using Hot Stage Microscope Analysis}, abstract_fa = {}, keywords_fa = {}, url = {https://journal.issiran.com/article_18528.html}, eprint = {https://journal.issiran.com/article_18528_47754f3fd888aff85674c3bf636e4dc4.pdf} }
